Abstract
Mobile device use has become increasingly prevalent, yet its impact on infant develop-
ment remains largely unknown. When parents use mobile devices in front of infants,
the parent is physically present but most likely distracted and unresponsive. Research
using the classic Still Face Paradigm (SFP) suggests that parental withdrawal and unre-
sponsivenessmayhavenegativeconsequencesforchildren’ssocial-emotionaldevel-
opment. In the present study, 50 infants aged 7.20 to 23.60 months (M = 15.40, SD =
4.74) and their mothers completed a modified SFP. The SFP consisted of three phases:
free play (FP; parent and infant play and interact), still face (SF; parent withdraws at-
tention and becomes unresponsive), and reunion (RU; parent resumes normal interac-
tion). The modified SFP incorporated mobile device use in the SF phase. Parents
reported on their typical mobile device use and infant temperament. Consistent with
the standard SFP, infants showed more negative affect and less positive affect during
SF versus FP. Infants also showed more toy engagement and more engagement with
mother during FP versus SF and RU. Infants showed the most social bids during SF and
more room exploration in SF than RU. More frequent reported mobile device use was
associated with less room exploration and positive affect during SF, and less recovery
(i.e., engagement with mother, room exploration positive affect) during RU, even when
controlling for individual differences in temperament. Findings suggest that the SFP
represents a promising theoretical framework for understanding the impact of par-
ent’s mobile device use on infant social-emotional functioning and parent–infant
interactions.
RESEARCH HIGHLIGHTS
• The traditional Still Face Paradigm (SFP) was modified to include
mobile device use, mimicking typical disruptions in parent–infant
interactions that may occur in daily life.
• Patterns of child behavior during the modified SFP mirrored those
of the traditional version, with infants showing the most distress
when mothers were disengaged.
• Greater habitual self-reported maternal mobile device use was as-
sociated with less infant recovery upon reunion.
• Findings provide support for the use of this modified paradigm as a
frameworkforunderstandingtheimpactofparent’smobiledevice
use on infant social-emotional functioning and parent–infant
interactions.
1 | INTRODUCTION
The exponential increase in mobile device use has transformed not
only how we communicate remotely, but also how we engage in

face- to- face interactions. Greater mobile device use in adults has
been associated with mental health problems, including anxiety (Reid
& Reid, 2007; Sapacz, Rockman, & Clark, 2016). However, little is
knownabouttheimpactofdeviceuseonparent–infantinteractions.
Frequent use of mobile devices during these interactions may de-
crease the quality of the social exchange by limiting opportunities for
the in- the- moment emotional feedback essential for emotion regula-
tion development (Field, 1994).
Infant behavior during dyadic interactions can be assessed using
the Still Face Paradigm (SFP; Braungart- Rieker et al., 2014; Fuertes,
Santos, Beeghly, & Tronick, 2006; Montirosso, Casini et al., 2015;
Montirosso, Provenzi et al., 2015; Provenzi, Borgatti, Menozzi, &
Montirosso,2015; Tronick,Als,Adamson, Wise, & Brazelton, 1978),
a classic laboratory behavioral task that examines infant responses to
social cues by a parent, consisting of three phases: Free Play (FP), Still
Face (SF), and Reunion (RU). The FP phase serves as a baseline for par-
ent–infantplay,whiletheSFphasedisruptsthisinteractionbymaking
the parent cease initiating or responding to social cues, while main-
taining eye gaze. Infant behavior during the SF phase is characterized
by decreased positive affect and gaze, and increased negative affect
(Mesman,vanIJzendoorn,&Bakermans-Kranenburg,2009).Maternal
regulation of infant emotion is absent during this phase, and when
bids for emotional reciprocation are not returned, the infant tends to
respond with distress and confusion (Montirosso, Casini et al., 2015;
Montirosso, Provenzi et al., 2015; Provenzi et al., 2015; Trevarthen,
1977). Finally, the RU phase provides an opportunity to repair subse-
quent mismatches in dyadic behavior by resuming interactive play. The
current study created a modified version of the classic SFP by employ-
ing a novel SF phase that introduced an ecologically valid mechanism
(mobile device use) that in effect may typically make parents unavail-
able to infants in daily life.
