The optimal time window of visual–auditory integration: a reaction time analysis [PDF]

Frontiers in Integrative Neuroscience, 2010
THE SPATIOTEMPORAL WINDOW OF INTEGRATION HAS BECOME A WIDELY ACCEPTED CONCEPT IN MULTISENSORY RESEARCH: crossmodal information falling within this window is highly likely to be integrated, whereas information falling outside is not. Here we further probe this concept in a reaction time context with redundant crossmodal targets. An infinitely large time

Stimulus saliency modulates pre-attentive processing speed in human visual cortex [PDF]

, 2011
The notion of a saliency-based processing architecture [1] underlying human vision is central to a number of current theories of visual selective attention [e.g., 2].

Reaction time in a visual 4-choice reaction time task: ERP effects of motor preparation and hemispheric involvement [PDF]

, 2016
Reaction time (RT), the most common measure of CNS efficiency, shows intra- and inter-individual variability. This may be accounted for by hemispheric specialization, individual neuroanatomy, and transient functional fluctuations between trials.

Age differences in intra-individual variability in simple and choice reaction time: systematic review and meta-analysis [PDF]

, 2012
<p>Background: Intra-individual variability in reaction time (RT IIV) is considered to be an index of central nervous system functioning. Such variability is elevated in neurodegenerative diseases or following traumatic brain injury. It has also

Salience-based selection: attentional capture by distractors less salient than the target [PDF]

, 2013
Current accounts of attentional capture predict the most salient stimulus to be invariably selected first. However, existing salience and visual search models assume noise in the map computation or selection process.

Reaction time to change in visual orientation [PDF]

Perception & Psychophysics, 1972
The aftereffects of viewing diagonal lines for 50, 500, and 1,000 msec were measured by the speed and accuracy of identification of a variably tilted test grating. Significant RT and tilt aftereffects were found as functions of the duration of orientation-specific adaptation and the angle of separation between inspection and test lines.

Classical reaction time and anticipation reaction time in a simple visual reaction time task [PDF]

, 1973
The purpose of the study was to investigate performance on anticipation reaction time and classical reaction time as a function of practice. In the anticipation reaction time condition, the foreperiod was held constant, while in the classical reaction ...

Callosal connections of primary visual cortex predict the spatial spreading of binocular rivalry across the visual hemifields [PDF]

, 2011
In binocular rivalry, presentation of different images to the separate eyes leads to conscious perception alternating between the two possible interpretations every few seconds. During perceptual transitions, a stimulus emerging into dominance can spread

CONTRAST AS SEEN IN VISUAL SEARCH REACTION TIMES [PDF]

Journal of the Experimental Analysis of Behavior, 1989
Three pigeons searched arrays of alphabetic letters displayed on computer monitors. On each trial, either an A or an E appeared, and the reaction time and accuracy with which the bird pecked at this target were measured. In each block of trials, each target (A or E) was displayed alone, or together with a number of distractor letters (2 or 18) that ...

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.
