Cognitive Flexibility (Task Switching, WCST, Alternative Uses)
Short name: Cognitive Flexibility · Introduced 1948 · Berg, Jersild, Guilford
Tasks measuring the ability to shift mental sets and generate divergent solutions.
What it measures
Rapid reconfiguration of task rules, perspectives, or response strategies - a core component of creativity and adaptive behavior.
Format
Task-switching paradigms measure 'switch cost' between rule sets. WCST measures rule-shift adaptation. Alternative Uses asks for as many uses for a common object as possible (divergent thinking).
Scoring
Switch cost (ms difference between switch and repeat trials), perseverative errors, originality and fluency scores.
Notable results
- Switch costs are universal across cultures and ages.
- Cognitive flexibility declines with normal aging and in Parkinson's disease.
- Trains modestly with practice; near-transfer is reliable, far-transfer contested.
Strengths
- Bridges cognitive control and creativity research.
- Sensitive to dopaminergic function.
Limitations
- Divergent-thinking scoring is subjective.
- Switch costs vary substantially with task pairing.
