The delayed memory portion of the sVOLT tasj.

In the first part of this test, participants were shown 10 three-dimensional Euclidean shapes that they were asked to identify for immediate recall (sVOLT . Now, during the delayed recall (sVOLTd , participants are shown a series, one at a time, of 20 three-dimensional Euclidean shapes - the 10 shapes they were asked to memorize during the SVOLT mixed with 10 novel shapes. The participant’s task is to decide whether he/she has seen the shape before by clicking with the mouse on one of four buttons: “DEFINITELY YES”, “PROBABLY YES”, "PROBABLY NO" and "DEFINITELY NO". (NOTE: The original sVOLT had only two response choices: “YES I have seen the shape” and “NO I have not seen the shape.” . Participants have 20 seconds to select a response before the test moves on to the next trial. There are two forms of the sVOLTd: the sVOLTd-A and sVOLTd-B.

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).
