The Delphi technique: an empirical evaluation of the optimal number of rounds
Article Abstract:
The question of how many rounds of questionnaires and feedbacks should be included in a Delphi procedure is addressed. In order to identify the point of stability for Delphi groups, 72 university students were arranged in 4 person Delphi groups and were given the NASA Moon Survival Problem to work on through six iterations. Mean quality scores, mean differences scores, and the Duncan multiple-range test were calculated. The results demonstrate that the Delphi technique achieves its maximum effectiveness if it is allowed to progress through four iterations and that by this point the Delphi group achieves stability.

Group interaction behaviors that affect group performance on an intellective task
Article Abstract:
How a group works can be defined by the interaction that occurs while a group completes a cooperative task. A group style instrument was developed and used to examine two independent samples of subjects participating in groups. Interaction was studied in terms of changes in responses to items over time. The group instrument took levels of group performance into account. A discussion is included that focuses on descriptions of interaction behaviors that discriminated between performance levels. Group feedback applications are described and implications for future research are given.

The social information processing model of task design: conflicting cues and individual differences
Article Abstract:
Thirty women in a mid-sized southern city participated in a study designed to test the social information processing task design model in a realistic work setting. Subjects were hired on a part-time, temporary basis to perform clerical work. Some received positive supervisor cues, some received cues which were positive from the supervisor but negative from a co-worker, and some received no social cues at all. Results indicate that social cues may not have much effect on perceived task characteristics, but are important in influencing other task-role perceptions.
