Final answer:
In the case of a child fearing only bees and not other flying insects after a bee sting, the behavior is known as stimulus discrimination, which is part of classical conditioning in psychology.
Step-by-step explanation:
The fear of bees and no other type of flying insect that the child developed after being stung by a bee is an example of stimulus discrimination. This occurs in classical conditioning, a type of associative learning where an organism learns to respond only to a specific stimulus and not to other similar stimuli. In contrast, stimulus generalization would have the child fearing all types of flying insects, as they would be similar to the conditioned stimulus of the bee.
