Animal Cognition: An introduction Flashcards
what is cognition? Shettleworth, (2010)
the mechanisms by which animals acquire, process, store and act on information from the environment
Why do we study animals?
- Psychology is the science of mental life, James (1890) therefore need to learn about animals and humans
- Helps us to understand humans i.e. the evolutionary development
- Animal welfare, help to make sure we have good standards of animals welfare
what is anthropomorphism?
attributing human characteristics to animals
what is anthripocentrism?
viewing animals from our own human perspective
charles Darwin and the mechanism of evoultion
- Variation - there are many offspring which are variable
selection - some offspring - survive to reproduce due to advantageous characteristics from the variation
- the outcome is adaptation (animal’s suitability to environment)
what was Charles Darwin’s contribution to psychology?
- behaviour and psychology also subject to evolution
- Darwin observed commonalities between species’ mental characteristics
- beginnings of comparative psychology
what did George Romanes do?
- write a book on animal intelligence in 1882
- collection of anecdotes about intelligent behaviour
what did Conway Lloyd Morgan do?
- argued for better study of animal intelligence
- his dog called Tony could open the gate in their garden by moving his head in a certain way to lift the latch
- performance improved over time and this was concluded by trial and error learning
what is Morgan’s Cannon? 1984
- explaining behaviour using simple processes
- use the simplest explanation
what are Tingbergen (1963) 4 questions?
- Function
- Phylogeny (evolution)
- Ontology (development)
- mechanisms
How did Thorndike (1898) contribute to animal cognition studies?
- experimental methods used in animal studies
- developmental approach
How can we compare brain size?
Cephalization index (K)
- size of brain relative to body size
- higher values mean a larger than average brain fro body size
- rats=0.1, primates and whales = 0.2-0.3
- dolphins = 0.65, humans = 0.89
what can we learn about learning speed using the cephalization index? Pearce (2008)
- a simple instrumental conditioning task
- respond → reward
- measure how many rewards needed before criterion reache
what can we learn about concepts using the cephalization index? Wynne & Udell (2013)
- look at learning on trail 2 after a number of problems
- most animals improve and get more food the more tasks they do as they learn what shapes get them food
- However, may depend on lifestyle – Dunnarts reach 90% after 12 problems. They forage in open areas and need to quickly learn about signals in the environment.
what are some issues with testing with animals?
- Learning with some stimuli seems easier than with other stimuli, e.g., it is easy for a rat to learn to press a lever for food, but not to press a level to avoid a shock.
- Contextual factors (Bitterman, 1965) says this is to do with sensory, motivational, and motor processes that influence learning
