Q

why study animals?

A
  • Psych is the science of mental life (James, 1890)
  • Helps us to understand humans (learn more about our own psych)
  • Animal welfare - If we know about their mental life, give them a good life

Q

darwin

A
  • natural selection, variaiton
  • Outcome is adaptation (animal’s suitability to environment) - Psych & physical traits
  • Beh & psych also subject to evolution
  • Darwin observed commonalities between species’ mental characteristics

Q

conway llyod morgan

A
  • Performance improved over time = trial & error learning
  • Arguing for better explanation & study of animal intelligence
  • Not intelligent beh by the animal but trial & error learning

Q

morgan’s canon

A
  • Use the simplest explanation
  • Explaining beh by simple processes
  • Questionable what higher & lower scale means
  • Like Occam’s razor

tinbergen

A
  • things need to look at if we want a complete explanation of beh
  • function

Q

brain size

comparing cog abilities

A
  • cephalization index (K)
  • size of brian relative to body size
  • higher value = larger than avergage brain for body size
  • low values: rats, primates
  • high value: dolphin, humans

Q

learning speed

comparing cognitive abilities

A
  • Simple instrumental conditioning task
  • Diff for diff species e.g. rats=lever, fish=push rod
  • Respond –> reward
  • Measure how many rewards needed before criterion reached
  • K and rewards to criterion don’t seem to fit together
  • Rats with small K & humans with larger K have roughly the same rewards to criterion

Q

learning concepts

comparing cog abilities

A
  • look at learning on trial 2 (when discrimination is solvable) after a num of problems
  • most animals improve with more tasks done
  • but may depend on lifestyle - dunnarts reach 90% after 12 problems, need to quickly learn about signals in environment

Q

perceptual diffs between animals

A
  • vary between species
  • world experienced due to processing ability of brain & nervous system (needing correct receptors)
  • important when researching animal beh - need to be aware of what it can discriminate

Q

colour

diffs in animals

A
  • humans: 3 colour receptors (RGB)
  • bees: green, blue, UV
  • blue tits: UV
  • pigeons >6 colour receptors
17
Q

uses of smell

animals

A
  • survival e.g. food & predators
  • communication e.g. attracting mates, recognising inds
18
Q

dogs using smell

A
  • Can identify an ind odour in mixtures of odours: <11 odours in a mixture with 100% success
  • Detection of : illegal substances, Food, Explosives, Disease - cancer, covid
19
Q

hearing

diffs in animals

A
  • Sound = vibrations in the air
  • Other animals can hear more than humans
  • Most animals just listen - others can create and then listen for navigation (echolocation)
20
Q

echolocation

A
  • bats produce sound & listen to echoes
  • flying in dark, tracking & catching prey
21
Q

animals sensitive to magnetic fields

A
  • Pigeons
  • Bats
  • Migrating fish
  • Bees
  • Ants
  • Cattle
  • Sea turtle

use magnetic fields to be able to navigate places

22
Q

What conclusions can be drawn from the clever hans story?

A

We should check methodology of studies to ensure clever hans effects are not present

23
Q

Animals’ different perceptual abilities suggest what?

A

Perceptual abilities are adaptations to the animals’ environment

24
Q

why do animals communicate?

A
  • Long term - to survive & reproduce
  • Short term - alarms, food, mate attraction
25
Q

honeybee dance

von frisch

A
  • food <100m = round dance (turn circle left then right)
  • food >100m = waggle dance (figure of 8, tells direction & distance)
26
Q

vervet monkeys

alarm calls

A
  • 21 distict messages
  • 3 major predators = leopards, eagles, snakes
  • seyfarth et al played calls when no predator around but still responded
  • leopard call = run up tree
  • snake call = stand on hind legs to look for them
27
Q

meerkats

alarm calls - manser (2001)

A
  • diff alarm calls depending on type of predator: aerial, terrestrial, recruitment
  • calls also include info about level of urgency
  • CC - learning sound predicts something important
28
Q

defining language

pearce (2008)

A
  • arbitrariness of words (no link between sound & meaning)
  • semanticity
  • displacement (communication about events distant in time/space
  • productivity (structured according to rules but can be used flexibly)
29
Q

teaching human language to apes

A

use ASL

30
Q

gardner & gardner (1969)

teaching apes human language

A
  • shaping & instrumental conditioning
  • 132 signs after 5 yrs
  • nouns, pronouns, verbs
31
Q

nim

teaching apes human language - terrace et al. (1979)

A
  • 125 signs
  • produce linear combinations (utterances)
  • 1.1-1.6 words combined
32
Q

visual symbols

teaching apes language

A
  • trained to use keyboard - Don’t have to rely on humans training & interpretating
  • Symbols (lexigrams) have symbolic value but are arbitrary
  • Plastic tokens (Premack) also arbitrary
  • Rivas (2005) - studied sign use by chimps, 86% requests, No structure or sentences within the signs
33
Q

dolphins & sentences

herman et al. (1984)

A
  • Trained to understand gestures
  • Displaced reference tests: Object - action (81.4% correct)
  • Learned 50 signs
  • Semantically reversible sentences (69 sentences), meaning different but uses same words, above chance level of accurate performance
