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.
