Learning and motivation: Computer simulations of the Rescorla-Wagner,Solomon-Corbit,and Schull models

A suite of programs is described for simulating the Rescorla-Wagner (1972) model of associative learning, the Solomon and Corbit (1974) opponent-process theory, and Schull’s (1979) extension of the latter. The programs are written for the Commodore 64 computer.     

Developing Work-Related Education on Alcohol and Drugs

The development of a pack of materials for use at the intersection of youth training and health and social education is described. The resulting pack - WREAD (Work Related Education on Alcohol and Drugs) - is designed to be used in several milieux, including the Youth Training Scheme and associated developments, the new college-based pre-vocational education courses and, in the longer term, schools and other social education settings. The paper describes the context, the development of a draft, a consultation exercise with people working in and around YTS who were asked to comment on the draft, conversations with young people, and the revision and publication of the materials.     

Childhood fantasy play relates to adult socio-emotional competence

Childhood fantasy play and creation of imaginary companions are thought to confer socio-emotional benefits in children, but little is known about how they relate to socio-emotional competence in adulthood. A total of 341 adults (81 males) aged 18 and above (M = 31.47, SD = 12.62) completed an online survey examining their fantasy play as a child, their childhood imaginary companion status, and their adult socio-emotional competence. Adults who reported higher levels of childhood fantasy play were found to be significantly more prosocial, empathetic, and emotionally intelligent than their counterparts after controlling for demographic factors. Recall of a childhood imaginary companion, however, was significantly related only to higher scores for perspective-taking and did not explain unique variance in any adult competence measure. Findings suggest that engagement in fantasy play during childhood may be a precursor to later socio-emotional competence, while benefits previously associated with imaginary companions specifically may not extend into adulthood.     

The impact of short-term counselling on general health questionnaire scores

An evaluation was conducted of short-term counselling in a higher education setting. The main objective was to measure client scores on a shortened version of the General Health Questionnaire (GHQ-12) pre- and post- counselling. Forty-five matched pairs of GHQ-12 scores were compared. There was a highly significant reduction in scores post-counselling. The evidence suggests that the 'great pretender' evaluation can be challenged using standard quantitative measures such as the GHQ-12. It is concluded that counselling in higher education may be addressing long-standing distress in members of the student population.     

Borderline personality features predict alcohol use problems

This study assessed the relation between BPD features and problems associated with alcohol use 2 years later in young adults. Approximately 5,000 nonclinical young adults were screened for BPD features, and two cohorts of participants completed the laboratory phase of the study at Time 1 (total N = 421) and then again 2 years later at Time 2 (total N = 356). Measures included self-report and interview-based assessments of personality disorders, psychopathology in biological parents, Axis I psychopathology, and alcohol use problems. BPD features were found to significantly predict alcohol use problems 2 years later after controlling for parents' substance use disorders, Axis I psycho-pathology (including alcohol abuse/dependence), and non-BPD personality disorders. In addition, the BPD subscale that assesses impulsivity was found to be significantly associated with alcohol use problems once all predictors were entered into the model.     

Predicting traumatic stress using emotional intelligence

The study investigated whether emotional intelligence (EI) can predict how individuals respond to traumatic experiences. A random sample of 414 participants (181 male, 233 female) were administered a measure of EI along with the Impact of Event Scale--revised [IES-R; Weiss, D. S. & Marmar, C. R. (1997). The Impact of Events Scale--revised. In J.P. Wilson & T.M. Keane (Eds.), Assessing psychological trauma and PTSD (pp. 399-411). New York: Guilford Press], and the monitoring and blunting questionnaire [MBQ, Anxiety Stress Coping 7 (1994) 53]. The results showed that participants with higher NEIS scores report fewer psychological symptoms relating to their traumatic experiences, that monitors are more likely to have higher NEIS scores than blunters. Traumatic events had a greater impact on females than males, and males had higher EI than females. The implications of these findings for using EI as a predictor for individuals who may experience traumatic stress are discussed.     

Borderline personality disorder features predict negative outcomes 2 years later

In a sample of 351 young adults, the authors assessed whether borderline personality disorder (BPD) features prospectively predicted negative outcomes (poorer academic achievement and social maladjustment) over the subsequent 2 years, over and above gender and both Axis I and Axis II psychopathology. Borderline traits were significantly related to these outcomes, with impulsivity and affective instability the most highly associated. The present findings suggest that the impulsivity and affective instability associated with BPD leads to impairment in relating well with others, in meeting social role obligations, and in academic or occupational achievement. Therefore, these may be especially important features to target in interventions for BPD.     

Influence of spatial environment on maze learning in an African mole-rat

In subterranean species where excavation is energetically expensive, efficient spatial navigation is vital to reducing the costs of locating important resources such as food and mates. While spatial navigational ability is positively correlated with sociality in subterranean mammals, we have a less clear understanding of the role of habitat complexity on navigational ability. We tested spatial navigational ability and memory in 12-18-month captive Natal mole-rats (Cryptomys hottentotus natalensis) maintained in a simple environment with no environmental enrichment and newly captured wild individuals from natural, complex burrow systems. In maze trials, mole-rats captured freshly from the wild made significantly fewer navigational errors, were more likely to successfully navigate the maze, travelled shorter distances and as a consequence, completed the maze in less time. Male mole-rats from both experimental treatments were more likely to complete the maze than females. Memory retention of the maze was tested on day two, seven, 30 and 60, respectively. The results were variable, although both groups showed a significant memory retention 60?days after testing. Our results highlight the potential importance of the environment (microhabitat complexity) on spatial cognitive performance in mole-rats.
