Abstract
-
The present study investigated lateral differences in simple manual reaction time (RT) to verbal and non-verbal sounds when these stimuli were monaurally presented to 5 to 10 year old children. Seventy-one male and female children, 20 in kindergarten, 25 in second grade, and 26 in fourth grade were studied. All subjects were of average school achievement and were right-handed as ascertained by a handedness inventory. The taped stimuli were the words 'run' and 'jump', the sound 'nur' ('run' in reverse), and a sinusoidal 200 Hz. tone. The order of the stimuli and the ear of presentation were interdispersed to avoid attentional set. The children responded to the stimuli by lifting the index fingers of both hands from telegraph keys as soon as they heard the stimuli.;The results of a four-way analysis of variance indicated a statistically significant faster response to stimuli presented to the right than to the left ear. This right ear advantage (REA) occurred for all four stimuli at all grade levels. No age differences or gender differences were found for the ear advantage. In addition, only for the boys, there was a faster RT with the left hand to all stimulus sounds. The results of the study were discussed in terms of Kinsbourne's attentional model.
