However, the impact of perceptual training on audiovisual integrative abilities remains unclear. Methods: This study randomly assigned 40 older adults to either a training or control group. The training group underwent a five-day audiovisual perceptual program, while the control group received no training. Participants completed simultaneous judgment (SJ) and audiovisual detection tasks before and after training. Results: Findings indicated improved perceptual sensitivity to audiovisual synchrony in the training group, with AVI significantly higher post-test compared to pre-test (9.95% vs. 13.87%). No significant change was observed in the control group (9.61% vs. 10.77%). Conclusion: These results suggested that cross-modal perceptual training might be an effective candidate cognitive intervention to ease the dysfunction of unimodal sensory.展开更多

Though SSDs have been in existence for over four decades, effective training techniques for their use are rarely discussed. In this paper, we compare three training strategies on a particular SSD known as the vOICe. These comparisons were conducted using a minimal but active search and localization task of luminescent discs. These studies show that an interactive training paradigm, which combines the efforts of two trainees at the same time in a tag-like game, is more effective than passive training at a computer console or active training involving search and localization of luminescent discs. This finding supports philosophical views of perception that take interaction with the environment seriously. In particular, we argue that these findings are in support of certain features of the extended mind view as proposed by Andy Clark （2008）. In particular, the study suggests that when environmental conditions are responsive to one＇s behavioral activity, the activity itself is enhanced, as is predicted by the extended mind view.展开更多
