The recent proliferation of Internet-enabled technology has sig-
niﬁcantly changed the way adolescents encounter and consume
sexually explicit material. Once conﬁned to a personal computer
attached to a telephone line, the Internet is now available on lap-
tops, mobile phones, video game consoles, and other electronic de-
vices. With the growth of the Internet has come easier and more
ubiquitous access to pornography. The purpose of this article was
to review the recent (i.e., 2005 to present) literature regarding the
impact of Internet pornography on adolescents. Speciﬁcally, this
literature review examined the impact of Internet pornography on
sexual attitudes, beliefs, behaviors, and sexual aggression. The au-
thors also discuss the literature related to the inﬂuence of sexually
explicit Internet material on self-concept, body image, social devel-
opment, as well as the expanding body of research on adolescent
brain function and physical development. Finally, recommenda-
tions for future research were discussed, based on this literature
The proliferation and mainstreaming of pornography over the last 2 decades,
especially through the Internet, have inﬂuenced youth culture and adoles-
cent development in unprecedented and diverse ways (L¨

ansson, 2010; McNair, 2002; Paul, 2005; Peter & Valkenburg, 2007).
Internet-enabled devices have indiscriminately allowed people of all ages to
encounter, consume, create, and distribute sexually explicit content, and a
growing body of data reveal these phenomena are increasingly common for
adolescents worldwide (Flood, 2007; H¨
om-Nordin, Sanberg, Hanson,
en, 2006; Lo & Wei, 2005; Wolak, Mitchell, & Finkelhor, 2007). Relative
to other media, the Internet is considered a highly sexualized environment
(Cooper, Boies, Maheu, & Greenﬁeld, 1999; Peter & Valkenburg, 2006a),
and research has shown signiﬁcant increases in the number of youth who
are intentionally or accidentally encountering pornographic material online
(Mitchell, Wolak, & Finkelhor, 2007; Wolak et al., 2007).
Given these circumstances, one may assume that adolescents’ access to
pornography via the Internet is unmatched by any other medium (Mitchell,
Wolak, & Finkelhor, 2007); the volume and range of sexually explicit con-
tent available on the Internet is remarkable. The evolving nature of techno-
logically mediated pornographic content (e.g., real-time and interactional)
provides novelty and variety at unprecedented speeds (Coopersmith, 2006).
Additionally, the risk of cyberbullying, sexual victimization, or harassment
from others is real and pervasive (Federal Bureau of Investigation, 2011).
Furthermore, the Internet is present and prioritized in the lives of many
youth (Lenhart, Ling, Campbell, & Purcell, 2010; Lenhart, Purcell, Smith, &
Zickur, 2010; Mitchell et al., 2007). For example, in the United States, 93%
of all adolescents ages 12 to 17 use the Internet; 63% go online daily and
36% are online several times a day (Lenhart, Purcell et al., 2010). The World
Internet Report surveyed 12 to 14 year olds from thirteen different countries
and found that 100% of British youth, 98% of Israeli youth, 96% of Czech
youth, and 95% of Canadian youth reported using the Internet regularly
(Lawsky, 2008). Given that the average American teen owns 3.5 mobile
devices (Lenhart, Purcell et al., 2010), it can be assumed a great deal of
their online activity is portable, and therefore, largely unmonitored (Roberts,
Foehr, & Rideout, 2005).
This increasingly ubiquitous access to the Internet can be positive; for
example, people of all ages are turning to this medium for information on
sexual education and sexual health (Barak & Fisher, 2001), social connection
(Cooper, Boies, Maheu, & Greenﬁeld, 1999), work, shopping, entertainment,
news, and academics. On the other hand, unmonitored access for youth
raises genuine concerns in light of the potential risks (Federal Bureau of
Investigation, 2011); adolescents often lack the risk attenuation needed to
discern and manage online dangers and content in safe and healthy ways
(Delmonico & Grifﬁn, 2008). There is also a small, but growing, body of re-
search that indicates adolescents are increasingly struggling with compulsive
Internet use (CIU) and compulsive behaviors related to Internet pornogra-
phy and cybersex (Delmonico & Grifﬁn, 2008; Lam, Peng, Mai, & Jing, 2009;
Research Review: Impact of Internet Pornography on Adolescents 101
Rimington & Gast, 2007; van den Eijnden, Spijkerman, Vermulst, van Rooij,
& Engels, 2010).
A review of the literature during this period indicates signiﬁcant in-
creases in the volume of research examining CIU and compulsive adolescent
sexual behavior related to pornography, as well as a diversity in the areas
of the world studying these phenomenon, such as: China (Fu, Chan, Wong,
& Yip, 2010), the Netherlands (van den Eijnden et al., 2010), the United
Kingdom (Gillespie, 2008), the United States (Sussman, 2007), and Taiwan
(Yen et al., 2009). Consequently, it may be inferred that the impact of Inter-
net pornography on adolescents, including compulsive, addictive, and even
criminal behavior, is a global trend not isolated to any one particular culture
As their Internet use increases, it is important to understand the systemic
impact of this medium, and speciﬁcally exposure to pornographic stimuli,
on adolescent development. Adolescent development, for the purposes of
this article, is understood to involve critical and signiﬁcant changes across
a multitude of domains: physical, emotional, cognitive, social, spiritual, and
sexual. Consequently, adolescents are considered one of the most susceptible
audiences to sexually explicit content.
