Lecture Notes: Elephant Learning by Fagan

Introduction to the Study

  • Focus: Elephant learning, specifically trunk wash routine.
  • Location: Nepal, in response to the government's tuberculosis (TB) testing initiative for captive elephants.
  • Traditional training involved punishment with bamboo sticks (coas) by mahouts.
  • New initiative focuses on positive reinforcement.

Operant Conditioning and Positive Reinforcement

  • Positive Reinforcement: Rewarding a behavior to encourage it.
    • Example: Adding marks for student participation.
  • Secondary Positive Reinforcement (SPR): Using a secondary reinforcer (e.g., whistle) followed by a primary reinforcer (e.g., food).
  • SPR has been used successfully with various animal species.

Psychology Investigated

  • Operant Conditioning: Learning through positive/negative reinforcement or punishment.
  • Primary Reinforcer: Fulfills a basic biological need (e.g., food).
  • Secondary Reinforcer: Not naturally desired but linked to rewards (e.g., praise).

Aims of the Study

  • Train free-contact, traditionally trained elephants to voluntarily engage in a trunk wash.
  • Use SPR to facilitate voluntary TB testing in elephants.

Method and Design

  • Controlled and structured observation, not an experiment (no IV/DV).
  • Observation occurs in elephant stables in Nepal.
  • Sample: Five female elephants, four juveniles, one adult.

Procedure

  • Secondary Reinforcer: Short whistle blow.
  • Primary Reinforcer: Chopped bananas.
  • Training conducted in sessions, with mahouts present for safety.
  • Steps involve linking behaviors to rewards through capture, lure, and shaping techniques.
  • Behavioral Checklist: Trunk here, trunk up, bucket, blow, steady.

Results

  • Juvenile Elephants: Successfully learned the trunk wash.
  • Adult Elephant: Did not learn, possibly due to age, visual impairment, and distractions.
  • Session Data: Number of sessions varied per elephant, with juvenile elephants showing better learning outcomes.

Evaluation

  • Strengths:
    • Controlled procedures enhance reliability.
    • Positive reinforcement avoids punishment-based methods.
    • Application in training other animals.
  • Weaknesses:
    • Small sample size limits generalizability.
    • Subjectivity in scoring can affect validity.
  • Ethical Considerations: No harm to animals, desensitization used for syringe introduction.

Issues and Debates

  • Nature vs. Nurture: Study leans towards nurture due to learning through training.
  • Individual vs. Situational: Supports situational explanation but individual learning rates vary.
  • Application: Useful in maintaining elephant well-being and training other species.

Conclusion

  • Positive reinforcement (SPR) is effective in training elephants for trunk wash.
  • Study demonstrates the value of humane training methods over traditional punishment methods.
