视听知觉训练对老年人认知能力的促进及其机制OA北大核心CHSSCDCSTPCD

Older adults experience a significant decline in vision and hearing with aging,but the visual and auditory perceptual training has shown potential for improving cognitive functions to some extent.Studies have revealed that audiovisual cross-modal interactions have a compensatory and facilitative effect to alleviate the decreased perceptual ability of single-modality in older adults.Audiovisual perceptual training in older adults primarily focuses on audiovisual sensitivity,namely the audiovisual temporal binding window.The results indicate that perceptual training significantly narrows the temporal binding window,enhancing the brain's neural processing efficiency for audiovisual stimuli,and demonstrating the advantages of cross-modal training.Future research should design precise and efficient audiovisual perceptual training programs,leading to targeted enhancement in the audiovisual integration ability and elucidating neural mechanisms underlying compensatory effects in older adults.This will provide a scientific basis and new perspectives for the development of perceptual intervention products,which holds significant practical implications for improving cognitive functions and physical and mental health in older adults.
