fagen et al (elephant learning Flashcards
psychology being investigated
operant conditioning and positive reinforcement
primary and secondary reinforcement
shaping and chaining
define operant conditioning
operant conditioning refers to the type of learning in an organism where the consequences after an action determine if it is more or less likely to perform it again. can be manipulated through reinforcement and punishment
primary and secondary reinforcement in the study
correct trunk position rewarded with chopped banana primary
whistle while banana given secondary
shaping and chaining
rewarding only behaviour that is close to or is target behaviour
chaining:combining multiple singular actions into a sequence for the trunk wash
aim of fagen et al
to determine the feasibility of SPR training on free contact, traditional elephants to participate in trunk wash voluntarily
sample
opportunity
5 female
4 juvenile 1 adult in 50s
natural environment
selection of individuals based on docility, mahouts, lack of pregnancy or current calf
no changes made to standard husbandry conditions, no changes made to grazing, chaining and water
research methodology
structured observation with longitudinal design
timings of training
7:30 am to 10am and 4pm to 7pm
not all elephants trained every session, but no elephant went without 2 days of training
could elephants refuse to participate
yes their chain was 6 to 8 ft allowed sufficient room to turn away or walk away
what was the required behaviour
elephant must put the ventral aspect of the tip of her trunk gently on the trainers hand, allow the trainer to instill saline with a syringe, lift trunk up so fluid runs to base, hold fluid, and blow fluid out into the bucket
training steps
- teach elephants to bridge primary and secondary reinforcers, through repetitive pairing
- capture: naturally occuring behaviours are waited for by the trainer then captured through rewarding
- lure: reward placed strategically to require elephant to position body to access it.
- shaping: relies on natural variation in quality of behaviours, only best rewarded
trained behaviors
- trunk here
- trunk up
- bucket
- blow
- steady
- syringe
- blow into bucket
- trunk down
- trunk out
- targeting
trunk here
elephant places end of her trunk gently on trainers hand to allow instillation of saline water
trained using lure, rewarded only when ventral aspect of tip was placed
trunk up
lift trunk to allow saline to run down lure used and shaped to increase height
