Module 3 – Learning & Social-Cognitive (Behaviorist) Perspective: B. F. Skinner

Skinner: Historical Context and Biography

• Burrhus Frederic Skinner ( 1904{-}1990 ) grew up in Susquehanna, Pennsylvania in a warm, orderly home.

• Initially studied English at Hamilton College; after an unproductive attempt at becoming a novelist, shifted to psychology at Harvard.

• Academic Posts: University of Minnesota, Indiana University (as chair), and permanent return to Harvard.

• Key Publications: The Behavior of Organisms ( 1938 ), Walden Two ( 1948 ), Science and Human Behavior ( 1953 ), Beyond Freedom and Dignity ( 1971 ).

• Remained productive until his death, finishing his last paper one day before he passed away.

Learning and the Behaviorist Perspective

• Learning = “relatively permanent change in behavior produced by systematic interaction with environment.”

• Behaviorism restricts analysis to observable, measurable responses; internal mental states are excluded as scientific causes.

Scientific Analysis of Behavior

• Science seeks lawful relations among facts, not opinion.

• Complete behavioral analysis specifies:

  1. Antecedents (environmental events preceding behavior)

  2. Behavior (observable act)

  3. Consequences (events produced by the act)

  4. Genetic endowment & behavioral history are also noted.

• Research strategy: isolate components of complex acts, test them in controlled experiments, replicate independently.

• Contrast with Freud: Skinner rejects unconscious motives; only external contingencies count.

Skinner’s Conception of “Personality”

• No hidden inner self – only a repertoire of response patterns.

• Situational specificity: different environments evoke different learned patterns.

• Rejection of “mentalistic” states; these merely name, not explain, behavior.

• Buddhist parallel: impermanent, non-essential self; yet causes differ (Buddhism = karma/awareness; Skinner = reinforcement histories).

Explanatory Fictions (EF)

Skinner’s label for internal, unmeasurable “causes” that block real analysis.

Detailed illustrations:

• Milton Erickson ( 1939 ) – subjects obeyed post-hypnotic cue yet insisted they were free.

• Cross-species studies ( 1956 ) showed rats, pigeons, monkeys, and children learn identically → autonomy disproved.

• Butler quip: “A poet writes a poem as a hen lays an egg.”

• Later data (Lefcourt; Davison & Valins) demonstrate that belief in control can sustain motivation even if philosophically illusory.

Types of Conditioning & Reinforcement

Respondent (Classical) Conditioning

• Reflexive responses elicited by antecedent stimuli.

• Pavlov’s dogs: bell + food → bell elicits salivation.

• Modern uses: advertising pairs attractive images with products.

Operant Conditioning

• Voluntary actions shaped by their consequences.

• Skinner’s staged swimming example: successive candy rewards for wetting face → dipping head → blowing bubbles.

• Operant ≠ respondent: controlled by consequences, not antecedents.

Skinner Box Paradigm

• Lever press by hungry rat → food pellet (positive reinforcement) → response frequency rises.

• Withholding pellets → extinction.

• Demonstrates prediction & control via contingent reinforcement.

Key Empirical Findings

1. Conditioning without awareness (Ames room illusion, 1951 ): perception shaped culturally; non-Western observers did not see illusion.

2. Persistence despite awareness (Lindley & Moyer, 1961 ): subjects still lifted finger to tone formerly paired with shock even after told shock disabled.

3. Resistance impairs learning (Hilts, 1973 ): alcoholics counter-conditioned to vomit overcame aversion through peer support.

Nature of Reinforcers

• Positive: add pleasant stimulus (praise, candy).

• Negative: remove aversive stimulus (pain, noise).

• Primary: innate (food, water, air).

• Secondary: learned via association (money, grades, tokens).

  • Example: chimps exchange brass tokens for bananas.

Schedules of Reinforcement

• Ferster & Skinner ( 1957 ): partial schedules produce more persistent behavior than continuous reinforcement.

Behavioral Control & Cultural Engineering

• Goal: design environments so that desirable behavior is reinforced and sustained.

• Quote ( 1955 ): “Are we to be controlled by accident, by tyrants, or by ourselves…?”

• Extinction = removal of reinforcer → decline of behavior (rat stops lever-pressing when pellets stop).

Conditions That Foster or Impede Personal Growth

1. Growth = maximizing beneficial environmental control, minimizing harmful consequences.

2. Barrier: Ignorance of true contingencies (e.g., pigeon turning experiment; students invoked “hope” & “feel” explanations).

3. Functional Analysis: describe search for glasses via overt acts, not “states of mind.”

4. Ineffectiveness of Punishment:

   • Suppresses rather than teaches.

   • Produces fear, avoidance, aggression.

   • Example: marking only errors on exams teaches nothing.

5. Punishment Reinforces the Punisher: parent’s nagging stops when child cleans – nagging strengthened.

6. Preferred method: positive reinforcement of alternative behavior; punish only to prevent severe harm.

Successive Approximation (Shaping)

• Reinforce incremental steps toward remote, low-probability act.

• Pigeon trained to peck dot in < 3 minutes: turn → step → head thrust → peck.

• Language acquisition: babble → word fragments → full words, reinforced by parental attention.

Superstitious Behavior & Self-Control

• Superstition = accidental pairing of response with reward (player sleeps near bathroom → wins once → repeats ritual; 74\% of MLB players report such habits).

• Cultural difference: U.S. pros more superstitious than Japanese.

Techniques of Self-Management

1. Stimulus Avoidance – study in quiet library.

2. Self-Satiation – chain-smoke until disgust.

3. Aversive Stimulation – public commitment to weight loss.

4. Self-Reinforcement – buy new clothes after meeting study quota.

Applied Operant Programs

Token Economies

• Ayllon & Azrin ( 1968 ): psychotic female patients earned tokens for hygiene, work, dress → exchanged for candy, cigarettes, privileges. Outcomes: cleaner, sociable, responsible; effects faded without external contingencies post-discharge.

• Dallery et al. ( 2007 ): smokers uploaded CO readings; vouchers online – significant smoking reduction.

Behavior Modification in Industry & Schools

• Targets absenteeism, safety, productivity.

• Reinforcers: bonuses, promotions, reserved parking, public praise.

• Example: factory bonus for perfect attendance raised output & reduced sick days.

Punishment vs Reinforcement

• Punishment yields escape, aggression, learned helplessness; thrives in prisons & schools but escalates problems.

• Negative reinforcement (e.g., partner stops nagging when one refrains from smoking) can work but is less reliable and may entail harmful aversives.

Assessment Methods in Skinnerian Tradition

1. Functional Analysis – document frequency, antecedents, consequences (smoker logs cigarettes, contexts, rewards).

2. Direct Observation – multiple observers chart child behaviors; identify inadvertent parental reinforcement; treatment: ignore kicking, praise compliance.

3. Self-Report – interviews & questionnaires for covert acts (e.g., phobia ratings).

4. Physiological Measures – heart rate, EMG, EEG to uncover concealed reactions (rise during elevator questions despite verbal denial).

Evaluation of the Theory

Consolidated Strengths vs Limitations

Scientific Rigor: objective measurement, replicability ⟶ yet over-relies on non-human data, ignores cognition.
Real-World Application: wide success in clinics, schools, prisons ⟶ behaviors revert without ongoing reinforcement; generalization issues.
Predictability: lawful reinforcement schedules ⟶ underestimates agency, intrinsic motivation, uniqueness.
Legacy: foundation of CBT, educational technology, animal training ⟶ deemed determinist by humanistic & psychodynamic camps.
