Talking Nets: A Multi-Agent Connectionist Approach to Communication and Trust between Individuals

A multi-agent connectionist model is proposed that consists of a collection of individual recurrent networks that communicate with each other, and as such is a network of networks. The individual recurrent networks simulate the process of information uptake, integration and memorization within individual agents, while the communication of beliefs and opinions between agents is propagated along connections between the individual networks. A crucial aspect in belief updating based on information from other agents is the trust in the information provided. In the model, trust is determined by the consistency with the receiving agents’ existing beliefs, and results in changes of the connections between individual networks, called trust weights. Thus activation spreading and weight change between individual networks is analogous to standard connectionist processes, although trust weights take a specific function. Specifically, they lead to a selective propagation and thus filtering out of less reliable information, and they implement Grice’s (1975) maxims of quality and quantity in communication. The unique contribution of communicative mechanisms beyond intra-personal processing of individual networks was explored in simulations of key phenomena involving persuasive communication and polarization, lexical acquisition, spreading of stereotypes and rumors, and a lack of sharing unique information in group decisions

History and National Identity Construction: The Great Famine in Irish and Ukrainian History Textbooks

This paper compares the narratives on the Famine in Irish and Ukrainian history textbooks and examines to what extent these narratives are coloured by a nationalist discourse. It argues that the story of the Famine in Irish history textbooks has changed from nationalist propaganda to a more balanced narrative, and that this change was brought about by the social transformations in the 1960s. The paper further observes that the current Ukrainian textbooks display quite a variation in the selection and interpretation of events relating to the Famine. Whereas some show a considerable nationalist bias, others present more moderate views. The trajectory of Irish narratives lends support to a theory that relates politicized historiography to the age of a state and to the consolidation of democracy. The diverse pattern of Ukrainian narratives, however, is difficult to reconcile with theories linking historiography to the wider social and political context. This pattern suggests that young states and/or states emerging from authoritarian rule need not automatically entertain uniformly nationalist or otherwise ideologically coloured discourses in the immediate post-independence period

Organizational Images And Member Identification

We develop a model to explain how images of one's work organization shape the strength of his or her identification with the organization. We focus on two key organizational images: one based on what a member believes is distinctive, central, and enduring about his or her organization and one based on a member's beliefs about what outsiders think about the organization. According to the model, members assess the attractiveness of these images by how well the image preserves the continuity of their self-concept, provides distinctiveness, and enhances self-esteem. The model leads to a number of propositions about how organizational identification affects members' patterns of social interaction.Managemen

Gangs, displaced, and group-based aggression

Many urban areas experienced an alarming growth of gang activity and violence during the end of the 20th and the beginning of the 21st centuries. Gang members, motivated by various factors, commit a variety of different types of violent acts towards rivals and other targets. Our focus involves instances of displaced aggression, which generally refers to situations in which aggression is targeted towards individuals who have either not themselves committed an offense against the aggressor (s), or who provide an offense that is too mild to justify the aggression levels that are expressed towards them. We discuss how social–psychological mechanisms and models of two types of displaced aggression might help explain some aspects of the retaliatory behavior that is expressed by members of street gangs. We also propose general techniques that have the potential to reduce such aggressive behavior

Combined Effects of Knowledge About Others' Opinions and Anticipation of Group Discussion on Confirmatory Information Search

There is conclusive evidence that information search processes are typically biased in favor of the information seeker’s own opinion (confirmation bias). Less is known about how knowledge about others’ opinions affects this confirmatory information search. In the present study, the authors manipulated feedback about others’ opinions and anticipation of group interaction. As predicted, the effect of knowledge about others’ opinions on confirmatory information search depended on whether participants anticipated interacting with these others. Specifically, minority members anticipating a group discussion exhibited a particularly strong confirmation bias, whereas minority members who did not anticipate a discussion predominantly sought information opposing their opinion. For participants not anticipating group interaction, confidence about the correctness of one’s decision mediated the impact of knowledge about others’ opinions on confirmatory information search. Results are discussed with regard to the debiasing effect of preference heterogeneity on confirmatory information search in groups

Negotiating Relationally: The Dynamics of the Relational Self In Negotiations

Although negotiation research is thriving, it has been criticized as having an arelational bias—emphasizing autonomy, competition, and rationality over interdependence, cooperation, and relationality. In this article, we advance a new model of relationality in negotiation. Drawing on research in social psychology, we describe the construct of relational self-construals (RSC) and present a temporal model of RSC and negotiation. After delineating the conditions through which RSC becomes accessible in negotiation and conditions that inhibit its use, we discuss how RSC affects negotiators\u27 pre-negotiation psychological states, early and later tactics, and negotiation outcomes. We illustrate a number of distinct relational dynamics that can occur based on the dyadic composition of RSC, each of which brings distinct benefits and costs to the negotiation table. Implications for the science and practice of negotiation are discussed

Professional Practice Guidelines for Occupationally Mandated Psychological Evaluations

Psychological evaluations are relied on by employers, professional licensing boards, and civil service commissions to make hiring and employment decisions affecting individuals, orga- nizations, and the public. To promote best practices, these professional practice guidelines were developed for use by psychologists who perform clinical evaluations of individuals for occupational purposes, regardless of whether the evaluation is intended to obtain employ- ment, to achieve licensure/certification, or to maintain either. These guidelines were created by the Committee on Professional Practice and Standards (COPPS) to educate and inform the practice of psychologists who conduct occupationally mandated psychological evaluations (OMPEs), as well as to stimulate debate and research in this important area

Asian/Pacific Islander Communities: An Agenda for Positive Action

In June of 2001 the National Council on Crime and Delinquency, in cooperation with the John D. and Catherine T. MacArthur Foundation, convened a symposium to assess the current state of research, exchange information, and establish a tentative agenda for action regarding the quality of life and unmet needs of the API population in the United States. Scholars, activists, community-based and non-profit organizations, educators, law and policy experts, and foundations were all present for this conversation. This report includes many of the data and concepts presented and discusses recurring issues, such as the myth of the model minority, documenting the diversity of API communities, and historical issues which affect federal policies and legislation
