"Collective induction: Social combination and sequential transition": Correction to Laughlin and Futoran

Reports an error in "Collective induction: Social combination and sequential transition" by Patrick R. Laughlin and Gail C. Futoran ( Journal of Personality and Social Psychology, 1985[Mar], Vol 48[3], 608-613). One sentence reads incorrectly on page 610. The correct sentence is provided in the erratum. (The following abstract of the original article appeared in record 1985-20078-001.) 240 undergraduates, as individuals and 4-person cooperative groups, attempted to induce a rule that partitioned a deck of standard playing cards into exemplars and nonexemplars. A trial consisted of (a) individual member hypotheses, (b) group hypothesis (omitted in individual conditions), (c) choice of any of the cards, and (d) feedback on the exemplar or nonexemplar status of the card. Ss were instructed to select cards to confirm or disconfirm the current hypothesis, or received no such instructions. Groups had significantly more correct final hypotheses, plausible final hypotheses, and overall plausible hypotheses than individuals. Performance was better for both individuals and groups under control instructions than either instructions to select cards to confirm or disconfirm hypotheses. Social combination analyses and sequential transition analyses indicated that the groups were remarkably able to recognize and adopt the correct hypothesis if and only if it was proposed by at least 1 group member on some trial. Thus, the superiority of collective induction over individual induction was due to superior hypothesis evaluation by groups rather than to superior hypothesis formation by groups.