While it is developmentally normal for adolescents to have sexual curiosity,
the extent of easy, free, and unmonitored access to pornography on the
Internet begs the question: what impact, if any, does exposure to Internet
pornography have on adolescents? The goal of this article is to examine
recent literature (i.e., 2005 to present) related to the impact of pornography
The research has described a number of indirect effects that pornog-
raphy may have on children (Manning, 2006), such as parents’ compulsive
use of the Internet for sexual arousal (Schneider, 2003) and the quality of
family relationships (Perrin et al., 2008; Schneider, 2003). For example, on-
line sexual activity has been linked to marital dissatisfaction, divorce, and
other challenges and stresses on the family system (Reid, Carpenter, Draper,
& Manning, 2010; Schneider, 2003). However, the goal of this article is not
to examine indirect effects; instead, the purpose of this review is to describe
direct relationships between adolescents’ consumption of Internet pornogra-
phy and associated phenomena. Our goal is to highlight the current body of
research in an objective, succinct, and coherent way, making it accessible to
educators, counselors, policy makers, parents, and other vested stakeholders.
Our purpose is not to make moral judgments regarding the consumption
of pornography, but rather to highlight the direct inﬂuences pornography has
102 E. W. Owens et al.
on the developmental processes of children, and on adolescents speciﬁcally.
Due to the ubiquitous nature of the Internet as well as online sexually
explicit material, this review is warranted and long overdue. There is a wealth
of research on the inﬂuence of online sexually explicit material on adults;
however, there is a similar dearth of literature on children and adolescents,
in part, due to the legal and ethical considerations involved. In the United
States, as in many other countries, it is illegal to distribute sexually explicit
material to minors or knowingly expose them to it, thereby making many
types of scientiﬁc inquiry difﬁcult.
The goal of this review is to examine the research related to the impact
of online sexually explicit material on adolescents; speciﬁcally we examine
their attitudes, beliefs, behaviors, self-concept, social development, and brain
development. These areas were selected due to their repetition in the cur-
rent literature, and in the case of brain development, because of the obvious
and central role the brain plays in the cognitive, behavioral and emotional
responses commonly cited in the research. Finally, we will provide recom-
mendations for future research based on this review.
Two issues regarding this literature review are worthy of note; ﬁrst, we
have included research in which the authors may not have examined online
pornography speciﬁcally, but pornography in various media. We did this with
the assumption that the Internet has become a universally accepted source
of information, especially for adolescents, and that exposure to pornogra-
phy may be assumed to occur on the Internet as frequently, if not more
frequently, than through any other medium. Also, there are other topics that
could be explored; however, the current body of research provided the pa-
rameters for this review, and emphasis has been placed on research that
examines non-clinical and non-compulsive Internet pornography exposure.
Before examining the impact of Internet pornography on adolescents, it is
ﬁrst necessary to provide deﬁnitions of the terminology used in the literature,
and in this review. Researchers who have studied the inﬂuence of pornog-
raphy on youth have examined a wide range of ages; however, there are
some commonalities regarding the deﬁnition of the term adolescent. Studies
of this type have examined the impact of pornography on individuals as
young as 10 (Ybarra & Mitchell, 2005) and as old as 22 (Braun-Courville
& Rojas, 2009). However, the majority of authors have focused their deﬁ-
nition of adolescent to those 13–18 years of age (e.g., Hunter, Figueredo,
& Malamuth, 2010; Mesch, 2009; Peter & Valkenburg, 2006a, 2006b, 2008a,
Another critical deﬁnition is the term pornography, or sexually explicit
material. Through a review of the literature, it becomes clear there are almost
Research Review: Impact of Internet Pornography on Adolescents 103
as many deﬁnitions for sexually explicit material as there are individuals who
have studied it. The challenge in deﬁning the term pornography was, per-
haps, most famously described by the United States Supreme Court Associate
Justice, Potter Stewart. In his concurring opinion in Jacobellis v. Ohio (1964),
Justice Stewart described his effort to deﬁne hard core pornography when
he wrote, “I shall not today attempt further to deﬁne the kinds of material I
understand to be embraced within that shorthand description; and perhaps
I could never succeed in intelligibly doing so. But I know it when I see it”
(“Concurring Opinion of Mr. Justice Stewart,” para. 1).
There are various descriptions of the term pornography throughout the
literature. Peter and Valkenburg (2009) deﬁned sexually explicit material
as content “that depicts sexual activities in unconcealed ways, often with
close-ups with (aroused) genitals and of oral, anal, or vaginal penetration”
(p. 408). Tsitsika et al. (2009) deﬁned pornographic Internet sites as “illicit
Internet sites portraying sexual behaviors and practices” (p. 546). Braun-
Courville and Rojas (2009) deﬁned sexually explicit websites as those that
“describe people having sex, show clear pictures of nudity or people having
sex, or show a movie or audio that describes people having sex” (p. 157).
Reid and colleagues (2011) deﬁned pornography as material that (a) creates
or elicits sexual feelings or thoughts, and (b) contains explicit images or
descriptions of sexual acts involving the genitals (e.g., vaginal or anal inter-
course, oral sex, masturbation, etc.). However, for the purpose of this review,
we will use the deﬁnition provided in the 1986 Attorney General Commis-
sion on Pornography. In that document, pornography was deﬁned as any
material that “is predominantly sexually explicit and intended primarily for
the purpose of sexual arousal” (McManus, 1986, p. 8).
Finally, some attention should be given to the concept of the Internet.
As technology advances faster than academics can study it, our notion of
media, social networking, and the Internet is constantly changing. Not long
ago, the Internet was something that could only be accessed with a computer
and an Internet Service Provider. Recently, tablet computers, smart phones,
and other electronic devices have added ubiquity to electronic communica-
tion and the Internet. For example, a recent study found that one in three
teenagers sends more than 100 text messages a day and 15% send more than
200 a day, or 6,000 a month (Lenhart et al., 2010). Four percent of teens have
sent a sexually suggestive text message, which are often nude photographs,
and 15% of this age group has received a sexually suggestive text (Lenhart,
The studies found in the literature largely fail to deﬁne the term Inter-
net, in part because these new technologies are continuously evolving and
growing in prominence. For the purpose of this review, it can be assumed
that the term Internet largely refers to the use of a personal computer or
similar device to access the World Wide Web. However, it should be noted
that some adolescents who have participated in the studies reviewed in this
104 E. W. Owens et al.
article may have accessed the Internet from a mobile phone, tablet computer,
video game console, or other electronic device.
