Behavioural Perspective

Introduction

The behavioral perspective (also called behaviorism or learning theory) views abnormal behaviors as learned responses to environmental stimuli. This approach emerged as a reaction to psychoanalysis and focuses exclusively on observable, measurable behavior rather than internal mental states. The fundamental premise is that all behavior—normal and abnormal—is learned through interactions with the environment and can therefore be unlearned or changed through the same principles.

Core Assumptions

  1. Focus on Observable Behavior: Only measurable behavior is studied, not thoughts or feelings
  2. Environment Determines Behavior: External factors shape actions
  3. Learning is Central: All behavior is learned through conditioning
  4. Universal Principles: Same laws apply to all organisms and behaviors
  5. Scientific Approach: Objective, experimental methods
  6. Present-Focused: Current environmental factors maintain problems
  7. Optimistic View: If learned, can be unlearned or relearned

Types of Learning

1. Classical Conditioning (Respondent Conditioning)

Discovered by: Ivan Pavlov

Basic Process: Learning through association between two stimuli

Key Terms:

  • Unconditioned Stimulus (UCS): Naturally triggers response (food)
  • Unconditioned Response (UCR): Natural, automatic response (salivation to food)
  • Conditioned Stimulus (CS): Previously neutral stimulus paired with UCS (bell)
  • Conditioned Response (CR): Learned response to CS (salivation to bell)

Process:

  1. Before conditioning: UCS → UCR (food → salivation)
  2. During conditioning: CS + UCS → UCR (bell + food → salivation)
  3. After conditioning: CS → CR (bell → salivation)

Key Principles:

Acquisition:

  • Learning occurs through repeated pairings
  • CS must precede UCS closely in time
  • Strength increases with repetitions

Extinction:

  • CR weakens when CS presented without UCS
  • Response eventually disappears
  • Not permanent erasure—spontaneous recovery possible

Spontaneous Recovery:

  • Extinguished response reappears after rest period
  • Usually weaker than original
  • Shows learning not completely erased

Stimulus Generalization:

  • CR occurs to stimuli similar to original CS
  • Example: Fear of one dog generalizes to all dogs
  • Broader the generalization, weaker the response

Stimulus Discrimination:

  • Learning to distinguish between similar stimuli
  • Respond to CS but not to similar stimuli
  • Requires differential reinforcement

Higher-Order Conditioning:

  • CS from first conditioning becomes UCS for new learning
  • Example: Bell → food, then light → bell
  • Each level weaker than previous

Application to Mental Disorders:

Phobias:

  • Fear learned through association
  • Neutral stimulus paired with frightening experience
  • Example: Dog bite (UCS) → fear (UCR); Now dog (CS) → fear (CR)
  • Generalization explains spreading fears

Anxiety Disorders:

  • Environmental cues associated with danger
  • Physical sensations become conditioned stimuli
  • Panic attacks can be conditioned responses

PTSD:

  • Trauma (UCS) → fear/distress (UCR)
  • Trauma-related cues (CS) → anxiety (CR)
  • Generalization to safe situations

Substance Use:

  • Drug use paired with environmental cues
  • Cues trigger cravings (CR)
  • Places, people, times associated with use

2. Operant Conditioning (Instrumental Learning)

Developed by: B.F. Skinner (built on Thorndike’s work)

Basic Process: Learning through consequences of behavior

Fundamental Principle: Behavior followed by reinforcement increases; behavior followed by punishment decreases

Key Concepts:

Reinforcement: Increases probability of behavior

Positive Reinforcement:

  • Adding pleasant stimulus after behavior
  • Strengthens behavior by rewarding it
  • Examples:
    • Praise for good behavior
    • Money for work
    • Attention for acting out (unintentionally reinforcing)
    • Relief/pleasure from substance use

Negative Reinforcement:

  • Removing unpleasant stimulus after behavior
  • Strengthens behavior by removing something aversive
  • Often confused with punishment (but increases behavior)
  • Examples:
    • Taking pain medication removes pain
    • Compulsions reduce obsessional anxiety
    • Avoidance removes anxiety
    • Substance use reduces withdrawal symptoms

Punishment: Decreases probability of behavior

Positive Punishment:

  • Adding unpleasant stimulus after behavior
  • Weakens behavior by presenting something aversive
  • Examples:
    • Spanking
    • Electric shock
    • Criticism, reprimands

