Sexual identity trajectories among sexual-minority youths: Gender comparisons.

The present investigation explored gender differences in sexual identity development—first same-sex attractions, self-labeling, same-sex sexual contact, and disclosure—among 164 sexual-minority young adults. Based on interviews, results indicated the value of assessing gender differences in the context, timing, spacing, and sequencing of sexual identity milestones. Adolescent males had an earlier onset of all milestones except disclosure. The context for sexual identity milestones were likely to be emotionally oriented for young women and sexually oriented for young men. The gap from first same-sex attractions (8–9 years of age) to first disclosure (around 18 years) averaged 10 years for both sexes. Young women followed label-first developmental trajectories; men were more likely to pursue sex before identifying themselves as gay. In terms of achieving sexual identity milestones, gender mattered, but it was not everything.

What does sexual orientation orient? A biobehavioral model distinguishing romantic love and sexual desire

Although it is typically presumed that heterosexual individuals only fall in love with other-gender partners and gay-lesbian individuals only fall in love with same-gender partners, this is not always so. The author develops a biobehavioral model of love and desire to explain why. The model specifies that (a) the evolved processes underlying sexual desire and affectional bonding are functionally independent; (b) the processes underlying affectional bonding are not intrinsically oriented toward other-gender or same-gender partners: (c) the biobehavioral links between love and desire are bidirectional, particularly among women. These claims are supported by social-psychological, historical, and cross-cultural research on human love and sexuality as well as by evidence regarding the evolved biobehavioral mechanisms underlying mammalian mating and social bonding.

Emotion Regulation Across the Life Span: An Integrative Perspective Emphasizing Self-Regulation, Positive Affect, and Dyadic Processes

In this commentary, we build upon the papers featured in this 2-part special issue to advance an integrative perspective on emotion regulation that emphasizes the developmentally specific goal-contexts of emotional phenomena. We highlight the importance of (1) multilevel longitudinal investigations of interactions among biological, affective, cognitive, and behavioral processes with respect to emotion regulation; (2) the integration of emotion-regulation processes with self-regulatory processes across the life course; (3) the dynamic relationship between positive and negative affect and their respective influence on regulatory processes; and (4) greater consideration of the dyadic context of emotion-regulation processes. From this perspective, the optimal developmental outcome with respect to emotion regulation is not affective homeostasis, but rather a dynamic flexibility in emotional experience, the ability to pursue and prioritize different goals, and the capacity to selectively and proactively mobilize emotions and cognitions in the service of context-specific and developmentally specific goals.

Development of sexual orientation among adolescent and young adult women.

Although some research suggests that sexual orientation is a stable, early appearing trait, interviews with 89 young sexual-minority women revealed that a majority of women failed to report at least one of the following: childhood indicators of sexual orientation, stability in same-sex attractions, or awareness of same-sex attractions prior to the conscious process of sexual questioning. Lesbians were not more likely to report these experiences than bisexuals, although they reported significantly greater same-sex attractions. Consistent with studies on older cohorts, few young women reported exclusive same-sex attractions. These findings suggest that recollected consistency among prior and current behavior, ideation, and attractions are not systematically associated with sexual orientation among contemporary young women.

Emerging Perspectives on Distinctions Between Romantic Love and Sexual Desire

Although sexual desire and romantic love are often experienced in concert, they are fundamentally distinct subjective experiences with distinct neurobiological substrates. The basis for these distinctions is the evolutionary origin of each type of experience. The processes underlying sexual desire evolved in the context of sexual mating, whereas the processes underlying romantic love—or pair bonding—originally evolved in the context of infant-caregiver attachment. Consequently, not only can humans experience these feelings separately, but an individuals sexual predisposition for the same sex, the other sex, or both sexes may not circumscribe his or her capacity to fall in love with partners of either gender. Also, the role of oxytocin in both love and desire may contribute to the widely observed phenomenon that women report experiencing greater interconnections between love and desire than do men. Because most research on the neurobiological substrates of sexual desire and affectional bonding has been conducted with animals, a key priority for future research is systematic investigation of the coordinated biological, behavioral, cognitive, and emotional processes that shape experiences of love and desire in humans.

