Q

What are two kinds of learning and their definitions?

A

Non associative-
Situation independent; single action for when task is stationary or best action when non stationary; single stimulus

Associative-
situation dependent; actions best for situation; relationship between two stimuli

Q

Types of non associative learning.

A

Habituation

  • stimulus becomes less effective the more times org responds
  • distinguish between novel stimuli and others
  • response to repeated stimulus decreases over time
  • ex: don’t hear AC after it’s been running for a while

Sensitization

  • Response increases with harmful stimuli
  • One stimulus heightens response to other stimulus
  • ex: people jumpy after disasters

Q

Types of associative learning.

A

Classical conditioning

  • links two or more stimuli and events
  • famous- dog and bell from Pavlov; bell(no response)—> bell+food (response) —> bell(response)
  • E1- conditional stimulus (bell)
  • E2- usual stimulus/ reinforcer (food)

Operant conditioning

  • animal has to do something to get reward
  • if Rat pushes button then it gets food
  • consequence of behaviour is food

Q

What’s the general process theory?(GTP)
What’s principle of equipotentiality?
Are these true?

A

GTP is E2 and E1 at same time
E1 more intense meaning faster learning
E2 increases which causes faster learning

Ep is anyone can learn anything

Aren’t true

Q

What has come from nature vs nurture debate?

A
  • Psychologists simplistic view from simple approach
  • Ethologists more natural
  • Meaning, we can’t know for sure how much of behaviour is genetic or env. Both important

Q

What are three types of receptors?

A

1) Enteroreceptors- internal state of org
2) Proprioreceptors- relationship between body parts
3) Exteroreceptors- detect things outside body

Ex: lift cup ; arm says cup is half empty (prop) and eyes say it is half empty (extero)

Q

What is sensitivity vs resolution?

A

Sensitivity

-direction of stimuli dictates direction of movement

25
What are mechanical stimuli?
Touch Vibration Sound
26
What’s a sense cell?
What the stimuli triggers
27
What do vibrations allow animals to sense?
Size of prey | Attract mates
28
How is sound perceived?
Ear converts sound waves to action potential
29
What can sound show?
1. Direction of sound 2. Intensity 3. Frequency of sound (women have higher frequency than males)
30
Sensitivity and resolution in sound?
Sensitivity- how high or low animal hears Resolution- how well you can discriminate between frequencies
31
How do humans hear?
``` Sound hits eardrum Causes movement in three bones Hits oval window Fluid vibrations Hair in ear detect vibrations Send signals to brain of frequency ```
32
How do bats echo locate without damaging ears?
Can uncouple inner ear bones
33
Do low and high frequency sounds travel far or short?
Low far | High short
34
Active vs passive stimuli
Active- sound | Passive- vision
35
What’s electro sense?
Only in water | Detect diff change in fluid depending on object
36
Two types of olfaction
Taste- short range | Smell- long range
37
What info is provided by senses?
Directionality and source
38
What’s motivation?
``` Force behind seeking of a consumultary stimulus Force behind a behaviour Sex Thirst Food ```
39
Three types of motivation studies?
Observation -Watch behaviour to stimulus Manipulator -stimulate manually and then watch (cut nerve and see what happens) Modelling 1)flush toilet model- interaction between motivation and stimuli 2)graphical model High mot= less stimulus needed Low mot = more stimulus needed
40
How are hormones related to motivation?
Usually reproduction Hormones are internal motivation for behaviour Help tell time
41
What is communication?
- analyzing signals which produce certain activity and circumstance to which behaviour happens - only occurs when response from receiver is altered - interaction between signal and response
42
Two categories of communication
1) graded - analog - variability in signal - how wide a dogs mouth is open 2) discreet - digital - on or off - dog is mean or not mean
43
What is enrichment? | What are the six forms?
Method animals use to add info to signals they put out. 1) Fading time - how long for signal to fade out or in 2) Distance - how far signal travels 3) Duration - how long something does something 4) Composite signals - signals A B C - some signals fit together; some have sequences 5) Metacommunication - communication of other acts of communication - nonverbal cues 6) Context - situation communication is in - same signal in diff contexts have diff meanings
44
Four ways to analyze communication?
1) Function 2) Evolution 3) Channel 4) Cost and benefit
45
What are four functions of communication?
- message- basic unit of communication 1) Recognition- Enable recognition of each other and self 2) Danger- alarm calls to warn each other of danger 3) Assembly and recruitment- calling members of group to do something (assembly) and using signals to direct member to specific spot (recruitment) 4) Sexual behaviour- advertisement, courtship, bonding, copulation, post copulation
46
What are the two origins of communication?
1. Semanticization- more useful for communication 2. Ritualized- how much behaviour to send signals - movement altered to make it more effective
47
How are channels used in communication? (Five)
Nature of signal 1) Chemical - pheromones - cheap, long range, lifespan of signal long - last long time to hard to switch signals 2) Acoustic - flow around obstacles, low Cost, range, simple to make, fades quick, rapid transfer - sound is directional, complex to receive, can eavesdrop 3) Tactile - Intimacy she orgs know each other 4) Visual - directionality, fast response, - only useful under light, not useful by self 5) Electrical - prey detection - voltage gradient detectable - works in dark, no eves-dropping, flow around objects - only good in water - short range
48
How are coats and benefits used in communication? Two approaches
Economic approach Optimal foraging -how animals feed to maximize energy needs
49
Two major costs to communication?
Predation | Energetic costs
50
How to measure Energy use.
Measure oxygen consumption and use stable isotopes
51
What is evolutionary stable strategies?
-When behaviour is adopted by an individual it can’t be invaded by another behaviour
52
How would evolutionary stable strategies effect evolution?
Depends on what competitor is doing to effect evolution
53
How does an individual decide fight or flight?
Competitors strength and individuals strength
54
Why don’t individuals cheat?
Hard to fake strength
55
Two ways animals exploit others?
Manipulation -Actively changing victims behaviour Mind reading - Knowing what victim is going to do - Predict things from communication
56
How are non selfish behaviours explained? (4 altruism hypothesis’s)
1) Mutualism 2) Deception- receiver tricks indv that does altruistic behaviour 3) Kin selection- parents do things that are benefitted to their offspring (genes passed down) - relatives do this too - coefficient of relatedness - siblings may help parents raise young - need to recognize kin 4) Reciprocal Altruism - Indv A helps B and gets reciprocated at later time - works when opportunity is high that two indv will meet again - Vampire bats
57
Explain altruism of social insects
Helps queen breed All share genes Females are sterile so they help mother Offspring will pass on genetic info by helping mother
58
What does natural selection favour?
Individuals better adapted to environment
59
Ethology vs psychology and when the converged
Ethology is natural, not experimental and causal Psychology is lab controlled experiments. Framework for causal factors Converged when Darwin’s theory of evolution and to be
60
What are the ways ethologists vs psychologists think animals behave a certain way?
Ethology- what causes the behaviour and stimuli? -why does natural selection maintain behaviour? Psych- how does behaviour develop? -what’s the evolutionary history?
61
What are two ways of looking at evolution of behaviour?
Proximate - how questions - genetics - learning ultimate - why questions - evolutionary causes (advantage)
