Abstract


This study intends to test the validity of PMRA based on relationships with other variables and internal structures. This non-experimental quantitative approach in 61 children aged 5-8 discusses the correlation between PMRA with digit span and knox cube. Pearson product moment indicates that PMRA has a positive significant correlation with digit span and knox cube; i.e. PMRA verbal deret maju with digit forward (r=.557, p=<.001), PMRA verbal deret mundur with digit backward (r=.311, p=.015), and PMRA visual-spatial with knox cube (r=.393, p=.002). The analysis signifies that the working memory ability of children 7-8 (n=31) higher than aged 5-6 (n=30) in three parts of PMRA. Based on the two statistical data processing, PMRA is stated to be a valid working memory function measuring tool of children aged 5-8.
