same-different task TASK
Unreviewed

A task which assesses shifting attention. In the computerized version of this task, three spaceships appear on a screen and the participant must determine if the spaceships are all different or all the same. The spaceships can differ in color, size, or shape type. There are three levels of difficulty. In the first level, the spaceships must all be identical to be considered the same. In the second level of difficulty, the spaceships are considered the same even if they only share two qualities, and in the third difficulty level, the spaceships only need to share one quality to be considered the same. Auditory feedback is given after each response notifying the child whether their answer was correct.

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
reaction time
errors
number of correct responses

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).
