Healthy and fibromyalgia volunteers performed the same on a working memory task.

BOLD brain measurements during the working task were also the same between groups.

Accuracy was related to cognitive appraisal in healthy volunteers but not in fibromyalgia.

Cognitive appraisal correlated with different patterns of BOLD activity in each group.

The feeling of cognitive impairment appears to be functionally separate from task performance.
