Central executive involvement in children's spatial memory

Previous research with adults found that spatial short-term and working memory tasks impose similar demands on executive resources. We administered spatial short-term and working memory tasks to 8- and 11-year-olds in three separate experiments. In Experiments 1 and 2 an executive suppression task (random number generation) was found to impair performances on a short-term memory task (Corsi blocks), a working memory task (letter rotation), and a spatial visualisation task (paper folding). In Experiment 3 an articulatory suppression task only impaired performance on the working memory task. These results suggest that short-term and working memory performances are dependent on executive resources. The degree to which the short-term memory task was dependent on executive resources was expected to be related to the amount of experience children have had with such tasks. Yet we found no significant age-related suppression effects. This was attributed to differences in employment of cognitive strategies by the older children.     

Saints and Sinners: Training Papua New Guinean (PNG) Christian Clergy to Respond to HIV and AIDS Using a Model of Care

Papua New Guinea has experienced a growing HIV/AIDS epidemic. The Christian Churches have played a vital role in responding to HIV, through community support, encouragement and social change. Strong, effective Church leadership can help create safe environments of care and support for those infected and for prevention of HIV. Method A series of trainings in capacity development for clergy were undertaken by the National AIDS Council Secretariat (NACS)/National HIV/AIDS Support Project (NHASP). Results A model “Church’s Response to HIV and AIDS in a Care Continuum” was developed to assist the training. This paper discusses the model and the lessons learned.

Discussion of the Articles by Goodman,Schwartz and Aronson Panel Entitled “Are the Times Changing”

The authors ask what analysis would be like if Freud had started as a child analyst. They examine each of the presentations and suggest that each illustrates child techniques that can usefully be applied to work with adults with the goal of a unified “life cycle analysis.”     

Thalamic pathways for active vision

Active vision requires the integration of information coming from the retina with that generated internally within the brain, especially by saccadic eye movements. Just as visual information reaches cortex via the lateral geniculate nucleus of the thalamus, this internal information reaches the cerebral cortex through other higher-order nuclei of the thalamus. This review summarizes recent work on four of these thalamic nuclei. The first two pathways convey internal information about upcoming saccades (a corollary discharge) and probably contribute to the neuronal mechanisms that underlie stable visual perception. The second two pathways might contribute to the neuronal mechanisms underlying visual spatial attention in cortex and in the thalamus itself.     

Mind the gap: Increasing associations between the self and Blacks with approach behaviors

Although perceived differences between outgroup social categories and the self are often cited as a major contributor to prejudice and intergroup tension, surprisingly few studies have examined ways to improve associations between the self and racial outgroups. The present research investigated one strategy to increase these associations-approach training. Specifically, 3 studies investigated the impact of training participants to conceptually approach Blacks on 3 separate measures: 2 response latency measures indexing the strength of association between the self and Blacks and a psychophysiological measure indexing brain activity in response to Blacks in the context of the self. A fourth study examined the link between earlier research on the impact of approach training on implicit prejudice against Blacks and the current results related to self-Black associations. Together, these findings provided consistent evidence that training in approaching Blacks increases associations between the self and Blacks that in turn reduce implicit prejudice against Blacks.     

Pasifika in the news: the portrayal of Pacific peoples in the New Zealand press

Pacific Islanders have faced discrimination in New Zealand particularly since the 1960s when communities began to be transplanted from their home nations to Aotearoa as cheap immigrant labour. Subsequently, the New Zealand vernacular has contained references to Pacific Islanders as ‘overstayers’, ‘coconuts’, ‘bungas’ and ‘fresh off the boat’ [FOB]. However, the legacy of a domineering relationship between the Palagi 1 majority group and Pacific minorities 2 that is captured by such derogatory terms is still evident in public forums such as the media. Using a quantitative content and qualitative narrative analysis, this paper documents portrayals of Pacific Islanders in New Zealand print media reports (n = 65) published over a 3 month period. Findings reveal that Pacific people are predominantly portrayed as unmotivated, unhealthy and criminal others who are overly dependent on Palagi support. We consider this offered pacific identity formation with that implied for Palagi, which is active, independent, competent and caring. Issues in coverage are discussed in relation to how Pacific Islanders are encouraged to see themselves, and the health and social consequences of dominant practices in press coverage. We offer some suggestions as to how more equitable representations of Pacific people could be fostered in news media. Copyright © 2006 John Wiley & Sons, Ltd.     

A free and simple computerized screening test for visual field defects

About 30–40% of stroke patients suffer from visual field defects following injury. These can interfere with the standard neuropsychological assessment and complicate the interpretation of tests that use visual materials. However, information about the integrity of a patient's central visual field is often unavailable. We, therefore, designed a screening tool, the computerized visual field test (c‐VFT), specifically targeted at providing easily available, but rough, information about patients' central visual field. c‐VFT was tested in two samples of stroke patients. Eleven patients were tested on c‐VFT and on the Esterman test. Five patients were tested on c‐VFT and the Humphrey Visual Field Analyzer (HFA), central 10‐2. Criterion validity of the c‐VFT was investigated by calculating quadrantwise intraclass correlation for both comparisons. For the HFA comparison, we also calculated point‐to‐point intraclass correlation, sensitivity, and specificity. Analyses revealed moderately good correspondence between c‐VFT and the Esterman test, and between c‐VFT and HFA 10‐2, respectively. When looking specifically at test points within one degree of visual angle apart in the two tests, intraclass correlation increased. For these points, the sensitivity of c‐VFT was 0.89 and specificity was 0.97. While the c‐VFT is not designed to be diagnostic nor to replace the detailed visual field analysis, this study shows that it provides a reasonable screening of the central visual field. The test can easily be used and will be made freely available to neuropsychological clinicians and researchers.
