A year after surviving a major car accident at a highway on-ramp,Kim-Li still responds with terror when he enters a highway ramp.This reaction best illustrates

A) an unconditioned response.
B) operant conditioning.
C) discrimination.
D) generalization.

Generalization is when a person responds to similar stimuli in the same way as the original stimulus. In this case, Kim-Li's fear of highway on-ramps is a response to the similar stimuli of highway ramps in general, indicating generalization. The fear was conditioned by the original car accident, so it is not an unconditioned response. Operant conditioning involves learning through consequences and does not apply in this situation. Discrimination is the ability to differentiate between similar stimuli and is not demonstrated in this scenario.