Infant behavior during the SFP is related to broader patterns of emo-
tional and social well- being, with greater positive affect and social bids
during the SF phase predicting secure attachment (Braungart- Rieker
etal., 2014; Fuertesetal., 2006; Kiser, Bates, Maslin, & Bayles, 1986;
Tronick, Ricks, & Cohn, 1982). In addition, infant individual differences
are related to their behavior during the SFP. For example, infants with
greater parent- rated temperamental negative affectivity showed re-
duced self- comforting during SF, potentially blunting regulation and re-
covery during RU (Braungart- Rieker, Garwood, Powers, & Notaro, 1998;
Mesman etal., 2009).In addition, Rothbart,Ziaie, and O’Boyle (1992)
found that self- regulatory behaviors during the task were related to in-
fant temperament. For example, activity level was negatively related to
oral self- soothing, fear scores were positively related to inhibited reach
and negatively related to approach, and attention disengagement was
negatively related to distress and positively related to positive affect.
Alargebodyofresearchhasalsoestablished theSFPas anana-
log for dyadic interactions between a depressed mother and her child
(Field, 1994; Field et al., 2007). In one study, the SF phase elicited less
distress in infants of depressed mothers compared to controls (Field
et al., 2007), potentially since this lack of emotional responsiveness
tends to be more habitual in day- to- day interactions for infants of de-
pressed mothers.
Several studies have modified components of the classic SFP.
In one study, modifications included mothers wearing masks while
maintaining eye contact and vocal interactions with their children, or
drinking from a bottle while maintaining eye contact and a neutral,
unresponsive face. Infants only displayed negative affect in response
to the traditional still face but not to the modified versions (Legerstee
& Markova, 2007), suggesting that infants may have interpreted the
mothers’unresponsivenessdifferentlywhentiedtoa novelbehavior.
In another study using a modified SF phase in which mothers played
with another infant, 6- month- old infants responded with heightened
sadness and interest that exceeded that of the traditional SFP (Hart,
Carrington,Tronick,&Carroll,2004).Athirdstudymodifiedthetradi-
tional SFP for use with toddlers by using the same three phases, but
placingtheminthe middleofalongermother–childfreeplaysession
(Weinberg, Beeghly, Olson, & Tronick, 2008). Toddlers showed similar
response patterns as infants, including the classic still face effect, but
also exhibited a wider array of responses, including vocalizations that
expressedaneffortto understandthe reasonforthemother’sunre-
sponsiveness. Thus, Weinberg and colleagues (2008) demonstrated
that the SFP can be used to examine behavior across a wider age range
than previously examined.
Similar to the key components of the classic SFP, parent mobile de-
vice use in front of infants causes the parents to be physically present
but putatively distracted and unresponsive. While mobile device use
is pervasive, only two studies to date have investigated how engage-
mentwith devicesmayinterferewithparent–childinteractions.One
study found that during a structured interaction task, maternal mobile
deviceusewas commonandassociatedwith fewermother–child in-
teractions (Radesky et al., 2015). In a descriptive observational study,
Radesky and colleagues (2014) found that parents who were deeply
absorbed in mobile device use during meal times tended to respond to
child bids for attention in insensitive or aggressive ways. However, no
study to date has examined how infant social and emotional behavior
is influenced by parental device use during dyadic interactions.
The first aim of the current study is to establish whether a mod-
ified SFP that incorporates maternal mobile device use could serve
as an analog to the original SFP, probing the impact of distracted or
unresponsive parents on child socioemotional behavior. Specifically,
given that mobile device use may mimic the social and emotional dis-
engagement present in the classic SFP, we predict that there will be
greater negative affect, and less positive affect, during the SF phase,
compared to the FPand RU phases. Also, we predict that dyadic
interaction will resume upon the RU phase, with infants showing
more engagement with mother in the RU phase compared to the SF
phase. Second, we aim to examine whether or not maternal device
use habits predict individual differences in infant behavior during
the SFP. Specifically, based on research using the SFP with infants
and depressed mothers (Field et al., 2007), we hypothesize that
habitual device use will be associated with less negative responses
from infants in the SF phase. That is, mothers who frequently use
devices, particularly in front of their family and infants, may habit-
ually show a lack of emotional responsiveness during interactions,
making their infant more accustomed to such disruptions and thus

eliciting less distress. Third, based on previous studies suggesting
that temperament may make infants more sensitive to the still face
disruption (Braungart- Rieker et al., 1998), we predicted that infants
high in negative affect would show greater disruption during the SF
and less re- engagement during the RU.
