A Review of Reviews Examining Neurological Processes Relevant to Impact of Parental PTSD on Military Children: Implications for Supporting Resilience

In this study, 10 recent meta-analytic and systematic review studies were synthesized on the neurological underpinnings of stress and trauma with implications for the impact of parental post-traumatic stress disorder (PTSD) and resilience among military children. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) group guidelines and utilizing a validated quality assessment tool, this systematic review of reviews incorporated results from more than 35,971 individuals with stress exposures, effects, or disorders and healthy controls. This synthesis found support for important gene, physiology, and environment correlations and interactions that predict increased risk for stressful life events and PTSD, but not direct transmission, among military children. Future research is needed to determine if these constitute indirect pathways of intergenerational transmission in military children.     

Alcohol-related knowledge and attitudes in people with a mild learning disability – the effects of a ‘sensible drinking’ group

Alcohol-related knowledge and attitudes in people with a mild learning disability, who were either living, or being prepared to live, in relatively independent conditions in the community, were assessed through a structured interview format. Compared with non-learning-disabled teenagers, adults and a hospitalized patient sample, alcohol-related knowledge in the people with a learning disability was found to be significantly poorer, alcohol was reported as having particularly negative effects and susceptibility to social pressure to drink alcohol was greater. A ‘sensible drinking’ group, taking a social skills and influences approach to alcohol education, was conducted with a subgroup of the individuals with a learning disability. The group format and methods, including in vivo sessions in a public house, are described. Follow-up evaluations suggested some significant positive changes in knowledge, attitudes and sensible drinking skills. It is concluded that this population, which is increasingly living, or being moved into, independent conditions in the community, is at least as vulnerable to social influences on alcohol use and abuse as are young people. As with young people, the usefulness of making available such alcohol-education programmes as described in this study, is discussed.     

Television sex roles in the 1980s: Do viewers' sex and sex role orientation change the picture?

This study investigated viewer perceptions of female and male television characters as a result of viewer sex and sex role orientation. Young adult viewers (N=677) rated television characters and themselves using the Personal Attributes Questionnaire (PAQ). Viewers were classified as feminine, masculine, androgynous, or undifferentiated in their PAQ orientations. The television characters were four men and four women who shared the lead and a working relationship on crime action shows. Results indicated that viewers rated all the male characters as stereotypical masculine, but only one female character as stereotypical feminine. Viewer sex and sex role orientations did affect ratings. Viewer sex had a greater impact on the ratings of female characters than on the ratings of male characters. Female viewers tended to rate female characters as higher in instrumental and masculine traits than male viewers did. Results based on sex role orientation of the viewer were inconsistent across characters, but in general, undifferentiated viewers rated both male and female characters as low in expressive and instrumental traits compared to how androgynous viewers rated them. Further, a masculine sex role orientation appeared to block perception of expressive traits in both male and female characters.This research was supported in part by a University of Akron faculty research grant.     

Posterior parietal cortex as part of a neural network for directed attention in rats

A rodent model of directed attention has been developed based upon behavioral analysis of contralateral neglect, pharmacological manipulations, and anatomical analysis of neural circuitry. In each of these three domains the rodent model exhibits striking similarities to humans. We hypothesize that there is a specific thalamo-cortical-basal ganglia network that subserves spatial attentional functions. Key components of this network are medial agranular and posterior parietal cortex, dorsocentral striatum, and the lateral posterior thalamic nucleus. Several issues need to be addressed before we can hope to realistically understand or model the functions of this network. Among these are the roles of medial versus lateral posterior parietal cortex; cholinergic mechanisms in attention; interhemispheric interactions; the role of synchronous firing at the cortical, striatal, and thalamic levels; interactions between cortical and thalamic projections to the striatum; interactions between cortical and nigral inputs to the thalamus; the role of collicular inputs to the lateral posterior thalamic nucleus; the role of cerebral cortex versus superior colliculus in driving the motor output expressed as orienting behavior during directed attention; the extent to which the circuitry we describe for directed attention also plays a role in other forms of attention.
