Cross-national evidences of a school-based universal programme for promoting prosocial behaviours in peer interactions: Main theoretical communalities and local unicity

The purpose of this study was to evaluate the role of prosocial behaviour against aggression in a school-based universal intervention adapted in two different (non-Western) countries, Colombia and Chile. Using a randomised pretest–post-test design (and controlling for participants' gender and parents' level of education), current results highlighted different effects of a similar programme in both sites. First, the school-based universal programme designed for promoting prosocial behaviours in the peer context obtained a positive cross-national effect on prosocial behaviour rated by three informants (i.e. self, peer and teacher reports). In Colombia, this effect was moderated by the initial level of prosociality of the participants and their level of education. Mediational two-wave model corroborated that the improvement on prosocial behaviours in both countries (moderated in the case of Colombia) predicted significantly lower level of physical aggression. Characteristics of the implementation considering different cultural and historical backgrounds were discussed.     

Integrated Schooling and Religious Tolerance in Northern Ireland

The design of educational institutions has long been seen as a key element in determining social divisions. This article examines the long-term impact of separate and integrated education on relations between the two religious communities (Catholics and Protestants) in Northern Ireland. Using a large-scale survey, the results suggest that in comparison to their previously separate counterparts, individuals who attended an integrated school are more likely to be understanding and respectful of the culture and traditions of others. The finding holds even after a range of background characteristics are taken into account. The results have implications for the role of segregated educational institutions in ameliorating religious, ethnic or racial division in other post-conflict societies. The Northern Ireland evidence suggests that a segregated school system rather than ameliorating intolerance and division may end up exacerbating and reinforcing it.     

Dangerous Enough: Moderating Racial Bias with Contextual Threat Cues

Research shows that participants shoot armed Blacks more frequently and quickly than armed Whites, but make don't-shoot responses more frequently and quickly for unarmed Whites than unarmed Blacks. We argue that this bias reflects the perception of threat — specifically, threat associated with Black males. Other danger cues (not just race) may create a similar predisposition to shoot, and if these cues promote shooting when the target is White, they should attenuate racial bias. We embedded targets in threatening and safe backgrounds. Racial bias was evident in safe contexts but disappeared when context signaled danger, and this reduction was largely due to an increased tendency to shoot White targets.     

Contribution of NIRS to the study of prefrontal cortex for verbal fluency in aging

Healthy aging is characterized by a number of changes on brain structure and function. Several neuroimaging studies have shown an age-related reduction in hemispheric asymmetry on various cognitive tasks, a phenomenon captured by Cabeza (2002) in the Hemispheric Asymmetry Reduction in Older Adults (HAROLD) model. Although this phenomenon is supported by a range of neuroimaging data on memory and inhibitory processes, there is little evidence concerning changes in hemispheric asymmetry for language processing, and particularly word retrieval, which is assessed with verbal fluency task (VFT). This study aimed to investigate the age-related changes in cerebral oxygenation in the prefrontal cortex for both letter and category VFT, varying the complexity of the criteria (i.e., degree of productivity) and using near-infrared spectroscopy (NIRS). Sixteen younger and 16 older adults participated in this study. For both VF conditions, participants were instructed to pronounce as many nouns as possible as a function of high-productivity (e.g., “animals” or “L”) or low-productivity (e.g., “flowers” or “V”) criteria. Behavioral data (i.e., accuracy responses) showed comparable performance in younger and older adults for both VF conditions. However, NIRS data showed more reduced activation (i.e., significantly reduced increase in [O₂Hb] and reduced decrease in [HHb]) in older than younger adults for both VFT. In addition, a bilateral effect was found for both groups, suggesting that VFT requires both executive and language functions. The results are discussed in the context of the current theories of aging.     

Indonesian leadership styles: A mixed‐methods approach

Indonesian leadership characteristics were examined in three studies, using mixed methods. In the first, qualitative study 127 indigenous characteristics of Indonesian leadership were identified from interviews and focus group discussions with Indonesian managers and staff. In the second study, a questionnaire based on the characteristics found in the first study was administered to Indonesian managers to identify Indonesian leadership styles. Using factor analysis, two highly correlated dimensions were extracted, labelled benevolent paternalism and transformational leadership. In the third study, a questionnaire consisting of leadership characteristics from the GLOBE study, supplemented with a selection of 49 items from the Indonesian questionnaire, was administered to another sample of Indonesian managers. We found that Indonesian leadership has two components; the first involves a more local modernization dimension that ranges from (traditional) benevolent paternalism to (modern) transformational leadership, the second is a more universal person‐ versus team‐oriented leadership dimension. We conclude that Indonesian leadership has both emic and etic aspects.     

Enhanced corticospinal response to observed pain in pain synesthetes

Observing noxious injury to another’s hand is known to induce corticospinal inhibition that can be measured in the observer’s corresponding muscle. Here, we investigated whether acquired pain synesthetes, individuals who experience actual pain when observing injury to another, demonstrate less corticospinal inhibition than do controls during pain observation, as a potential mechanism for the experience of vicarious pain. We recorded motor-evoked potentials (MEPs) induced at two time points through transcranial magnetic stimulation while participants observed videos of a hand at rest, a hypodermic needle penetrating the skin, a Q-tip touching the skin, and a hypodermic needle penetrating an apple. We compared MEPs in three groups: 7 amputees who experience pain synesthesia, 11 nonsynesthete amputees who experience phantom limb pain, and 10 healthy controls. Results indicated that the pain synesthete group demonstrated significantly enhanced MEP response to the needle penetrating the hand, relative to the needle not having yet penetrated the hand, as compared with controls. This effect was not observed exclusively in the same muscle where noxious stimulation was applied. We speculate that our findings reflect a generalized response to pain observation arising from hyperactivity of motor mirror neurons not involved in direct one-to-one simulation but, rather, in the representation of another’s experience.     

Attributions of intergroup bias and outgroup homogeneity to ingroup and outgroup others

The research in this article explores the structure and content of attributed intergroup beliefs: to what extent do perceivers think others of their ingroup and their outgroup display intergroup evaluative bias and outgroup homogeneity? We report studies that address this question in ethnicity, gender, and nationality intergroup contexts. In all of these, we show that perceivers attribute to others more biased intergroup beliefs than they themselves espouse. Even when perceivers themselves do not show intergroup bias or outgroup homogeneity, they attribute such biases to others, both others from their ingroup and others from their outgroup. We argue that such attributed intergroup beliefs are fundamentally important to expectations concerning intergroup interaction. Copyright © 2005 John Wiley & Sons, Ltd.     

Metamemory following childhood brain injury: A consequence of executive impairment

In this study, we investigated the influence of children’s level of executive functioning on two types of metamemory knowledge following a traumatic brain injury (TBI). For this purpose, 22 children (aged 7 to 14 years) who had sustained a moderate to severe TBI and 44 typically developing children were recruited. The children with TBI were divided into two groups according to the severity of their executive impairment. Injury severity was determined by the Glasgow Coma Scale (GCS) score on admission or by the duration of unconsciousness. All children were then tested on both their knowledge of general memory functioning and their level of memory self-awareness, respectively assessed using the total number of correct responses on an adapted version of a metamemory interview and a self-other discrepancy score on a questionnaire evaluating everyday memory abilities. Data analyses revealed that participants with TBI who suffered impaired executive functions demonstrated less general metamemory knowledge, and underestimated the frequency of their memory problems, compared with children with TBI who had preserved executive functions and with control participants. Considering the well-established effect of metamemory knowledge on people’s spontaneous implementation of strategies, the interest and the importance of these findings on both theoretical and clinical grounds are discussed.
