The present study was conducted to understand the nature of relationship between working memory and fluid-crystallized intelligence. A sample of 250 (135 male and 115 female) students of 11th and 12th grade was tested on Operation Span and Reading Span tasks of working, Culture Fair Intelligence Test, and Hundal General Mental Ability Test. Results of correlational analysis indicated that all the measures of fluid and crystallized intelligence correlated significantly with Operation Span and Reading Span measures of working memory. The overall score of Culture Fair Intelligence Test correlated .43 and .35 with Operation Span and Reading Span, respectively. Scores on all the seven subtests of HGMAT have also shown significant positive correlation with the measures of working memory. Total HGMAT score correlated .40 and .44 with Operation Span and Reading Span, respectively. Structural analysis provided three distinct factors which were interpreted as crystallized intelligence, fluid intelligence, and working memory.
