The aim of this study was to examine whether street gang membership, psychological factors, and social factors such as preprison experiences could predict young offenders' involvement in prison gang activity. Data were collected via individual interviews with 188 young offenders held in a Young Offenders Institution in the United Kingdom. Results showed that psychological factors such as the va...

The relationship between right-wing ideological attitudes and psychological well-being has been intensively studied. Although some studies supported the hypothesis that right-wing attitudes are negatively related with well-being, other research yielded positive or nonsignificant relationships. We conducted a meta-analysis (total samples = 97, total N = 69,221) of measures of well-being, includi...

Prior research has established a link between Social Dominance Orientation (SDO), empathy, and generalized measures of prejudice. Whether empathy functions as a mediator for more specific forms of prejudice has not been studied. Furthermore, alienation and its role in predicting prejudice have been given little attention in the literature. Our results found that empathy functioned as a mediator...

Ocular dominance columns were demonstrated in the visual cortex of kittens by [3H]-2-deoxyglucose autoradiography after monocular stimulation with patterns of different orientations. On horizontal sections through area 17, a pattern of periodic labelling extended throughout the entire thickness of the cortex. Three days of monocular deprivation disrupted that pattern. The ocular dominance colum...

A push-pull training protocol is applied to reduce sensory eye dominance in the foveal region. The training protocol consists of cueing the weak eye to force it to become dominant while the strong eye is suppressed when a pair of dichoptic orthogonal grating stimulus is subsequently presented to it (Ooi & He, 1999). We trained with four pairs of dichoptic orthogonal gratings (0°/90°, 90°/0°, 45...

It has been widely accepted that ocular dominance in the responses of visual cortical neurons can change depending on visual experience in a postnatal period. However, experience-dependent plasticity for orientation selectivity, which is another important response property of visual cortical neurons, is not yet fully understood. To address this issue, using intrinsic signal imaging and two-phot...

Throughout vertebrate phylogeny, testosterone has motivated animals to obtain and maintain social dominance-a fact suggesting that unconscious primordial brain mechanisms are involved in social dominance. In humans, however, the prevailing view is that the neocortex is in control of primordial drives, and testosterone is thought to promote social dominance via conscious feelings of superiority,...
