Approach and research focus
Learning approach. The study investigates whether secondary positive reinforcement can teach working elephants to participate voluntarily in a trunk-wash procedure used for health monitoring.
Background: Reliable trunk-wash samples can help monitor elephant health, but traditional handling can make the procedure difficult. The researchers explored a stepwise training alternative that marks desired responses and follows them with food rewards.
Aim and procedure
Five female Asian elephants at one Nepalese stable took part: four juveniles aged 5–7 and one adult estimated to be in her 50s. Staff selected animals based on docility, health/reproductive status and handler willingness. None had previous secondary-positive-reinforcement training. Trainers used markers and food to shape separate actions—such as presenting the trunk, holding a position and blowing into a collection container—then chained them into the full trunk wash. Behavioural checklists assessed task performance across repeated sessions.
Results and conclusion
All four juveniles learned the full trunk wash within the study period, after 25–35 training sessions each. The adult did not learn all required components and did not pass the full procedure. The authors concluded that this approach was feasible for the juvenile elephants in this setting, not that it would work for every elephant or handler.
Secondary positive reinforcement and shaping can support voluntary completion of a complex chained behaviour for some working elephants. The study demonstrates feasibility in a small selected group; it does not compare long-term welfare or medical outcomes against every traditional method.
Evaluate the evidence
A behaviour checklist and sequential task tests make training progress visible; the full trunk wash is a meaningful applied behaviour.
Five selected elephants at one stable are a very small, non-random sample; the four juvenile successes and one adult non-completion cannot establish age as the cause.
A trainer judged whether performance quality was sufficient for a full wash, leaving room for subjective assessment; video review or independent scoring would strengthen reliability.
Animals were in a captive working context with restricted movement outside grazing/training. Turning away allowed some refusal, but this does not make the wider management context unrestricted.
Ethics and issues/debates
The article describes animal-care oversight and voluntary training steps; it also reports that elephants were leg-chained in stalls outside grazing periods. Discuss welfare as a whole rather than equating a food reward with unrestricted choice.
Welfare review should consider handler safety, stress, the animals’ ability to stop, and whether the medical procedure benefits the animals.
The learning approach explains acquisition through consequences, shaping and chaining observable actions.
The procedure has an everyday-health application, but training feasibility is not evidence of improved long-term welfare on its own.
The sample shows individual differences: four juveniles completed the chain and the adult did not; do not treat one failure as proof that adults cannot learn.

Worked example
A keeper says, ‘Positive reinforcement worked for elephants.’ State what the study supports and what remains uncertain.
Show the worked solution
- Four of five selected females completed a trunk wash; the adult did not.
- The study supports feasibility in this stable and training arrangement.
- The sample was small, selected and contained only one adult, so it cannot establish universal effectiveness or age effects.
Answer The study showed that the training method was feasible for four juvenile elephants at one stable. It does not establish that it works for all elephants or that age caused the adult’s non-completion.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Four juveniles completed the chain after 25–35 sessions, while one adult did not. Write a careful summary.
Give me a hint
Separate feasibility from a general claim about age or species.
Compare my reasoning
- The method enabled four selected juvenile elephants to complete the procedure.
- One adult did not learn all components within the study period.
- With one adult and five animals total, the result does not show why that individual did not complete it.
The training was feasible for four juveniles at this stable, while the adult did not complete it; the sample cannot establish an age effect.
Look for these in your work
- Both outcomes reported
- Conclusion bounded to setting
- No causal age claim
Explain how shaping and chaining can teach the trunk wash, then evaluate one measurement limit.
Give me a hint
Describe component behaviours and the judgement used to score the full procedure.
Compare my reasoning
- Reinforce separate actions such as trunk presentation, holding and blowing.
- Link learned components into the ordered trunk-wash chain.
- The trainer judged whether performance quality was adequate, so independent video scoring could improve reliability.
Successive reinforcement can build and chain the steps, but the trainer’s subjective pass judgement is a measurement limitation.
Look for these in your work
- Shaping described
- Chaining described
- Scoring limit explained
Plan a welfare-focused test of a marker-and-reward routine for a new veterinary-care behaviour.
Give me a hint
Define a voluntary action, a consistent criterion and an animal-welfare safeguard.
Compare my reasoning
- Choose one harmless preparatory behaviour and break it into small steps that can be marked consistently.
- Use a clear performance checklist and record attempts and refusals without forcing completion.
- Use veterinary and animal-care oversight, allow the animal to disengage, and evaluate success and welfare indicators separately.
A small-step, marked reinforcement plan can be tested with a defined checklist and a genuine stop option, under welfare oversight.
Look for these in your work
- Target behaviour observable
- Progress criterion set
- Refusal and welfare respected
Common mistakes
- Saying all five elephants completed the trunk wash
- Treating a reward marker as the primary reinforcer rather than a learned secondary reinforcer
- Calling a five-animal selected sample representative
- Ignoring captivity and chaining when evaluating welfare