Negative Punishment:

  • Removing pleasant stimulus after behavior
  • Weakens behavior by taking away something desired
  • Examples:
    • Time out
    • Taking away privileges
    • Fines

Schedules of Reinforcement:

Continuous Reinforcement:

  • Every response reinforced
  • Rapid learning
  • Quick extinction

Intermittent (Partial) Reinforcement:

  • Only some responses reinforced
  • Slower learning
  • More resistant to extinction
  • Types:

  1. Fixed Ratio (FR): Reinforcement after specific number of responses

    • Example: Pay per piece produced
    • Produces high rate of responding

  2. Variable Ratio (VR): Reinforcement after varying number of responses

    • Example: Gambling, slot machines
    • Highest rate of responding
    • Most resistant to extinction

  3. Fixed Interval (FI): Reinforcement after specific time period

    • Example: Weekly paycheck
    • Responding increases near reinforcement time

  4. Variable Interval (VI): Reinforcement after varying time periods

    • Example: Pop quizzes
    • Steady, moderate responding

Shaping:

  • Reinforcing successive approximations toward target behavior
  • Breaking complex behavior into steps
  • Used for teaching new behaviors

Chaining:

  • Linking series of behaviors together
  • Each behavior cues next and is reinforced by opportunity for next
  • Teaches complex sequences

Extinction in Operant Conditioning:

  • Stopping reinforcement of previously reinforced behavior
  • Behavior decreases and eventually stops
  • Extinction Burst: Temporary increase before decrease

Application to Mental Disorders:

Depression:

  • Low rate of positive reinforcement
  • Withdrawal reduces opportunities for reinforcement
  • Learned helplessness (Seligman)
  • Lack of response-contingent positive outcomes

Anxiety Disorders:

  • Avoidance Maintained by Negative Reinforcement:
    • Avoiding feared situation reduces anxiety (reinforcing)
    • Prevents extinction of fear
    • Two-factor theory (Mowrer): Classical conditioning creates fear, operant conditioning maintains avoidance

OCD:

  • Compulsions negatively reinforced by anxiety reduction
  • Temporary relief strengthens rituals
  • Prevents extinction of obsessional fears

Attention-Seeking Behaviors:

  • Behavior maintained by attention (positive reinforcement)
  • Even negative attention reinforces
  • Ignoring (extinction) can reduce behavior

Substance Abuse:

  • Positive reinforcement (pleasure, high)
  • Negative reinforcement (escape from problems, withdrawal relief)
  • Variable ratio schedule (unpredictable effects) creates strong habit

Aggression:

  • May be reinforced by getting desired outcome
  • Removes frustrating situation
  • Gains attention or status

3. Observational Learning (Social Learning)

Developed by: Albert Bandura

Basic Process: Learning by watching others (models)

Does Not Require Direct Experience: Can learn without personal trial and error

Key Components (Bandura’s Four Processes):

  1. Attention: Must notice the behavior

    • Influenced by model’s characteristics (attractive, powerful, similar)
    • Salience and relevance of behavior

  2. Retention: Must remember what observed

    • Mental representations
    • Cognitive coding and rehearsal

  3. Reproduction: Must be able to perform behavior

    • Physical and cognitive capabilities
    • Practice and feedback

  4. Motivation: Must want to perform behavior

    • Vicarious reinforcement (seeing model rewarded)
    • Expected outcomes
    • Self-efficacy beliefs

Vicarious Learning:

  • Learning from observing consequences to others
  • Vicarious Reinforcement: Seeing model rewarded increases imitation
  • Vicarious Punishment: Seeing model punished decreases imitation

Bobo Doll Experiment (1961):

  • Children observed adult hitting doll
  • Later, children imitated aggressive behavior
  • Demonstrated observational learning of aggression
  • Showed children learn behaviors not directly reinforced

Application to Mental Disorders:

Phobias:

  • Can be acquired by watching others’ fearful reactions
  • Informational learning about dangers
  • Parents’ fears modeled to children

Aggression:

  • Learned through observation of aggressive models
  • Media violence concerns
  • Domestic violence exposure

Social Anxiety:

  • Learning from socially anxious parents
  • Observing social rejection or embarrassment
  • Modeling avoidance behaviors

Eating Disorders:

  • Modeling thin-ideal behaviors
  • Peer influence on dieting
  • Media images of ideal body types

