Reward dominance and passive avoidance learning in adolescent psychopaths

This study tests predictions that adolescent psychopaths are hyperresponsive to rewards (Quay, 1988) and deficient in passive avoidance learning (Newman & Kosson, 1986). Forty male adolescent juvenile offenders were divided into psychopaths and nonpsychopaths using cluster analysis. Subjects were administered a passive avoidance learning task which required learning when to respond to cards associated with either reward or punishment. Results showed a greater responsivity to reward in psychopaths, with no group differences in passive avoidance errors. Results lend support to the view that psychopaths tend to focus on the prospect of reward under conditions of mixed incentives and, when sufficiently motivated, are capable of improved performance. Together with findings of recent psychophysiological studies, these results suggest that adolescent psychopaths may have latent abilities which could have treatment implications.The authors are greatly indebted to the boys and staff of the testing institution for their kind cooperation in this study. Thanks are also due to Dr. Rand Wilcox for statistical consultation and Cheryl Eurton and Marni Ayers for assistance in data coding.     

TOWARDS AN INTERNATIONAL PROFESSION OF CLINICAL PSYCHOLOGY: AN ANGLO-SWEDISH PERSPECTIVE

Previous reviews of the international trends in the development of clinical psychology as a profession have identified the United Kingdom and the Nordic States as countries where the role of the psychologist is approximating that in North America. The article presents a review of the historical and current influences on the development of clinical psychology in the United Kingdom and in Sweden. In Europe, where clinical psychology is mainly a Health Service profession rather than a private practice, independence of the management and medical responsibility of the psychiatrist has become more of a key issue. Of the two major ‘schools’ of clinical psychology, identified in Britain with the behavioral approach of the Maudsley Institute of Psychiatry and the psychodynamic approach of the Tavistock Clinic, the behavioral school tended to dominate in Britain until the 1970s. In Sweden, the psychodynamic approach importing many of the aspects of British Object Relations Theory, gained ascendence. This resulted in a split between the more academic form of clinical psychology in Sweden, which had produced research of international importance (e.g. the role of psychological factors in stress-related illness), and professional education in psychology with its emphasis on psychotherapeutic training. Whereas in Britain, during the 1970s, clinical psychology broke away from psychiatry, became more eclectic, and entered the general medical and health areas, these changes failed to take place in Sweden. On the other hand, private practice amongst psychologists in Sweden has shown a dramatic increase during recent years and there are now some clear trends towards eclecticism in the education of psychologists. The issue of medical responsibility remains unresolved in Sweden. That British clinical psychology has reached more progressive and cordial professional relationships in this respect may be, in part, due to the status of the scientist-practitioner role that the initial behavioral emphasis achieved. The major contributions of and trends in British and Swedish clinical psychology are discussed with a view to identifying international trends.     

Why Do People Save? Attitudes to,and Habits of Saving Money in Britain

This study investigates the relationship between demographic (age, sex, education, vote, and income), psychological beliefs (alienation, Protestant Work Ethic, and conservatism), and attitudes toward, as well as habits of, saving money, in Britain. Over 250 people from a variety of backgrounds completed a number of standardized self-report measures. A factor analysis of the attitude toward saving scale revealed five clearly interpretable factors, which were later computed into five subscale scores. Analysis of variance showed that age and education most differentiated subjects' attitudes toward saving. A canonical correlational analysis showed age, vote, income, and alienation were clearly related to various attitude toward saving factors. Analysis of the saving habits questionnaire showed that sex, age, and income were among the most important discriminators of saving habits. These results are discussed in terms of economic socialization and various social policy decisions are considered.     

Wendy's Story: analytic perspectives on J. M. Barrie's Peter and Wendy

This essay is a study of Peter and Wendy, J. M. Barrie's 1911 novel based on his 1904 play Peter Pan. Utilizing Jungian and Kleinian theory, the tale is treated as an expression of Wendy's psyche in transformation, tracking her passage into puberty and the transition from omnipotent narcissism towards depressive concern which accompanied her differentiation from idealized identification with her mother. The resultant changes in Wendy's parental imagos are given particular emphasis, especially the moves towards the integration of her split paternal imago, symbolized by Peter Pan and Captain Hook. This enables Wendy's fuller engagement with the Oedipus situation, resulting in her assimilation of unconscious aspects of the instinctual feminine. In turn, she opens to a conception of parental intercourse which is more reality orientated and allows an internal sense of coupledom vital for her own capacity to form adult relationships.     

Health, well-being, and social indicators among monks, prisoners, and other adult members of an Open University Cohort in Thailand

This study has brought together two seemingly socially extreme population subgroups to compare their health and social well-being. These groups had in common restricted living arrangements and aspirational enrollment. As well, they are part of the population-based Thai Cohort Study (TCS) of 87,134 adult Open University students residing throughout the country. Analysis was restricted to men aged 20–39 years resulting in 711 monks, 195 prisoners and 29,713 other cohort members. For physical health, we have found certain conditions such as tuberculosis or malaria much more common among prisoners, while goiter and liver diseases were more common among monks. This could be due to prison living arrangements for the former and region of residence for the latter. For other social outcomes, lower trust, higher economic stress and lower personal well-being was noted for prisoners compared to other groups. Findings here with regard to spirituality and religion are encouraging with almost no difference reported between prisoners and other cohort members implying that trust-building and other social intervention for prisoners could be activated through prevalent religious beliefs and practices and with continuing support from Thai prison authorities.     

