Developmental study of human visual and auditory evoked responses.
The present study investigated the development of visual evoked response by varying the physical factor of photic stimulus size and the psychological factor of age and the development of auditory evoked response was investigated on habituation trials, using the subjects of wide range in ages. The results showed that visual evoked response decreased in amplitude as a function of age and increased as a function of stimulus size and the auditory evoked response also decreased in amplitude as a function of age, while no prominent habituation of evoked response over the trial blocks was observed.
