Experimental Formation of Visual-Auditory Associations on Phoneme Recognition

The formation of visual-auditory associations on recognition of speech sounds (phonemes) in conditions of simultaneous presentation of visual stimuli was studied. Two categories of visual stimuli were used – images of gestures and geometrical figures. The formation of visual-auditory associations was assessed in terms of degradation of response parameters in control experiments after completion of training. The protocol for presentation of combined pairs of stimuli included new combinations of stimulus pairs differing from those used during training to visual-auditory interactions. Reaction times and the proportions of correct responses were measured on phoneme recognition. These experiments showed that use of images of gestures as visual stimuli produced marked visual-auditory associations, which contrasted with combinations of sounds with images of geometrical figures. It is suggested that these differences can be explained in terms of the involvement of the neuron system operating in gesture perception in forming visual-auditory associations.