2 | METHOD
2.1 | Participants
Fifty infants (25 female) ages 7.20 to 23.60 months (M = 15.40, SD
= 4.74)1 participated in a modified SFP with their mothers. Forty-
five(90.0%)parents reported their infant’s ethnicity as White/Non-
Hispanic, three (6.0 %) reported Hispanic, three (6.0 %) reported
Asian/Pacific Islander, one (2.0 %) reported African-American, and
one(2.0%)reported NativeAmerican.Allinfantswerebornwithin2
weeks of their due date, reported no major health complications, and
were within normal birthweight ranges (M = 7.53 lb, SD = 1.14).
2.2 | Materials
2.2.1 | The modified SFP
Infants and their mothers participated in a modified SFP (Tronick
et al., 1978), which consisted of three phases: a free play phase (FP; 5
minutes), during which mother and infant interacted as they naturally
would during play time; a still face phase (SF; 2 minutes), during which
an alarm signaled the mother to pick up a mobile device (iPod touch),
interact only with the device, withdraw attention from their infant, be-
come unresponsive, and allow their infant to play on their own; and a
reunion phase (RU; 1 minute; signaled by a knock on a window), during
which the mothers stopped using the device and resumed interacting
with their infant as they did during FP. This modified SFP altered the
protocol of the original SFP by instructing mothers to use a mobile de-
vice during SF, allowing infants to move around freely instead of con-
fining them to a high chair, and allowing infants to have access to toys
throughout the task. We also varied the durations for each of the three
SFPphases.AkeydifferencebetweenthemodifiedSFPandtheorigi-
nal SFP is that we did not require mothers to maintain eye contact while
avoiding any communication with infants, which was a feature present
in the original SFP. These modifications were intended to increase the
ecological validity of the SFP by including features that more closely
mimicked scenarios that may arise in everyday life.
2.2.2 | Behavioral coding
The SFP was video- recorded and scored by three reliable raters.
Reliability was computed across 20% of participants using Cohen’s
kappa, and ranged from .71 to .98 (M = .85, SD = .03). Presence or ab-
senceofeachbehavior(0,1)wascodedin15secondepochs.Average
scores were computed (number of epochs each behavior was per-
formed divided by total number of behaviors) for each phase (FP, SF,
RU) to account for individual differences between children who showed
generally higher and lower behavioral frequencies overall. Behaviors
performed by at least 25% of infants in at least one phase were selected
for analyses (negative affect, positive affect, toy engagement, engage-
ment with mother, social bid, room exploration; Table 1).2

infantswhose parentscompletedthe infant (IBQ)ortoddler (TBAQ)
version of the questionnaire (ps > .10). Subscales represented on both
versions of the questionnaire that captured characteristics relevant to
behavior during the SFP were examined: activity level, approach/in-
terest, attentional control (duration and orienting from IBQ- R and ap-
propriateattentional allocationfromTBAQ),and negative affectivity
(higher order subscale consisting of fear, sadness, distress to limitation,
and falling reactivity).
2.3 | Procedure
This study was approved by the institutional review board of the
Pennsylvania State University. Parents and infants participated in
either one (2.5 hour duration) or two (to prevent infant fatigue; 1.5
hour duration) lab visits, as part of a larger study. Following informed
consent, parents completed questionnaires reporting their infant’s
temperament and demographics. Participants then completed the
modified SFP task with their infant (approximately 8 minutes). The
modified SFP task was video- recorded to allow for observation of in-
fant behaviors. Participants were compensated with $50 and infants
received a T- shirt with the lab logo.
3 | RESULTS
3.1 | Descriptive statistics
Descriptive statistics for infant behavior during the SFP, maternal de-
viceuse,andinfanttemperamentarepresentedinTables2–4.
