PEBL Perceptual Vigilance Task TASK
Unreviewed

This task measures sustained attention and reaction time. A light blinks randomly and the subject is asked to press a button when the they see it. The focus is not on how quickly the subject notices the light, but how often the subject doesn't notice the light. It is often used to study the effects of sleep deprivation and sleep debt.

CONDITIONS

Experimental conditions are the subsets of an experiment that define the relevant experimental manipulation.

CONTRASTS
commissions (false positives)(edit)
omissions(edit)
reaction time(edit)

In the Cognitive Atlas, we define a contrast as any function over experimental conditions. The simplest contrast is the indicator value for a specific condition; more complex contrasts include linear or nonlinear functions of the indicator across different experimental conditions.

INDICATORS
attention vigilance

An indicator is a specific quantitative or qualitative variable that is recorded for analysis. These may include behavioral variables (such as response time, accuracy, or other measures of performance) or physiological variables (including genetics, psychophysiology, or brain imaging data).