Psychopathic Traits and Physiological Responses to Aversive Stimuli in Children Aged 9–11 Years

Atypical eletrodermal and cardiovascular response patterns in psychopathic individuals are thought to be biological indicators of fearless and disinhibition. This study investigated the relationship between psychopathic traits and these autonomic response patterns using a countdown task in 843 children (aged 9-10?years). Heart rate (HR) and non-specific skin conductance responses (NS-SCRs) were recorded while participants anticipated and reacted to 105?dB signaled or un-signaled white-noise bursts. Using multilevel regression models, both larger HR acceleration and fewer NS-SCR were found to be significantly associated with psychopathic traits during anticipation of signaled white-noise bursts. However, two divergent patterns appeared for HR and SCR: (1) larger HR acceleration was specific to the callousness-disinhibition factor of psychopathic traits while reduced NS-SCR was only associated with the manipulative-deceitfulness factor; (2) the negative association between the manipulative-deceitfulness factor and NS-SCR was only found in boys but not in girls. These findings replicated what has been found in psychopathic adults, suggesting that autonomic deficits present in children at risk may predispose them to later psychopathy. The divergent findings across psychopathic facets and sexes raised the possibility of different etiologies underlying psychopathy, which may in turn suggest multiple treatment strategies for boys and girls.     

G(o) activation is required for both appetitive and aversive memory acquisition in Drosophila

Heterotrimeric G(o) is an abundant brain protein required for negatively reinforced short-term associative olfactory memory in Drosophila. G(o) is the only known substrate of the S1 subunit of pertussis toxin (PTX) in fly, and acute expression of PTX within the mushroom body neurons (MB) induces a reversible deficit in associative olfactory memory. We demonstrate here that the induction of PTX within the α/β and γ lobe MB neurons leads to impaired memory acquisition without affecting memory stability. The induction of PTX within these MB neurons also leads to a significant defect in an optimized positively reinforced short-term memory paradigm; however, this PTX-induced learning deficit is noticeably less severe than found with the negatively reinforced paradigm. Both negatively and positively reinforced memory phenotypes are rescued by the constitutive expression of G(o)α transgenes bearing the Cys(351)Ile mutation. Since this mutation renders the G(o) molecule insensitive to PTX, the results isolate the effect of PTX on both forms of olfactory associative learning to the inhibition of the G(o) activation.     

Molecular and behavioral changes associated with adult hippocampus-specific SynGAP1 knockout

The synaptic Ras/Rap-GTPase-activating protein (SynGAP1) plays a unique role in regulating specific downstream intracellular events in response to N-methyl-D-aspartate receptor (NMDAR) activation. Constitutive heterozygous loss of SynGAP1 disrupts NMDAR-mediated physiological and behavioral processes, but the disruptions might be of developmental origin. Therefore, the precise role of SynGAP1 in the adult brain, including its relative functional significance within specific brain regions, remains unexplored. The present study constitutes the first attempt in achieving adult hippocampal-specific SynGAP1 knockout using the Cre/loxP approach. Here, we report that this manipulation led to a significant numerical increase in both small and large GluA1 and NR1 immunoreactive clusters, many of which were non-opposed to presynaptic terminals. In parallel, the observed marked decline in the amplitude of spontaneous excitatory currents (sEPSCs) and inter-event intervals supported the impression that SynGAP1 loss might facilitate the accumulation of extrasynaptic glutamatergic receptors. In addition, SynGAP1-mediated signaling appears to be critical for the proper integration and survival of newborn neurons. The manipulation impaired reversal learning in the probe test of the water maze and induced a delay-dependent impairment in spatial recognition memory. It did not significantly affect anxiety or reference memory acquisition but induced a substantial elevation in spontaneous locomotor activity in the open field test. Thus, the present study demonstrates the functional significance of SynGAP1 signaling in the adult brain by capturing several changes that are dependent on NMDAR and hippocampal integrity.     

Happiness, Mental Health, and Socio-Demographic Associations Among a National Cohort of Thai Adults

Research on happiness has been of interest in many parts of the world. Here we provide evidence from developing countries; this is the first analysis of happiness among a cohort of Thai distance learning adults residing throughout the country (n?=?60,569 in 2009). To measure happiness, we tested use of the short format Thai Mental Health Indicators (TMHI), correlating each domain with two direct measures of happiness and life satisfaction. Several TMHI domains correlated strongly with happiness. We found the mental state and the social support domains moderately or strongly correlated with happiness by either measure (correlation coefficients 0.24–0.56). The other two TMHI domains (mental capacity and mental quality) were not correlated with happiness. Analysis of socio-demographic attributes and happiness revealed little effect of age and sex but marital status (divorced or widowed), low household income, and no paid work all had strong adverse effects. Our findings provide Thai benchmarks for measuring happiness and associated socio-demographic attributes. We also provide evidence that the TMHI can measure happiness in the Thai population. Furthermore, the results among Thai cohort members can be monitored over time and could be useful for comparison with other Southeast Asian countries.     

The dark side of career preference: dark side traits,motives, and values

Over 2000 people completed two validated questionnaires: one measuring “dark side” personality traits and the other a measure of values and preferences that indicates the type of work that an individual would like to do and is best suited for. Dark side variables (and demographics) accounted for between 11% (science) and 46% (affiliation) variance in specific vocation related values. Factor analysis suggested three overall value/vocation factors (enterprising, traditional, and social) and three dark side variables (moving against, away from, and toward others). The three dark side factors predicted around a third of the variance in favoring enterprising and social occupations. Implications for vocational guidance and limitations of the study are considered.
