Incomplete [🧠] Fagen et al. (elephant learning) Flashcards
Learning Approach | Elephant Learning
Define
Positive reinforcement
A favourable event or outcome given after a desired behaviour has been exhibited
What is
SPR training
Fagen et al. (elephant learning)
Secondary positive reinforcement is training in which a secondary reinforcer such as a sound marker is given, followed with administration of a primary positive reinforcer which is typically food
What is SPR training used for?
SPR training is used in order to form an association between behaviour and primary positive reinforcer
What is
free contact
Fagen et al. (elephant learning)
a management system where there is unlimited contact between handlers and elephants
What is
protected contact
Fagen et al. (elephant learning)
a management system where a barrier is maintained between the elephants and handlers, relying on positive reinforcement
it improves keeper safety
Benefits of secondary positive reinforcement for animal training
Fagen et al. (elephant learning)
For the animal
1. increases creativity, choice, control and problem solving
2. improved psychological wellbeing
For the handlers - safer conditions
What was the aim of the study?
Fagen et al. (elephant learning)
The aim of the study was to determine the effectiveness of secondary positive reinforcement on training free-contact, traditionally trained elephants to voluntarily perform a trunk wash for the purpose of tuberculosis testing
Sample of Fagen et al.
Fagen et al. (elephant learning)
- 5 female elephants
- 4 juveniles, 1 adult
- juveniles aged 5-7 years old
- adult in her 50s
- all elephants are free-contact
- none of the elephants had previously been exposed to SPR training
What can positive reinforcement training improve in husbandry and veterinary procedures?
- behavioural reliability
- captive management
- welfare

During the course of all sessions, what was the total training time for Elephant 2?
Fagen et al. (elephant learning)
257 minutes
During the course of all sessions, what was the total training time for Elephant 4?
Fagen et al. (elephant learning)
451 minutes
Define
operant conditioning
a method of learning that employs rewards and punishments for behavior, where an association is made between a behaviour and a consequence for that behavior
positive consequence → likely repetition of behaviour
negative consequence → unlikely repetition of behaviour
How does positive reinforcement affect a response/behaviour happening?
response or behaviour is strengthened by the addition of praise or a direct reward
Define
negative reinforcement
the removal of an unfavorable event or outcome after the display of a behaviour, where a response is strengthened by the removal of something considered unpleasant
Define
punishment
the presentation of an adverse event or outcome that causes a decrease in the behavior it follows. There are two kinds of punishment, positive and negative.
Define
punishment by application
positive punishment
punishment that presents an unfavorable event or outcome in order to weaken the response it follows.
Define
punishment by removal
negative punishment
punishment where a favourable event or outcome is removed after a behavior occurs, decreasing the behaviour
Significance of reinforcement schedules in the speed and strength of acquisition of behaviour
timing and frequency of reinforcement influences how new behaviours are learned and how old behaviours are modified
Distractions for the elephants
Fagen et al. (elephant learning)
- other animals in the neighbouring jungle
- the presence of large audiences of tourists sometimes approaching to take photographs during the training sessions
- the proximity of the afternoon sessions to their evening meal
Why did Elephant 5 fail to complete the training in the available time?
Fagen et al. (elephant learning)
- 2-month-old calf wandered into the training sessions on a regular basis, reached into the reward bucket, and interrupted the sessions. Mahouts’ efforts to minimize calf’s presence might have been even more distracting to Elephant 5
- for 1 week toward the end of training, Elephant 5 was noticeably impatient and unfocused, a period coinciding with the presence of a foot abscess
- Elephant 5 had some vision impairment and trunk weakness
- age might have also been a factor in her learning style (used to punishment by application)
- trainer’s were able to learn from failures and successes in one juvenile elephant and apply them to the other juveniles. These modifications were less applicable to Elephant 5 because she was the only adult
Individual differences in Elephant 1
Fagen et al. (elephant learning)
consistently showed impatience and declining performance with repetition; thus, her final trunk-wash test was preplanned to be only a 5-offer test (still requiring the 80% correct as passing criteria)
* she was the youngest; decline in performance with repetition can be attributed to age or simply personality
Application to everyday life
Fagen et al. (elephant learning)
- in less than a month, with one to two short training sessions a day, juvenile elephants can be taught to voluntarily participate in a trunk wash
- for elephants with severe trunk-handling phobia, they must undergo trunk desensitization to master certain skills and would benefit from a modified method
- training time varies with the trainer’s experience, strength of the reward, and stress level of the elephant.
