Which of the following is an example of a stimulus generalization?
The Correct Answer and Explanation is :
Example of Stimulus Generalization:
Imagine a child who has been bitten by a dog. After this incident, the child becomes fearful not just of that specific dog but also of all dogs they encounter, regardless of their size, breed, or demeanor. This reaction is an example of stimulus generalization.
Explanation:
Stimulus generalization is a fundamental concept in classical conditioning, first introduced by psychologist Ivan Pavlov. It occurs when an organism responds to stimuli that are similar but not identical to the conditioned stimulus that elicited the original response. In the case of the child who was bitten, the conditioned stimulus is the specific dog that caused the fear. The child’s fear response (the unconditioned response) was initially directed towards that dog. However, due to the experience, the child begins to associate the fear not only with the specific dog but also with all dogs in general.
This phenomenon can be understood through the lens of learning and adaptation. Generalization allows organisms to respond appropriately to new but similar stimuli in their environment, which can be beneficial for survival. In the wild, for instance, if an animal learns to fear a specific predator, generalizing that fear to all similar predators increases its chances of survival.
In everyday life, stimulus generalization can manifest in various ways. For instance, a person who has had a negative experience with a particular brand of food might develop an aversion to similar brands, or someone who has experienced trauma in one environment may feel anxiety in all similar environments. While this generalization can serve as a protective mechanism, it can also lead to irrational fears or phobias if not properly addressed. Understanding stimulus generalization is crucial in therapeutic settings, particularly in treating anxiety disorders, where therapists help individuals differentiate between stimuli and reduce unwarranted fear responses.
