Analysis of the Averaged Visually Evoked Potentials in Normal Children. (RIEEC Research Bulletin 3.)

Evaluated were the properties and fine structures of averaged visually evoked potentials (AVEP) in 60 normal children between the ages of 2 and 9 years. Electroencephalographic recordings were taken while white diffuse flashes were used to deliver visual stimuli to the Ss. Three types of AVEP patterns were discerned, with no relationship observed between AVEP types and age of Ss; however, AVEP latencies of the third type appeared to be closely related to age. Results implied that AVEP latency is related to age in early developmental stages but becomes unrelated to age at later stages. (LH)
