Interplay of Conditioning & Observational Learning – Vocabulary Review

Putting Classical and Instrumental Conditioning Together

• Real-world learning almost never involves only classical or only operant conditioning; they co-occur.

  • Example: Drinking alcohol is instrumentally reinforced (e.g., reduction of anxiety, social approval) and classically conditioned to pubs, friends, or a couch.

  • Result: Those environmental cues (S) gain motivational power and can themselves trigger drinking.

• Generic three-term contingency framework

  • Stimulus ($S$) → Response ($R$) → Outcome/Reinforcer ($O$)

  • Four possible associative links (see figure in text):

  1. $R \leftrightarrow O$

     • Core of instrumental/operant conditioning.

     • Governed by prediction-error principles (surprise matters).

     • Reinforcer devaluation effect: If $O$ loses value, $R$ declines.

  2. $S \leftrightarrow O$

     • Pavlovian/classical component.

     • Cue evokes preparatory physiological reactions (salivation, insulin release, body-temp change) and approach/avoidance.

     • Cue also primes the instrumental response.

  3. $S \leftrightarrow R$

     • Habit learning: after extensive practice, the cue can trigger the response automatically.

     • Performance becomes less sensitive to the current value of $O$.

  4. $S \rightarrow (R \rightarrow O)$

     • Occasion setting: the stimulus signals that the $R ext{-}O$ rule is “in force.”

     • Example: Canvas + paints → “painting will now be rewarded,” enabling the painter to start.

• Practical implications

  • Any everyday learned behavior can be parsed into these links.

  • Suggests multiple intervention points (e.g., alter cues, de-value outcomes, break habits, change occasion setters).

Observational Learning (Social Learning Theory)

• Definition: Learning a novel response by watching others (social models) rather than via direct reinforcement.

• Originator: Albert Bandura, 1977.

• Distinctive features

  • Reinforcement not required for initial acquisition.

  • Requires presence of social models—people of perceived higher status, expertise, or authority (parents, teachers, police, even skilled peers).

• Everyday illustrations

  • Child learns chess by watching experienced players.

  • Customer finds condiments after observing previous customers.

  • Child places napkin in lap after imitating parents.

Four-Part Process (Bandura)

1. Attention – Must notice the model’s behavior.

2. Retention – Must mentally encode and remember it.

3. Initiation (Motor Reproduction) – Must possess ability to perform the behavior.

4. Motivation – Must want or expect some benefit from performing it.

The Bobo Doll Experiments

• Original study (Bandura, Ross & Ross, 1961)

  • Procedure: Each child watched an adult interact with an inflatable clown (Bobo).

  • Aggressive model: punching, kicking, striking with a mallet.

  • Non-aggressive model: played with other toys, ignored Bobo.

  • After observation, child played alone with Bobo.

  • Results: Children exposed to aggression reproduced significantly more aggressive acts (hitting, kicking) toward Bobo than controls.

  • Interpretation: Children used observed adult behavior as a guide—aggression toward Bobo is “acceptable.”

• Follow-up study (Bandura, Ross & Ross, 1963)

  • Manipulated consequences for the model (reward vs punishment).

  • Vicarious reinforcement: Observers reduced aggressive acts when they saw the model punished, even though they were not punished themselves.

Integrated View of Learning Mechanisms

• Three major pathways shape behavior:

  1. Operant conditioning – We repeat actions that have been reinforced (e.g., wearing outfits that earned compliments).

  2. Classical conditioning – Neutral cues become motivational (e.g., restaurant jingle with happy music → positive feelings about the restaurant).

  3. Observational learning – We adopt behaviors we have seen rewarded or not punished in others (e.g., submitting assignments on time after witnessing penalties for late work).

• In practice, these mechanisms often interact.

  • Example: Observing a friend receive social approval for volunteering (observational) increases your likelihood of volunteering (operant), and the volunteer environment (cue) starts to feel good (classical).

Key Terms & Concepts

• $S$: Stimulus or set of stimuli (context, cues)

• $R$: Operant response (behavior)

• $O$: Outcome/reinforcer/punisher

• Prediction error: Difference between expected and obtained outcome; drives learning.

• Reinforcer devaluation: Reduction in responding when $O$ loses desirability.

• Habit: Direct $S \rightarrow R$ control; outcome becomes secondary.

• Occasion setter: Stimulus that modulates whether a particular $R \rightarrow O$ link applies.

• Vicarious reinforcement: Change in observer’s behavior after seeing model’s outcomes.

• Social model: Person whose behavior is observed for cues on how to behave.
