The comparison of visual processing ability between learning disabilities and normal children
Abstract:
The objective of this research was to study test performance and compare mean
score of visual processing ability which was assessed by VMI 3rd Revision and The
TVPS:NM-R between children with learning disabilities and normal ones. The sample
subjects were divided into 2 groups, that is, the group of LD children whose age
ranged from 6 to 18 years old with a psychiatrist’s diagnosis as LD and/or who had
some characteristics of LD as shown from The Nonverbal Learning Disabilities Scale,
who showed no mental retardation as measured from the Intellectual Test and who got
lower scores on Performance IQ than Verbal IQ. The number of subjects in this LD
group was 30 who were 16 males (53.33%) and 14 females (46.67%). The other 30
children were in the group of normal children whose age, sex and educational level
were matched with the LD group. All obtained data are analyzed by using t-test at the
statistically significant level of .001
The results of this study revealed that the mean score of VMI 3rd Revision and
The TVPS:NM-R between LD and normal children were significantly different at the
level of .001.
These findings revealed that the VMI 3rd Revision and The TVPS: NM-R can
be effective tests to evaluate visual processing ability. The test outcomes can be useful
to separate children with LD from normal ones. In addition, both tests are
standardized, useful for a wide range of ages and cover many dimensions. So, these
might be alternative test instruments for efficient evaluation of LD children at both
early and later stages in order that their disabilities be determined as they are growing
up. This can help decide the appropriate line of intervention or remedy
