Behaviourism

Question 1

Overview of Behaviourism

Answer 1

• Behaviourism: A psychological approach that focuses on observable behavior rather than internal mental states.
• Key Idea: All behavior is learned from the environment, and psychology should study behavior that can be observed and measured.
• Rejects: Introspection and the study of the mind, as these are considered subjective.

Question 2

Key Assumptions of Behaviourism

Answer 2

• Blank Slate: Individuals are born as a ‘tabula rasa’ (blank slate), and behavior is shaped by the environment.
• Learning through Association: Behavior is learned through associations, reinforcements, and punishments.
• Focus on the Scientific Method: Emphasizes objectivity and control in research, using lab experiments to study behavior.

Question 3

Classical Conditioning (Pavlov, 1927)

Answer 3

• Definition: A learning process where a natural stimulus is paired with a previously neutral stimulus, causing the neutral stimulus to elicit a response.
• Pavlov’s Experiment:
  o Unconditioned Stimulus (UCS): Food → Unconditioned Response (UCR): Salivation.
  o Neutral Stimulus (NS): Bell → No salivation.
  o After repeated pairings: Conditioned Stimulus (CS): Bell → Conditioned Response (CR): Salivation.
• Key Concepts:
  1. Stimulus Generalization: The conditioned response occurs for stimuli similar to the conditioned stimulus.
  2. Stimulus Discrimination: The conditioned response is specific to the conditioned stimulus.
  3. Extinction: The conditioned response diminishes when the conditioned stimulus is repeatedly presented without the unconditioned stimulus.

Question 4

Operant Conditioning (Skinner, 1938)

Answer 4

• Definition: Learning through consequences—behavior is shaped by reinforcements (rewards) and punishments.
• Skinner’s Experiment:
  o Skinner Box: A rat in a box presses a lever, receiving food (reinforcement) or avoiding a shock (negative reinforcement).
• Types of Reinforcement:
  1. Positive Reinforcement: Adding a pleasant stimulus to increase a behavior (e.g., praise for completing homework).
  2. Negative Reinforcement: Removing an unpleasant stimulus to increase a behavior (e.g., pressing a button to stop a loud noise).
  3. Punishment: Adding an unpleasant stimulus to decrease a behavior (e.g., scolding a child for misbehavior).

Question 5

Schedules of Reinforcement (Skinner)

Answer 5

• Continuous Reinforcement: Every desired response is reinforced, but extinction occurs quickly when reinforcement stops.
• Partial Reinforcement: Reinforcement is given intermittently, making behavior more resistant to extinction.
• Types of Partial Reinforcement:
  1. Fixed-Interval: Reinforcement is given after a fixed time (e.g., every 10 minutes).
  2. Variable-Interval: Reinforcement is given at unpredictable time intervals.
  3. Fixed-Ratio: Reinforcement is given after a fixed number of responses (e.g., after every 5th response).
  4. Variable-Ratio: Reinforcement is given after an unpredictable number of responses (e.g., slot machines), making it highly resistant to extinction.

Question 6

Evaluation of Classical and Operant Conditioning

Answer 6

• Strengths:
  1. Scientific Credibility: Emphasis on objectivity, control, and replication, making it reliable and scientific.
  2. Real-Life Application: Behaviorist principles have been applied in various settings, e.g., systematic desensitization for phobias, token economies in prisons and schools.
• Limitations:
  1. Environmental Determinism: Ignores free will and assumes behavior is solely determined by environmental factors.
  2. Reductionist: Reduces complex behavior to simple associations, ignoring cognitive factors and the role of biology.

Question 7

Social Learning Theory (Extension of Behaviourism)

Answer 7

• Developed by Albert Bandura as an extension of traditional behaviorism.
• Key Idea: Learning can also occur through observation and imitation, not just direct reinforcement.
• Vicarious Reinforcement: Learning through the observation of others being rewarded or punished.

Question 8

Key Research - Skinner and Pavlov

Answer 8

• Pavlov (1927): Showed that animals can be conditioned to associate a neutral stimulus with an unconditioned stimulus.
• Skinner (1938): Demonstrated how behavior can be shaped by consequences using operant conditioning. His research laid the foundation for behavior modification techniques.

Question 9

Real-Life Applications of Behaviourism

Answer 9

• Classical Conditioning: Treatment of phobias through Systematic Desensitization—gradually exposing a patient to a feared stimulus while practicing relaxation.
• Operant Conditioning: Used in education and behavior management (e.g., Token Economy Systems in prisons and schools to reinforce positive behavior).

Question 10

Behaviourism in Comparison to Other Approaches

Answer 10

• Behaviourism vs. Cognitive Approach: Behaviorism ignores mental processes, while the cognitive approach emphasizes the importance of internal thought processes.
• Behaviourism vs. Biological Approach: Behaviorism focuses on environmental learning, whereas the biological approach looks at genetic and physiological influences on behavior.

Question 11

Key Exam Points

Answer 11

• Define: Classical and operant conditioning, and the key concepts of reinforcement and punishment.
• Research: Be able to describe Pavlov’s and Skinner’s experiments in detail.
• Evaluation: Be prepared to evaluate the strengths and limitations of behaviourism, particularly its scientific credibility and real-world applications, as well as its deterministic and reductionist nature.
