Maintenance versus manipulation in verbal working memory revisited: an fMRI study.

Working memory (WM) is the ability to keep a limited amount of information "on line" for immediate use during short intervals. Verbal WM has been hypothesized to consist of neuroanatomically segregated components, i.e., maintenance (storage, rehearsal, ...

Differential cortical activation during voluntary and reflexive saccades in man.

A saccade involves both a step in eye position and an obligatory shift in spatial attention. The traditional division of saccades into two types, the "reflexive" saccade made in response to an exogenous stimulus change in the visual periphery and the ...

Measurement of the visual field.

There is increasing evidence that concurrent visual and nonvisual tasks not only reduce the size but also result in systematic deformation of the visual field. Given such complex changes in the visual field, appropriate representation and measurement of ...

Lexical access without attention? Explorations using dichotic priming.

The authors used lexical decision in a dichotic listening situation and measured identity priming across channels to explore whether unattended stimuli can be processed lexically. In 6 experiments, temporal synchronization of prime and target words was ...

Inhibition and anticipation in visual search: evidence from effects of color foreknowledge on preview search.

We present four experiments in which we examined the effects of color mixing and prior target color knowledge on preview search (Watson & Humphreys, 1997). The task was to detect a target letter (an N or a Z) that appeared along with other new letters, ...

Does partial difficult search help difficult search?

Olds, Cowan, and Jolicoeur (2000a, 2000b) showed that exposure to a display that affords pop-out search a target among distractors of only one color) can assist processing of a related display that requires difficult search. They added distractors of an ...

Does auditory streaming require attention? Evidence from attentional selectivity in short-term memory.

R. P. Carlyon, R. Cusack, J. M. Foxton, and I. H. Robertson (2001) have argued that attention is crucial for auditory streaming. The authors review R. P. Carlyon et al.s (2001) arguments and suggest that a pertinent literature, the irrelevant sound ...

Sources of interference in the attentional blink: target-distractor similarity revisited.

Observers monitored streams of words or letters (10 items/sec) for one or two targets. An attentional blink (AB) effect was observed in which identification of the first target temporarily impaired identification of the second target. Target ...

Top-down control over biased competition during covert spatial orienting.

Larger benefits of spatial attention are observed when distractor interference is prevalent, supporting the view that spatial selection facilitates visual processing by suppressing distractor interference. The present work shows that cuing effects with ...

A tool for tracking visual attention: the Restricted Focus Viewer.

Eye-tracking equipment has proven useful in examining the cognitive processes people use when understanding and reasoning with visual stimuli. However, eye-tracking has several drawbacks: accurate eye-tracking equipment is expensive, it is often awkward ...
