Can the Edinburgh Risk of Repetition Scale Predict Repetition of Deliberate Self‐poisoning in an Australian Clinical Setting?

This study tested the ability of the Edinburgh Risk of Repetition Scale (ERRS) to identify patients at high risk for repeat deliberate self-poisoning (DSP). Consecutive DSP patients (N= 1,317) over a 3-year period were followed-up for 12 months. A statistically significant relationship between ERRS scores and repetition was observed; however, sensitivity and specificity were low. Logistic regression analysis revealed only "previous parasuicide" contributed significantly to repetition. The ERRS had limited value in identifying patients at high risk of repeat DSP in this clinical population.     

Neuropsychological disorders indicative of postresuscitation encephalopaty in rats

The aim of this research was to study the effect of 12-minute clinical death on innate and acquired behavior, biogenic amine concentration, and the composition and quantity of neural populations in specific brain regions of white rats. The study shows that in animals during the postresuscitation period with formal restoration of neurological status, there are changes in emotional reactivity, orientation-exploration reactions, impairment of learning and memory, decrease in exercise tolerance and pain sensitivity. These processes are accompanied by alterations in serotonin and norepinephrine levels in the frontal cerebral cortex, dopamine and serotonin levels in the striatum, certain biochemical indices in blood plasma and neural loss in the CA1 sector of the hippocampus and lateral portions of the cerebellum.     

Distinguishing Caregiver Strain from Psychological Distress: Modeling the Relationships Among Child, Family, and Caregiver Variables

Although both have been used in studies of the impact of mental illness on the family, the constructs of caregiver strain (often referred to as burden of care) and psychological distress have not been clearly distinguished. The vagueness surrounding these constructs, and the lack of a cohesive conceptual framework for understanding how they relate, leads to contradictory interpretations of results. This compromises the building of the knowledge base needed to develop and evaluate interventions to support families as they struggle to meet the needs of their children with emotional and behavioral challenges. We utilized the ABCX Model as a framework for understanding caregiver strain and its relationship to psychological distress. Structural equations modeling was used to test the hypothesized relationship between caregiver strain and psychological distress, as well as the role of key child and family variables. These included child symptoms, stressful life events, social support, family functioning, and material resources. Our findings indicated that caregiver strain and psychological distress, although related, have distinct correlates and different implications in the family context.

Values,Susceptibility to Normative Influence,and Attribute Importance Weights: A Nomological Analysis

It is argued that the construct of individual susceptibility to normative influence (SNI) needs to be put into a wider nomological framework, with antecedents and consequences. Based on prior literature, a causal sequence is hypothesized in which values are antecedent to SNI, which itself shapes the importance placed by the individual on different attributes. It is further suggested that the relation between values and SNI is strongest for “external” values, and that high SNI leads to greater importance for attributes that provide “socially visible” benefits. Data from a national field survey (N= 663) on consumer preferences are analyzed to test these hypotheses, using confirmatory factor analysis via LISREL 8.30 (Jöreskog & Sörbom, 1993). The analysis finds support for most of the hypothesized structural relations.     

The influence of task requirements on priming in object decision and matching

We argue that task requirements can be the determinant in generating different results in studies on visual object recognition. We investigated priming for novel visual objects in three implicit memory tasks. A study-test design was employed in which participants first viewed line drawings of unfamiliar objects and later made different decisions about structural aspects of the objects. Priming for both symmetric and asymmetric possible objects was observed in a task requiring a judgment of structural possibility. However, when the task was changed to one requiring a judgment of structural symmetry, only symmetric possible objects showed priming. Finally, in a matching task in which participants made a same-different judgment, only symmetric possible objects exhibited priming. These results suggest that an understanding of object representation will be most fruitful if it is based on careful analyses of both the task demands and their interaction(s) with encoding and retrieval processes.     

Place learning in virtual space III: Investigation of spatial navigation training procedures and their application to fMRI and clinical neuropsychology

This paper describes the utilization of a desktop virtual environment task, the Computer-Generated (C-G) Arena, in the study of human spatial navigation. First, four experiments examined the efficacy of various training procedures in the C-G Arena. In Experiment 1, participants efficiently located a hidden target after only observing the virtual environment from a fixed position (placement learning). In Experiment 2, participants efficiently located a hidden target after only observing an experimenter search the virtual environment (observational learning). In Experiment 3, participants failed to display alatent learning effect in the virtual environment. In Experiment 4, all training procedures effectively taught participants the layout of the virtual environment, but the observational learning procedure most effectivelytaught participants the location of a hidden target within the environment. Finally, two experiments demonstrated the application of C-G Arena procedures to neuroimaging (Experiment 5) and neuropsychological (Experiment 6) investigations of human spatial navigation.     

Constructions of work stress and coping in a female- and a male-dominated department

In the present study the nature of stress and coping was investigated and considered as socially constructed. Thirty small group interviews were performed using the Critical Incident Technique in one female- and one male-dominated customer service department of a telecom company. The main themes about stress among both women and men were often expressed as collective phenomena and were connected to the organizational change and downsizing process, problems when carrying out the work and lack of autonomy. However, a striking difference between female and male interviews was found in the way that women to a greater extent expressed lack of autonomy and their working situation was described as strictly regulated. The findings illustrate that a traditional gender difference regarding autonomy could be found when comparing a female- and a male-dominated department even though they were performing the same type of job. Both women and men portrayed coping as a mixture of collective and individual strategies. They often mentioned collective acceptance, resignation and hardening. There is a need for further research about women and men at work, taking into consideration the interpersonal context and the collective nature of stress and coping.     

Opinion‐based group membership as a predictor of commitment to political action

Research on group identification has shown it to be a surprisingly weak predictor of intentions to take large‐scale social action. The weak links may exist because researchers have not always examined identification with the type of group that is most relevant for predicting action. Our focus in two studies (one in Romania and one in Australia, both Ns = 101) was on opinion‐based groups (i.e. groups formed around shared opinions). We found that social identification with opinion‐based groups was an excellent predictor of political behavioural intentions, particularly when items measuring identity certainty were included. The results provide clear evidence of the role of social identity constructs for predicting commitment to social action and complement analyses of politicised collective identity and crowd behaviour.
