ABSTRACT: Background: Previous studies have demonstrated the plasticity of perceptual sensitivity and compensatory mechanisms of audiovisual integration (AVI) in older adults. 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.
