Background: The study was carried out in two primary schools in Lagos State, Nigeria using 302 respondents aged 6-20 years. The study compared the cognitive function of pupils from Wesley School for the hearing-impaired with pupils from Onitolo Primary School, a main stream public school to see if similarities or differences existed in their cognitive function and to highlight the factors determining their performance on a standard non-verbal test.
Method:The instrument of data collection was the Raven's Standard Progressive Matrices, a standard, non-verbal intelligence test. Statistical association using Chi-Square was used to test for associations between categorical variables. Kruskal-Wallis was used to test for association in variables that were not normally distributed. Regression Coefficient was used to examine linear relationships between selected independent variables and the scores on the standardized test. As it was impossible to individually match human subjects in this study, the variables of class, sex, age and parents' occupations were adjusted for matching by multiple regression analysis. Multiple regression analysis was used to examine which variables were significant predictors of performance taking possible confounders into consideration.
Results:Respondents from Wesley School were much older than respondents from the public main-stream school, class for class. There was no statistically significant difference in their cognitive functions. The mean score difference between the two schools was 0.54 with respondents from Wesley School scoring higher (P > 0.05). Age, sex and class in primary school were determinants of score (P < 0.05). Males scored higher than females. Respondents of skilled parents had the highest scores.
IntroductionThe aim of the study was to assess and compare the cognitive function of two groups of students; the hearing-impaired and the non-hearing impaired using a standard non-verbal test.
Objectives1. To determine the performance of the hearingimpaired group on a non-verbal standard test. 2. To determine the performance of the nonhearing-impaired group on a non-verbal standard test. 3. To determine the performance predictive factors in the two groups. The World Summit for Children of which Nigeria is a signatory promised to give every child a better future [1]. The Universal Basic Education Program was introduced in Nigeria in 1999 further consolidating the vision of the 1990 World Summit [2]. The Universal Basic Education in Nigeria was introduced to give an equitable access to six years of primary school education and three years of a junior secondary school education [2].In Nigeria, the challenges of the handicapped child are by no means insignificant. One of the difficulties faced with the hearing-impaired in Nigeria is that they fall behind in their academic achievements, leave school less qualified than their hearing peers and sometimes without any academic qualification of any kind. Further, their needs are sometimes not met because of parental superstitiou...
