Experimental research by social and cognitive psychologists has established that cooperative groups solve a wide range of problems better than individuals. Cooperative problem solving groups of scientific researchers, auditors, financial analysts, air crash investigators, and forensic art experts are increasingly important in our complex and interdependent society. This comprehensive textbook--the first of its kind in decades--presents important theories and experimental research about group problem solving. The book focuses on tasks that have demonstrably correct solutions within mathematical, logical, scientific, or verbal (...) systems, including algebra problems, analogies, vocabulary, and logical reasoning problems.The book explores basic concepts in group problem solving, social combination models, group memory, group ability and world knowledge tasks, rule induction problems, letters-to-numbers problems, evidence for positive group-to-individual transfer, and social choice theory. The conclusion proposes ten generalizations that are supported by the theory and research on group problem solving. Group Problem Solving is an essential resource for decision-making research in social and cognitive psychology, but also extremely relevant to multidisciplinary and multicultural problem-solving teams in organizational behavior, business administration, management, and behavioral economics.

The selection strategies of individuals and 2-person cooperative groups were investigated in 5 concept-attainment problems. 2 types of stimulus displays were used: (a) form displays, consisting of geometric forms varying in 6 attributes with 2 levels of each, (b) sequence displays, consisting of 6 plus and/or minus signs in a row. The arrangement of cards in the stimulus displays was ordered or random. The principal results were: (a) 2-person groups used the focusing strategy more, required fewer card choices to solution, (...) and required more time than individuals; (b) form displays resulted in more use of the focusing strategy than sequence displays, with no difference in number of card choices; (c) no difference between ordered and random arrays in use of the focusing strategy or number of card choices.
