We consider group decision-making on an optimal stopping problem, for which large and stable individual differences have previously been established. In the problem, people are presented with a sequence of five random numbers between 0 and 100, one at a time, and are required to choose the maximum of the sequence, without being allowed to return…

Differences were investigated between communication behaviors of small groups trained or not trained in creative problem-solving. The 110 members of groups trained in problem solving participated more, criticized ideas less, supported ideas more, exhibited more verbal and nonverbal indications of humor, and produced more ideas than the 90…

The purpose of the Commons Game is to teach students how social traps work; that is, that short-term individual gain tends to dominate long-term collective gain. Simulations of Commons Dilemma have grown considerably in the last decade; however, the research has used small face-to-face groups to study behavior in the Commons. To compare the…

A study analyzed and compared four selected models in the cyclical tradition of group development as a basis for identifying possible issues and implications for future theory building. The theorists whose models were examined were Leland Bradford, Jack Gibb, William Schutz, and Theodore Mills. Both historical and conceptual perspectives of the…

The techniques, procedures, and principal findings of 15 different experiments in a research program on interactive communication are summarized in this paper. Among the principal findings reported are that: problems are solved faster in communication modes that have a voice channel than in those that do not have a voice channel, modes of…
