Event-related Slow Potentials in Aphasic, Dyslexic and Normal Children During Pictorial and Letter-matching

Event-related slow (DC) potentials in the human brain

“…Higher activity for older subjects was found if a cumulative voltage measure was taken between 200-Linear correlation coefficients were calculated for ten normal children (5.7-12.7 years; X = 9.5 years) between age and cumulative voltage measures referred to prestimulus baseline for positive shifts occurring during the encodement interval in a three-stimulus paradigm "protracted p 300 waves" (Otto et al 1976). Substantial negative correlations were found for all measurement epochs during the $2-$3 (encodement interval) and for the 320-ms epoch preceding $2.…”

“…In an examination of aphasic, dyslexic and normal children, using a three-stimulus paradigm, Otto et al (1976) found greater positivity in aphasic and dyslexic children in the interval between warning and encodement.…”
