a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
A task in which subjects are presented with a stream of letters, and must respond to one of the letters and refrain from responding to any other letters. The Penn Continuous Performance Test (PCPT) uses a standard CPT paradigm. The participant responds to a set of 7-segment displays presented 1/sec., whenever they form a digit (NUMBERS, initial 3 min) or letter (LETTERS, next 3 min). The number of true positive responses is recorded as the accuracy score and the median response time for true positive responses is the measure of attention speed.

CONDITIONS

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

CONTRASTS

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

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).