Pearson correlations were conducted to examine associations
between infant age and sex relative to other study variables. Infant
age was normally distributed, and there were an even number of
males and females in the sample. There were no differences be-
tween males and females in child temperament (ps > .10), maternal
mobile device use habits (ps > .10), or infant behaviors during the
SFP (ps > .10). Older infants showed more engagement with mother
during FP (r = .46, p = .001), and infant age was positively correlated
with attentional control (r = .34, p = .02) and approach/interest (r =
.42, p = .003). Infant age was not significantly correlated with ma-
ternal mobile device use (ps>.10).Althoughtherewereonlylimited
relations between infant age and other measures, due to the wide
age range of the sample, age was included as a covariate in subse-
quent analyses to control for the potential influence of developmen-
tal stage on observed behaviors (e.g., greater mobility, verbal skills
in older infants).
3.2 | Analytic plan
First, as a manipulation check, we examined within- subject differ-
ences in behaviors across the three phases of the SFP to confirm that
the parameters of the task elicited varying levels of child behaviors.
Second, a series of regressions were conducted to examine the main
research question regarding the relationship between maternal device
use and infant behavior in the SFP.

3.3 | Infant behavior during still face paradigm
To examine differences across the phases of the SFP, repeated-
measures ANCOVAs were conducted separately for each behavior
(negative affect, positive affect, toy engagement, engagement with
mother, social bids, room exploration) with age in months as a co-
variate, and Phase (FP, SF, RU) as a within- subjects factor (Figure 1).
Bonferroni correction was used to control for multiple comparisons in
post- hoc paired- samples t tests (adjusted p = .017).
Affect: Mirroring the effects of the traditional SFP, infants
showed more negative affect during SF versus FP, [t(49) = 2.98, p =
.004; F(2, 96) = 5.67, p = .005, ƞp
2=.11].Incontrast,infantsshowed
less positive affect during SF versus FP [t(49)=−7.14,p<.001]and
RU [t(49)= −3.85,p < . 001; F(2, 96) = 23.11, p < .001, ƞp
2= .33].
Positive affect was also greater during FP in comparison to RU [t(49)
= 2.64, p=.011].
Toy engagement: Infants showed more toy engagement in FP com pared
to SF [t(49) = 3.37, p= .001]andRU[t(49) = 2.16, p < .001; F(2, 96) =
11.25, p < .001, ƞp
2=.19].
Social behaviors: Infants also showed less engagement with mother
during SF compared to FP [t(49)=−17.64,p< .001]and RU[t(49) =
−11.37,p < .001; F(2, 96) = 117.83, p < .001, ƞp
2= .71]. Social bids
were used more in SF compared to FP [t(49) = 6.76, p<.001]andRU
[t(49) = 5.51, p < .001; F(2, 98) = 37.70, p < .001, ƞp
2=.44].
Exploration: Finally, infants explored the room less in RU compared
to SF [t(49)=−3.50,p = .001; F(2, 98) = 6.89, p = .002, ƞp
2=.13].
3.4 | Infant temperament and behavior during still
face paradigm
To identify covariates for regression analyses, infant temperament
was examined in relation to mobile device use and child behavior dur-
ing the SFP. Pearson correlations revealed that infants with greater
parent- reported negative affectivity showed less engagement with
mother during FP (r=−.31,p = .03), and less room exploration during
RU (r = −.30, p = .03). Infants with greater parent- reported activity
level expressed more negative affect during SF (r = .29, p = .04). Infants
with greater approach/interest engaged in more room exploration
during SF (r = .32, p = .03).
3.5 | Maternal mobile device use and infant behavior
during still face paradigm
Associationsbetween self-reportof maternal mobiledeviceuse and
behavior during the SFP were examined using linear regressions as
follows: 1st step = age, sex, and infant temperament variables (nega-
tive affectivity, activity level, approach/interest); 2nd step = maternal
device use (separately for mobile device use variable: overall habitual
use,useinfrontoffamily,useinfrontofinfant);DV=infantbehavior
during SFP, separately for each phase. Infant temperamental variables
were included as covariates since they correlated with infant behavior.
The Benjamini- Hochberg correction (Benjamini & Hochberg, 1995)
was applied to correct for multiple comparisons for each phase.3
This procedure, which involves ranking p- values and accounts for the
number of tests conducted, was applied separately to each family of
regressions (i.e., separately for each SFP phase), since this correction
approach assumes independence of samples. All p-values reported
below are raw, and were significant using a false discovery rate crite-
rion of 0.25 which is recommended for research questions that are a
first, relatively exploratory step (Benjamini & Hochberg, 1995). Based
on these parameters, raw p- values less than approximately .085 were
considered significant.

