Popis: It has been indicated that visual search is interfered with in spatial working memory (WM), although not in nonspatial WM. In this study, the effects on visual search of individual differences in spatial and nonspatial WM were examined. Two visual search conditions were used: a conjunction search condition comprising two features (color and shape) and a disjunction condition comprising only one feature (color or shape). 96 participants (42 men, 54 women, M age = 20.9 yr., SD = 3.5) participated in this study. The participants were divided into high and low WM groups based on their spatial and nonspatial WM test scores. As a result, statistically significant group differences in the conjunction search rate were observed in spatial WM but not in nonspatial WM. These results suggest there is a relationship between visual search and the individual spatial WM ability, but this does not hold for nonspatial WM.
