Social Learning Flashcards
What is Social Learning? What are the benefits of this?
The acquisition of knowledge or skills from a conspecific. A route to learning while avoiding the costs associated with trial and error learning. The behaviour or new information should be retained by the observer in the absence of the demonstrator.
What are the 3 forms of social learning?
- Stimulus and local enhancement
- True imitation
- Mimicry
Define stimulus and local enhancement
Attention is drawn to a particular object or area of the environment by a conspecific.
Define true imitation
Learning a new behaviour from seeing it done - brings immediate benefit to the individual
Define mimicry
Learning an new behaviour from seeing it done, but without any immediate benefit to the individual.
Which form of social learning is most cognitively demanding? Which is least?
Stimulus enhancement is least cognitively demanding
Mimicry is most.
What type of behaviour may be confused with social learning but isn’t?
Social FACILITATION - eg. feeding when others feed and flocking behaviour
This is strengthening of a previously well learned response due to presence of others
What types of stimuli may mediate social learning?
Visual
Olfactory
Auditory
Give an example of social learning via olfactory cues
Rats are more likely to eat food if they smell it on a conspecific. NB: do not learn aversion socially (conspecific can be ill/unconcious, will still ^food intake.
Give an example of learning via auditory cues
Young songbirds cannot learn to sing unless they hear an adult male when they were young (sensitive period)
- actual birds more effective teachers, and produce more variable songs than tapes
- bias shown to tutors - more salient males ^ effectiveness of learning
How does vocal mimicry evolve?
From song copying - birds that can song copy have a neural template to compare sounds they hear to sounds they produce
- relaxation of sensitive period allows lifelong learning
- attention broadened to a wider set of stimuli
What has developed alongside vocal mimicry?
Physical mimicry - eg parrots (Moore, 1992)
Give an example of stimulus/ local enhancement. How does this function?
eg. Rats stripping pine cones (Terkel, 1996)
Presence of demonstrator ^ salience of a location or stimulus
Subsequent acquisition of same behaviour is via instrumental learning
What is imitation? Is this cognitively demanding?
Exactly copying the motor patterns of demonstrator.
Highly cognitively demanding
How may stimulus/local enhancement be distinguished from imitation?
Chimps twist v poke box (Whiten, 1998)
Give an example of a field observation and how ambiguous the interpretation of the form of social learning is.
Chimp putting bowl on head
- Seen someone putting things on head, tried it - kept head dry
- Seen someone putting a bowl on head - copied exactly - kept head dry
- Copied someone putting a bowl on their head but with no purpose or direct gain to the chimp
Give an exemplar study to distinguish stimulus/local enhancement from imitation
Rats with a joystick - found to push in the same direction relative to demonstrators body, therefore it is imitation (Heyes and Dawson, 1980)
What must be considered when explaining behaviour as a social learning model?
That lower cognitive abilities cannot explain the phenomenon - novel stimulus may attract attention and then they learn by trial and error for example.
What factors influence social learning abilities?
ID of demonstrator Dominance Age Salience (eg. bigger/brighter comb) Presence of other social learners - producers/scroungers
DONT UNDERSTAND Explain the producers/scroungers phenomenon. Give an example.
Indiscriminately copying others behaviour is not adaptive - it is only adaptive when scroungers are uncommon
EG. Sparrows - dominant sparrow allows some subordinates to forage nearby
Dominants scrounge from subordinates and protect them from other dominants
Give two examples of animals that will/will not pay attention to certain types of individuals.
Geese will learn from humans
Hens will not pay attention to cockerels
What are the 3 criteria for “teaching” to be occurring? Who developed these?
Teacher alters behaviour only in presence of naive observer
Modified behaviour incurs a cost/no benefit to the teacher
Naive observer squires skills more quickly/new skills it would have not otherwise developed
Caro and Hauser 1992
Give 3 examples of animals teaching.
- Hens teach their chicks to forage by over exaggerating behaviour (NIcol and Pope, 1996)
- Felines and whales provide semi-dead prey to teach hunting skills (Rendell and Whitehead, 2001)
- Chimps teach young to crack nuts using shammer and anvil (Boesch, 1991)
Define adaptive behaviour
Behaviour that fosters effective/successive individual interaction with the environment
Why is social learning studied?
Transmission of abnormal behaviour eg. tail biting, feather pecking (or other behaviour, eg. blue tits pecking through milk tops)
Cognitive abilities affect housing and husbandry
Have cultures been noted in animal populations?
Chimps - tool usage differs between areas
