a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
A variant of the n-back task, each trial consists of letters (b,d,g,t,v) presented in successive order. Subjects must press a button if the current letter matches the letter that occurred n trials ago (regardless of capitalization). N varies according to a staircase tracking method that increases as subjects accurately respond and decrease as subjects make errors.

CONDITIONS
No conditions have yet been associated.


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

CONTRASTS
No contrasts have yet been associated.


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
No indicators have yet been associated.


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).


User Discussion


"Are stimuli for this task limited to letters? Should this be a descendant of the letter n-back task or the n-back task?"
