PUNISHMENT IN HUMAN CHOICE: DIRECT OR COMPETITIVE SUPPRESSION?

This investigation compared the predictions of two models describing the integration of reinforcement and punishment effects in operant choice. Deluty's (1976) competitive-suppression model (conceptually related to two-factor punishment theories) and de Villiers' (1980) direct-suppression model (conceptually related to one-factor punishment theories) have been tested previously in nonhumans but not at the individual level in humans. Mouse clicking by college students was maintained in a two-alternative concurrent schedule of variable-interval money reinforcement. Punishment consisted of variable-interval money losses. Experiment 1 verified that money loss was an effective punisher in this context. Experiment 2 consisted of qualitative model comparisons similar to those used in previous studies involving nonhumans. Following a no-punishment baseline, punishment was superimposed upon both response alternatives. Under schedule values for which the direct-suppression model, but not the competitive-suppression model, predicted distinct shifts from baseline performance, or vice versa, 12 of 14 individual-subject functions, generated by 7 subjects, supported the direct-suppression model. When the punishment models were converted to the form of the generalized matching law, least-squares linear regression fits for a direct-suppression model were superior to those of a competitive-suppression model for 6 of 7 subjects. In Experiment 3, a more thorough quantitative test of the modified models, fits for a direct-suppression model were superior in 11 of 13 cases. These results correspond well to those of investigations conducted with nonhumans and provide the first individual-subject evidence that a direct-suppression model, evaluated both qualitatively and quantitatively, describes human punishment better than a competitive-suppression model. We discuss implications for developing better punishment models and future investigations of punishment in human choice.     

Demographic characteristics,social competence,and behavior problems in children with gender identity disorder: a cross-national,cross-clinic comparative analysis

This study examined demographic characteristics, social competence, and behavior problems in clinic-referred children with gender identity problems in Toronto, Canada (N = 358), and Utrecht, The Netherlands (N = 130). The Toronto sample was, on average, about a year younger than the Utrecht sample at referral, had a higher percentage of boys, had a higher mean IQ, and was less likely to be living with both parents. On the Child Behavior Checklist (CBCL), both groups showed, on average, clinical range scores in both social competence and behavior problems. A CBCL-derived measure of poor peer relations showed that boys in both clinics had worse ratings than did the girls. A multiple regression analysis showed that poor peer relations were the strongest predictor of behavior problems in both samples. This study—the first cross-national, cross-clinic comparative analysis of children with gender identity disorder—found far more similarities than differences in both social competence and behavior problems. The most salient demographic difference was age at referral. Cross-national differences in factors that might influence referral patterns are discussed.     

Hormones and Cognition: Current Concepts and Issues in Neuropsychology

This article provides an extensive and comprehensive review of the effects of hormones on cognition. Studies detailing specific neurocognitive functions affected by variation in hormone levels across the life span are presented. Dysregulation of hormone levels is considered from models of both normal and diseased functioning. Patterns of cognitive dysfunction are described for a range of syndromes involving the neuroendocrine system, and evidence of specific neurophysiological mechanisms that can account for these findings is outlined. This review includes discussion of treatment outcomes and the permanency of endocrine-related cognitive dysfunction. The authors present a set of guidelines for clinical neuropsychologists to use for assessment of patients with neuroendocrine system dysfunction. Clinical and methodological issues in research and treatment settings are discussed.     

Parents' Attitudes and Expectations About Children's Cross-Gender Behavior

The goals of the present study were to assessparents' attitudes toward crossgender boys and girls, aswell as to explore possible reasons for differentialevaluations. A total of 224 White parents of five-year old children completed questionnaires probingtheir attitudes toward cross-gender behavior inchildren, and their expectations regarding the futureadult behavior of typical boys, typical girls,cross-gender boys and cross-gender girls. The resultsrevealed that cross-gender boys were more negativelyregarded than crossgender girls and thatmen perceivedmore societal acceptance of cross-gender boys thanwomen. Cross-gender children were predicted tocontinue to show cross-gender behavior in adulthood andto be less psychologically welladjusted as adults thantypical boys and girls. Cross-gender boyswere expected to be less psychologicallywell-adjusted than cross-gender girls. When predictingfuture sexual orientation, cross-gender boys were deemedto have a greater likelihood of being gay thancross-gender girls of being lesbian. Men expectedcross-gender boys to be more likely to show male-malesexual behavior than typical boys inadulthood while women predicted typicalgirls to be more likely to show female-female sexual behavior in adulthoodthan cross-gender girls.     

