A computer simulation modeled the change of attitudes in a population resulting from the interactive , reciprocal, and reeursive operation of Latan~'s (198 I) theory of social impact, which specifies principles underlying how individuals are affected by their social environment. Surprisingly, several macrolevel phenomena emerged from the simple operation of(More)
We integrated research on emotion and on small groups to address a fundamental and enduring question facing alcohol researchers: What are the specific mechanisms that underlie the reinforcing effects of drinking? In one of the largest alcohol-administration studies yet conducted, we employed a novel group-formation paradigm to evaluate the socioemotional(More)
Many theories of exposure effects involve the operation of psychological processes that depend on some form of stimulus recognition. Two experiments investigated the role of stimulus recognition in the mere exposure phenomenon. Female subjects viewed novel stimuli at various exposure frequencies, then measures of stimulul recognition and effect were(More)
Collaboration plays a critical role in scientific creativity. This article draws on research involving small groups and interpersonal relationships to analyze the social processes underlying scientific collaboration. 3 stages of activity in collaborative groups are discussed: formation, performance, and dissolution. In regard to group formation, we consider(More)
There are two schools of thought on how network structures create the competitive advantage known as social capital. One school focuses on the advantages of closure. A network is closed to the extent that people in it are connected by strong relationships. Typical forms of closure are dense networks in which everyone is connected to everyone else, and(More)
A great deal of risky activity occurs in social contexts, yet only recently have studies begun to examine the impact of drinking on risk-seeking behavior in groups. The present study sought to extend this work by examining both pharmacological and expectancy (dosage-set) effects of drinking. In addition, by using a much larger sample than in prior studies(More)
This experiment examines the dynamics of preference change in the context of face-to-face negotiation. Participants playing the role of ''student'' or ''financial aid officer'' exchanged proposals regarding the terms of a student loan. Consistent with dissonance theory, participants increased their liking for proposals they offered and/or ultimately(More)
This article reviews literature that takes a temporal perspective on groups, focusing particularly on the theories that guide such work. The temporal perspective is a process-focused view that treats groups as systems in which change occurs across multiple time scales. The review is organized around six themes that have been especially generative: (a) Time(More)
Although much drinking occurs in social settings, there has been little testing of alcohol in groups. The authors examined the effects of alcohol on performance on a group decision-making task. Fifty-four unacquainted male social drinkers were randomly assigned to 3-person groups that consumed either alcohol (0.82 g/kg) or a placebo. After drinking,(More)
