A conditioning model can be used to explain the evaluation process and interpersonal attraction. Since number of trials is an important variable in conditioning research, it was predicted that evaluation of a neutral stimulus should become progressively more positive with trials when paired with positive reinforcers and it should become more negative when paired with negative reinforcers. Subjects in the experimental groups were presented with 15 paired presentations of a geometric figure and attitudes that were either similar or dissimilar. Subjects in the control groups were presented with attitudes without the figure. Evaluations of the figure were made before and after the presentations. Evaluations became more negative over trials when the figure was paired with dissimilar attitudes, but there was no change when it was paired with similar attitudes (Groups × Trials interaction, p< .001). There was no change over trials in the control groups. Differential awareness among the groups was not significant. The results demonstrate the utility of the conditioning model. |
