Abstract
Visual working memory (VWM) has been implicated both in the online representation of object tokens (in the object-file framework) and in the top-down guidance of attention during visual search, implementing a feature template. It is well established that object representations in VWM are structured by location, with access to the content of VWM modulated by position consistency. In the present study, we examined whether this property generalizes to the guidance of attention. Specifically, in two experiments, we probed whether the guidance of spatial attention from features in VWM is modulated by the position of the object from which these features were encoded. Participants remembered an object with an incidental color. Items in a subsequent search array could match either the color of the remembered object, the location, or both. Robust benefits of color match (when the matching item was the target) and costs (when the matching items was a distractor) were observed. Critically, the magnitude of neither effect was influenced by spatial correspondence. The results demonstrate that features in VWM influence attentional priority maps in a manner that does not necessarily inherit the spatial structure of the object representations in which those features are maintained.Entities:
