Description

Learning is typically enhanced when information is provided both auditory and visually. Interestingly, audiovisual learning (AVL) can also improve subsequent visual-only performance, i.e., when the auditory information is not present anymore. The multisensory predictive coding framework (MPCF) suggests that this benefit of AVL is due to the improved prediction of the visual input by recruiting both auditory and visual brain areas. The primary aim of the present study is to test this assumption by means of functional magnetic resonance imaging (fMRI). For this, two groups of students are trained to detect the direction of a movement (i.e., leftwards or rightwards) in random dot patterns. While the visual group is trained with visual information only, the audiovisual group receives an additional auditory movement cue. Before and after the training both groups perform an identical visual-only pre/posttest in the scanner. In the posttest, we expect to see a direction-specific pattern of activation in auditory motion sensitive areas for the audiovisual group but not for the visual group.
