PSM studies III. A model of post-stimulatory masking phenomena

The experimental results obtained from a study of post-stimulatory masking phenomena are summarized. Two mechanisms are postulated to explain these results. A model, based on these two mechanisms, is derived, and comprises the input from the auditory senses, on which preliminary decisions and actions are taken, followed by a selective filter and limited capacity channel leading to the higher brain centres which can effect overriding control on the system. This model is used to provide explanations of the experimental results obtained in this study.
