Research Abstract |
In order to optimize their foraging, animals should not attack all of the food they encountered. Instead, they must choose based on the evaluation of food items by the profitability, which is product of the amount and the proximity of the each food. It is however not uniquely determined, but is highly context-dependent, as to if priority should go to the amount or the proximity. It has been shown that experience of competitive foraging in group of individuals lead to enhanced impulsiveness so that newly hatched chicks made proximity-oriented choices. We also found that the competitive foraging suppresses the neuronal signals that represent anticipated food reward. The suppressive process is supposed to be involved in the control of temporal discounting.
