Figure 4.

A stimulus-generalization/response-strength portrayal of performance in a temporal-duration discrimination with a third response sometimes allowed and directly rewarded. The horizontal axis indicates the subjective impression of the trial. The solid line instantiates the idea that the directly rewarded third response would have a constant response strength or attraction across the range of trial levels. The otted lines instantiate the idea that response strength for the Short and Long responses would wane exponentially going inward away from the task’s anchors (Level 1 and Level 71).
