Animal Cognition Flashcards
Anthropomorphism
attributing human characteristics to animals
Anthropocentrism
viewing animals from our own, human, perspective
Mind/mental life:
behaviours and operations (including perception, simple behaviour, complex cognitions)
Thought
•Intelligence: rank ordering? problem solving
•Cognition: behaviour
Darwin’s mechanism for evolution
Variation (many offspring, which are variable) = Selection (some offspring survive to reproduce)
The outcome is adaptation (animal’s suitability to environment)
Behaviour and psychology also subject to evolution
Will be commonalities between species
Comparative psychology
George Romanes
Animal intelligence, 1882
•Collection of anecdotes about intelligent behaviour
Now… Animals differ in their intelligence, one is not more intelligent than the other
Conwy Lloyd Morgan
Could open a gate
Reasoning vs trial and error
Performance improved over time = trial and error learning
Lloyd Morgan’s canon
1894
“In no case may we interpret an action as the outcome of the exercise of a higher psychical faculty, if it can be interpreted as the outcome of the exercise of one which stands lower in the psychological scale.”

Clever Hans
Able to answer questions (e.g., arithmetic)
Hans was responding to external signs…
But… “the horse–in so far as it was at all possible to decide–never looked at the persons or the objects which he was to count, or at the words which he was to read, yet he nevertheless gave the proper responses.” (Pfungst, 1911).
Presence of experimenters is important to think about in animal studies
(experimenter should not be sensed or should be blind to answers)
Perceptual worlds
Perceptual abilities vary between species
The world you experience is due to the processing ability of your brain
This is important when researching animal behaviour
Vision
Colour
•Humans have 3 colour receptors (blue, green, red)
•Other species can see more of the spectrum than humans
•Bees: green, blue, ultraviolet (see Hempel de Ibarra, Vorobyev, & Menzel, 2014)
•Birds: e.g., blue tits perceive UV
(Hunt et al., 1998),
pigeons have >6 colour receptors
Vision
Polarization
- Orientation of the oscillation of the waves
- Some animals can detect this and use it as a compass – polarization of light changes with the position of the sun.
- This even works on cloudy days
- Shown that many invertebrates are sensitive (see next lecture) & some birds and fish
Smell
Survival: Find food, avoid predators
Communication: define home range,
attracting mates, recognising
individuals,
Dogs
Can identify an individual odour in mixtures of odours (< 11 odours in a mixture with 100% success).
Detection of illegal substances, food, explosives, disease (cancer; Jezierski, Walczak, & Gorecka, 2009)
