Parents often experience cognitive fatigue after a day of caring for their children, which can make even simple tasks like preparing dinner feel overwhelming. This mental exhaustion affects decision-making and motivation, as shown in research by Johns Hopkins University and the Kennedy Krieger Institute. The study used fMRI to observe brain activity in 28 participants performing memory tasks. As they became more fatigued, participants were less likely to choose challenging tasks, even when higher rewards were offered. This suggests that cognitive fatigue impacts how people weigh effort against potential rewards, highlighting the brain’s role in decision-making when tired.
