英文摘要 |
PURPOSE: The manipulation of visual working memory (VWM) has received increasing interest, by focusing on the underlying mechanisms of manipulation for objects presented at distinct locations. However, no study has explored the manipulation mechanisms for the content of a stored multi-featured object (e.g., retaining color while discarding polygon for a colored-polygon). The current study examined whether participants can selectively retain task-relevant information of a dual-featured object after a retro-cue was presented at the maintenance interval. We hypothesized that the processing nature of a feature at the perceptual stage affected its manipulation in VWM, and tested this hypothesis by adopting two types of dual-featured objects. One is objects composed of highly-discriminable features (colored-oriented-bars) which can be processed via spread attention; the other type is objects containing fine-grained information (colored-polygons) which is processed via focal attention. We predicted that selective maintenance could not occur for the former type but occurred for the latter. |
