摘要

To compare the effects of different levels of auditory feedback on performance of a pursuit rotor task, each of five groups (20 subjects per group) was given five sessions of practice (seven trials per session). Feedback during Sessions 2 - 4 for four of the groups consisted of momentary clicks for some minimum interval of continuous contact during a session. Clicks were provided by a counter, located behind the pursuit rotor so that the subject could see how many signals he had received during the session. The fifth group (control) received no feedback at any time. The results show that auditory feedback facilitated tracking performance, the greatest facilitation occurring with intermediate levels of feedback, though not all differences between groups were statistically dependable. Differences between the feedback groups and the control group decreased when feedback was withdrawn (in Session 5). (Author)
