Question 64

Dr. Vance's Cognitive Flexibility Study

Dr. Elizabeth Vance conducted an experiment to investigate the effect of sleep deprivation on cognitive flexibility. Participants were randomly assigned to either a 'Sleep Deprived' condition (4 hours of sleep) or a 'Fully Rested' condition (8 hours of sleep) before completing a computerized rule-shifting task. The number of perseverative errors was recorded for each participant, where a higher score indicates poorer cognitive flexibility.
