| Popis: | An experiment is described which was designed to test the hypothesis that brief visual stimuli would not be perceived when they occurred during certain phases of the EEG alpha rhythm. The results agreed with the hypothesis. It was concluded that the alpha rhythm is a correlate of the activity of a ‘neuronic shutter' which periodically prevents the reception or processing of visual information by the brain. The procedure used was such that there was no necessity for the subjects to pay attention to the stimuli; indeed, efforts were made to avoid such attention. This methodology was thought to be of importance in obtaining a positive result. |