4 | DISCUSSION
Since infants tend to respond to maternal unresponsiveness during
the SF phase with distress (Trevarthen, 1977), the SF phase is char-
acterized by a decrease in positive affect and an increase in negative
affect (Mesman et al., 2009). Consistent with the extant literature,
the modified SFP using a mobile device in the current study produced
robust differential patterns of infant behavior between the three
phases. Infants expressed increased negative affect in the SF versus
FP, as well as decreased positive affect and engagement with mother
in SF versus both FP and RU. Infants also increased social bids dur-
ingtheSFinanattempttoobtain theircaregiver’s attention.Infants
displayed more toy engagement during FP versus the other phases,
likely due to the fact that infants were adjusting to the new environ-
ment and parents aided in toy engagement when they were available
to interact, whereas during RU infants were preoccupied with re-
engaging with the parent and they lacked scaffolding for play during
SF. Finally, infants explored the room less in RU compared to SF, pos-
sibly because they were more focused on reuniting with their mother
following the SF phase. In fact, as predicted, infant engagement with
mother increased significantly between the SF and RU phases. Two-
way engagement was greater in FP and RU when the rules of the task
allowed for it, whereas social bids were greater when the parent was
unavailable during SF. These observed patterns illustrate that the
modified SFP may act as a potentially analogous paradigm to the origi-
nal SFP and can be used to understand the implications of maternal
device use on infant social- emotional functioning.
Results of the current study also indicated that individual differ-
ences in infant temperament contribute to behavior during the SFP
phases. Infants with higher parent- reported temperamental negative
affectivity engaged less with their caregiver during FP. During RU, in-
fants with higher negative affectivity displayed less room exploration,
indicating less recovery. This is consistent with findings that infants
high in negative affectivity showed less emotion regulation during SF,
blunting recovery during RU (Braungart- Rieker et al., 1998; Mesman
et al., 2009). During SF, infants with greater activity level scores
showed more negative affect. It is possible that it is more challenging
for more active infants to deal with their nonresponsive parent, result-
ing in increased negative affect. Finally, infants with greater approach/
interest scores showed more room exploration during SF. Increased
approach and interest scores may be related to decreased fear (Buss,
2011; Rothbart et al., 1992) and increased curiosity about the environ-
ment, resulting in increased room exploration.

and emotional unavailability may decrease the quality of the social
exchange (Field, 1994), no study has examined the effect of maternal
device use on infant behavior and emotion regulation. The results of
the current study suggest that greater maternal mobile use is associ-
ated with behavior patterns across the SFP phases, even when infant
temperamental traits are taken into account. Contrary to predictions,
infants of mothers who frequently used devices did not show less neg-
ative affect, or more positive affect, during the SF phase. We did note
decreased room exploration during SF and RU as a function of greater
habitual use, indicating that these infants were not unaffected by the
disruption. These findings may suggest that parental habitual device
usemaybeassociatedwithan infant’sabilityto adjusttotheir envi-
ronment and highlight the need for future research in this area.
Importantly, during RU, greater habitual device use was associated
with less positive affect, less engagement with mother, and less room
exploration. The RU phase is crucial in that it provides an opportunity
for the parent and infant to reconnect. However, the current study
showed that with greater habitual device use, the reunion between
mother and infant was not as successful. Consistent with previous re-
search showing that greater parental mobile device use was related to
less interaction with children (Radesky et al., 2015), and insensitive or
aggressive parent responses to social bids (Radesky et al., 2014), the
current findings suggest that frequent habitual device use may reduce
the successful repair of interactions following disruptions. These results
highlight the importance of research surrounding parental device use
and its impact on both infant emotional regulation development and the
qualityof social exchange in parent–infantinteractions. The modified
SFP represents a promising theoretical framework for this research.
