Chapter 4: Learning Approach

Learning Intentions

  • In this chapter, you will learn how to:

    • Describe and apply the concepts and terminology of the learning approach and its main assumptions.

    • Explain and apply the psychology being investigated in the learning approach.

    • Describe, evaluate and apply the three core studies from the learning approach.

    • Apply relevant research methods to the learning approach.

    • Consider issues and debates that are relevant to the learning approach.

Introduction

  • The aim of this chapter is to introduce you to the learning approach to psychology and to explore three studies that illustrate this approach:

    • Bandura et al. (aggression): Based on social learning theory; examines the effect of adult behavior on children, particularly aggression.

    • Fagen et al. (elephant learning): Explores positive reinforcement training in elephants to improve welfare.

    • Saavedra and Silverman (button phobia): A case study of a boy with a phobia of buttons, utilizing classical conditioning to reduce this fear.

Key Concepts in the Learning Approach
  • This approach is concerned with how humans and animals change and acquire behavior through different mechanisms, including:

    • Learning from others (social learning)

    • Learning by association (classical conditioning)

    • Learning from rewards and punishments (operant conditioning)

  • Learning is defined as new, permanent changes in behavior following experience.

  • The comparison of learning mechanisms in humans and animals highlights both similarities and differences in capabilities and learning processes.

Main Assumptions in Context

  • The following are the main assumptions of the learning approach:

    • Blank Slate: Each individual is born without mental content; knowledge is acquired from the environment.

    • Key Term: Blank slate: The idea that all individuals are born without any mental content, necessitating experience to form knowledge.

    • Learning Processes: Learning involves social learning, operant conditioning, and classical conditioning, where experiences shape behavior through stimulus-response interactions.

  • Definition by Kimble (1961): "Learning is defined as a relatively permanent change in behavioral potential which accompanies experience."

    • The definition has three parts:

    • Acquisition of new responses (relatively permanent change).

    • Learning can occur without demonstrated behavior (behavioral potential).

    • The environment provides opportunities and influences learning.

  • Consideration of repeated stimulus exposure, rewards, and role models as pivotal elements of the environment affecting behavior.

Core Study 1: Bandura et al. (Aggression)

  • Reference: Bandura, A., Ross, D., & Ross, S. A. (1961). "Transmission of aggression through imitation of aggressive models". Journal of abnormal and social psychology, 63(3), 575–582.

Psychology Being Investigated
  • The study focuses on children imitating adults, highlighting social settings as significant in behavior imitation. Important factors include:

    • Attention and retention by the observer (child) are critical to learning from models.

    • Expectation: Observing aggressive models leads to increased aggressive behavior and vice versa for non-aggressive models.

Keywords
  • Model: A person who inspires or encourages others to imitate behavior.

  • Social learning: Learning behavior by observing and later imitating a role model.

  • Aggression: Behavior aimed at harming others either physically or psychologically.

Aim and Hypotheses
  • The aim was to investigate whether children would learn aggression through observation and whether the sex of the model mattered.

  • Four hypotheses were proposed:

    1. Children exposed to an aggressive model would exhibit more aggression than those exposed to a non-aggressive or control model.

    2. Observed non-aggressive behavior would lead to less aggression compared to controls.

    3. Children will imitate same-sex models more frequently.

    4. Boys will copy aggressive behavior more than girls.

Issues and Debates
  • Nature vs. Nurture: The debate underscores the role of environment in shaping behavior, particularly how adults act as models and enforce rewards/punishments.

Methodology
  • Research Method: Laboratory experiment with independent measures design.

  • Sample: Seventy-two children aged 3-6 (36 boys and 36 girls) from Stanford University nursery school.

  • Procedure: Children were observed for aggression levels and subsequently assigned to groups based on aggression matching.

  • Dependent Variable: Observations of children’s behavior post-exposure were noted through controlled observation.

Results
  • Children exposed to aggressive models were significantly more aggressive compared to those in non-aggressive or control groups.

  • Gender differences in aggression levels were noted, with boys showing higher aggression levels than girls when exposed to male models.

Ethical Considerations
  • Ethical concerns arose from potential psychological harm and aggressive behavior learned by children. The study's potential impact on child psychology was highlighted.

Conclusion
  • Bandura et al.’s study demonstrates that observation and imitation play critical roles in learning behaviors, supported by the findings that aggression could be learned without reinforcement.

Core Study 2: Fagen et al. (Elephant Learning)

  • Reference: Fagen, A., Acharya, N., & Kaufman, G. E. (2014). "Positive reinforcement training for a trunk wash in Nepal's working elephants". Journal of applied animal welfare science, 17(2), 83-97.

Psychology Being Investigated
  • The study embodies operant conditioning, demonstrating learning based on the outcomes of behavior through reinforcement.

  • Positive reinforcement is emphasized, showcasing improvements in animal welfare.

Research Design
  • Controlled observation of elephants using behavioral checklists to gauge responses to training.

  • Positive reinforcement was coupled with secondary reinforcers (sounds) to train elephants for health management.

Results
  • Majority of juvenile elephants successfully learned the trunk wash behavior, while an adult elephant exhibited challenges, demonstrating individual variances in learning capacity.

Conclusion
  • The study confirmed that positive reinforcement can effectively train captive elephants and improve their welfare.

Core Study 3: Saavedra and Silverman (Button Phobia)

  • Reference: Saavedra, L. M., & Silverman, W. K. (2002). "Case study: disgust and a specific phobia of buttons". Journal of the American Academy of Child and Adolescent Psychiatry, 41(11), 1376-1379.

Psychology Being Investigated
  • This study integrates classical conditioning principles to understand the development of phobias and the role of disgust as a potential target for treatment.

Methodology
  • The study's aim was to evaluate the efficacy of positive reinforcement and imagery exposure in treating button phobia in the subject, a 9-year-old boy.

  • The clinical case study design allowed deep exploration of personal experiences and phobia treatment.

Results
  • Imagery exposure therapy proved effective in reducing the patient's disgust and fear, contrasting with the less effective outcomes of positive reinforcement.

Conclusion
  • The study indicates the significance of addressing both disgust and fear in phobia treatment and validates imagery techniques alongside traditional behavioral therapies.

Issues, Debates, and Applications of Learning Approach

  • Applications in everyday life can be seen in parental controls and media limitations to mitigate aggressive behaviors in children observed through Bandura et al.

  • Individual and situational factors matter within the learning environment, highlighting both innate and environmental influences.

  • Ethical considerations arise, especially with children and animals in research contexts, emphasizing the need for protective measures and informed consent.

  • Learning approaches underlie therapy methods utilizing conditioning, furthering practical applications in clinical psychology.