Substance Use:

  • Peer modeling
  • Media portrayals
  • Family substance use patterns

Adaptive Skills:

  • Positive: Coping strategies learned from others
  • Social skills acquired through observation
  • Resilience modeled by others

Behavioral Explanation of Mental Disorders

General Principles

  1. Learned Maladaptive Behaviors: Problems are learned responses to environment
  2. Classical Conditioning: Creates emotional associations (fears, cravings)
  3. Operant Conditioning: Maintains behaviors through consequences
  4. Observational Learning: Acquired from models
  5. Environmental Factors: Current environment maintains problems
  6. No Underlying Disease: Behavior itself is the problem

Two-Factor Theory (Mowrer)

Explains Anxiety Disorders, especially Phobias:

Factor 1 - Classical Conditioning:

  • Fear acquired through association
  • Neutral stimulus paired with trauma/fear

Factor 2 - Operant Conditioning:

  • Avoidance maintained by negative reinforcement
  • Avoiding feared stimulus reduces anxiety
  • Prevents extinction of fear
  • Maintains and strengthens phobia

Example - Dog Phobia:

  1. Dog bite (UCS) → fear (UCR) [Classical]
  2. Dog (CS) → fear (CR) [Classical]
  3. Avoiding dogs → anxiety relief [Operant - negative reinforcement]
  4. Avoidance prevents learning dogs are safe [Prevents extinction]

Behavioral Treatments

Goal

Directly change problem behaviors through learning principles

Techniques Based on Classical Conditioning

1. Systematic Desensitization (Joseph Wolpe):

Process:

  1. Relaxation Training: Learn deep muscle relaxation (incompatible with anxiety)
  2. Fear Hierarchy: Create list of feared situations (least to most anxiety-provoking)
  3. Gradual Exposure: Pair relaxation with imagined exposure, working up hierarchy
  4. Counterconditioning: Replace fear response with relaxation

Applications: Phobias, anxiety disorders

2. Flooding (Implosion Therapy):

Process:

  • Immediate, intense exposure to most feared stimulus
  • Remain in situation until anxiety naturally decreases
  • No gradual build-up
  • Extinction through prolonged exposure without negative consequences

In vivo: Real-life exposure Imaginal: Imagined exposure

Applications: Phobias, PTSD, OCD

3. Exposure Therapy:

Process:

  • Confronting feared situations repeatedly
  • Remain in situation until anxiety decreases (habituation)
  • Response prevention (don’t escape or use safety behaviors)
  • Extinction of conditioned fear response

Types:

  • In vivo exposure: Real-life situations
  • Imaginal exposure: Imagining scenarios
  • Virtual reality exposure: Computer-generated environments
  • Interoceptive exposure: Exposure to physical sensations

Applications: All anxiety disorders, PTSD, OCD

4. Aversion Therapy:

Process:

  • Pair unwanted behavior with unpleasant stimulus
  • Create negative association
  • Classical conditioning to reduce behavior

Examples:

  • Alcoholism: Alcohol paired with nausea-inducing drug (Antabuse)
  • Smoking: Rapid smoking until nauseous
  • Nail-biting: Bitter-tasting nail polish

Ethical Concerns: Controversial, rarely used today

    • Behaviorists: Little evidence for symptom substitution

  5. Ethics of Behavior Control:

    • Who decides what behaviors to change?
    • Manipulation concerns
    • Dignity and autonomy issues

  6. Individual Differences:

Conclusion

The behavioral perspective revolutionized psychology by establishing it as a rigorous science based on observable, measurable phenomena. By focusing on learning principles—classical conditioning, operant conditioning, and observational learning—behaviorism provides clear explanations for how many problem behaviors develop and are maintained.

Behavioral treatments, grounded in learning theory, have demonstrated effectiveness for numerous mental disorders, particularly anxiety disorders, phobias, OCD, and PTSD. The emphasis on objective assessment, specific techniques, and measurable outcomes has made behavior therapy a cornerstone of evidence-based practice.

While criticized for initially ignoring cognitive processes and internal experiences, modern behavioral approaches have evolved to integrate cognitive elements, resulting in the highly effective cognitive-behavioral therapy (CBT). The behavioral perspective’s enduring contribution is its demonstration that behavior can be systematically studied and changed through application of scientific principles.
