6.1.6. Non persistence of a consummatory action in the presence of an aversive stimulus
In this experiment we will test the non persistence of a consummatory action (eat) of a
prey animat in the presence of a predator. We have an initial state as the one shown in Figure
39: a hungry prey animat, perceiving a food source, but not perceiving a thirsty predator that
is nearby. The prey animat perceives the predator while he is eating, and runs away before he
satiates his hunger completely, as seen in Figure 40.

Figure 39. Initial state of the experiment. Figure 40. The prey animat runs away before
satiating his hunger.
Afterwards, the prey animat perceived another food source, which he was able to satiate
his thirst with, as seen in Figure 41. We used a value of 6 equal to 0.9. Otherwise, the
persistence would have been enough to satiate the hunger of the prey animat. If the prey
animat would eat slower, with a usual value of 6 we would have obtained similar results.

hunger with another food source.