IMPACT ON ATTITUDES AND BELIEFS
Recent research suggests a relationship exists between adolescents who are
exposed to Internet pornography and the acquisition of a variety of sexual
beliefs. Peter and Valkenburg (2008b) argue that sexually explicit material
can offer numerous sexual attitudes to viewers, and that these beliefs may
differ from those instilled in adolescents by their families and schools. This
dissonance, or conﬂict in sexual beliefs, is attributed to increased sexual
uncertainty (Peter & Valkenburg, 2008b).
Tsitsika et al. (2009) conducted a cross-sectional study among Greek
adolescents (N=529) in an effort to explore potential implications for the
use of sexually explicit material; ﬁndings suggested that Greek adolescents
who are exposed to sexually explicit material may develop “unrealistic at-
titudes about sex and misleading attitudes toward relationships” (p. 549).
Additionally, Peter and Valkenburg (2010) used data from a three-way panel
study among 959 Dutch adolescents to address two dimensions of perceived
realism: social realism and utility. The authors deﬁned social realism as, “the
extent to which the content of SEIM [sexually explicit Internet material] is
perceived to be similar to real-world sex” (pp. 376–77) and utility as, “the
extent to which adolescents perceive SEIM as a useful source of information
about sex and as applicable to the real world” (p. 377). They also examined
the inﬂuence of sexually explicit material on instrumental attitudes toward
sex, that is, “the notion of sex as primarily physical and casual rather than
affectionate and relational” (p. 375). This study suggests that as adolescents
are more frequently exposed to sexually explicit material, their perceptions
of the social realism and the utility of sexually explicit material increase.
The study also suggests that the greater adolescents’ perceptions of social
realism and utility of sexually explicit material, the greater their instrumental
attitudes toward sex.
However, a qualitative study conducted by L¨
ansson (2010) contradicts Peter and Valkenburg’s ﬁndings. L¨
artenson and M˚
ansson collected data from an adolescent population (N=
51) in Sweden; these data indicated the majority of participants were able
to distinguish between the fantasy of sexually explicit material and real-life
sexual interaction. However, the research participants acknowledged that
the ideals and pornographic scripts presented in sexually explicit material
do inﬂuence young people.
Additional research has shown that exposure to sexually explicit mate-
rial is a normative experience among adolescents who are following tradi-
tional developmental trajectories regarding sexual curiosity (Sabina, Wolak,
Research Review: Impact of Internet Pornography on Adolescents 105
& Finkelhor, 2008; Svedin, Åkerman, & Prieve, in press; Ybarra & Mitchell,
2005). In a study of emerging adults in the United States (N=813; M=
20-years-old), Carroll et al. (2008) found that 67% of males and 49% of fe-
males agreed that viewing sexually explicit material is an acceptable way to
express one’s sexuality. L¨
artenson and M˚
ansson (2010) argued that
the cultural context surrounding pornography use had been signiﬁcantly nor-
malized in recent years, having shifted from something that was “regarded
as shameful and morally reprehensible to something socially accepted” (p.
576). In light of these ﬁndings, it is interesting to note that L¨
ansson (2010) found the participants’ views and beliefs about pornog-
raphy differed greatly depending on the degree to which they related to
societal norms regarding sex, gender, relationships, and sexual violence. In
this study, the authors found no difference related to the age or gender of
In a recent study of male Swedish high school students (N=2015),
Svedin et al. (in press) supported the ﬁndings that frequent male viewers
of sexually explicit material had more liberal or positive attitudes towards
sexually explicit material than those who viewed pornography less frequently
or not at all. This study also suggested that frequent viewers of sexually
explicit material believed using such material could create a more stimulating
sex life for those consumers.
Peter and Valkenburg (2008a) were the ﬁrst in this review to investigate
the relationship between adolescents’ exposure to sexually explicit material
and sexual preoccupancy, deﬁned as “a strong cognitive engagement in
sexual issues, sometimes at the exclusion of other thoughts” (p. 208). Peter
and Valkenburg (2008a) surveyed 962 Dutch adolescents three times over
the course of 1 year. Their study found that “the more frequently adolescents
used SEIM, the more often they thought about sex, the stronger their interest
in sex became, and the more frequently they became distracted because of
their thoughts about sex” (Peter & Valkenburg, 2008a, p. 226). The results
of this study further suggested that “sexual arousal as a result of exposure to
SEIM may cue sex-related cognitions in memory. ...and may eventually lead
to chronically accessible sex-related cognitions, that is, sexual preoccupancy”
In a study examining connections between the use of sexually explicit
material and attitudes of Taiwanese adolescents, Lo and Wei (2005) used hi-
erarchical regression analyses to determine that exposure to sexually explicit
material on the Internet had a greater inﬂuence on permissive sexual attitudes
than all other forms of pornographic media. In the United States, a similar
study was conducted by Braun-Courville and Rojas (2009) that examined
the inﬂuence of sexually explicit material on adolescents’ sexual attitudes
and behaviors. Braun-Courville and Rojas found that the more frequently an
adolescent is exposed to sexually explicit material, the greater their sexually
106 E. W. Owens et al.
In 2009, Brown and L’Engle conducted a longitudinal study that con-
ﬁrmed a relationship between permissive sexual attitudes and exposure to
sexually explicit material. In addition, the authors also found a relationship
between adolescent exposure to sexually explicit material and less progres-
sive gender role attitudes for both males and females. For example, Brown
and L’Engle’s study indicated that male dominance and female submission
are gender roles that are reinforced through sexually explicit material.
