In an exploratory analysis, we applied the marginal value theorem (MVT) which describes the optimal behavior in patch-foraging decisions. Although the purpose of our study was not to assess whether participants used an optimal strategy, but to examine group differences in the use of information given by the task, the MVT may provide additional insights into participants behavior. Originally stated in animal literature, it assumes that an individual should leave the current option when the return falls below the average return in the environment [The immediate expected reward Therefore,
