Purpose: Visual illusion affects visual perception and motor planning processes. The aim of the present study was to investigate the effect of Ebbinghaus visual illusion on the accuracy of performance and learning of Volleyball volleying skills.
Methods: seventy two volunteer female students (age 13.4±0.97 year) randomly assigned to three visual illusion groups; perceived larger target (PLT), perceived smaller target (PST) and control. To create Ebbinghaus visual illusion, the target square was surrounded by squares smaller than the target (large illusion) or squares larger than the target (smaller illusion). The participants completed the self-efficacy questionnaire after the pre-test and observing the visual illusion. The acquisition phase consisted of 10 blocks of 30 seconds of performing volleyball volleying skill with the visual illusion specific to each group. After 24 hours, the retention test and after 10 minutes, the transfer test were performed.
Results: The finding of the research showed that the effect of visual illusion on acquisition, retention, transfer and self-efficacy in Volleyball volleying skills was significant and post hoc test showed that the PLT group was beter than the other groups.
Conclusion: Result showed that perceptual manipulation of performance expectancies through visual illusion can provide optimal conditions for the performance and learning of Volleyball volleying skills in beginners by increasing self-efficacy.
