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)
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)
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)
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)
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)
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)
OBJECTIVE Social factors affect alcohol use and misuse, yet researchers rarely study the acute effects of alcohol in groups. This study used systematic observation techniques to measure the effects of alcohol on behavioral responses during an initial group interaction. METHOD Fifty-four male social drinkers were assembled into three-person groups of(More)
The confluence model of intellectual development was estimated for a within-family sample of 321 children from 101 transracial adoptive families. Mental ages of the children and their parents, as well as birth or adoption intervals, were used in a nonlinear least-squares estimation procedure to obtain children's predicted mental ages. Contrary to an earlier(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)
