| Abstract: | 144 Subjects divided into four-person groups participated in three discussions. In each group, one member (Target subject) was preselected as either being high or low in cognitive complexity. The groups were then assigned to one of three conditions. Under Continuous Reinforcement the Target subject received a reinforcing light cue following each verbalization in the second of three discussions (no light cues used in the first and third discussions). Target subjects under Partial Reinforcement received light cues on a 50% variable ratio reinforcement schedule. Control subjects received no light cues in any session. Target subjects in both experimental groups showed conditioning effects on all dependent measures. While no differences were found between reinforcement conditions, results suggest that abstract subjects are able to make more use of feedback cues than concrete subjects. |
