On the acquisition of pattern encoding skills

These experiments evaluated two potential sources of developmental changes in pattern encoding: advances at a perceptual level enabling better representation of the spatial relations among elements, and acquisition of metaperceptual knowledge supporting a deliberate search for distinguishing features. Children 6, 10, and 12 years old, as well as adults encoded high level distortions of random dot configurations. These materials were originally used by Posner and Keele (1968). In the first experiment, subjects matched exemplars to their prototypes. In two other experiments, subjects learned to categorize distortions under two different training conditions—one designed to focus attention on individual exemplars, the other designed to facilitate comparison of exemplars within and across categories. Following training, subjects classified new instances into the learned categories. The same pattern of developmental change was found in the matching task and in the classification task: major gains between ages 6 and 12 and continued gains to adulthood. Several aspects of the results identify change at a perceptual level after age 10 as a source of this development, independent of possible contributions from metaperceptual advances.     

Effects of Probabilistic Rewards on Recycling Attitudes and Behavior1

Two studies compared the attitudinal and behavioral effects of certain rewards and lotteries. In a laboratory experimental study, lotteries produced significantly more attitude change than cash payments. The greatest attitude change occurred among lottery winners. In a quasi-experimental field study, subjects rewarded with lottery tickets recycled glass and newspaper more frequently than subjects receiving other individual or group rewards. Attitude change was not affected by the type of reward Implications for the design of incentive programs to increase prosocial behavior are discussed     

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.     

Empathy and identification in Von Donnersmarck's The Lives of Others

Florian Henckel von Donnersmarck's The Lives of Others, set in the German Democratic Republic in 1984, five years before the fall of the Berlin Wall, has been called the first accurate depiction of the psychological terror wielded by the Stasi, the East German secret police, who safeguarded the dictatorship of the proletariat. The film is about the psychological and political transformation of a Stasi officer, Wiesler, who undertakes the surveillance of a prominent playwright and his actress lover. The mechanisms through which Wiesler comes to empathize and identify with the subjects of his investigation, as he observes and listens in on the rich blend of passion, poetry, and politics that characterizes their lives, are explored in depth. Wiesler's transformation is based in part on the capacity to form implicit models of the behavior and experiences of others, based on the mirror neuron system, that Gallese and his colleagues call "embodied simulation." Underpinning the processes of empathy and identification so central to this film, embodied simulation is an unconscious and prereflexive mechanism through which the actions, emotions, and sensations we observe activate internal representations of the bodily and mental states of the other. Embodied simulation also expands our understanding of the power of the primal scene, which has long been identified as a major organizer of unconscious fantasies and conflicts throughout life, and which forms the central metaphor of the film. Embodied simulation scaffolds our aesthetic response to art, music, and literature, underlies the dynamics of spectatorship, and potentially catalyzes resistance to totalitarian mass movements.     

Every time you go away: changes in affect, behavior, and physiology associated with travel-related separations from romantic partners

This study investigated changes in day-to-day affect, behavior, and physiology (hypothalamic-pituitary-adrenocortical axis activity) associated with temporary physical separations from romantic partners (such as those brought about by work-related travel). Daily diaries and measures of salivary cortisol were collected from 42 couples over a 21-day period that was timed to coincide with a naturally occurring 4- to 7-day separation. There were significant changes from preseparation to separation and from separation to reunion in the quality of partners' interactions, their positive and negative affect, sleeping problems, subjective stress, physical symptoms, and cortisol levels. Separation and reunion effects were generally more pronounced in homebound partners, partners with high attachment anxiety, and partners who had less contact with each other during the separation. Separation and reunion effects were not moderated by relationship length, relationship satisfaction, how often couples underwent separations, or the presence of children in the home. The results are discussed with respect to the role of daily proximity and contact between partners for day-to-day affective and physiological regulation.     

Cross-validation of Levenson's Psychopathy Scale in a sample of federal female inmates

Levenson, Kiehl, and Fitzpatrick's Self-Report Psychopathy Scale (LSRPS) is evaluated to determine the factor structure and concurrent validity of the instrument among 430 federal female inmates. Confirmatory factor analysis fails to validate the expected 2-factor structure. Subsequent exploratory factor analysis reveals a 3-factor structure (egocentric, antisocial, and callous), where each factor accounts for significant variance in scores on several theoretically relevant measures. Higher scores on the antisocial factor of the LSRPS are associated with a history of varied psychopathological and negative legal outcomes, suggesting evidence of concurrent validity. However, the egocentric and callous factors do not seem to measure precisely the same construct as the primary psychopathy factor from the Levenson et al. study. The 3-factor structure proposed here has been proposed by other researchers and found in other samples of psychopathy in female inmates. Implications for both research and clinical practice using the LSRPS with female inmates are discussed.     

Interrelated and interdependent

The possibilities for building and nourishing connections among the social, cultural, neuroscientific, biological, and cognitive sciences in the service of understanding children and their development are tremendously exciting. Crossing, and integrating across, disciplinary boundaries, especially those disciplines relating to biology/neuroscience, society/culture, cognition, emotion, perception, and motor function has greatly increased over the last decade and hopefully will increase exponentially in the future. All of these aspects of being human are multiply-interrelated and we need to make far more progress in understanding those interrelations.     

A developmental view of therapeutic bonding in the family: treatment of the disconnected family

Data from an ongoing research study have been used to identify a subgroup of families of severely ill, young adults who present formidable treatment challenges to the family therapist. The disconnected family is characterized by disturbances in attachment between one or both parents and the patient. In many cases, disturbances in attachment and caretaking in the family of origin are reported for the parents in these families. Disconnected families that also have intense emotional styles of relating are particularly difficult to treat. A treatment model that focuses on intergenerational attachment issues is described.     

Emerging Perspectives on Distinctions Between Romantic Love and Sexual Desire

Abstract— 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 individual's 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.     

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.
