Concept information
Preferred term
Compensation Related Utilization of Neural Circuits Hypothesis
Definition
- "CRUNCH proposes that during task performance, as task difficulty (or load) increases, more cortical regions will be activated. Older adults reach their load capacity sooner than younger adults, so at easy and intermediate levels of task difficulty, they will recruit more neural resources than younger adults – the classic ‘compensation’ effect. At higher levels of load, the compensatory mechanism is no longer effective, leading to less activation and poorer performance in older vs. younger adults." (Jamadar, 2020, p. 2).
