Assessment of Psychopathic Traits in Singaporean Adolescents: Validation of the Antisocial Process Screening Device (APSD)

There is little knowledge available concerning psychopathic traits in Asian adolescents; a lack of a suitable measurement instrument for assessing psychopathy in Asian societies may account for this. This study aimed to validate a widely used scale in the West — the Antisocial Process Screening Device (APSD) — in Singaporean school-based and at-risk adolescents. Using an exploratory factor analysis (EFA) and a confirmatory factor analysis (CFA), this study examined the two-factor (i.e., grandiose-manipulative/impulsive traits and callous-unemotional traits) and three-factor (i.e., grandiose-manipulative traits, impulsivity, and callous-unemotional traits) models of the APSD in 1027 school-based and 113 at-risk adolescents. School samples are adolescents from three secondary schools, while at-risk samples are adolescents who manifest different types of delinquent behaviors and are either placed in more structured settings or need closer supervision although they have not violated the law. Gender invariance was further tested in the school-based sample by conducting a multigroup CFA. The convergent validity of the APSD was also investigated in the school-based sample. For the school-based adolescents, the APSD revealed that the three-factor model provided a superior fit over the two-factor model and the factorial invariance across gender. Significant relationships between the three dimensions of the APSD and aggression and delinquency support the convergent validity of the APSD. As for the at-risk adolescents, both the two- and three-factor models were acceptable, but the two-factor model was preferred as it was parsimonious and it aligned with the conceptualized characteristics of psychopathic traits. Findings suggest that the APSD is a reliable and sound instrument for measuring psychopathic traits in Asian school-based and at-risk adolescents.     

Time and number discrimination in a bisection task with a sequence of stimuli: a developmental approach

Children, aged 5 and 8 years, and adults were tested in a bisection task with a sequence of stimuli in which time and number co-varied. In a counting and a non-counting condition, they were instructed either to process the duration of this sequence while ignoring the number of stimuli (temporal bisection), or to process the number of stimuli while ignoring the duration (numerical bisection). In the temporal bisection task, number interfered with the 5-year-olds' temporal performance, indicating that young children did not process time and number independently in a sequence of stimuli when they had to attend to duration. However, number interference decreased both with age and counting strategy. In contrast, in the numerical bisection task, duration did not interfere with numerical discrimination for any age group.     

Psychological consequences of collective violence in childhood: the case of Monterrey,Mexico / Consecuencias psicológicas de la violencia colectiva en la niñez: el caso de Monterrey,México

Abstract

During the last years, different types of violence have severely damaged Mexico. In this paper we examine the consequences that violence could have in children, one of the most vulnerable segments of society. In short, we predict that exposure to any type of violence will lead to higher depression and that this could be explained through the effects of violence on childhood well-being. Our hypothesis was supported in two studies, showing that exposure to street violence (Study 1, N = 607) and exposure to collective violence (Study 2, N = 172) can increase childhood depression. Moreover, in both studies, this effect was explained by the decrease of childhood well-being caused by violence exposure. The implications of these results are discussed.     

A PET meta‐analysis of object and spatial mental imagery

Neuroimaging studies have described the functional neuroanatomy of mental imagery. Taken separately, specific studies vary in the nature of the task used and are limited by statistical power and sensitivity. We took advantage of a multistudy PET database of 54 subjects acquired in our laboratory to reveal the neural bases of spatial versus object mental imagery tasks. Our first goal was to evaluate to what extent the activated foci elicited by both object and spatial studies overlap. A second aim was to compare activations elicited by spatial imagery tasks to those elicited by object imagery tasks. We also explored applying regression analyses to the relationships between the scores on the Mental Rotations Test (MRT) and changes in regional cerebral blood flow (rCBF) during spatial and object imagery tasks. This meta‐analysis yielded the following observations: (1) both spatial and object imagery tasks shared a common neural network composed of occipitotemporal (ventral pathway) and occipitoparietal (dorsal pathway) regions and also by a set of frontal regions (related to memory); (2) the superior parietal cortex was more strongly implicated during spatial imagery; (3) object imagery specifically engaged the anterior part of the ventral pathway, including the fusiform, parahippocampal, and hippocampal gyrus; (4) object imagery activated the early visual cortex, whereas spatial imagery induced a deactivation of the early visual cortex; (5) blood flow values in some of the regions noted above were positively correlated with scores on the MRT: the higher the subjects performed on the MRT, the more pronounced the rCBF was in these regions. These results may reconcile some of the apparent discrepancies among previous studies concerning the activation of early visual cortex in mental imagery. They also contribute to a better knowledge of the neural bases of object and spatial mental imagery.     

The richness of ordinary life: Religious justification among Chile's business elite

Based on the analysis of 75 in‐depth interviews with managers and businessmen of Chile's main economic conglomerates, this article is concerned with the justification, on religious and moral grounds, of the establishment of a neo‐liberal economic model during Augusto Pinochet's regime (1973–1989) and, most importantly, with the representation of business as a religious vocation. The value granted to wealth creation as a path to salvation, as formulated by the conservative religious movements Opus Dei and the Legionaries of Christ, is one possible response to the Church's call in Vatican II for the greater involvement of the laity in their cultures and societies. In the context of an increase in pluralism during the 1960s and 1970s, the perceived shift of the Catholic Church to the Left, and the threat that the political project of Salvador Allende's socialist government (1970–1973) posed to the elite's centenary lifestyle, the practice of more conservative forms of Catholicism has allowed for a restoration of the historical bond between the elite and its religious tradition. The case of Chile's elite can be seen as an example of an increase in pluralism which does not lead to a weakening of religious belief and practice, but to their strengthening.     

Effects of gender and sex role orientation on help-seeking attitudes

This study investigated the effects of gender and sex role orientation (masculinity and femininity) on attitudes toward seeking professional psychological help in a sample of 163 student trainee teachers (52 males and 111 females) in Singapore. The mean age of students was 25.39 years (SD = 3.80). ANOVAs revealed statistically significant main effects for gender and femininity on attitudes toward help-seeking. Specifically, females were reported to have more positive overall attitudes toward professional help-seeking and were more willing to recognize a personal need for professional help compared to males. Femininity significantly influenced students’ level of stigma tolerance. These findings suggest that both gender and sex role orientation play an independent role in influencing help-seeking attitudes. In addition, these variables appear to have a differential impact on different aspects of helpseeking.

Personality, biographical characteristics, and job interview success: a longitudinal study of the mediating effects of interviewing self-efficacy and the moderating effects of internal locus of causality

In this study, the authors developed and tested a model of performance in job interviews that examines the mediating role of interviewing self-efficacy (I-SE; job applicants' beliefs about their interviewing capabilities) in linking personality and biographical background with interview success and the moderating role of locus of causality attributions in influencing the relationship between interview success and subsequent I-SE. The authors tested their model (over 5 months' duration) with matched data from 229 graduating seniors, firms, and university records. Hierarchical regression analyses demonstrated I-SE mediated the effects of Extraversion, Conscientiousness, and leadership experience on interview success. Locus of causality attributions for interview outcomes moderated the relationship between interview success and subsequent I-SE. Theoretical and practical implications are discussed.
