Sexual arousal and the pursuit of attractive mating opportunities

From an evolutionary perspective, sexual arousal may function, in part, to motivate the pursuit of attractive mating opportunities. We designed a study to test three aspects of this hypothesis. Several hundred heterosexual men and women completed a short survey about sexual arousal in response to a casual sex mating opportunity. We replicated previous research documenting that men report greater sexual arousal than women in response to a short-term mating opportunity. We argue that it is unlikely that a “downplaying of alternatives” psychology evolved, whereby mated individuals rate opposite-sex targets as less attractive than do unmated individuals, but instead that men and women have a relationship-seeking psychology, motivating them to pursue attractive mating opportunities. The results supported this relationship-seeking psychology rather than a downplaying alternatives psychology. Discussion addresses directions for future research on the motivational properties of sexual arousal.     

Adolescent Sexual Assault Victims and the Legal System: Building Community Relationships to Improve Prosecution Rates

Adolescents are at high risk for sexual assault, but few of these crimes are reported to the police and prosecuted by the criminal justice system. To address this problem, communities throughout the United States have implemented multidisciplinary interventions to improve post-assault care for victims and increase prosecution rates. The two most commonly implemented interventions are Sexual Assault Nurse Examiner (SANE) Programs and Sexual Assault Response Teams (SARTs). The purpose of this study was to determine whether community-level context (i.e., stakeholder engagement and collaboration) was predictive of adolescent legal case outcomes, after accounting for "standard" factors that affect prosecution success (i.e., victim, assault, and evidence characteristics). Overall, 40% of the adolescent cases from these two SANE-SART programs (over a 10-year period) were successfully prosecuted. Cases were more likely to be prosecuted for younger victims, those with disabilities, those who knew their offenders, and instances in which the rape evidence collection kit was submitted by police for analysis. After accounting for these influences, multi-level modeling results revealed that in one site decreased allocation of community resources to adolescent sexual assault cases had a significant negative effect on prosecution case outcomes. Results are explained in terms of Wolff's (Am J Community Psychol 29:173-191, 2001) concept of "over-coalitioned" communities and Kelly's (1968) ecological principles.     

Intimate partner violence in the military: Treatment considerations

While considerable research has examined the prevalence of IPV in civilian couples, much less information is available on married or cohabitating couples in which one or both parents are active duty soldiers or veterans of foreign wars. In this review, we explore various aspects of the partner violence phenomena among military personnel (i.e., active duty and veterans) and their implications for intervention. We highlight (a) the scope of the problem, (b) discuss domestic violence as defined by the Department of Defense (DoD), (c) list prevalence rates of IPV among military families, (d) identify correlates of IPV, and (e) discuss treatment options for providers working with these couples. We also discuss the barriers to intervention and their implications for victims, perpetrators, and providers. Conclusions and recommendations for future research directions are also briefly discussed.     

An assessment of body appreciation and its relationship to sexual function in women

Objectification theory posits internalization of an observer's gaze may negatively impact women's feelings about their bodies, which may subsequently affect their sexual function. Subjective body image and body size (i.e., body mass index [BMI]) have mixed relationships to women's sexuality, but assessment of positive body image as a sign of resistance to objectification has not been researched. This study explored relations between body appreciation and sexual function in women and assessed whether body size impacted this relationship. Cross-sectional data were collected online from 247 women, ages 18 to 58. Body appreciation scores were modestly negatively correlated with BMI, while BMI was not related to sexual function scores. After controlling for sexual orientation, partner status, and age, body appreciation predicted the arousal, orgasm, and satisfaction aspects of sexual function. Practitioners’ encouragement of body appreciation may improve sexual function in a way that encouraging a reduction in body size may not.     

Posttraumatic stress disorder: A sensitization reaction

This article discusses past research bearing on the question of the etiology of Posttraumatic Stress Disorder (PTSD). It argues that PTSD can be adequately accounted for by a process of emotional sensitization and that this is a more parsimonious explanation than the two-factor learning theory of Mowrer, now postulated by several writers. In brief, the etiology and subsequent development of PTSD is viewed as the result of the sensitization of fear/anxiety which is linked to a variety of to be conditional stimuli by both backward and forward association: these become conditional stimuli (CSi) once paired with the instigating circumstances. It is furthermore assumed that PTSD will not occur in the absence of a genetic susceptibility that may vary from zero to absolute certainty. Thus far, our evidence is limited to a sensitivity to loud sounds, but it is highly probable that touch and other sensory systems are involved (not necessarily in parallel). The fact that abuse often leads to behavioral disorders, including sexually seductive behaviors in children sexually abused, requires a recognition that emotional reactions other than fear may be sensitized. Fear in combination with pleasure or pleasure alone coupled with a loss of self-esteem may explain these acting-out behaviors.     