Although the results from the current study confirm the find-
ings that parental mobile device use is associated with infant social-
emotionalfunctioningandparent–infantinteractions,somelimitations
should be noted. First, the age range included in the current study
was relatively wide, encompassing developmental stages with vary-
ing levels ofmobility, language ability, and understanding ofothers’
intentions. For these reasons, age was included as a covariate in all
main analyses. Age did not significantlyalter the pattern of results
when examining either infant behaviors across stages or relations be-
tweenmaternaldeviceuseandinfantbehavior.Althoughthecurrent
findings represent a crucial starting point and previous studies have
illustrated that the SFP can be used across a wide age range (Weinberg
et al., 2008), future studies must investigate smaller age ranges and/
or track changes longitudinally across early childhood to more con-
cretely understand when and how maternal device use impacts social-
emotionaldevelopment.Also,thecurrentstudylackeda comparison
group or comparison condition exposed to the classic SFP at the same
age. Future studies should aim to address this gap to establish if the
two versions elicit similar patterns of behavior in the same child.
In addition, contrary to the classic SFP, in the modified SFP with
a mobile device, toys were freely available, infant mobility was not
restricted, and mothers were not instructed to maintain eye contact
during SF. Importantly, these variations included in the modified SFP
more closely resemble real-life parent–child interactions involving
disruptions in social- emotional communication, thus increasing the
ecological validity of this paradigm. Due to these differences, the cur-
rent SF may have elicited overall lower levels of negative affect versus
other behaviors as compared to the classic SF (Braungart- Rieker et al.,
2014; Fuertes et al., 2006; Montirosso, Casini et al., 2015; Montirosso,
Provenzi et al., 2015; Provenzi et al., 2015). This difference in negative
affect frequency could also be due to differences in coding methods
used (e.g., 30 second epochs versus second- by- second microanalysis).
It also may be that infants are more accustomed to disruptions due to
mobile device use and thus were not as distressed as they would be by
the classic SFP. These subtle, low- level expressions of negative affect
might be common among children whose parents habitually and fre-
quently use mobile devices, and future research should examine their
function, such as serving to re- engage the parent or express distress.

greater than 5 hours per day for three contexts: general device use
frequency, use in front of family, and use in front of their infant. Future
research should track device use in real time or complete in- home be-
havioral observations to observe how often parents use their device
and how the infant reacts. This would provide a better understanding
of how parent device use and how familiarity with a device may impact
aninfant’sresponses.Itwouldalsobebeneficialtotrackinfantsocial-
emotional functioning over time to determine whether device use has
a long- term impact on emotion regulation development.
Finally, it is important to note that the durations of the three
phases were altered from the original SFP. Similar to previous studies
(Weinberg et al., 2008), an extended free play phase was included to
allow dyads enough time to adjust to the room in which they had the
freedom to move at will, in contrast to the classic SFP. However, the
most notable shortcoming of the current SFP design was that the re-
union phase was only 1 minute long. Despite this short time- period,
infants exhibited patterns of behavior suggesting dyadic interaction
repair (e.g., increase in engagement with mother), as well as significant
individual differences in recovery behaviors, which related to mobile
device use habits. This suggests that, while this short RU phase may
not be ideal, it was sufficient to detect notable patterns of infant be-
havior and lays the groundwork for subsequent investigations. Future
studies should extend this phase to observe recovery over a longer pe-
riod, and track individual differences in recovery trajectories in relation
to patterns of daily device use.
The modified SFP used in the current study may represent a fruitful
methodforexaminingthe useofdigitaldevices inparent–child rela-
tionships in a controlled, yet ecologically valid manner. Taken together,
results suggest that parental device use influences the quality of par-
ent–infantinteractions,andhighlighttheneedforcontinuedresearch
on the role of technology in infant social- emotional development.
ENDNOTES
1 The current sample was a subsample taken from a larger study examin-
ing broader patterns of socioemotional functioning in the first 2 years
of life (LoBue, Buss, Taber- Thomas, & Pérez- Edgar, 2017; Morales et al.,
2017;Pérez-Edgar,Morales,LoBue,Taber-Thomas,Allen,Brown,&Buss,
in press).
2 The distributions for some of the observed behaviors were significantly
positively or negatively skewed. However, these skewed behaviors
would be expected to be used either extremely frequently or infre-
quently due to the nature of the paradigm (e.g., task parameters would
not be expected to elicit social bids from children during free play
or reunion). These skewed behaviors were included in the repeated-
measures analyses only, in order to track differences in behavior fre-
quency across the three phases.
