Q

define operant conditioning

A

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

Q

shaping and chaining

A

rewarding only behaviour that is close to or is target behaviour
chaining:combining multiple singular actions into a sequence for the trunk wash

Q

sample

A

opportunity
5 female
4 juvenile 1 adult in 50s
natural environment
selection of individuals based on docility, mahouts, lack of pregnancy or current calf

Q

timings of training

A

7:30 am to 10am and 4pm to 7pm

not all elephants trained every session, but no elephant went without 2 days of training

Q

could elephants refuse to participate

A

yes their chain was 6 to 8 ft allowed sufficient room to turn away or walk away

Q

what was the required behaviour

A

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

Q

training steps

A
  1. teach elephants to bridge primary and secondary reinforcers, through repetitive pairing
  2. capture: naturally occuring behaviours are waited for by the trainer then captured through rewarding
  3. lure: reward placed strategically to require elephant to position body to access it.
  4. shaping: relies on natural variation in quality of behaviours, only best rewarded

Q

trunk here

A

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

16
Q

bucket

A

elephant places distal end of trunk in bucket in preparation to blow

17
Q

blow

A

strong exhale to blow solution, captured and shaped behaviour

18
Q

steady

A

holds position previously instructed, no hand cue, just maintenance of action hand cue

19
Q

syringe

A

elephant holds trunk still as trainer gets syringe closer and closer to trunk, until syringe is places inside distal end of trunk and 60ml instilled

20
Q

trunk down

A

relaxed position hanging downwards

21
Q

trunk out

A

trunk stretched out parallel to floor

22
Q

targeting

A

elephant moves to place the center of its forehead to make contact with end of targeting stick

23
Q

what kind of cues were individual tasks paired with

A

monosyllabic verbal cues, that very a distinct sound made to mean nothing in english or nepali

24
Q

which 3 behaviours were abandoned

A

trunk down, targeting and trunk out

25
how was sample fluid introduced
through desensitisation and counterconditioning, reward was used to make make potentially negative experience less aversive started with 0.9% saline and given water earlier to avoid drinking solution
26
data collection parameters
session times number of offers performance tests
27
session times
assistant timed it to the mminute missing data substituted with average time of individual adult
28
number of offers
assistant tallied total number of times elephant given a cue for a certain behaviour
29
performance tests
after session 10, every 5 sessions approx a performance test all previous behaviours tested and required to have a passing score of 80% passing qualification "being sufficient quality to function in trunk wash" subjectively scored if an elephant failed a sequence of behaviours, shorter sequences to determine point of failure calculated by mean and standard error
30
results
4 juvenile elephants successfully learnt trunk wash, elephant 5 did not
31
conclusion
it is feasible to train juvenile, free contact traditionally trained elephants with no prior experience of SPR in Nepal to participate in trunk wash procedure voluntarily elephants performance increased from 39% after session 10 to 90% after 35v sessions
32
training sessions
elephant 2 passed final test with 25 training sessions, 10.29 min avg and 257 total training time elephant 1 30 sessions, avg 12.42 min, total 373min elephant 3 35 sessions 13.27avg min, total 389 min elephant 4 35 sessions 11.11 min, 451min elephant 5 not tested on trunk wash, 424 min total 378 mean
33
what behaviours did elephant 5 not pass
blow into bucket, desensitisation to syringe and steady
34
which elephants didnt pass steady
elephant 2 and 4
35
strengths
1. distress- ethical able to walk away if they didnt want to participate, helped reduce distress of elephants, as well was risk to mahout and trainer who could be hurt if elephant became uncooperative 2. reliability using a behavioral checklist exact operational definitions for each behaviour, increased reliability of observers decisions of fail and pass 3. validity no additional cues from mahouts important as it mean chnage in elephant was due to secondary positive reinforcement helps prove spr is successful 4. generalising to everyday life data is naturalistic setting,many distracting noises, tourists, increases scological validity, can be done in zoos and safaris
36
weaknesses
1.validity behavioural checklist operational definition of steady was to be able to hold position in various different positions. elephants were successful in steady for trunk up and trunk here but not trunk down, obtaining only a 70% accuracy while the pass standard was 80% this is important as the operational definition of steady did not reflect elephants true ability of 2 positions 2. total training time(validity) total training time included behaviours not part of the trunk wash, eg 4 elephants trained on trunk out, then realised not necessary, total train time not accurate of actual time it took to learn behaviour 3. objectivity measurement of success and failure despite operational definition required subjective interpretation of observer, they checked whether it was good enough for successful trunk wash, not just whether it matche dthe description or not. trainer may have been biased or another observer may have rated differently, lack of inter observer reliability 4. small sample difficult to generalise, specifically lack of males and adults elephant 5 could not be generalised to adults because she had a abscess on foot which made her unfocused, probably had impaired vision and/or trunk weakness
37
issues and debates
individual vs situational explanation elephant 5 only one who couldn't learn, individual difference, older, health issues, situational, trainers could have responded differently, aspects of environment were also different, young calf distracting her
38
application to everyday life
fegen et al developed a relatively safe and effective was of training elephants to cooperate during critical veterinary procedures. it can easily be adopted to teach other behaviours, this reduces need for manual restraint, drugs, decreases stress and improves well being of animals