Beliefs of women as sex objects are deﬁned by Peter and Valkenburg
(2009) as “ideas about women that reduce them to their sexual appeal in
terms of their outer appearance and their body (parts)” (p. 408). Peter and
Valkenburg (2009) state that “such notions also entail a strong concern with
women’s sexual activities as a main criterion of their attractiveness and focus
on women as sexual playthings that are eager to fulﬁll male sexual desires”
(p. 408). Peter and Valkenburg (2007) published a study of Dutch adolescents
(N=745) that investigated the relationship between exposure to sexually
explicit material and perceptions of women as sex objects. Their study found
that increased exposure to sexually explicit material increased the likelihood
that adolescents, regardless of gender, would view women as sex objects. In
a later study designed to clarify these ﬁndings, Peter and Valkenburg (2009)
determined that viewing women as sex objects was related to increased
frequency in the consumption of sexually explicit material. It is unclear how
adolescent females are impacted by viewing other females, and possibly even
themselves, as sex objects. In short, these ﬁndings suggest that “adolescents’
exposure to SEIM was both a cause and a consequence of their beliefs that
women are sex objects” (p. 425).
Lo and Wei’s (2005) study of 2,001 Taiwanese students demonstrated a
relationship between adolescents’ exposure to sexually explicit material and
positive attitudes toward premarital and extramarital sexual relations. Later
studies conducted in Europe and the United States supported these ﬁnd-
ings. A 2005 quantitative study by H¨
om-Nordin, Hanson, and Tyd´
examined the use of sexually explicit material and attitudes about casual sex
among Swedish adolescents (N=718). This study found participants who
consumed sexually explicit material possessed positive attitudes toward ca-
sual sex. These ﬁndings were supported again a year later in a qualitative
study among Swedish adolescents (N=18). In this study, H¨
et al. (2006) found that Swedish adolescents who consumed sexually explicit
material expressed positive attitudes about having causal sex with a friend.
Peter and Valkenburg (2006a) also surveyed Dutch adolescents (N=
471) in order to explore the use of sexually explicit material and the forma-
tion of sexual attitudes. The authors found that adolescents with more pos-
itive attitudes toward recreational sex used sexually explicit material more
frequently. Within this study, however, it remains unclear if “adolescents
with more recreational attitudes toward sex use sexually explicit online ma-
terial more frequently, or that recreational attitudes and exposure to sexually
Research Review: Impact of Internet Pornography on Adolescents 107
explicit online material inﬂuence each other reciprocally” (Peter & Valken-
burg, 2006a, p. 654). A subsequent study by Peter and Valkenburg (2008b)
also indicated a relationship between adolescent exposure to sexually ex-
plicit material and positive attitudes related to engaging in uncommitted
sexual exploration. Finally, in the United States, Braun-Courville and Rojas
(2009) posit that adolescents who are more frequently exposed to sexually
explicit material are more likely to accept the notion of casual sex.
There is agreement in the literature suggesting that adolescents can learn
sexual behaviors from observing the behaviors depicted in sexually explicit
material (Alexy, Burgess, & Prentky, 2009, H¨
om-Nordin et al., 2006;
en, Hanson, & Larsson, 2009; Hunter et al., 2009).
om-Nordin et al. (2006) supported previous ﬁndings that adolescents
believe sexually explicit material might serve as a source of knowledge but,
at the same time, distorts their images of sexuality. This study “extended
these ﬁndings by revealing that pornographic media conveyed expectations
and demands regarding what to do” (p. 391).
A 2005 study, conducted by Lo and Wei, examined the relationship be-
tween exposure to sexually explicit material and sexual behaviors of 2,001
Taiwanese adolescents. This study indicated that exposure to sexually ex-
plicit material increased the likelihood that adolescents will accept and en-
gage in sexually permissive behaviors. These ﬁndings are further supported
by Braun-Courville and Rojas (2009), Brown and L’Engle (2009), Lam and
Chan (2007), and Peter and Valkenberg (2006a, 2007, 2008b).
om-Nordin et al. (2005) examined the sex lives and pornogra-
phy consumption of high school students (N=718) in Sweden. Ninety-eight
percent of male and 76% of female respondents reported having consumed
pornography, 75% of the overall sample had engaged in sexual intercourse,
and 71% had used a contraceptive at ﬁrst intercourse. Having intercourse
with a friend, group sex, oral sex, and anal sex were all associated with fre-
quent exposure to sexually explicit material. In addition, 71% of adolescents
believed that sexually explicit material inﬂuenced the sexual behaviors of
peers but only 29% of adolescents believed that sexually explicit material
inﬂuenced their own sexual behaviors. This study also suggested that ado-
lescents who were more frequently exposed to sexually explicit material had
their ﬁrst experience of sexual intercourse at an earlier age than adolescents
who were not frequently exposed.
Several years later, Kraus and Russell (2008) expanded on the research
regarding exposure to sexually explicit Internet material and the age of ﬁrst
sexual experience, as well as the number of sexual partners. Participants
(N=437) who had Internet access reported signiﬁcantly younger ages of
108 E. W. Owens et al.
ﬁrst sexual experiences than those without Internet access; however, there
was no signiﬁcance when comparing the number of sexual partners. The
authors argue that “the Internet, which often promotes and sells sexually
explicit material, may be acting as an accelerant for earlier reported ages for
ﬁrst oral sex and ﬁrst sexual intercourse” (p. 166).
In 2009, Brown and L’Engle’s ﬁndings supported the studies of
om-Nordin et al. (2005) and Kraus and Russell (2008), speciﬁcally,
that early exposure to sexually explicit material increases the likelihood that
both male and females adolescents will engage in oral sex and sexual in-
tercourse earlier than their non-exposed peers. In this study, 66% of male
and 39% of female adolescents (N=967) reported that by the age of 14,
they had been exposed to sexually explicit material in the previous year.
