Adult Attachment in Children Raised by Parents with Schizophrenia

Maternal schizophrenia is known to have an adverse effect on the quality of mother–infant interaction; and children of parents with severe mental illness run a higher risk of poor mental health and social outcomes. Hence, children raised by a parent with schizophrenia may be less likely to attain secure attachment, although there is less evidence so far to support this. Moreover, there is a lack of research in this field that focusses on the needs and experiences, the strengths and vulnerabilities, of the children themselves. Qualitative methods are thus needed to generate new insights and hypotheses. The present study uses semi-structured interviews with 23 adults who, as children, were raised with a parent who experienced schizophrenia. This reveals a range of attachment problems, resulting in difficulties in forming secure adult relationships. Problems with trust and intimacy were found to be common.     

The Credentialing Problems of Foreign Trained Personnel from Asia and Africa Intending to Make their Home in Canada: A Social Psychological Perspective

This study examined the experiences of a sample of skilled immigrants to Canada from Asia and Africa who were currently experiencing credentialing problems (N?=?180). Most respondents had advanced postsecondary training and a job requiring a high level of skill prior to emigrating, but many were unable to obtain equivalent work in Canada. In reaction, they took work for which they were overqualified, volunteered, had their qualifications assessed, and upgraded their training. Most respondents were surprised and upset that it was so difficult for them to obtain a suitable job in their profession, and many felt that immigrants were discriminated against by Canadian employers. The policy implications of this “brain waste” are discussed.     

From marine ecology to crime analysis: Improving the detection of serial sexual offences using a taxonomic similarity measure

Jaccard has been the choice similarity metric in ecology and forensic psychology for comparison of sites or offences, by species or behaviour. This paper applies a more powerful hierarchical measure—taxonomic similarity (Δ_s), recently developed in marine ecology—to the task of behaviourally linking serial crime. Forensic case linkage attempts to identify behaviourally similar offences committed by the same unknown perpetrator (called linked offences). Δ_s considers progressively higher‐level taxa, such that two sites show some similarity even without shared species. We apply this index by analysing 55 specific offence behaviours classified hierarchically. The behaviours are taken from 16 sexual offences by seven juveniles where each offender committed two or more offences. We demonstrate that both Jaccard and Δ_s show linked offences to be significantly more similar than unlinked offences. With up to 20% of the specific behaviours removed in simulations, Δ_s is equally or more effective at distinguishing linked offences than where Jaccard uses a full data set. Moreover, Δ_s retains significant difference between linked and unlinked pairs, with up to 50% of the specific behaviours removed. As police decision‐making often depends upon incomplete data, Δ_s has clear advantages and its application may extend to other crime types. Copyright © 2007 John Wiley & Sons, Ltd.     

Animal innovation defined and operationalized

Innovation is a key component of most definitions of culture and intelligence. Additionally, innovations may affect a species' ecology and evolution. Nonetheless, conceptual and empirical work on innovation has only recently begun. In particular, largely because the existing operational definition (first occurrence in a population) requires long-term studies of populations, there has been no systematic study of innovation in wild animals. To facilitate such study, we have produced a new definition of innovation: Innovation is the process that generates in an individual a novel learned behavior that is not simply a consequence of social learning or environmental induction. Using this definition, we propose a new operational approach for distinguishing innovations in the field. The operational criteria employ information from the following sources: (1) the behavior's geographic and local prevalence and individual frequency; (2) properties of the behavior, such as the social role of the behavior, the context in which the behavior is exhibited, and its similarity to other behaviors; (3) changes in the occurrence of the behavior over time; and (4) knowledge of spontaneous or experimentally induced behavior in captivity. These criteria do not require long-term studies at a single site, but information from multiple populations of a species will generally be needed. These criteria are systematized into a dichotomous key that can be used to assess whether a behavior observed in the field is likely to be an innovation.     

Modeling individual differences in working memory performance: a source activation account

Working memory resources are needed for processing and maintenance of information during cognitive tasks. Many models have been developed to capture the effects of limited working memory resources on performance. However, most of these models do not account for the finding that different individuals show different sensitivities to working memory demands, and none of the models predicts individual subjects' patterns of performance. We propose a computational model that accounts for differences in working memory capacity in terms of a quantity called source activation , which is used to maintain goal-relevant information in an available state. We apply this model to capture the working memory effects of individual subjects at a fine level of detail across two experiments. This, we argue, strengthens the interpretation of source activation as working memory capacity.     

Use of the Sleep Assessment Device (Kelley and Lichstein, 1980) to validate insomniacs' self-report of sleep pattern

A comparison is presented of insomniacs' self-reported sleep pattern and objectively monitored sleep using the Sleep Assessment Device (SAD; Kelley & Lichstein, 1980). Analysis of 110 subject nights revealed modest but significant subjective overestimates of both sleep latency and sleep duration which were accounted for by the demands of the task (i.e., longer time periods are harder to estimate accurately). Correlations between self-report and SAD measures were, however, consistently high, suggesting that self-report may be a valid index of sleep disturbance. Results are discussed with reference to the clinician's task in evaluating sleep complaints.This research stury was supported by a grant from the Research Fund of Lanarkshire Health Board, Scotland.     

Performance of british university psychology departments as measured by number of publications in BPS journals

The aim of this investigation was to gauge the comparative research performance of university departments of psychology in Britain. The performance indicator was the number of publications per departmental staff member in the journals of the British Psychological Society (BPS) during the seven-year period 1983–1989. The contents of these journals were thoroughly searched, and articles written by members of university psychology departments in Britain were counted. The number of publications of each psychology department was divided by the size of the department in the corresponding year and the resulting annual figures were summed to determine the number of publications in BPS journals per departmental staff member over the seven-year period. These research performance figures correlated significantly with an earlier measure of departmental research performance based on publications in the seven European psychological journals with the highest citations per published article and with recent performance indicators based on other criteria     

Competitive Climates,Athletic Skill,and Children's Status in After-School Recreational Sports Programs

Relationships among competition, athletic skill, and social relationships among children have received considerable attention from social psychologists and have also sparked considerable public debate. Most studies of these relationships have concentrated on sports programs involving upper elementary or older boys. This field work study examined these relationships in three after-school recreation programs for children ages 5 to 8. Although all programs professed to stress skills development over competition, teams act varied substantially in competitive climates. Competitive environments heightened the tendency for athletic skill to function as a generalized status element in peer networks. After-school sports programs contributed to the reproduction of athletic skill as a basis of peer status, even for young children.     

Commentary on high-performance computing and human vision II: Virtual reality and eyeball tracking

Visualization of scientific data that are not normally visible can be greatly enhanced by understanding human visual perception. Mars the Movie illustrated the use of stereo resolution for producing realistic vistas of the Mars surface. The real-time recording and analysis of eyeball-tracking data is another example of human vision research which benefits from high-performance computing. Currently the bottleneck is not in the hardware but in the available software to transform data efficiently.
