Paradigm overview
Operation Span measures complex working memory by combining simple arithmetic verification with serial letter recall. Scores include absolute span, partial span, and math accuracy validity context.
Key scoring outputs
Absolute Span Score
countLetters from perfectly recalled sets.
Higher is better
Partial Span Score
countLetters recalled in the correct serial position.
Higher is better
Math Accuracy
proportionAccuracy on the processing component.
Higher supports validity