The interaction of state and trait aspects of self-focused attention affects genital, but not subjective, sexual arousal in sexually functional women

In this study we investigated the effects of state and trait aspects of self-focused attention on genital and subjective sexual arousal of sexually functional, healthy women during presentation of audiovisual erotic stimuli. Psychophysiological sexual response was measured as vaginal pulse amplitude using a vaginal photoplethysmograph. Experiential aspects of sexual arousal were measured both during stimulus presentation and retrospectively after stimulus offset. Trait level of sexual self-focus was measured with the Sexual Self-Consciousness Scale. State self-focus was induced by switching on a TV camera that pointed at the participant's face and upper torso. A manipulation check revealed that both groups experienced equally elevated levels of self-focused attention of their physical appearance. Induction of state self-focus per se did not affect genital responses, but an interaction effect of self-focus and participants' level of trait sexual self-focus was revealed. Compared with women with low scores on this trait, women with high scores exhibited smaller genital responses when state self-focus was induced. Both groups did not differ when no self-focus was induced. Increase of state self-focus did not affect subjective sexual arousal, but participants with a high level of trait sexual self-focus reported stronger subjective arousal, compared with those with low trait level. The results were discussed with reference to previous work in this field. Some implications for treatment of sexual arousal disorder were discussed.     

Is aversion to incest psychologically privileged? When sex and sociosexuality do not predict sexual willingness

As human possess powerful incest-avoidance mechanisms (which likely evolved due to the high costs of inbreeding), reactions to incestuous sexual encounters may be psychologically distinct from reactions to non-incestuous (but still non-normative) sexual encounters. Accordingly, variables such as sex and sociosexuality that normally predict openness to sexual encounters in other situations (i.e., men and sociosexually unrestricted people tend to be more sexually willing) may not do so – or do so only weakly – in incestuous situations. In Study 1, sociosexuality predicted negative judgments of non-incestuous (but still normatively proscribed) sexual acts, but not judgments of incestuous sexual acts. In Study 2, sociosexuality predicted negative reactions to imagined sex with biologically unrelated (but still normatively unusual) partners, but not reactions to imagined sex with related partners (this effect was limited to women); also, men reacted less negatively than women to imagined sex with unrelated partners, but men and women reacted equally negatively to imagined sex with related partners (the latter effect was limited to sociosexually restricted men).     

Ten years of longitudinal research on U.S. adolescent sexual behavior: Developmental correlates of sexual intercourse,and the importance of age,gender and ethnic background

We integrated findings from 35 recent, longitudinal studies of the onset of heterosexual intercourse. Correlates of adolescent sexual intercourse onset, whether in early (before age 16) or middle (ages 16–18) adolescence, included living with other than two biological parents, being less monitored by parents, having more advanced physical maturity and more involvement in dating behavior, and having more permissive attitudes toward sex. When studies were organized by age of participants, the onset of intercourse was more strongly associated with alcohol use, delinquency, school problems and (for girls) depressive symptoms in Early studies (sexual intercourse by age 15 or before only) than was found in studies classified as Middle (assessment of sexual intercourse up to age 18) or Late (knowledge of those who delayed until after age 18). Although more research is needed, additional factors were associated with delaying first sexual intercourse until after age 18, including religious attitudes and anxiety, with some factors more relevant for girls and some more applicable to boys. In total, the evidence suggests there are many similarities, but also some important differences, in the correlates associated with early versus middle versus later onset of sexual intercourse. This seems to signify more than one pathway (set of distal and proximal correlates) associated with sexual behavior during adolescence that should be tested in future research. Throughout the review, we highlight differences in the correlates of girls’ versus boys’ sexual intercourse and how race/ethnicity moderates associations. These gender and racial/ethnic differences were found largely in analyses of family processes, school and religion, and parent education. We end by summarizing several priority areas for future research.     

Slurs, Snubs, and Queer Jokes: Incidence and Impact of Heterosexist Harassment in Academia

Previous research has suggested that overt hostility against sexual minorities is associated with decrements in their well-being. However, subtler forms of heterosexism and their potential effects have been overlooked, heterosexuals have not been asked how they fare in a heterosexist environment, and no research has examined whether women and men might respond differently to heterosexism. Data from 3,128 northwestern US university students (representing all sexual orientations) address these gaps. Approximately 40% reported experiences of heterosexist harassment (HH) in the past year, and those who encountered both ambient and personal HH reported worse psychological and academic well-being than those who encountered no HH. Similar patterns of findings held for sexual minorities and heterosexuals, and for women and men. This paper is based on a presentation given at the American Psychological Association Convention in Toronto, Ontario in August 2003.
