Abstract
BACKGROUND: Specific learning disabilities (SpLD) viz. dyslexia, dysgraphia and dyscalculia are an important cause of academic underachievement. AIMS: To assess whether cognition abilities vary in children with SpLD having different grades of nonverbal intelligence. SETTING: Government recognized clinic in a medical college. DESIGN: Cross-sectional study. SUBJECTS AND METHODS: Ninety-five children with SpLD (aged 9-14 years) were assessed. An academic achievement of two years below the actual grade placement on educational assessment with a Curriculum-Based test was considered diagnostic of SpLD. On basis of their nonverbal Intelligence Quotient (IQ) scores obtained on the Wechsler Intelligence Scale for Children test, the study children were divided into three groups: (i) average-nonverbal intelligence group (IQ 90-109), (ii) bright normal-nonverbal intelligence group (IQ 110-119), and (iii) superior-nonverbal intelligence group (IQ 120-129). A battery of 13 Cognition Function tests (CFTs) devised by Jnana Prabodhini's Institute of Psychology, Pune based on Guilford's Structure of Intellect Model was administered individually on each child in the four areas of information viz. figural, symbolic, semantic and behavioral. STATISTICAL ANALYSIS USED: The mean CFTs scores obtained in the four areas of information were calculated for each of the three groups and compared using one-way analysis of variance test. A P value < 0.05 was to be considered statistically significant. RESULTS: There were no statistically significant differences between their mean CFTs scores in any of the four areas of information. CONCLUSIONS: Cognition abilities are similar in children with SpLD having average, bright-normal and superior nonverbal intelligence.