In addition, 90% of the adolescent males reported having oral sex and 88%
reported having sexual intercourse.
These data suggest that adolescents are being exposed to sexually ex-
plicit material and engaging in a variety of sexual behaviors; some of which
are considered risky and problematic. Braun-Courville and Rojas’ (2009)
study of 433 adolescents indicated that those who use sexually explicit ma-
terial are more likely to engage in risky sexual behaviors such as anal sex,
sex with multiple partners, and using drugs or alcohol during sex. This study
was supported by Brown, Keller, and Stern (2009) who indicated that adoles-
cents who witness high risk sexual practices in sexually explicit material in
the absence of education on the potential negative consequences, are more
likely to engage in some form of high-risk sexual behavior themselves.
However, research published the next year found contradictory results,
speciﬁcally noting evidence that exposure to sexually explicit material was
unrelated to high-risk sexual behavior (Luder et al., 2010). Using a subpop-
ulation of Swiss adolescents (n=6054), these researchers found that “the
majority of risky sexual behaviors, such as early sexual initiation, multiple
sexual partners or a history of pregnancy were not associated with sexually
explicit material exposure whether it was voluntary or not” (p. 6).
Ybarra and Mitchell (2005) used data from the Youth Internet Safety Survey
to examine the pornographic seeking behavior of adolescents (N=1,501)
for cross sectional linkages in the use of sexually explicit material and psy-
chosocial characteristics. Their ﬁndings suggest that, for the majority of males,
frequent exposure to sexually explicit material cannot be linked to increased
levels of sexual aggression. However, among males “who have ‘predispos-
ing risk levels’ towards aggressive sexual behavior, those who frequently
consume pornography have more than four times greater levels of sexual
Research Review: Impact of Internet Pornography on Adolescents 109
aggression compared to their peers who infrequently seek out pornography”
A 2005 study by Malamuth and Huppin also focused on sexually explicit
material and its relationship to sexual aggression. They found that a male
adolescent who “possesses certain combinations of risk factors determines
how likely he is to be sexually aggressive following pornography exposure”
(p. 316). Focusing directly on violent sexually explicit material, Malamuth
and Huppin (2005) suggest that, not only are these higher risk adolescent
males “more likely to be exposed to such media but when they are exposed,
they are likely to be changed by such exposure, such as changes in attitudes
about the acceptance of violence against women” (p. 323–24).
A similar study was conducted by Alexy et al. in 2009. These authors
studied 160 sexually reactive children and adolescents (SRCA) and their asso-
ciations between sexually explicit material and sexually aggressive behavior.
“The SRCA population consists of high-risk individuals, speciﬁcally, young
individuals with a predisposition for aggression” (p. 450). Using a descrip-
tive, exploratory design, this study found that SRCAs who used sexually
explicit material were more likely “to engage in coerced vaginal penetration
and forced sexual acts such as oral or digital penetration, to express sexually
aggressive remarks (obscenities), and to engage in sex with animals” (p. 450)
than those who did not.
Brown and L’Engle (2009) conducted a longitudinal study of adolescents
(N=967) regarding sexual harassment as a manifestation of sexual aggres-
sion. Seventy-six percent of the adolescent male respondents acknowledged
having committed some form of sexual harassment and having used some
type of sexually explicit material. This study also found that males who were
exposed to sexually explicit material in early adolescence were more likely
to engage in sexual harassment in middle adolescence.
Using path analysis on data collected from adolescent males with a
history of physical sexual offenses (N=256), Hunter et al. (2010) found
childhood exposure to sexually explicit material may contribute “to antago-
nistic and psychopathic attitudes, likely the depiction of distorted views of
human sexuality and gloriﬁcation of promiscuity” (p. 146). Moreover, these
authors argued that because adolescents do not always have the opportu-
nity to counterbalance “real-life experiences with sexual partners.... they
are especially susceptible to internalization of distorted pornographic im-
ages of human sexuality and may act accordingly” (p. 147). The most recent
study concerning sexually aggressive behavior was a longitudinal study by
Ybarra, Mitchell, Hamburger, Diener-West, and Leaf (2011). Using data from
the Growing up with Media Survey, the authors examined longitudinal link-
ages between exposure to sexually explicit material and sexually aggressive
behavior. Data were collected over a span of 36 months and collected in
three waves. This study suggests that adolescents who are intentionally ex-
posed to violent sexually explicit material were six times more likely to be
110 E. W. Owens et al.
sexually aggressive than those who were not exposed. In contrast, adoles-
cents who were exposed to nonviolent sexually explicit material “are statisti-
cally equally likely to report sexually aggressive behavior compared to those
who report no consumption of nonviolent” (p. 14) sexually explicit material.
SELF-CONCEPT AND BODY IMAGE
There are limited data in the recent literature regarding the inﬂuence of Inter-
net pornography on adolescents’ self-concept and body image. While they
do not address the issue of pornography, Valkenburg and Peter (2011) as-
serted that communicating with others online may provide adolescents with
increased degrees of self-esteem. The Internet can provide three essential el-
ements of self-regard: control over one’s environment, approval from others,
and acceptance by others. These factors may speak to adolescents’ frequent
use of the Internet as a means of communication.
om-Nordin et al. (2006) employed qualitative methodology to
explore and describe the use of pornography by adolescents in an attempt
to gain a greater understanding of how this population uses pornography,
as well as its inﬂuence on them. Eighteen participants, 10 females and 8
males, shared their perceptions through individual interviews. The partici-
pants ranged in age from 16 to 23, and were recruited from a local youth
center in Sweden.
