Paradigm overview
The Dimensional Change Card Sort measures cognitive flexibility by asking participants to match a target card to one of two response cards while the relevant rule changes between color and shape.
In this browser-native implementation, participants see two fixed response cards and a bivalent target card. A rule cue tells them whether to match by color or by shape. Scored blocks include color-rule trials, shape-rule trials, and a mixed block with repeat and switch trials.
Key scoring outputs
Overall Accuracy
proportionProportion of scored card-sort trials answered correctly.
Higher is better
Mixed-Block Accuracy
proportionAccuracy during the mixed block where the sorting rule can repeat or switch.
Higher is better
Switch Accuracy
proportionAccuracy on mixed-block trials where the rule changed from the previous trial.
Higher is better
Repeat Accuracy
proportionAccuracy on mixed-block trials where the same rule repeated.
Higher is better
Switch Cost RT
msDifference between correct switch-trial RT and correct repeat-trial RT in the mixed block.
Lower is better when accuracy is adequate
Alternate-Rule Errors
countIncorrect responses that matched the card that would have been correct under the other rule.
Lower is better
Practice Pass
0/1Indicates whether practice accuracy reached the configured readiness threshold.
1 indicates practice readiness
