Contribution of imitative suicide to the suicide rate in prisons

Suicide rates in prisons are high. Our aim was to investigate the contribution of imitative suicide to the prison suicide rate. We used Knox tests for space-time clustering in a case register of natural and self-inflicted deaths in prisons in England and Wales and model simulations to estimate the effect size. We found significant space-time clustering among 657 self-inflicted deaths in 90 prisons over 10 years but no space-time clustering among 430 deaths from natural causes in 87 prisons over this period. Model simulations with an imitation rate of 5.8% (CI 1%-11%) reproduced the observed space-time clustering.     

Are Longshots Only for Losers? A New Look at the Last Race Effect

There is evidence that betting on longshots increases in the last race of a day of horse racing. Previous accounts have assumed that the phenomenon is driven by bettors who have lost money and are trying to recoup their losses. To test this assumption of “reference dependence,” three laboratory experiments simulated a day at the races: In each of several rounds, participants chose either (i) a gamble with a small probability of a large gain and a large probability of a small loss (the “longshot”) or (ii) a gamble with a moderate chance of a small gain or a small loss (the “favorite”). The first two experiments employed a game played for points, while a third experiment included monetary incentives and stimuli drawn from a real day of racing. These experiments provide a clear demonstration of the last race effect in a laboratory setting. However, the results indicate that the effect is largely reference independent: Participants were more likely to choose the longshot in the last round regardless of whether, and how much, they had won or lost in previous rounds. Winning or losing, bettors prefer to “go out with a bang” at the end of a series of gambles. Copyright © 2015 John Wiley & Sons, Ltd.     

Traumatic Incidents and Experiences of Racism and Sexism: Examining Associations with Components of Critical Consciousness for System‐Involved Girls of Color

Scholarship identifies critical consciousness as a key developmental asset in promoting the well‐being of adolescents experiencing multiple socio‐structural axes of oppression. Girls of color at acute risk for legal system involvement or re‐involvement are absent from this literature. They are a critical population in which to examine this construct given their experiences of oppression and the myriad benefits of critical consciousness. The current study addresses this gap by examining traumatic incidents and experiences of racism and sexism as correlates of critical reflection and action among a sample of girls (N = 220; Mean age = 14.5 years; SD = 1.3 years). Using path analysis and multigroup modeling, we examine direct associations between these three manifestations of structural oppression and critical consciousness and explore the interplay of traumatic incidents, and racism and sexism in girls’ critical consciousness development. Findings suggest that experiences of sexism and racism, uniquely and positively predict critical action, but not critical reflection. Surprisingly, girls’ experiences of traumatic incidents do not predict reflection or action. Finally, multigroup analyses show no evidence that these associations vary by the interplay of traumatic incidents, racism, and sexism. Implications for community psychology values and juvenile legal system practice and policy are discussed.     

Family Experience of Safe: A New Intervention for Families of Children with a Diagnosis of Autism Spectrum Disorder

Systemic Autism-related Family Enabling (SAFE) is a new intervention for families of children with a diagnosis of Autism Spectrum Disorder (ASD). SAFE responds to international and national recommendations for improved care and the reported needs of families. SAFE draws from Family Therapy techniques, Attachment Narrative Therapy and known preferences of individuals with autism. Twenty two families of a child with a diagnosis of ASD severity level 1 or 2 were recruited. The families attended five 3-hour sessions. Family members completed the Helpful Aspects of Therapy Questionnaire (HAT) after each session. Analysis of the HAT data revealed that adults and children experienced SAFE to be helpful which was elaborated in terms of the following themes: therapist as helping reflection, increased understanding, feeling closer, more confident to reflect and problem solve, improved communication and feeling less alone and isolated. The findings are discussed to consider how SAFE can be improved and implemented to offer support for families. SAFE is a good candidate to fill a gap in autism related care.

     

Investigating the mechanisms of visually-evoked tactile sensations

When attempting to detect a near-threshold signal, participants often incorrectly report the presence of a signal, particularly when a stimulus in a different modality is presented. Here we investigated the effect of prior experience of bimodal visuotactile stimuli on the rate of falsely reported touches in the presence of a light. In Experiment 1, participants made more false alarms in light-present than light-absent trials, despite having no experience of the experimental visuotactile pairing. This suggests that light-evoked false alarms are a consequence of an existing association, rather than one learned during the experiment. In Experiment 2, we sought to manipulate the strength of the association through prior training, using supra-threshold tactile stimuli that were given a high or low association with the light. Both groups still exhibited an increased number of false alarms during light-present trials, however, the low association group made significantly fewer false alarms across conditions, and there was no corresponding group difference in the number of tactile stimuli correctly identified. Thus, while training did not affect the boosting of the tactile signal by the visual stimulus, the low association training affected perceptual decision-making more generally, leading to a lower number of illusory touch reports, independent of the light.     

The influence of subjective life expectancy on retirement transition and planning: A longitudinal study

This study examines the construct of subjective life expectancy (SLE), or the estimation of one's probable age of death. Drawing on the tenets of socioemotional selectivity theory (Carstensen, Isaacowitz, & Charles, 1999), we propose that SLE provides individuals with their own unique mental model of remaining time that is likely to affect their retirement planning and decision making. Longitudinal data from 1908 participants showed that SLE measured at Time 1 predicted mature-aged workers' intended retirement age and the extent that they were engaged in retirement preparation 12 months later at Time 2. Furthermore, a shorter SLE at Time 1 increased the odds of actual retirement by Time 2 after controlling for a set of known predictors of retirement. In contrast, a longer SLE at Time 1 increased the odds that a Time 1 retiree had returned to paid work by Time 2. The discussion highlights ways in which SLE can inform financial and vocational counselling for late career decision-makers.     

New approach illuminates how memory systems switch

Whereas the classic view of systems consolidation involves an initial hippocampal-dependent memory later giving way to neocortical structures, a recent study using precisely-timed optogenetic silencing of key brain areas reveals a more complex and dynamic interaction between systems competing for control over the expression of contextual fear memories.     

The Relationship Between Deployment and Turnover in Australian Navy Personnel

Increases in the frequency of operations tempo have focused attention on the relationship between deployment and separation from military service. This retrospective study explored the association between deployment and turnover over a 10-year period in Royal Australian Navy (RAN) personnel. Participants were 2355 males who served in the RAN during the period of the 1991 Gulf War (August 1990–September 1991); approximately half had been deployed to that conflict. Data were collected 10 years later as part of the Australian Gulf War Veterans' Health Study. During that 10-year period, 61% of participants left the RAN. The likelihood of separation decreased as number of deployments increased even when controlling for age, rank, and length of service. Personnel deployed to the 1991 Gulf conflict did not have a significantly higher risk of separation. The results provide evidence that deployment is not necessarily a risk factor for separation.     

A Trust-Based Home Intervention for Special-Needs Adopted Children: A Case Study

Research on the effects of abuse, neglect, and other traumas in early childhood has consistently demonstrated severe deficits that can be prevalent across the life span. Costs associated with addressing such deficits in special-needs children can strain families and are an immense financial burden to society. Trust-Based Relational Intervention® is an intervention modality that targets the attachment system as part of a dynamic system of development. Presented is a summary of the costs of addressing the sequelae of childhood abuse and neglect, a brief overview of Trust-Based Relational Intervention, and a case study demonstrating the efficacy of this intervention with an adopted special-needs child in a home-based setting.
