The objective of this research was to study test performance and compare mean score of visual processing ability which was assessed by VMI 3('rd) 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 gotlower 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 3('rd) 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 3('rd) 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. |
