Comparison of visual and proprioceptive training on multisensory perception using a new designed setup

Many studies evaluate the multisensory integration to investigate how the human brain combines senses information and weighted each of senses in different situations. The effect of sensory training on multisensory integration is subject to a few of research. The purpose of the present study is to evaluate and compare the effect of both modalities, i.e., visual and proprioception training in multisensory integration. To achieve to this aim, a set of experiment was designed in which the subject was asked to move his/her hand in a circle and estimate its position through a new designed setup. The experiment was performed on 8 subjects with trained proprioception and 8 subjects with visual training. Results of the experiments have three important points: 1) learning rate of visual is significantly more than that of proprioception; 2) the mean of visual and proprioceptive errors are decreased by training but statistical analysis shows this decreasing is significant for proprioceptive error and non-significant for visual error, and 3) visual errors in training phase even in the beginning of it, is much less than the main test stage because in the main test the subject have to focus on two sense.
