An Experimental Study On The Relationships Between Visuospatial Ability And Working Memory Span Of College Students

This study tested 514 high school students with visuospatial working memory span, digital working memory span, localization, form completion, mental rotation-3D and touching blocks tests. Through researching their relationships, we hope to explore whether the working memory capacity has domain generality.The results show that:(l)There are significant differences among the students from different subjects in touching blocks,form completion and visuospatial working memory span tests; The scores of boys in localization, touching blocks and visuospatial working memory span tests are significantly higher than that of girls; The form completion scores of students living in city are significantly higher than who living in country, and there are no significant differences among the students from different places in working memory span tests.(2)The localization and form completion tests focus on spatial orientation ability, whereas the mental rotation-3D and touching blocks tests attend to spatial visualization ability.(3)The working memory capacity has domain generality, but in special aspect it shows domain specificity. The localization,mental rotation-3D, touching blocks tests and visuospatial working memory span are significantly related; The localization, touching blocks tests and digital working memory span suggest a significant relation. The visuospatial working memory span can predict scores of localization,mental rotation-3D, touching blocks tests; The digital working memory span is found to be able to predict scores of localization and touching blocks tests.
