Manual asymmetry in weight discrimination: hand or spatial-field advantage?

Sixty subjects who were either left-handed or right-handed performed one-handed weight discrimination using their left and right hands in the left and right spatial fields. Differential thresholds, for the left and right hands of both left-handed and right-handed subjects, were found to be lower in the spatial field contralateral to the ear which proved superior in a dichotic listening test. It is concluded that manual asymmetry for weight discrimination results primarily from the mapping of sensorimotor events in the spatial fields onto contralateral cerebral cortex, with an advantage in the spatial field contralateral to the nonlanguage cerebral hemisphere.     

Correlations between glucose metabolic rates in brain regions of healthy male adults at rest and during language stimulation

This study examines the effect of different behavioral conditions on patterns of correlation between regional cerebral metabolic rates for glucose. Cerebral glucose metabolism was determined with positron emission tomography and (11C)-deoxyglucose in 29 normal subjects between the ages of 23 and 55. Seventeen subjects were studied in an unstimulated (resting) condition and 12 subjects during a phoneme monitoring language stimulation. Partial correlation coefficients, controlling for whole brain glucose metabolism, were calculated for pairs of metabolic rates in 14 cortical and 2 subcortical regions. Both stimulated and unstimulated subjects showed statistically significant correlations between left and right hemisphere homologs. The stimulated subjects also showed significant within-hemisphere correlations between left but not right hemisphere regions. These included left perisylvian regions classically associated with language functions (left inferior frontal, left superior temporal and left transverse temporal cortical regions) as well as other regions. Significant correlations between left regions and a right superior temporal region were also found. In general, these findings show a pattern of cross-hemisphere symmetry at rest and of hemisphere asymmetry during stimulation. Moreover, the asymmetry observed during stimulation appears to be superimposed upon a pattern of cross-hemisphere symmetry similar to that observed in the unstimulated state.     

Attention,autonomic arousal,and personality in behaviorally disordered children

This study assessed the construct validity of the Revised Behavior Problem Checklist (RBPC) by measuring attention, autonomie arousal, and personality in 40 behaviorally disordered children aged 7 to 15 years. Conduct Disorder and Socialized Aggression subscales were characterized by high Psychoticism, Impulsivity, and Lie personality scores, by lower heart rate levels, and by more errors on a continuous performance reaction-time task. Conversely, Attention Problems, Anxiety Withdrawal, and Motor Excess were characterized by greater variability in reaction times. Conduct Disorder alone was related to an external locus of control, while only Attention Problems was characterized by low scores on the WISC Freedom from Distraction factor. These differential relationships suggest (a) support for the construct validity of the RBPC, (b) that antisocial behavior and hyperactivity/attention deficits are dissociated disorders, and (c) that hyperactivity/attention deficits may be characterized by fluctuations in the allocation of attentional resources rather than a core structural deficit in attention.     

Human Resource Management Group,University of Nottingham,UK

In a new series of regular reports, research groups active in personnel psychology from a number of countries will present a briefing on work-in-progress. In the first in this series, the HRM Group at the Department of Psychology, University of Nottingham, describe their ongoing work into organization change and training validation, employee socialization, computer-based testing, and personality test construction and assessment centre validation.     

If This Is My Body … : A Defence of the Doctrine of Doing and Allowing

I defend the Doctrine of Doing and Allowing: the claim that doing harm is harder to justify than merely allowing harm. A thing does not genuinely belong to a person unless he has special authority over it. The Doctrine of Doing and Allowing protects us against harmful imposition – against the actions or needs of another intruding on what is ours. This protection is necessary for something to genuinely belong to a person. The opponent of the Doctrine must claim that nothing genuinely belongs to a person, even his own body.     

Investigating the role of E-contact and self-disclosure on improving Turkish-Kurdish interethnic relations

While recent research has started to pay more attention to the role of contact strategies on promoting intergroup harmony between Turkish and Kurdish communities, the effectiveness of a novel form of indirect contact strategy, E-contact—where participants engage in a cooperative and structured online interaction with an individual from the outgroup—has not yet been tested. Across two studies (N_{Study 1} = 110, N_{Study 2} = 176), we investigated the effects of E-contact among Turks on promoting positive attitudes and behavioral tendencies toward Kurds, testing outgroup trust and intergroup anxiety as mediators and incorporating a distinction between lower and higher self-disclosure conditions. As expected, E-contact led to more positive outgroup attitudes, as well as greater approach tendencies and decreased avoidance tendencies through increased outgroup trust (Studies 1 and 2) and reduced intergroup anxiety (Study 2). Study 2 also found that E-contact produced lower perceived interethnic conflict through increased outgroup trust. While both lower and higher personal disclosure conditions provided similar effects in the two studies, E-contact with heightened self-disclosure was especially effective at promoting more positive outgroup attitudes and reducing avoidance tendencies. Findings highlight potential benefits of using E-contact as a prejudice-reduction strategy in conflict settings.     

Pathways to prejudice and outgroup hostility: Group alignment and intergroup conflict among football fans

How do different forms of group alignment influence our attitudes toward outgroups? To answer this, the current fieldwork study explored how identification and identity fusion differentially impact outgroup anxiety, prejudice, and hostility toward rival football fan supporter groups in Australia. The community participants (N = 100) were members of two active fan groups who had experienced a history of intergroup tensions. The findings from the full path model confirmed that the predictor group alignment variables of identification and fusion were correlated, and the two outcome variables of outgroup prejudice and hostility were correlated, as predicted. The findings also revealed that fusion with one's club predicted outgroup hostility, but not prejudice, whereas identification with one's club predicted outgroup prejudice, but not hostility. Additionally, outgroup anxiety was found to significantly mediate the relationship between ingroup identification and outgroup prejudice, whereas a similar relationship was not found for fusion. These findings highlight the differential impact of group alignment (i.e., identification and identity fusion) on social constructs of outgroup anxiety, prejudice, and hostility. Empirically, this is the first study to demonstrate the workings of these distinct group alignment pathways in an applied setting involving hard-core football fans. We discuss the broader implications of these findings for a fuller understanding of the drivers of intergroup tensions and conflict.
