英文摘要 |
PURPOSE: Over the past decade, it has been debated whether retaining bindings in working memory (WM) requires more attention than retaining constituent features, focusing on domain-general attention and space-based attention. Recently we proposed that retaining bindings in WM needs more object-based attention than retaining constituent features (Gao et al., 2017; Shen, Huang, & Gao, 2015). However, the composed features in the tested bindings all belong to separable feature dimensions. It has been suggested that there are two types of feature relations: Separable features (e.g., color and shape in a colored shape) and integral features (e.g., width and height of a rectangle). While our brain encodes separable features independently, it is difficult to encode the integral features separately. Consequently, the object-based attention hypothesis of retaining bindings in WM may be constrained to separable features, and retaining bindings of integral features does not require more object-based attention than the constitute single features. |
