Simple Auditory Reaction Time in Blind and Sighted Adolescents

This study compared simple auditory reaction times of 20 subjects aged between 11 and 15 yr. (M = 13), 10 born-blind from the Louis Braille Institut (Montréal) and 10 normal sighted subjects of the same age and sex. Their task was to press a telegraph key as fast as possible after presentation of an auditory stimulus. Each subject executed five blocks of 10 trials; the blocks were separated by a rest period of 1 min. The results showed no significant difference (p > .05) between born-blind and sighted people of the same sex and chronological age in regard to simple auditory reaction time.
