Classical Conditioning in Learning Theories

Introduction to Learning Theories

• Fields of Psychology studied:
  • Social Psychology: Behaviors learned through cultural and societal influences
  • Cognitive Psychology: Behaviors shaped by memory and cognitive processes (schemas)
  • Biological Psychology: Behaviors influenced by biological factors (brain structures, neurotransmitters, genetics, hormones)

Behaviorism

• Behaviorist Perspective:
  • Asserts that behaviors are learned primarily through social and family environments
  • Emphasizes scientific measurement of observable behaviors

Fundamental Concepts in Behaviorism

• Tabula Rasa:

  • Latin for “Blank Slate”
  • The belief that individuals are born without built-in mental content; all behavior is learned

• Key Assumptions of Learning Theories:

  • All behavior is learned
  • Only measurable and observable behaviors are considered
  • Mental processes are generally disregarded

Features of Behavioral Psychology

• Learning is achieved through:
  • Association: Pairing stimuli to produce responses
  • Rewards and Punishments: Encouragement of certain behaviors by positive outcomes or discouragement by negative outcomes
  • Aversion Therapy: Using unpleasant stimuli to deter unwanted behaviors

Classical Conditioning

• Stimulus-Response Relationship:
  • Unconditioned Response (UCR): Natural reaction to an unconditioned stimulus (UCS)
  • Examples: Startling at loud noises, laughing when tickled
  • Initially, a Neutral Stimulus (NS) does not provoke a response

Process of Conditioning

• Conditioning Defined:
  • The process of associating a Neutral Stimulus (NS) with an Unconditioned Stimulus (UCS) over time to elicit a Conditioned Response (CR)

Phases of Conditioning

• Before Conditioning:
  • NS → No Response
• During Conditioning:
  • NS + UCS → UCR
• After Conditioning:
  • CS (formerly NS) → CR

Conditioned Responses

• After conditioning, the NS becomes a Conditioned Stimulus (CS), producing the same effect as the UCS.
  • The learned effect is known as a Conditioned Response (CR)

Extinction and Recovery

• Extinction:
  • Gradual loss of association between CS and UCS, reverting to a NS
• Spontaneous Recovery:
  • The return of a CR after a period of extinction
• Stimulus Generalization:
  • Similar stimuli can evoke a CR

Significant Research in Classical Conditioning

• Pavlov (1927): Classic conditioning with dogs
• Watson & Rayner (1920): Prominent classical conditioning study

Ethical Concerns in Classical Conditioning Research

• Example: David H. Barlow (1966) attempted aversion therapy to change sexual orientation by pairing sick-inducing stimuli with attractive images.
• Treatment was ineffective and reported as traumatizing by participants

Limitations of Conditioning in Understanding Sexuality

• Some behaviors, such as sexual orientation, may be innate rather than learned.
  • Emotional factors like love must be considered alongside conditioning

Applications of Aversion Therapy

• Used for addictions, such as alcohol:
  • Antabuse creates nausea when alcohol is consumed; changing alcohol's UCS to a CS that induces nausea
  • Parental techniques also utilized for behavior correction through negative associations

Key Terminology

• Conditioning: The process of learning associations
• UCS: Unconditioned Stimulus
• UCR: Unconditioned Response
• CS: Conditioned Stimulus
• CR: Conditioned Response
• Extinction: Loss of learned behavior
• Spontaneous Recovery: Return of conditioned response after extinction

Credibility of Classical Conditioning

• Supported by substantial research and contemporary studies, including neuroimaging on reward centers in the brain
• The observable nature of conditioning lends scientific credibility

Objections to Classical Conditioning

• Generalizing animal studies to humans involves complexities
• Other learning theories (e.g., Operant Conditioning, Social Learning Theory) also explain behavior
• The model emphasizes nurture, disregarding innate predispositions
• Lacks consideration for cognition and the role of unconscious processes

Key Differences from Other Learning Theories

• Similarities with Operant Conditioning: Both use lab studies, generalizations to humans, and provide treatment frameworks
• Distinct in that Classical Conditioning focuses on involuntary responses whereas Operant Conditioning emphasizes voluntary behavior due to consequences
• Social Learning Theory (SLT) incorporates cognition, explaining behavior through observation and imitation

Applications of Classical Conditioning

• Used effectively in therapy for irrational problems (phobias, addictions)
• Aversion Therapy: Links unwanted behaviors to negative stimuli
• Systematic Desensitization: Gradual exposure to feared stimuli in a relaxed state leads to extinction of fear response
• Each therapy emphasizes patient willingness for successful outcomes.
