Discriminant Reaction Time as a Measure of Attention in the Reading Disabled Child.
Culbert, James P.
A study was conducted to determine if attentional difficulties would be found in reading disabled children and to discover if increasing the complexity of a task would result in a relative decrease in the performance of the children. Twelve dyslexic boys, aged eight and nine, and 12 normal subjects similar in age and IQ participated in the study. The subjects were tested for reaction time and then completed a computer controlled test (Discriminant Reaction Time--DRAT), which combines reaction time and number discrimination and requires the subject to observe rapidly presented digits and to respond by pressing a button each time a designated number appears. If the subject responds before the next digit appears, the rate of presentation is speeded. If he or she misses the number or responds late, the rate is slowed. Performance is defined in terms of the average rate of stimulus presentation for the missed stimuli with a correction made for false hits. Results showed that the dyslexic children were significantly slower on reaction time when compared to the control group children and performed significantly worse than the controls on the DRAT. The poor performance on the DRAT supports the theory that reading disabled children are less able to focus on relevant task items for a sustained period. (FL)