Mental Health and Incarcerated Youth. I: Prevalence and Nature of Psychopathology

The incarceration of mentally ill youth is a serious problem not receiving the same attention as in adults. In this study, we examine the prevalence of psychopathology and level of behavioral symptomatology in incarcerated youth versus youth receiving community mental health services or hospitalization. We randomly recruited youth from middle South Carolina served by a local CMHC (n = 60), youth served by the state adolescent inpatient program (n = 50), and youth in the S.C. Dept. of Juvenile Justice facilities from the same region (n = 75). We used the DISC-PC 2.3 to evaluate DSM-III-R diagnoses and the CBCL and YSR to evaluate behavioral symptomatology. On the DISC, incarcerated youth had significantly higher mean number of diagnoses and symptoms than CMHC youth, but lower numbers than hospitalized youth. Level of caseness (at least one diagnosis) was 86% in hospital youth, 72% in incarcerated youth, and 60% in CMHC youth. The groups differed in CBCL mean total T, internalizing T, and externalizing T scores as well as mean YSR internalizing T scores. Our results indicate the comparability in level of psychopathology in incarcerated and community-treated populations of youth, and the need to develop diversionary programs to prevent the entry of such youth into the juvenile justice system.     

Law and lamb: AKEDAH and the search for a deep religious symbol for an ecumenical bioethics.

This essay looks at the concept of AKEDAH, the essence of which is the travail of the human condition and the trust in vindication and victory, as a salient and deep metaphor for bioethics. The author first delineates the symbol, then shows its theological and ethical significance, and finally suggests its bioethical applications.     

Rethinking a Familiar Model: Psychotherapy and the Mental Health of Refugees

This paper examines with a somewhat critical eye the primary role that psychotherapy and other clinic-based services currently play in addressing the mental health needs of political refugees in the industrialized countries. Two factors are considered which suggest that refugee mental health needs might be better served by complementing clinic-based treatments with a variety of community-based interventions. The first factor concerns the pervasiveness of psychological distress within refugee communities, coupled with the reluctance of many refugees to utilize formal psychological and psychiatric services. This calls into question both the adequacy and appropriateness of clinical-based services as cornerstones of our response to the mental health needs of refugees. More precisely, it suggests the need to complement such services with a variety of culturally grounded, community-based strategies that do not require attendance in formal mental health settings. Second, recent findings have shown consistently that a considerable amount of the distress reported by refugees is related not to prior exposure to violent events, but to a constellation of exile-related stressors such as the loss of one's community and social network, the loss of important life projects, changes in socioeconomic status and related concerns about economic survival, the loss of meaningful structure and activity in daily life, and the loss of meaningful social roles. It is suggested that while psychotherapy can play an important adjunctive role in helping people confront these exile-related stressors, they may most effectively be addressed through targeted community-based interventions. Examples of such community-based approaches are briefly described, and suggestions are offered for community-level strategies that might be explored. The paper concludes by emphasizing the complementary nature of clinical and community-based programs, and by suggesting that psychotherapy might best be conceptualized as one component of a more comprehensive approach to addressing the mental health needs of refugee communities.     

Genetic and environmental contributions to the co-occurrence of depressive personality disorder and DSM-IV personality disorders

One of the main controversies with regard to depressive personality disorder (DPD) concerns the co-occurrence with the established DSM-IV personality disorders (PDs). The main aim of this study was to examine to what extent DPD and the DSM-IV PDs share genetic and environmental risk factors, using multivariate twin modeling. The DSM-IV Structured Interview for Personality was applied to 2,794 young adult twins. Paranoid PD from Cluster A, borderline PD from Cluster B, and all three PDs from Cluster C were independently and significantly associated with DPD in multiple regression analysis. The genetic correlations between DPD and the other PDs were strong (.53-.83), while the environmental correlations were moderate (.36-.40). Close to 50% of the total variance in DPD was disorder specific. However, only 5% was due to disorder-specific genetic factors, indicating that a substantial part of the genetic vulnerability to DPD also increases the vulnerability to other PDs.     

Facilitating the Pygmalion effect: The overlooked role of subordinate perceptions of the leader

For many years, the Pygmalion effect has served as a colourful, conceptual reminder of the power of supervisory expectations in enhancing subordinate performance. However, regardless of the myriad of studies that have sought to replicate this effect and identify its parameters, little attention has actually been paid to the processes underlying this phenomenon. Rather, the existing model implies that the subordinate is an ‘always‐willing’, yet somewhat ‘passive’ recipient of Pygmalion‐oriented leader efforts. Our theoretical paper unpacks the role of subordinate perceptions of the leader and considers how it can influence receptiveness to the leader's Pygmalion‐oriented efforts. By revisiting and building upon the original Pygmalion model, we attempt to enrich our understanding of this phenomenon, as well as to offer insight into why not all Pygmalion leader efforts are equally successful.
