Figure 2.

Screenshot of the Fishing task (Czienskowski, 2005a). The fisherman is moving the float at the end of the fishing line toward a fish that appeared on the left-hand side of the pond. Three fish have already been caught at the current pond (see resource stack on the right side). Subjects can choose to move to the next pond at any time by hitting the red switch patch button (lower right). Hitting the switching button will let the fisherman walk off the screen, initiate a waiting period in which a bouncing ball animation is shown (i.e., the travel time between subsequent ponds), and ends with the fisherman walking back onto the screen to a new pond (with a centered float, no fish showing in the bucket, an emptied resource stack, and the pond redrawn with different pond margins and vegetation around it).
