Variability in performance: identifying early signs of future cognitive impairment.

abstract：:Two characteristics of word-list generation performance are forming clusters (i.e., contiguous words from the same subcategory) and switching among them. Patients with frontal lobe pathology show reduced switching on letter-cued word generation tasks, and clustering has been associated with temporal lobe functioning. ...
