1
Social learning and culture Forms Audio-vocal learning Consequences –Rate of transmission –Traditions and culture
2
Forms of social learning Local enhancement –Locate foraging sites by attending to others Social facilitation –Animals feed faster in a group Observational learning (copying) –Observer modifies behavior after demonstrator Imitation –Observer matches behavioral action and goal Teaching –Demonstrator performs behavior only to naïve observer
3
Local enhancement in cliff swallows
4
Social facilitation in ravens
5
Diet transfer in rats Observational learning
6
Diet tradition in Norway rats
7
Imitation in rats?
8
Pine cone learning in rats, a natural example of imitation?
9
“Teaching” to mob
10
Observational conditioning
11
Social learning dilemma Observational learning reduces costs by minimizing errors. Do we expect everyone in a population to use observational learning? No, because someone has to figure out the correct behavior first. Asocial learners = producers, social learners = scroungers Expect social learning to be used selectively
12
Scrounging can interfere with skill acquisition
13
Song learning requires a learned “template”
14
Acquisition of template can be influeced by social experience Live tutor present
15
Dialects in white-crowned sparrows - a cultural tradition?
16
Whistle sharing in bottlenose dolphins Males form alliances that persist for many years Dolphins can imitate sounds Alliance partners share whistle types
17
Greater spear-nosed bats learn group distinctive calls
18
Vervet alarm calls
19
Alarm calls refer to predators
20
Development of vervet alarm calls
21
Vervet infants learn when to call
22
Rate of change depends on form of transfer
23
Observational learning can lead to epidemic rates of change
24
Cream stealing by blue tits
25
Observational learning can create traditions (culture)
