Reaction Time

The effect of attentional cueing on conscious awareness of stimulus and response.

Attending to a cued location in space leads to faster reaction times when a stimulus is presented there. The reasons for this attentional effect, and its specific locus in the information-processing chain between stimulus and response, remain unclear. ...

Direct parameter specification of an attention shift: evidence from perceptual latency priming.

In the direct parameter specification (DPS) mode of sensorimotor control, response parameters can be specified by stimuli that are not consciously perceived [Psychological Research/Psychologische Forschung 52 (1990) 207]. DPS is contingent on the current ...

The what and where in visual masking.

A metacontrast mask suppresses the visibility of, without influencing the reaction time (RT) to, the target. We investigated whether this dissociation results from a sensori-motor pathway immune to masking effects or from the characteristics of stimulus ...

The role of spatial attention in the processing of facial expression: an ERP study of rapid brain responses to six basic emotions.

To investigate the time course of emotional expression processing, we recorded ERP responses to stimulus arrays containing neutral versus angry, disgusted, fearful, happy, sad, or surprised faces. In one half of the experiment, the task was to ...

Two stages in crossmodal saccadic integration: evidence from a visual-auditory focused attention task.

Saccadic reaction time (SRT) toward a visual target stimulus was measured under simultaneous presentation of an auditory non-target (accessory stimulus). Horizontal position of the target was varied (25 degrees left and right of fixation) as well as ...

Reaction time analysis of two types of motor preparation for speech articulation: action as a sequence of chunks.

Reaction time (RT) prior to speech articulation increased as a function of response complexity. The RT findings formed 2 patterns, each of which was a different Response Complexity x Paradigm (choice RT vs. simple RT) interaction. That result extends ...

Semantic and cross-case identity priming in patients with Parkinsons disease.

Semantic and cross-case identity priming were investigated in nondemented patients with Parkinsons disease (PD) and controls using the Lexical Decision Task. Three conditions were administered that consisted of the presentation of prime and target word ...

Evidence for lasting sequence segmentation in the discrete sequence-production task.

It is well known that movement sequences are initiated and executed more slowly as they become longer. Those effects of sequence length, which have been found to lessen with practice, have been attributed to the development of a single motor chunk that ...

Distinct spatial frequency sensitivities for processing faces and emotional expressions.

High and low spatial frequency information in visual images is processed by distinct neural channels. Using event-related functional magnetic resonance imaging (fMRI) in humans, we show dissociable roles of such visual channels for processing faces and ...

Perceiving numbers causes spatial shifts of attention.

Number symbols are part of our everyday visual world. Here we show that merely looking at numbers causes a shift in covert attention to the left or right side, depending upon the numbers magnitude. This observation implies obligatory activation of number ...
