Question

regarding operant conditioning, what does reinforcement do?
weakens behavior by adding unpleasant stimuli or removing pleasant stimuli
enables unconditioned stimulus and conditioned stimulus to be effective

Explanation:

In operant conditioning, reinforcement strengthens a behavior. Positive reinforcement adds a pleasant stimulus and negative reinforcement removes an unpleasant stimulus to increase the likelihood of a behavior being repeated. The first option describes punishment, not reinforcement. The second option is related to classical - conditioning concepts. The third option is about memory - related mental operations, not reinforcement in operant conditioning.

None of the provided options are correct. Reinforcement strengthens behavior by adding pleasant stimuli (positive reinforcement) or removing unpleasant stimuli (negative reinforcement).
