Visual working memory contaminates perception.
Indirect evidence suggests that the contents of visual working memory may be maintained within sensory areas early in the visual hierarchy. We tested this possibility using a well-studied motion repulsion phenomenon in which perception of one direction of motion is distorted when another direction of motion is viewed simultaneously. We found that observers misperceived the actual direction of m...

activated portion of the information in permanent memory, which extends beyond the focus of attention to include some automatically activated information (see Fig. 1). When researchers use the term 'working memory', some of them seem to be referring only to the focus of attention, whereas others seem to be referring to all of the temporarily activated information. It is also likely that certain...
متن کاملVisual Working Memory Capacity and Proactive Interference
BACKGROUND Visual working memory capacity is extremely limited and appears to be relatively immune to practice effects or the use of explicit strategies. The recent discovery that visual working memory tasks, like verbal working memory tasks, are subject to proactive interference, coupled with the fact that typical visual working memory tasks are particularly conducive to proactive interference...
متن کاملAccounting for stimulus-specific variation in precision reveals a discrete capacity limit in visual working memory.
If we view a visual scene that contains many objects, then momentarily close our eyes, some details persist while others seem to fade. Discrete models of visual working memory (VWM) assume that only a few items can be actively maintained in memory, beyond which pure guessing will emerge. Alternatively, continuous resource models assume that all items in a visual scene can be stored with some pr...
متن کاملDiscrete capacity limits in visual working memory.
The amount of information we can actively maintain 'in mind' is very limited. This capacity limitation, known as working memory (WM) capacity, has been of great interest because of its wide scope influence on the variety of intellectual abilities. Recently, there has been an ongoing debate about how this capacity should be best characterized. One viewpoint argues that WM capacity is allocated i...