One theme identiﬁed in the interviews was how consumption of
pornography led young people to accept traditional gender roles, speciﬁ-
cally that of the male being in a position of power and the female being sub-
om-Nordin et al., 2006). Participants discussed the double-
standard reinforced in pornographic material; that is, women with multiple
partners are considered promiscuous, while men with multiple partners are
om-Nordin et al., 2006). Participants also discussed mes-
sages that are inferred from sexually explicit material as they relate to female
body image. One participant described this theme when she said, “well, the
girl should be small, thin, and you know ...inferior ...while the guy should
be muscular and superior” (H¨
om-Nordin et al., 2006, p. 390).
artenson and M˚
ansson (2010) also discussed these issues in
their qualitative study that examined the consequences of sexually explicit
material consumption on young adults. The study consisted of focus groups
and individual interviews with 51 participants aged 14–20, who were re-
cruited from schools in Southern Sweden. This study revealed a number of
themes related to the self-concept of emerging adults, one of which was that
young men are not necessarily interested in women who resemble women
in sexually explicit material. One female participant described this theme
when she stated, “there are guys who are sick and tired of silicon breasts
and do get tired of all this plastic” (L¨
artenson & M˚
Research Review: Impact of Internet Pornography on Adolescents 111
This study revealed a number of other pertinent results. The authors
described what they called a “pornographic script” for body type and sex-
ual performance that was reinforced by consumption of sexually explicit
artenson & M˚
ansson, 2010, p. 574). This script created
unrealistic and concerning expectations for both the males and females who
participated in this study. The men expressed insecurities about their ability
to perform sexually; the women expressed insecurities about body image
artenson & M˚
ansson, 2010). For example, the males in the study
discussed their concerns about being able to perform as well sexually, and
for the same duration, as the men in the pornography they viewed. In con-
trast, the women in the study felt that the women they saw in sexually explicit
material represented the ideal body type. One female participant replied that
she felt “very unattractive ... you can say that you aren’t inﬂuenced by this,
but no one can resist. You do want to have these ideal bodies” (p. 574).
Two other themes emerged that are of interest here. First, respondents
described a decrease in the consumption of sexually explicit material as
individual self-conﬁdence increased (L¨
artenson & Masson, 2010).
Participants also described an increased ability to “handle pornography sat-
isfactorily” if they had developed positive relationships with others, specif-
ically friends and family (L¨
artenson & Masson, 2010, p. 575). “It is
important to have someone to talk with. .... Friends are very important!”
said one male participant (L¨
artenson & Masson, 2010, p. 575).
A number of studies address the impact of sexually explicit material on ado-
lescents’ social development, attachment, and interpersonal relationships.
For example, Mesch (2009) used a 2004 sample of Israelis aged 13–18 in
an effort to describe social characteristics of pornography consumers. Us-
ing quantitative methodology, the study found that adolescents with higher
degrees of social interaction and bonding were not as likely to consume
sexually explicit material as were their less social peers (Mesch, 2009). Ad-
ditionally, Mesch found that greater quantities of pornography consumption
were signiﬁcantly correlated with lower degrees of social integration, specif-
ically related to religion, school, society, and family. The study also found a
statistically signiﬁcant relationship between pornography consumption and
aggressiveness in school, with higher degrees of consumption related to
higher levels of aggressiveness (Mesch, 2009).
The aforementioned study by Tsitsika et al. (2009) examined the impli-
cations of consuming Internet pornography. The data indicated a signiﬁcant
relationship between consumption of Internet pornography and social mal-
adjustment (Tsitsika et al., 2009). Speciﬁcally, adolescents who indicated
infrequent use of pornography were twice as likely have conduct issues as
112 E. W. Owens et al.
those who did not consume pornography at all. Also, frequent consumers
were signiﬁcantly more likely to indicate abnormal conduct issues as well as
borderline addictive Internet use (Tsitsika et al., 2009).
Ybarra and Mitchell (2005) not only examined the quantitative rela-
tionships between consumption of pornography and behavioral problems,
but also with depressive symptoms and emotional bonding with caregivers.
The study found a statistically signiﬁcant relationship between exposure to
sexually explicit material and delinquent behavior during the preceding 12
months (Ybarra & Mitchell, 2005). However these data also suggested a
difference between consumers of online pornography and those who use
other pornographic media. Speciﬁcally, children who consume sexually ex-
plicit material on the Internet are more likely to exhibit clinical symptoms of
depression and lesser degrees of bonding with caregivers than those who
consume pornography through other means (Ybarra & Mitchell, 2005).
Hunter et al. (2010) examined the relationship between exposure to
pornography prior to age 13 and four negative personality constructs. This
study surveyed 256 adolescent males with a history of sexual criminal behav-
ior; the authors found a relationship between early exposure to pornography
and antisocial behavior, likely the result of a distorted view of sexuality and
the gloriﬁcation of promiscuity (Hunter et al., 2010). In a similar study dis-
cussed previously, Alexy et al. (2009) studied the pornography consumption
patterns of juvenile sexual offenders as they related to various forms of ag-
gressive behavior. Those who were consumers of pornography were more
likely to display forms of aggressive behaviors such as theft, truancy, manip-
ulating others, arson, and forced sexual intercourse.
Finally, a study published by Lenhart (2009) conducted focus group
research with adolescents aged 12–18 regarding “sexting,” or sending sexual
text and images via mobile devices. During three focus groups, participants
were asked to describe the circumstances in which adolescents engage in
sexting, and their opinions of the practice. Three themes emerged from
the data, speciﬁcally that it is used: (a) as an exchange between romantic
partners, especially younger children who are not engaged physically; (b)
as an exchange between romantic partners, but the message is then sent to
others outside the relationship; and (c) as an exchange from one adolescent
to another in hopes of encouraging the formation of a romantic relationship
(Lenhart, 2009). Participants’ opinions ranged widely from a belief that it
is safer than engaging in a physical relationship, to the notion that it is
dangerous and potentially illegal (Lenhart, 2009).
PORNOGRAPHY USE AND THE ADOLESCENT BRAIN
Studies examining the impact of pornography consumption in the cor-
tical substrates in the brains of healthy control adolescent subjects are
Research Review: Impact of Internet Pornography on Adolescents 113
non-existent at this time. However, neuroscience research has advanced sev-
eral ﬁndings in the literature that have potential implications for work with
adolescents who are regularly exposed to sexually explicit material, and who
may be at risk for abnormal developmental trajectories. Some perspectives
on adolescent neurocortical vulnerability to pornography consumption are
drawn from the work of researchers in medicine and pathological gambling,
and from neuroscientists studying developmental psychology (Casey et al.,
2008; Chambers et al., 2003); these may be limited in their application to ado-
lescent consumption of pornography. Nevertheless, these perspectives can
provide a basis for hypothesis generation and avenues for future research in
the area of adolescent use of pornography.
A constellation of signiﬁcant change occurs during adolescence and
many of these changes are inﬂuenced by rewards (Somerville et al., 2010).
For adolescents, reward-seeking behaviors commonly occur in the pursuit
of money, novelty, excitement, and social connection, including peer-group
acceptance, sexual activity, and substance use (Steinberg, 2008). Develop-
mentally, risk-taking and reward-seeking decision-making behaviors pro-
mote growth and learning for a majority of adolescents. However, evidence
from the ﬁeld of neuroscience suggests that these tendencies may also be as-
sociated with a vulnerability to excess in high risk behaviors (Casey & Jones,
2010; Chambers et al., 2003; Doremus-Fitzwater, Varlinskaya, & Spear, 2010).
Differences in neurobiology between adolescent and adult brain sys-
tems have been well documented (e.g., Asato, Terwilliger, Woo, & Luna,
2010; Gogtay, et al., 2004). Although cortical dimensions of brain size in 6-
year-old children have reached approximately 90% of those found in adults
(Casey, Galvan, & Hare, 2005), changes continue to emerge for gray and
white matter substrates during adolescence and continue well into young
adulthood (Giedd, 2004; Gogtay et al., 2004; Sowell et al., 2003). For ex-
ample, signiﬁcant neuroanatomical differences emerge between adults and
adolescents in the frontal cortices and in the striatum (Sowell et al., 1999),
the regions generally presumed to be associated with executive control and
affect regulation (Alvarez & Emory, 2006; Costafreda, Brammer, David, &
Fu, 2008; Yurgelun-Todd, 2007). These differences, often measured through
functional magnetic resonance imaging (fMRI), have also been the impe-
tus for explanations about how adolescents may process reward stimuli in
the brain as compared to adults (e.g., Casey et al., 2008; Ernst, Romeo, &
Research suggests that deﬁcits in cognitive control and delayed mat-
uration in the prefrontal cortex of adolescents is responsible for poor de-
cision making, impulsivity, and affective challenges during teenage years
(Yurgelun-Todd, 2007). However, such models are incomplete and lack
convincing explanatory power related to high-risk adolescent behavior, es-
pecially given that most adolescents are capable of reasoning and understand
the risks associated with their behaviors (Reyna & Farley, 2006).
114 E. W. Owens et al.
An alternative and emerging neurobiological model argues subcortical
limbic systems and prefrontal top-down control regions must both be con-
sidered in order to fully understand vulnerability and poor decision making
among adolescents (Casey et al., 2008). In support of this model, a number of
studies provide evidence that adolescents may have hyper-activation of the
ventral striatal motivational circuit in response to rewards (Chambers et al.,
2003; Galvan et al., 2006) with one study showing greater striatal activa-
tion irrespective of reward receipt (Van Leijenhorst et al., 2010). Collectively,
research supporting this position suggests limbic systems mature much ear-
lier than prefrontal cortices throughout adolescent years, creating a bias for
emotionally salient stimuli over inhibitory control (Casey et al., 2008; Casey,
Jones, & Somerville, 2011; Galvan et al., 2006). Subsequently, protracted in-
tegration of prefrontal-striatal and inter-hemispheric connections associated
with a growing body of empirical literature may place adolescents at a higher
risk for developing problematic pornography use if exposed to sexually ex-
plicit content during teenage developmental years.
The rationale suggesting adolescent cortical vulnerability to pornog-
raphy misuse is, in part, based on the notion that sexual arousal elicited
by visual stimuli activates a constellation of neuropathways associated with
cognition, motivation, emotional arousal, and somatosensory experience
(Redoute et al., 2000). The participation of the amygdala and other limbic
structures in imaging studies of sexual arousal is believed to be associated
with emotional appraisal of sexual stimuli (Ferretti et al., 2005). Given these
observations, one may assume that pornography represents provocative and
emotionally salient stimuli that appeal to the adolescent brain. These stimuli,
in turn, disproportionately attend to opportunities for satiation of appetitive
reward at the expense of delayed gratiﬁcation often required for long-term
goal attainment. Unlike adults, adolescents are believed to lack sufﬁcient
maturation and integrity in frontal cortices necessary to exert cognitive con-
trol required to suppress sexual cravings, thoughts, and behaviors elicited
by pornographic content. This perspective is consistent with the belief that
cognitive control of impulses can be compromised in adolescents when self-
regulation interacts with salient motivation drives (Casey & Jones, 2010).
