Answer:
Conditioned response
Step-by-step explanation:
In classical conditioning, a conditioned response is a learned behavior or response that is elicited when an unconditioned stimulus become associated with a neutral stimulus that is now acting as a conditioned stimulus.
In the consumer behavior context, the new brand of conditioner is the conditioned stimulus that became associated with the shampoo that is produced by the same brand. The brand of shampoo is the unconditioned stimulus.
The behavior of the consumer purchasing a conditioner because they believe it has the same attributes associated with shampoo produced by the same brand, is an example of conditioned response.
