Saving the worst for last: The effect of time horizon on the efficiency of negotiating benefits and burdens

Three experiments explored the effect of outcome delays—longer time horizons for the realization of outcomes—on the efficiency of negotiated agreements. We hypothesized that there would be a positive relationship between a longer temporal distance to the consequences of negotiated agreements and the efficiency of those agreements. Outcome delays did increase the efficiency of the negotiated agreements. In addition, type of resource, burden or benefit, moderated this relationship. Because negotiating for burdens is more difficult than negotiating for benefits in the present, the salutary discounting effects of outcome delays were greater for burdens. The multifaceted effects of time on negotiations are discussed.     

Mothers' Impact on Daughters' Cardiovascular Reactivity in a High‐Threat Context: An Immersive Virtual Environment Study

Applying Attachment Theory, research on confirmation, the Entropy Model of Uncertainty, and the Biopsychosocial Model of Challenge and Threat, this investigation examined the role of mothers' communication on adolescents' cardiovascular response to threat. An experimental design allowed for the manipulation of maternal response to daughters experiencing a rapidly approaching wildfire in an immersive virtual environment. Results revealed complexities in the relative benefits of maternal vocalic presence during high‐threat situation, with the mother's history of confirming feedback playing an important role in daughters' cardiovascular response. Implications for knowledge are addressed and methodological possibilities of using immersive virtual environments are noted.     

Epistemology and the theory of problem solving

Problem solving has recently become a central topic both in the philosophy of science and in cognitive science. This paper integrates approaches to problem solving from these two disciplines and discusses the epistemological consequences of such an integration. The paper first analyzes problem solving as getting a true answer to a question. It then explores some stages of cognitive activity relevant to question answering that have been delineated by historians and philosophers of science and by cognitive psychologists and artificial intelligencers. The traditional opposition between discovery and justification is challenged. It is suggested that epistemology may be conceptualized, in part, as the critical assessment of problem-solving strategies.     

Going to extremes for one's group: the role of prototypicality and group acceptance

To explore who goes to aggressive and antisocial extremes on behalf of their group we primed perceptions of (a) group prototypicality (peripheral vs. central) and (b) ease of acceptance by the group. Participants were members of self‐significant groups—fraternities and sororities (N = 218). Drawing on social identity theory, uncertainty‐identity theory and the social identity theory of influence through leadership, we found, as predicted, that peripheral members who believed it was easy to be accepted were most likely to intend to engage in and support antisocial and aggressive intergroup behaviors. This effect was somewhat stronger among males than females, and strengthened among the most highly identified participants. The research's potential for understanding socially harmful intergroup violence is noted.
