Childhood abuse and vulnerability to depression: Cognitive scars in otherwise healthy young adults

Models of depression vulnerability posit that negative early experiences, such as exposure to childhood abuse (CA), increase vulnerability to depression later in life. Though most victims of CA do not go on to develop depression, the question remains as to whether these individuals retain cognitive ‘scars’ that may contribute to depression vulnerability. The present study examined the relationship between self-reported, retrospective CA and cognitive vulnerability to depression in a carefully selected sample of young adults without current or past psychopathology. We measured cognitive vulnerability with both a self-report questionnaire, the Dysfunctional Attitudes Scale (DAS), and a measure of information processing bias, the Scrambled Sentences Test (SST). Self-reported severity of CA was associated with increased cognitive vulnerability to depression on both the DAS and SST. Vulnerability to depression as measured by the SST, but not by the DAS, prospectively predicted increases in depressive symptoms over a 6-month period. Scores on the SST also interacted with CA to predict increases in depressive symptoms. These findings demonstrate the pernicious effects of CA even in those without current or past psychopathology.     

Deconstructing delusions: A qualitative study examining the relationship between religious beliefs and religious delusions

Delusions have been conceptualized as forming in response to experience, yet the relationship between religious belief, and beliefs regarded as delusional, has received little research attention. This is despite the high prevalence of delusions featuring religious content. Semi-structured interviews were conducted with seven participants who had been diagnosed as experiencing delusions. Participants from a range of religious backgrounds were asked about their religious experiences and beliefs, family background and experiences of psychosis. These interviews were analysed qualitatively. Whilst religious background affected the content of delusions, the nature of delusions appeared to be influenced by other factors, such as early family experiences, particularly an absent parent and conflict within the family. Individuals often used a religious framework to understand unusual experiences, and there seemed to be a role for the process of identification and wish fulfilment in influencing delusional content. Whilst this research is clearly limited by its exploratory nature, it offers a possible framework of understanding which helps make sense of religious delusions, and suggests approaches which may be helpful in recovery.     

Book Reviews

Avicenna (d. 1037) and Tūsī (d. 1274) have different doctrines on the contradiction and conversion of the absolute proposition. Following Avicenna's presentation of the doctrine in Pointers and reminders, and comparing it with what is given in Tūsī's commentary, allow us to pinpoint a major reason why Avicenna and Tūsī have different treatments of the modal syllogistic. Further comparison shows that the syllogistic system Rescher described in his research on Arabic logic more nearly fits Tūsī than Avicenna. This in turn has consequences for analysing Avicenna's logic, and for writing the history of a fascinating period of change and diversity in the discipline in the medieval Islamic world.     

Yielding to Deviant Temptation: A Quasi-Experimental Examination of the Inhibiting Power of Intrinsic Religious Motivation

ABSTRACT

The deviance-inhibiting power of religion is among the oldest criminological inquiries. To date, the extant empirical literature contains mixed and oftentimes contradictory evidence. Social scientists have argued that the ambiguous body of religion-deviance evidence is attributable, in some part, to known methodological weaknesses. This study responds to the criticisms of prior research by utilizing a validated measure of religiosity, employing a quasi-experimental design, and observing actual deviant behavior. The results of this study find that religion is indeed a powerful predictor of deviant behavior.     

An implicit basis for the retention benefits of random practice

The cognitive effort explanations of contextual interference (CI) and implicit motor learning represent a paradox in which cognitive involvement is seen to be advantageous or disadvantageous for learning. The authors aimed to resolve this paradox by measuring cognitive effort and working memory dependence during low and high CI practice on two Australian Rules Football tasks (kicking and handball). Measures of cognitive effort included: kicking and handball outcome performance during acquisition and during a test of retention, performance on a probe reaction time task during a sample of acquisition trials, and self-reported levels of cognitive effort. Measures of implicit and explicit learning included kicking and handball performance during a secondary task transfer, and self-report verbal protocols (number of verbal rules and hypotheses reported). The results suggest that high CI may cause an implicit mode of learning, perhaps due to the interference caused by task switching. However, these findings are restricted to the more complex of the 2 tasks (kicking).     

Channels of Change: Contrasting Network Mechanisms in the Use of Interventions

This study informs community science, and seeks to narrow the research-to-practice gap, by examining how the interpersonal networks within a setting influence individuals' use of interventions. More specifically, it explores the role of two network mechanisms-cohesion and structural similarity-in urban elementary school teachers' use of interventions designed to improve academic and behavioral outcomes for students. Lagged regression models examine how position in advice giving networks influenced weekly use of the daily report card and peer assisted learning by kindergarten through fourth grade teachers in three schools. Results indicate that intervention use spreads among teachers with similar patterns of advice-giving relationships (i.e., via structural similarity), rather than from teachers who are sources of advice (i.e., via cohesion). These results are consistent with findings in other settings, and suggest that researchers wishing to increase the use of an intervention should select change agents based on their patterns of their relationships, rather than on their direct connections.
