Multilevel theory of team decision making: decision performance in teams incorporating distributed expertise

Article Abstract:

The purpose of this research was to develop and test a theory of decision-making performance for hierarchical teams with distributed expertise. This theory identifies 3 core team-level constructs (team informity, staff validity, and hierarchical sensitivity) and 3 constructs below the team level that are central to decision-making accuracy in hierarchical teams with distributed expertise. Two studies are presented to test the proposed theory. A total of 492 college students worked on a computerized command-and-control simulator. Results from these studies are discussed in light of the theory. Similarities and differences in results across the 2 studies are discussed, as are potential modifications of the theory considering the data. Finally, implications of the theory for applied team contexts are elaborated. (Reprinted by permission of the publisher.)

Effect of interpersonal orientation and the sex-type of the task on choosing to work alone or in groups

Article Abstract:

The preferences of men and women for working alone or with others were examined. 150 undergraduates were presented with masculine and feminine tasks and were offered the choice of working alone or with others on the tasks. A cognitive model predicted that the congruence between gender and sex-type of the task would affect expectancies of success, which, in turn would affect choice. From an individual difference perspective, it was predicted that interpersonal orientation would affect choice. The cognitive perspective model was supported, whereas interpersonal orientation had little affect on choice. The results were discussed in terms of their implications for task perceptions and gender differences. (Reprinted by permission of the publisher.)

Team performance on monitoring tasks: an examination of decision errors in contexts requiring sustained attention

Article Abstract:

The purpose of this study was to examine individual and team performance in situations requiring sustained attention. Eighty research participants arrayed in 20 four-person teams worked for 2 separate 3-hr sessions on a naval-command-and-control simulation. The results of the study replicated the past literature on the vigilance decrement and extended the literature by documenting a postcritical signal decrement as well. The study also showed that problems in the area of sustained attention generalize from situations involving individual decision makers to contexts where decisions are made by teams.
