Final answer:
Learned response generalization is when a learned response is demonstrated to stimuli that are similar to the original conditioned stimulus. An example is a dog salivating to similar tones after being conditioned to salivate to a specific tone.
Step-by-step explanation:
The definition of learned response generalization based on minimal physical similarity or responses refers to the process by which a learned response is demonstrated to stimuli that are similar to the original conditioned stimulus. In other words, the organism responds to similar stimuli as it would to the original stimulus. This is the opposite of stimulus discrimination, where the organism responds differently to similar stimuli. An example of learned response generalization is when a dog that has been conditioned to salivate in response to a specific tone also salivates to similar tones that are slightly different in pitch or frequency.
