The perirhinal cortex and long-term familiarity memory.

To analyse the functions of the perirhinal cortex, the activity of single neurons in the perirhinal cortex was recorded while macaques performed a delayed matching-to-sample task with up to three intervening stimuli. Some neurons had activity related to working memory, in that they responded more to the sample than to the match image within a trial, as shown previously. However, when a novel set of stimuli was introduced, the neuronal responses were on average only 47% of the magnitude of the responses to the set of very familiar stimuli. Moreover, it was shown in three monkeys that the responses of the perirhinal cortex neurons gradually increased over hundreds of presentations (mean = 400 over 7-13 days) of the new set of (initially novel) stimuli to become as large as those to the already familiar stimuli. Thus perirhinal cortex neurons represent the very long-term familiarity of visual stimuli. Part of the impairment in temporal lobe amnesia may be related to the difficulty of building representations of the degree of familiarity of stimuli. A neural network model of how the perirhinal cortex could implement long-term familiarity memory is proposed using Hebbian associative learning.     

Intergroup contact,friendship quality and political attitudes in integrated and segregated schools in Northern Ireland

Background This study examines the effects of integrated and segregated schooling on Northern Irish children's self‐reported contact and friendship with members of the other denominational group in school and community settings. Aim To assess the effects of cross group friendships and cross group contacts in school and outside school on children's political attitudes. Sample A cross‐sectional design was employed with 1732 children being assessed at three age levels 11,12 & 14 years in eight‐matched integrated, maintained (Catholic) and controlled (Protestant) schools. Method Lisrel modelling was used to investigate the interrelationships among cross group friendship quality, cross group contacts in school and outside school and children's political attitudes. Results Intergroup contact within and outside school was reported frequently in integrated schools but only occasionally in segregated schools. Modelling revealed that cross group contacts in school and outside school were both associated with less extreme political attitudes. Friendship quality with cross group members had no significant effects on political attitudes. Conclusions The results provide support for educating Protestants and Catholics together as a means of moderating attitudes and creating cross‐community friendships in a divided society.

A 10-day developmental voyage: converging evidence from three studies showing that self-esteem may be elevated and maintained without negative outcomes

Empirical evidence shows that educational experiences in the context of the outdoors lead to elevated self-esteem. Although elevated self-esteem is widely assumed to promote beneficial outcomes, recent evidence suggests that elevated self-esteem may also facilitate a variety of negative outcomes (i.e., increased prejudice, aggression, drug and alcohol abuse). The current research was conducted in order to examine whether one type of outdoor educational experience—a 10-day developmental voyage—could elevate adolescents’ self-esteem without also elevating negative outcomes. The data from three separate studies are reported. Study one revealed that adolescents who undertook the voyage manifested elevated self-esteem and decreased gender prejudice (i.e., less negative ratings of opposite sex outgroup members). Study two replicated these findings and further demonstrated that these effects were maintained 4–5 months following the voyage. In study three, in addition to self-esteem, risky attitudes (i.e., towards drug and alcohol use), physical aggression, verbal aggression, racial and gender bias were also examined. Adolescents again showed elevated self-esteem that was maintained 4–5 months following the voyage. There were no changes in risky attitudes, aggression, or racial and gender bias. Taken together these results indicate that taking part in a 10-day developmental voyage—can lead to an elevation in self-esteem, that is maintained over time and which does not facilitate a variety of negative outcomes.     

Group membership, strength of group identification and perceptions of violence for locations in Northern Ireland

118 undergraduate students, all of Northern Irish origin, were asked to rate 60 locations in Northern Ireland for violence and denominational composition. As expected from Social Identity Theory, subjects perceived ingroup locations as less violent than outgroup ones. Contrary to expectations, however, there was no increased differentiation of violence judgements with increasing strength of identity, for which two possible explanations were considered.     

Listening to the Language,Listening to the Words and Listening to the Spaces between the Words: Rhetoric and Pragmatics in the Performance of Christian–Muslim Relations

The article argues for the need to look beyond the texts used within the context of interreligious dialogue, and to focus just as much on the context and the way in which the texts are expected to be heard. It focuses specifically on Christian–Muslim dialogue at an event in Iran where the author was present. By looking at the use of rhetoric and pragmatics within his own contribution to this event, he raises questions about the way in which those contributing to dialogue communicate with the many different audiences involved, and the way in which their messages are received by those audiences. By focussing on this one event, the aim is to show what might be achieved through this kind of analysis and to call for more work to be done in this kind of way.

New measures of political attitudes in Northern Ireland: a social identity perspective

Twenty‐eight measures of political attitudes were validated on a sample of 388 undergraduate students from Northern Ireland. Confirmatory factor analysis showed the scales to be unidimensional, discriminantly valid, with generally excellent reliabilities. The pattern of intergroup differentiation between Catholics and Protestants conformed to Social Identity Theory, with maximum differentiation on important issues, Catholics adopting a social change ideology and Protestants defending the status quo. Catholics and Protestants resolved their respective group associations with violence by condemning both it and terrorism, and also reported interdenominational friendships. The utility of these new measures of political attitudes in terms of measuring changes due to political initiatives, cross‐community reconciliation programmes and in assessing changes in attitudes as a result of integrated or segregated denominational schooling within the Province is outlined.
