The effect of occupational exposure to manganese dust and fume on neuropsychological functioning in Australian smelter workers.

Chronic low-level occupational exposure to manganese (Mn) is reportedly associated with the development of Parkinsonian-like symptoms. In a study of 143 manganese smelter workers, inhalable Mn exposure was associated with lower performances on the Digit Symbol Coding and Stroop tests; respirable Mn exposure was associated with improved Digit Symbol Coding test performance and reduced performance on the Trail Making (Part A), Matrix Reasoning, and Stroop tests. While these relationships reached statistical significance, the magnitude of these effects was significantly smaller than the standard error of measurement of the neuropsychological tests, indicating that these differences are not of clinical significance.

Where should the balance be between “scientist” and “practitioner” in Australian undergraduate psychology?

Abstract The scientist–practitioner model of training in psychology has been widely influential in the development of undergraduate curricula in Australia. The model had its origins in post-war America and has formed the basis for accreditation of psychology courses in Australia since the late 1970s. Recently a reconsideration of the model in Australian undergraduate psychology was argued for, suggesting that the absence of significant practical skills development in most curricula is detrimental to the disciplines graduates and their employers. The authors agree that the need for some practical skills development in undergraduate curricula is becoming increasingly important for psychology. Many of the exemplars of curriculum revision provided, however, are impractical and are unlikely to make significant contributions to Australian programs. There is an urgent need to consider the graduate attributes desired for 3-year and 4-year trained psychology graduates who will go on to employment without completi...

CEQ and GDS outcomes in psychology, 1994-2003

This study was undertaken to develop and evaluate the efficacy of an early intervention for children who had been injured in an accident. The aim of the intervention was to prevent the development of longterm psychological consequences. Brochures were developed for children, adolescents, and their parents. These brochures detailed common responses to trauma (and normalized such responses), and suggestions for minimizing any post-trauma distress. Participants were children aged 7-15 admitted to hospital for traumatic injury. The intervention was delivered to one of two hospitals, within 72 hours of the trauma. 103 children and parents participated in the study. The parents and children completed structured interviews and questionnaires 2 weeks, 4-6 weeks and 6 months post-trauma. Outcome analyses also indicated that the intervention reduced parental distress at 4-6 weeks post-trauma. The intervention did not impact significantly on child adjustment over this time period. Results of the 6 month follow-up suggested that the intervention resulted in an amelioration of child anxiety from one to six months post-trauma, whereas the controls exhibited an increase in anxiety over this time period. Overall, it was concluded that the early intervention is a simple, practical, and cost-effective method of reducing child and parent distress post-trauma.

Using Interviews to Predict the Success of Teacher‐education Students

Abstract In November 1987, the School of Education at the University of Tasmania at Launceston (then the Tasmanian State Institute of Technology) commenced a programme of pre‐entry assessment of BEd applicants with a view to conducting an ongoing research programme aimed at improving the quality of trainee teachers. Pre‐entry data gathering included English and mathematics skills, learning style, Higher School Certificate (HSC) aggregate scores and interview assessments of each applicant by a panel of at least two academic staff of the School. This paper reports findings from the interview data gathered on students who entered the BEd programme in 1989. In particular, the evidence from this cohort of students suggests that interview ratings by academic staff are successful predictors of future practice‐teaching performance, whereas HSC aggregate scores are not at all predictive. In addition to this finding, the data indicate that staff interview assessments are only marginally weaker than HSC aggregate sc...
