Investigation of Model Human Processor by EEG Measurement

We repeat the interaction cycle of recognition, judgment and action while practicing skills. The interaction cycle was modeled by Card et al. from the viewpoint of information processing, which is called as Model Human Processor. Model Human Processor can estimate the reaction time of the cycle. However, Model Human Processor does not estimate processing time from the aspect of brain science, but estimates it by empirical model. In this study, we performed four experiments according to Model Human Processor and measured brain activity by Electroencephalography (EEG). As a result of experiments, characteristic EEG was detected. Also, it was found that characteristic EEG was appearing late as well as models delayed cognitive processors of reaction decisions.
