Objective: Current views of working memory often distinguish between two subsystems: visual and auditory. The objective of this study was to examine the relationship between different measures of working memory on Visual Puzzles (VP) performance. We predict that Symbol Span and Spatial Span, as measures of visual working memory, will be strong predictors of VP performance whereas Digit Span, a measure of auditory working memory, will not. Method: Data from 61 patients (37 males, 24 females) seen for an outpatient neuropsychological evaluation were included with an average age of 51.01±4.94 and 13.67±1.88 years of education. Regression analysis, correlational analyses, and paired t-test were used. Results: The regression analysis indicated that Spatial Span and Symbol Span were significant predictors of VP, explaining 36% of the variance R2 = 0.362, F(4, 60) = 7.927, p < 0.001. Age and Education were also significant predictors for VP, but explained only 7% of the...
