摘要:This study discusses the Cognitive Assessment System (CAS) in assessing cognitive processing. CAS is capable of measuring not only the cognitive ability and process but also of able to determine the deficits in relation with specific reading skills. Therefore, this study aims to examine the relationship of PASS cognitive processes with the reading components of Wide Range Achievement Test-4 (WRAT-4). The CAS and WRAT-4 were administered to a hundred primary standard three Malaysian children but based on American norms. The full scale of CAS mean scores was 98 which is the average level of cognitive processing among the subjects. While the WRAT-4 reading components showed the mean score of overall reading performance was 90 which slightly reach the average level. Correlation analysis revealed that cognitive processes were significantly correlated with overall reading performance with r=0789, p<0.01. Simultaneous and Planning processing had quite strong relationship with the overall reading performance which was r=0.724, p<0.01 and r=0.676, p<0.01 respectively. However, Successive processing had low score of r = 0.393, p < 0.01 for the correlation with reading comprehension. CAS is one of the alternatives in providing such capabilities in measuring cognitive processes that could predict reading deficits and relevant to identify performance on reading-related skills.