A NEW VIEW OF LESBIAN SUBTYPES: STABLE VERSUS FLUID IDENTITY TRAJECTORIES OVER AN 8-YEAR PERIOD

Research has increasingly documented that the distinction between lesbian and bisexual women is one of degree rather than kind, and some researchers have therefore argued for an end to sexual categorization altogether. To the contrary, I maintain that researchers should explore alternative criteria for sexual categorization that might allow us to discern novel and meaningful subtypes of same-sex sexuality Toward this end, I explore the usefulness of a typology that focuses on change in lesbian identification over time, using a sample of young sexual-minority women that has been observed longitudinally for a period of 8 years. Specifically, I contrast women who have maintained consistent lesbian identifications over this time period (stable lesbians) to women who have alternated between lesbian and nonlesbian labels (fluid lesbians) and women who never adopted lesbian labels (stable nonlesbians). The pattern of similarities and differences among the groups changes as a function of the specific phenomenon being assessed (e.g., sexual and emotional attractions, sexual contact, developmental histories), suggesting the value of using multiple, alternative sexual typologies as heuristics to guide future research into life span development of sexual orientation and identity.

Explaining Diversityin the Development of Same‐Sex Sexuality Among Young Women

This article summarizes findings from two ongoing studies charting the development of 167 adolescent and young adult sexual-minority women. Resultsdocument considerable variation in the quality, relative distribution, and context of womens same-sex and other-sex attractions. Furthermore, contrary to conventional wisdom, the timing of a womans first same-sex attractions is not systematically related to subsequent features of sexual identity development. Rather, the quality and context of a womansearly attractions and behavior is more important. We argue that variability in sexual-minority and heterosexual womens development is best explained by interactions between personal characteristics and environmental contexts, and we urge future studies of the sexual-minority life course to include women with same-sex attractions that do not identify as lesbian or bisexual.

Contributions of Psychophysiology to Research on Adult Attachment: Review and Recommendations:

Despite the increasing use of psychophysiological measures to investigate social and interpersonal phenomena, few studies of adult romantic attachment have taken advantage of this approach. In this article I argue for a biologically-specific, theory-based integration of psychophysiological measures into adult attachment research. This approach would help elucidate the normative psychobiological properties of the attachment system, which have received little study in humans. Specifically, it would allow researchers to test targeted hypotheses regarding affect and arousal regulation in attachment relationships. I provide a general introduction to 2 biological systems that hold particular promise for adult attachment research: the parasympathetic branch of the autonomic nervous system and the hypothalamic-pituitary-adrenocortical axis of the endocrine system. I highlight the relevance of these systems for attachment phenomena and review findings from selected social psychophysiological research. I conclude by outlining a tentative theoretical model of the psychobiology of adult attachment and identifying specific directions for future research.

Desegregating Sexuality Research: Cultural and Biological Perspectives on Gender and Desire

Abstract Scholarly investigations into male and female sexuality over the life course have long occupied two separate “camps”: One focused on the biological aspects of sexuality and one focused on the sociocultural/political aspects. This bifurcated approach has been particularly ill suited for the study of sexual desire, a topic that has been generally undertheorized by sex researchers. A modern reappraisal of gender and sexual desire is proposed that takes into coordinated account both the biological and sociocultural/political factors that produce and shape subjective sexual desires over the life course. The specific relevance of this approach for three particular topic areas, adolescent sexual maturation, same-sex sexuality, and sexual dysfunction, is addressed. Methodological approaches to the study of gender and sexuality capable of investigating how cultural and biological factors intersect to shape the subjective quality of mens and womens desires at different points in the life course and within different sociocultural and interpersonal contexts are advocated.

Physiological evidence for repressive coping among avoidantly attached adults

Research suggests that the quality of childhood attachments to caregivers influences the development of capacities and strategies for emotion regulation. Avoidantly attached individuals are characterized by emotion-regulation strategies involving the suppression of negative thoughts and feelings. Psychophysiological research on repressive coping suggests that these strategies might be associated with patterns of heightened and escalating sympathetic nervous system reactivity in the absence of correspondingly heightened self-reported affect. The present study tested this hypothesis by subjecting 148 adults to psychological stressors and discussions of attachment-related issues while monitoring their skin conductance level (SCL). Attachment avoidance – but not anxiety – was associated with heightened SCL reactivity to all tasks, especially among women, as well as escalation in reactivity. Additionally, on one stressor avoidance was associated with greater disassociation between subjective and physiological responses. These results have implications for understanding the influence of attachment style on cognitive and physiological aspects of emotion regulation.
