Visual-spatial and verbal-spatial binding in working memory

The asymmetric pattern of binding of features in working memory is a controversial topic in the literature. The binding of visual- spatial and verbal-spatial information was studied in a serial recognition task to address the contribution of spatial location, visual appearance, and verbal identity to binding in working memory. The participants (n = 32) made a recognition judgment of two sequences of four stimuli each based on a relevant dimension while ignoring changes in an irrelevant dimension. In the visual and verbal tasks, the location was irrelevant. In the spatial tasks, the visual or v...
