Answer:
stimulus generalization
Explanation:
Stimulus generalization is the phenomenon in which stimulus similar to the original stimulus tends to produce a similar response. This theory determines how a similar stimulus evokes similar responses in a learning paradigm. For example, if a child is conditioned to fear from a fruit he would tend to fear from similar fruits even if the physical properties of the fruit are not the same.
As per the question, Kerry's behavior to fear from similar stimulus reflects stimulus generalization.
