The present research was designed to examine the impact of temporal constraints on group interaction and performance. Thirty-six triads worked on one of two planning tasks under conditions of time scarcity, optimal time, or time abundance. Group interactions were videotaped and coded using the TEMPO system. Each group's written solution was rated on length, originality, creativity, adequacy, issue involvement, quality of presentation, optimism, and action orientation. Each proposal suggested during the interaction was rated on creativity and adequacy. Interaction process data showed that time limits were inversely related to the amount of task focus shown by groups. Performance data showed that the effects of time limits on group performance varied depending on what aspects of quality were considered. Process-performance relationships were also examined within each time condition. The findings are discussed in terms of an attentional focus model of time limits and group performance.
