THE INTERACTION OF RESPONSES IN THE BRAIN TO SEMANTIC STIMULI

摘要: Long time-constant EEG recording during paired stimuli has led to the discovery of contingent negative variation or expectancy wave (Walter, 1964). This effect is produced when a conditional stimulus signals that an imperative demanding action, decision, attention will follow at short, constant time interval. Symbolic and meaningful were presented subjects tachistoscopically, evoked responses in brain electronically averaged. The cerebral such psychological are more complex than flashes. A slow DC potential shift (CNV) was seen interval between auditory ready signal visual exposure if recognition required, it interesting. Following exposure, positive occurred. method been developed study stimuli. amplitude relates information content subjective factors rather physical strength stimulus.
