Abstract
-
Contemporary theories have attributed reading disability to deficiencies or strengths in certain cognitive functions, including temporal sequencing and visuo-spatial ability. Impairments or strengths in these functions have also been associated with left-handedness. The findings, however, have been conflicting. The present study examined the relationships among reading ability, hand preference, sequencing, and spatial skills.;The subjects were 46 average and poor readers (boys aged 7.5-11.5) who were right- or left-handed. Poor readers obtained Gray Oral Reading Test-R scores which were at least 1.5 standard deviations below their scores on a nonverbal intelligence test; average readers performed similarly on the reading and intelligence tests. Left-handers performed at least 6 of 10 activities on the Harris Test with the left hand, including writing; right-handers performed 9 of 10 activities with the right hand.;Five sequencing tasks were administered: auditory verbal (digits)--repetition of digit sequences; auditory verbal (words)--repetition of word sequences; visual verbal--pointing to sequences of pictures (familiar objects); visual nonverbal--pointing to sequences of pictures (nonsense shapes); and motor--replication of finger sequences. Two spatial tests were administered: the Right-Left Orientation Test and the Spatial Orientation Memory Test.;Average readers performed better than poor readers on the auditory verbal (digits), visual verbal, visual nonverbal, and motor sequencing tasks, and showed a tendency towards better performance on the auditory verbal (words) task. Right-handers performed better than left-handers on the auditory verbal (words) task, and showed a tendency towards better performance on the auditory verbal (digits) and motor tasks. Although reading groups did not differ on spatial tasks, left-handers performed better than right-handers on the Right-Left Orientation Test. There were no interactions between reading and handedness groups.;These results confirm reports of a general sequencing impairment among poor readers for visual and nonverbal as well as auditory and verbal stimuli. The sequencing deficit was manifested by left- as well as right-handed poor readers. The hypothesis that left-handers would have poor sequencing and good spatial skills, due to weak left and strong right hemisphere functioning, was partially supported.
