Definitions:

Operants

Behaviors that are controlled or modified by their consequences, such as rewards or punishments, in the context of operant conditioning.

Reinforcers

Stimuli that, when presented after a behavior, increase the likelihood of that behavior occurring again in the future.

Instrumental Conditioning

A form of learning in which the participant receives a reinforcer only after performing the desired response, and thereby learns a relationship between the response and the reinforcer.

Correct Responses

Correct responses refer to answers or reactions that are accurate, appropriate, or in alignment with expected outcomes in a given context.
