Reaction Time as a Predictor of PPVT Performance in Preschoolers.
Telzrow, Cathy F.; Hartlage, Lawrence C.
The relationships between reaction time (RT), movement time (MT), visual hemi-space preferences in RT and MT, and the Peabody Picture Vocabulary Test (PPVT) were investigated in order to evaluate reaction time as a measurement practice with very young children. The sample was composed of 49 white, middle-class children ranging in age from 24 to 77 months and clustered into three age categories. A variation of the reaction time device described by Jensen (1980, 1981) was used to record RT and MT scores. All testing was conducted individually by a certified school psychologist in the child's home or in a regularly attended day care center. Results suggest that, since performance time was shown to decrease with age, both RT and MT are developmental phenomena. Significant correlations between RT, MT, and PPVT scores suggest that RT and MT may be related to general cognitive ability. Since median RT is correlated significantly with right hemi-space RT but not with left, visual hemi-space differences also provide support for the concept of psychological intelligence. (RH)
