Abstract：This research investigated performance disparities between depressed and healthy adolescents in predicting cooperative motions. In our experiment, we employed a ‘disappearance-prediction’ paradigm. Subjects were required to predict the position of a chaser in a cooperative chasing motion. An independent chase served as a control, while reversed (backward) trajectories established a baseline. The results indicated that healthy adolescents showed lower prediction errors for the forward cooperative chasing trajectories compared to the reversed (backward) trajectories, while depressed adolescents did not show this distinction. In contrast, the prediction accuracy for individual chasing was comparable between the two groups. This study suggests that the prediction bias of cooperative chasing observed in depressed adolescents is attributable to deficits in processing cooperative information, rather than disparities in fundamental motion information processing.
