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.
| Sleep Deprived (4 hours sleep) | Fully Rested (8 hours sleep) |
