The Preservation of Cued Recall in the Acute Mentally Fatigued State- A Randomised Crossover Study
Europe |
A randomised crossover study involving twenty healthy medical students assessed free (presentation) and cued (MCQ) recall of clinical case histories at 0 and 2hrs under low and high cognitive load settings using the N-Back task.

Unpublished
Free recall is significantly impaired by increased cognitive load (p<0.05) with subjects demonstrating perceived mental fatigue during the high cognitive load assessment. There was no significant difference in the amount of information retrieved by cued recall under high and low cognitive load conditions (p =1).