Further support for this position has been recently noted in a study where
adolescents exhibited enhanced sensitivity to appetitive cues as measured by
differential activation in the ventral striatum compared to prefrontal cortical
regions, and this sensitivity varied with appetitive load (Somerville, Hare, &
Research in the ﬁeld of information processing also provides insight in
to how pictorial stimuli such as pornography may be encoded in cortical re-
gions in a more indelible manner when compared to other stimuli (McBride
& Dosher, 2002). This effect, known as the picture-superiority effect, has
been well established in adults and more recently, evidence for this phe-
nomenon has been found in a study of adolescents (Whitehouse, Maybery,
Research Review: Impact of Internet Pornography on Adolescents 115
& Durkin, 2006). The essential notion of this phenomenon is that greater
levels of cortical processing and encoding occur, which favor recognition
and retention of pictures over other stimuli such as spoken words (Arieh
& Algom, 2002; Stenberg, 2006). Although the mechanisms of action for
this effect are unclear and likely differ based on the salience of the stimuli
(Amrhein, McDaniel, & Waddill, 2002), it is likely that pornographic images
are processed differently by the brain and leave a deeper impression com-
pared to verbal or word stimuli. Subsequently, it is important to note that
adolescents may process pictorial images quite differently than they do other
stimuli, which may have lasting implications for the ﬁeld of sexual education.
The structural deﬁcits in brain maturation of adolescents, and theories
such as the picture-superiority effect, offer insights into the ways adolescents
may be disproportionately vulnerable to negative consequences when ex-
posed to sexually explicit material. Additionally, research indicates that the
lack of experience and familiarity with novel adult behavior poses a great
risk (Romer, 2010). There is likely merit to the constellation of these per-
spectives, and these differences in opinion highlight the need for additional
research about the impact of pornography on the adolescent brain.
Although the literature does indicate inquiry into issues of Internet pornogra-
phy use among adolescents, the research is sparse and leaves more questions
than answers. Before tackling the content of what is lacking in the litera-
ture, we must ﬁrst turn our attention toward the process of conducting this
research, speciﬁcally research design and the protection of human subjects
through Institutional Review Boards (IRBs). Part of this process involves col-
lecting data on the risks and beneﬁts of this research in order to establish a
scientiﬁcally informed approach that can be used to educate IRB members
as they review studies that may fall outside their areas of expertise (Caskey
& Rosenthal, 2005; Mustanski, 2011).
Future studies would beneﬁt from research that incorporates more so-
phisticated methodologies that move beyond simple correlational analysis
and cross-sectional designs. For example, studies assessing mediating and
moderating variables, as well as causal effects, will add signiﬁcantly to the
existing body of knowledge. The inclusion of greater speciﬁcity about the
themes, content, and messages portrayed in pornography is needed and
such studies may be conducted using qualitative methods that offer greater
depth and rich data sources. It will also be necessary to conduct research
that provides greater understanding of differences related to gender, cultural
factors, minority status, and understudied populations such as lesbian, gay,
bisexual, and transgendered adolescents. As technological advances con-
tinue, researchers should consider the various electronic media (e.g., smart
phones, game consoles, tablet computers) used to consume pornography
116 E. W. Owens et al.
and the emerging trends toward technology use production and distribution
of one’s own pornography (e.g., sexting, podnography, YouTube videos,
Although some work has been done to understand the characteristics
associated with adolescents who consume pornography, future studies may
consider typologies among this population and whether pornography is
viewed accidentally or intentionally. Thresholds may enhance understanding
about youth who could be vulnerable to problematic pornography use, and
outcome studies highlighting clinical methodologies would make a signiﬁ-
cant contribution to the ﬁeld. Future research should continue to investigate
pornography consumption among adolescents in the context of developing
attitudes and beliefs about human sexuality (e.g., sex education or sexual
identity). Sexual health and sexual risks should also be considered with
an increased focus on neurobiological development and the emotional and
psychological well-being of adolescents who consume pornography. Finally,
global studies are greatly needed to understand how these various relation-
ships impact society from a systemic perspective.
Increased access to the Internet by adolescents has created unprece-
dented opportunities for sexual education, learning, and growth. Conversely,
the risk of harm that is evident in the literature has led researchers to in-
vestigate adolescent exposure to online pornography in an effort to eluci-
date these relationships. Collectively, these studies suggest that youth who
consume pornography may develop unrealistic sexual values and beliefs.
Among the ﬁndings, higher levels of permissive sexual attitudes, sexual pre-
occupation, and earlier sexual experimentation have been correlated with
more frequent consumption of pornography. Researchers have had difﬁculty
replicating these results, however, and as a result the aggregate literature has
failed to indicate conclusive results. Nevertheless, consistent ﬁndings have
emerged linking adolescent use of pornography that depicts violence with
increased degrees of sexually aggressive behavior.
The literature does indicate some correlation between adolescents’ use
of pornography and self-concept. Girls report feeling physically inferior to
the women they view in pornographic material, while boys fear they may
not be as virile or able to perform as the men in these media. Adolescents
also report that their use of pornography decreased as their self-conﬁdence
and social development increase. Additionally, research suggests that ado-
lescents who use pornography, especially that found on the Internet, have
lower degrees of social integration, increases in conduct problems, higher
levels of delinquent behavior, higher incidence of depressive symptoms, and
decreased emotional bonding with caregivers.
Research Review: Impact of Internet Pornography on Adolescents 117
Research in the domain of neuroimaging, neuroscience, and neuropsy-
chology can only offer speculation regarding the impact of adolescent use
of pornography at this time. However, based on hypotheses deduced from
other populations, pornography use among vulnerable groups appears con-
traindicated. The long term impact of these effects and trends requires further
investigation. Given that children and adolescents are widely considered the
most vulnerable audiences to sexually explicit material, and that the rate,
manner and type of exposure is categorically different from that of pre-
Internet generations, this is certain to be a relevant area of study for some
time. The effects of Internet pornography use might be better described
through pertinent, vigorous research. Such research will assist parents, edu-
cators, policy makers, health professionals and law enforcement in fostering
and supporting the healthy development of youth, while minimizing the risk
potential for negative effects related to Internet pornography.
