@article{6067, abstract = {{Implicit change detection demonstrates how the visual system can benefit from stored information that is not immediately available to conscious awareness. We investigated the role of motor action in this context. In the first two experiments, using a one-shot implicit change detection paradigm, participants responded to unperceived changes either with an action (jabbing the screen at the guessed location of a change) or with words (verbal report), and sat either 60 cm or 300 cm (with a laser pointer) away from the display. Our observers guessed the locations of changes at a reachable distance better with an action than with a verbal judgment. At 300 cm, beyond reach, the motor advantage disappeared. In experiment 3, this advantage was also unavailable when participants sat at a reachable distance but responded with hand-held laser pointers near their bodies. We conclude that a motor system specialized for real-time visually guided behavior has access to additional visual information. }}, author = {{Tseng, Philip and Tuennermann, Jan and Roker-Knight, Nancy and Winter, Dorina and Scharlau, Ingrid and Bridgeman, Bruce}}, issn = {{0301-0066}}, journal = {{Perception}}, keywords = {{implicit change detection, action perception, visual system, perceptual judgment, verbal fluency, Analysis of Variance, Awareness, Female, Humans, Male, Psychomotor Performance, Random Allocation, Reaction Time, Visual Perception, Visual Memory, Visual Stimulation, Implicit Memory, Judgment, Perceptual Discrimination}}, number = {{10}}, pages = {{1311 -- 1321}}, title = {{{Enhancing implicit change detection through action.}}}, volume = {{39}}, year = {{2010}}, } @article{6083, abstract = {{How fast can information of a first target (T1) in a rapid serial visual presentation be used for top-down allocation of attention in time?

Masked primes preceded one of the targets. The primes were either similar to the targets or not, in shape, or in color.
