The study investigates the relationship between attention deficits and foraging behavior in humans. Participants were asked to collect berries in an online task, choosing between staying at a depleting patch or moving to a new one. The task was designed to test optimal foraging theory, which predicts that individuals should leave a patch when local intake rates fall below the average for the environment. Participants also completed an ADHD self-report screening assessment. Results showed that participants left patches sooner when travel times between patches were shorter, as predicted by optimal foraging theory. However, participants who screened positive for ADHD left patches significantly sooner and achieved higher reward rates than those who did not meet the ADHD criteria. This suggests that ADHD-like traits may confer foraging advantages in certain environments, possibly due to heightened exploration and impulsivity. The findings have implications for understanding the adaptive function of ADHD in human populations.The study investigates the relationship between attention deficits and foraging behavior in humans.
