Differential frontal involvement in shifts of internal and perceptual attention.
BACKGROUND Perceptual attention enhances the processing of items in the environment, whereas internal attention enhances processing of items encoded in visual working memory. In perceptual and internal attention cueing paradigms, cues indicate the to-be-probed item before (pre-cueing) or after (retro-cueing) the memory display, respectively. Pre- and retro-cues confer similar behavioral accurac...
متن کاملDissecting the brain's internal clock: how frontal-striatal circuitry keeps time and shifts attention.
The ability of organisms to time and coordinate temporal sequences of events and to select particular aspects of their internal and external environments to which they will attend is vital to the organism's ability to adapt to the world around them. Numerous psychological theories have been proposed that describe how organisms might accomplish such stimulus selection and represent discrete temp...
متن کاملThe mental wormhole: internal attention shifts without regard for distance.
Attention operates perceptually on items in the environment, and internally on objects in visuospatial working memory. In the present study, we investigated whether spatial and temporal constraints affecting endogenous perceptual attention extend to internal attention. A retro-cue paradigm in which a cue is presented beyond the range of iconic memory and after stimulus encoding was used to mani...
متن کاملAttention and perceptual organization
How does attention contribute to perceptual experience? Within cognitive science, attention is known to contribute to the organization of sensory features into perceptual objects, or ‘‘object-based organization.’’ The current paper tackles a different type of organization and thus suggests a different role for attention in conscious perception. Within every perceptual experience we find that mo...
متن کاملAttention and Perceptual Learning
Perceptual learning as a phenomenon. We are all of us experts. Each one of us is able to effortlessly distinguish between a large number of people that we encounter in our everyday lives. When considered as stimuli in the abstract this is a difficult discrimination task as the stimuli are all rather similar to one another, yet we can identify an individual in a moment with an accuracy that woul...
