The present study extended the Lewis and Goldberg (1968) study and included the parameter of infant temperament as defined by Thomas, Chess, Birch, Hertzig and Korn (1963). As in the Goldberg study, the index of response decrement was used as a measure of the infant’s development. It was hypothesized that response decrement would be positively correlated with high frequency of caregiver stimulation and negatively correlated with high infant intensity and activity ratings. Response decrement is the measured decrease in the amount of time an infant looks at a novel stimulus after several trials. It was computed by observing the infant’s fixation to a single blinking light over four trials, and subtracting the total amount of time looking on trial from trial one.
