This study examines the impact of a visual representation of a secure base (i.e. a secure base prime) on attenuating experimentally produced anger and anxiety. Specifically, we examined the assuaging of negative emotions through exposure to an image of a mother-infant embrace or a heterosexual couple embracing. Subjects seated at a computer terminal rated their affect (Pre Affect) using the Affect Adjective Checklist (AAC) then listened to two sets of intense two person conflicts. After the first conflict exposure they rated affect again (Post 1 AAC). Following the second exposure they saw a blank screen (control condition), pictures of everyday objects (distraction condition) or a photo of two people embracing (Secure Base Prime condition). They then reported emotions using the Post 2 AAC. Compared to either control or distraction subjects, Secure Base Prime (SBP) subjects reported significantly less anger and anxiety. These results were then replicated using an internet sample with control, SBP and two new controls: Smiling Man (to control for expression of positive affect) and Cold Mother (an unsmiling mother with infant). The SBP amelioration of anger and anxiety was replicated with the internet sample. No control groups produced this effect, which was generated only by a combination of positive affect in a physically embracing dyad. The results are discussed in terms of attachment theory and research on spreading activation.

We explored themes related to sexual desire (lust) and romantic desire (love) in the lyrics of popular music over the past 40 years. We examined whether there have been changes in the prevalence of lust and love themes and changes in how these themes inter-relate in music lyrics over time. The study sample consisted of the top 40 songs of Billboard Year End Hot 100 single songs for every 5 years from 1971 to 2011 (N = 360). There was a linear decrease over time in the proportion of songs with a love theme and in the proportion of songs with a combination of lust and love themes. In contrast, there was a significant increase in the proportion of songs with a theme focusing on lust in the absence of love. Themes of lust in the absence of love were especially prevalent in hip-hop/rap music, although music genre did not account for the changing themes over time. These shifts in themes found in popular music may both influence cultural norms and reflect a cultural shift toward acceptance of sexuality outside of love relationships.

Although masturbation is one of the most common sexual behaviours, ambivalent cultural attitudes toward this behaviour persist. We examined how masturbation is portrayed in popular North American movies as a means of documenting current social norms regarding masturbation. The sample consisted of 44 movies from 2005 to 2010 in which a target character was shown masturbating. Coders assessed several aspects of these portrayals, including the positivity of the scene, initiating factors (e.g., watching pornography, boredom), and the outcome of the masturbation (e.g., interruption, sexual relief). As well, we explored potential gender differences in these portrayals. Masturbation was generally shown in a somewhat negative light, especially when engaged in by male characters. It was portrayed as a substitute for preferred partnered sex and as often leading to negative outcomes such as being caught or interrupted. The results suggest that movie portrayals of masturbation may reinforce misconceptions about masturbation and its outcomes.

Polyamory is characterized by simultaneous consensual romantic relationships with multiple partners. Polyamory allows individuals to fulfill their relationship needs with multiple romantic partners, yet researchers have not identified how having needs met in one romantic relationship may be related to relationship outcomes in a concurrent relationship. Polyamorous individuals (N=1,093) completed online measures of need fulfillment, relationship satisfaction, and commitment for two concurrent romantic relationships. Participants reported high levels of need fulfillment and satisfaction in both relationships. Need fulfillment with one partner negatively predicted approximately 1% of the variance in relationship satisfaction with the other partner; however, there was no association between need fulfillment with one partner and commitment to the other. Generally, the findings suggest that polyamorous relationships are relatively independent of one another. This study provides initial evidence that polyamory may be a viable and fulfilling alternative way of conducting intimate relationships.

Partners in close relationships inevitably encounter situations in which their interpersonal goals are incompatible, and a disturbing number of partners resort to violence when confronted by these challenges. We present a dyadic framework for integrating theory and research on intimate partner violence based on the premise that relationships are inherently interactional. We consider the enduring characteristics of both partners (background/dispositional factors), how partners' predispositions interact over time to create an intimate relationship (the relationship context), and the particular situations in which relational patterns can give rise to violent interactions (the situational context).

We explored individuals' relationships with an assistance dog from an attachment-theory perspective. We used both inductive and deductive thematic methods to analyze semi-structured interviews with 25 participants who had lost an assistance dog to retirement or death. Analyses revealed attachment processes of safe haven, secure base, and separation anxiety. Although attachment dynamics were an important feature of these relationships, caregiving was equally important. When confronted with the loss of their dog, almost all participants experienced intense grief. Most grief responses were consistent with the loss of a caregiving relationship. Findings suggest that grief is a natural response to the loss of a beloved companion who fulfilled fundamental needs for attachment and caregiving.

Previous studies of abuse in male same-sex relationships have been limited by convenience samples and/or by incomplete assessments of partner abuse. We examined patterns of same-sex partner abuse in a random sample of 284 gay and bisexual men. Respondents reported on perpetration and receipt of physical, psychological, and sexual abuse over multiple time frames, as well as injuries resulting from abuse. Almost all respondents reported psychological abuse, more than one-third reported physical abuse, and 10% reported having engaged in unwanted sexual activity because of partner force or threats of force. More than half of recipients of partner violence reported sustaining injury. We found strong associations between different forms of abuse, and between severity of abuse receipt and perpetration.

We investigated correlates of partner abuse in male same-sex relationships in a randomly selected community sample (N = 186). We included factors associated with abuse in heterosexual relationships, as well as factors of relevance to gay relationships. We assessed perpetration and receipt of partner abuse to examine whether variables were associated independently with abuse perpetration and/or receipt. Correlates of same-sex partner abuse were largely parallel to established correlates of heterosexual abuse. Income, education, and attachment orientation were associated with bidirectional partner abuse, and family violence and substance use were uniquely associated with victimization. Further, there were factors unique to same-sex partner abuse; HIV status and public outness were associated with bidirectional partner abuse, and internalized homophobia was uniquely associated with abuse perpetration.

The authors explored the attachment dynamics of heterosexual couples identified for male partner violence. Based on semistructured interviews, participants were assessed for attachment orientations. Based on a thematic analysis of the interviews, two strategies for regulating distance within these relationships were identified: pursuit and distancing. Partners' abusive acts often appeared to serve one of these attachment strategies. As a pursuit strategy, violence forced one partner to focus on the other, and as a distancing strategy, violence served to push a partner back when the perpetrator had been approached too closely and perceived no other means of escape or self-protection. To understand the context in which individuals acted abusively, the authors considered the interaction between the attachment orientations of both partners as they sought to regulate their emotional and physical proximity. Findings highlight the relational basis of intimate violence.
