The fate of task-irrelevant visual motion: perceptual load versus feature-based attention.
We tested contrasting predictions derived from perceptual load theory and from recent feature-based selection accounts. Observers viewed moving, colored stimuli and performed low or high load tasks associated with one stimulus feature, either color or motion. The resultant motion aftereffect (MAE) was used to evaluate attentional allocation. We found that task-irrelevant visual features receive...
متن کاملAttention alters feature space in motion processing.
Attending to a particular feature modulates the activity of neurons throughout the visual field with the result that relevant features are enhanced while irrelevant features are suppressed. Do these modulatory influences merely lead to a gating of relevant features, or does attention have a direct impact on the representation of feature space, leading to a different percept depending on the con...
متن کاملTask-irrelevant learning occurs only when the irrelevant feature is weak
The role of attention in perceptual learning has been controversial. Numerous studies have reported that learning does not occur on stimulus features that are irrelevant to a subject's task [1,2] and have concluded that focused attention on a feature is necessary for a feature to be learned. In contrast, another line of studies has shown that perceptual learning occurs even on task-irrelevant f...
متن کاملCorrelation Based Feature Selection with Irrelevant Feature Removal
For a broad-topic and ambiguous query, different users may have different search goals when they submit it to a search engine. The inference and analysis of user search goals can be very useful in improving search engine relevance and user experience. A feature selection algorithm may be evaluated from both the efficiency and effectiveness points of view. While the efficiency concerns the time ...
متن کاملRepetition priming in visual search: episodic retrieval, not feature priming.
Previous research has shown that when the targets of successive visual searches have features in common, response times are shorter. However, the nature of the representation underlying this priming and how priming is affected by the task remain uncertain. In four experiments, subjects searched for an odd-sized target and reported its orientation. The color of the items was irrelevant to the ta...
