The generalization gradient obtained through testing following S+/S- discrimination learning in Exercise 44, using tones of 2.0 kHz (S+) and 2.25 kHz (S-), had its maximum at __________ kHz and minimum (minima) at __________ kHz.
a. 2.0; 2.25
b. 2.0; 2.5
c. 1.75; 1.0 and 2.0
d. 1.75; 1.0 and 2.25
d. 1.75; 1.0 and 2.25
Answer feedback: The generalization gradient had a maximum displaced from the S+ used during training. It was displaced in the direction away from the S- used during training. The maximum occurred at 1.75 kHz. Minima were at 1.0 and 2.25 kHz as well as the stimuli greater than 2.25 kHz.
