Operant and Observational Learning

Operant Conditioning and Observational Learning

By the end of this lesson, you will be able to apply operant conditioning principles to real-world situations, analyze schedules of reinforcement, and explain Bandura's observational learning theory.

Operant Conditioning: The Core Distinction

Reinforcement: any consequence that increases the frequency of the behavior that preceded it.

Punishment: any consequence that decreases the frequency of the behavior that preceded it.

Positive: adding a stimulus.

Negative: removing a stimulus.

	Adds a stimulus	Removes a stimulus
Increases behavior	Positive reinforcement	Negative reinforcement
Decreases behavior	Positive punishment	Negative punishment

Critical point: "negative reinforcement" strengthens behavior (it removes something aversive). It is NOT punishment. This is one of the most confused distinctions in all of psychology.

Examples to Memorize

Positive reinforcement: you study hard → get an A → you study hard again (A added, studying increased)

Negative reinforcement: you take aspirin (behavior) → headache goes away (aversive stimulus removed) → you take aspirin again when you have a headache (behavior increased)

Positive punishment: child misbehaves → parent spanks (adds aversive stimulus) → child misbehaves less

Negative punishment: teenager breaks curfew → car keys taken away (pleasant stimulus removed) → teenager respects curfew

Schedules of Reinforcement

Continuous reinforcement: every response is reinforced. Fast acquisition, fastest extinction.

Fixed ratio (FR): reinforced after a set number of responses. High, steady response rate; brief pause after reinforcement. Example: piece-rate work (paid per item completed).

Variable ratio (VR): reinforced after an unpredictable number of responses. Highest, most persistent rate; most resistant to extinction. Example: slot machines, social media likes.
