1
Q

If the US and CS are repeatedly paired, will learning occur?

A

No, not always.

CS needs to be attended to and US needs to be unexpected/surprising

Q

Explain the Rescorla-Wagner model.

A
  • Explains and predicts changes in associative strength in different situations
  • It is the strength of connection between internal representations of CS and US which determines the strength of CR

Q

When do you learn most about the association between the US and CS?

A

In the first trials compared to the later trials of an experiment.
You don’t learn an equal amount about that connection in each of your trials.

Q

Can animals understand abstract properties (e.g. rigidity, connectedness, gravity) that explain how objects behave and use that understanding to solve problems without trial and error learning?

A

Trap tube task:

  • Most animals fail
  • Individual animals who pass seem to rely on trial and error learning about perceptual features rather than functional understanding

Q

What negatives are there from using the trap tubes to test animal cognition?

A
  • Inverted trap tube is not a good control as adult humans also continue to avoid the trap when not functional
  • Tool is a confound but chimpanzees can pass modified versions

Q

Explain habituation in animals.

A
  • Memory of stimulus 1 formed
  • If subsequent stimuli match memory for stimulus 1 then there is a small response to it
  • If memory not maintained or disrupted, there is no habituation.
  • Hab requires existence of memory of repeatedly presented stimulus

34
Q

Are primacy or recency effects more common?

A

Recency

35
Q

Why do we believe primacy effects take place?

A

Due to verbal rehearsal and the role of verbal rehearsal in consolidating that memory
- However animals don’t engage in verbal rehearsal because they don’t have language

36
Q

What is metamemory?

A

Awareness of strength, accuracy, and accessibility of certain memory.

37
Q

How long have pigeons LTM shown to extend to?

A

Above chance after 2 years

38
Q

What 2 different theoretical accounts are there of LTM?

A
  • Consolidation Theory

- Retrieval Theory

39
Q

What is consolidation theory?

A

a time-dependent process by which recent learned experiences are transformed into long-term memory, presumably by structural and chemical changes in the nervous system

40
Q

What is retrieval theory?

A

theory as to why we cannot recall from long term memory. The suggestion is that internal (such as mood state) and external (such as temperature and smell) cues can help facilitate recall of a long term memory

41
Q

What is a neophilic?

A

A fondness or obsession with change - they like to go and explore novel things

42
Q

What is the ecological view in comparing animal memories?

A

Species that depend on memory for survival will have evolved special abilities

43
Q

What is the general process view in comparing animal memories?

A
  • Similar mechanisms in all species

- Demands of ecology determine which stimuli an animal pays more attention to

44
Q

What is cooperation?

A

A behaviour which provides a benefit to another individual.

Two or more individuals coordinate their behaviour for common or mutual benefits

45
Q

What types of cooperation are there?

A
  • Cooperation with kin
  • Mutual cooperation
  • Reciprocal behaviour
  • Pseudo-reciprocity
46
Q

What organisms cooperate with kin?

A

Social insects cooperate to build hives/nests, care for young, and gather food.

47
Q

What is mutual cooperation?

A

Cooperative behaviour that provides immediate gains for all PPS

48
Q

What are the roles in chimpanzee cooperative hunting?

A
  • The driver
  • The blocker
  • The chaser
  • The ambusher
49
Q

Give examples of intentional communication.

A

Hand clapping
Stomping
Drumming on the bars

50
Q

What is the definition of reciprocal altruism?

A

Cooperative strategy where individuals alternate roles as actor and recipient

51
Q

Why is reciprocity demanding?

A

Because it requires keeping track over long periods of time

52
Q

What is pseudo-reciprocity?

A

Individuals take part in reciprocity for a direct immediate benefit e.g. ant-butterfly mutualisms

53
Q

What is the additional type of cooperation?

A

Helping

54
Q

What is the definition of helping?

A

involves immediate costs for the actor and yields benefits exclusively for the recipient

55
Q

What is helping behaviour?

A

Assisting an unrelated individual even when you receive no rewards

56
Q

What are key differences in human vs non-human cooperation?

A

Humans are proactive and shared - we know we are working towards a shared am. But non-humans are reactive and we aren’t sure is other species can share attention.

57
Q

Why do animals need to know where they are?

A

Need:

  • A safe home
  • Food
  • Mates
  • Need to know how to navigate between these things
58
Q

What short-distance ways can animals navigate?

A
  • Chemical Trail
  • Pheromone Trail
  • Urine Trail
59
Q

What is route learning?

A

Memory chain of motor responses that are needed to go from A to b

60
Q

What is dead reckoning/path integration?

A
  • Egocentric
  • Internal sense of direction and distance to goal from current position
  • Keep track in relation to goal
61
Q

How is distance calculated by ants?

A
  • By the number of steps

- Direction relative to the sun

62
Q

Is path integration possible without self-generated movement?

A

Yes in geese

- Visual info is key for keeping track of distance and direction from starting point.

63
Q

How can animals use landmarks to navigate?

A
  • Single landmarks
  • Template matching
  • Multiple landmarks
64
Q

What is template matching?

A

retinal snapshot of landmark at goal

65
Q

How do animals use compass bearings to navigate?

A

If relative position of landmark stays the same but degrees from north varied randomly in training, the bees don’t find the goal

66
Q

How do animals use sun/star navigation?

A
  • requires knowledge of the path of sun or stars
  • internal clock
  • many use sun compass or celestial compass
67
Q

What is a cognitive map?

A

Internal representation of a plan of space, where spatial relationships between objects in the environment are represented

68
Q

What is a topographical/network map?

A

Representation of familiar routes between landmarks

69
Q

What is a Euclidean/vector map?

A

Representation of space that allows computation of direction and distance from any other place to any other know place

70
Q

What theories are there for primates navigating in the wild?

A
  • Walk in a straight line rule
  • Topographical map
  • Euclidean map
71
Q

Explain the walk in straight line rule for primates.

A

Generates linea paths and in a resource-rich environment this might be effective

72
Q

Explain topographical mapping in primates.

A

Variation in speed of travel.
Approavh known resources from same direction/via same landmarks
Most efficient in core of territory where landmarks are very well known

73
Q

Explain euclidean mapping in primates.

A

Approach known resources from different directions.

Initial direction of travel towards recourse is not adjusted - set off on most efficient path from the start

74
Q

Where are place cells?

A

Hippocampus

75
Q

What do place cells respond to?

A
  • specific places
  • places relative to landmarks
  • place in room regardless of landmarks
  • does NOT respond to compass bearings
76
Q

When do head direction cells fire?

A
  • When head is in certain direction in relation to landmarks

- do NOT respond to magnetic fields or compass bearings

77
Q

How do animals use cues for direction in long distance navigation?

A
  • Magnetic fields
  • Sun compass
  • Polarized/UV
78
Q

How do animals use cues to altitude in long distance navigation?

A
  • Air pressure
79
Q

What is homing?

A

Returning to home base regularly

80
Q

What is olfaction?

A

Sense of smell

81
Q

How do animals use landmarks for long distance navigation?

A

Useful but not necessary

82
Q

What is migration?

A

Long distance seasonal travel (usually 2 journeys per year)

83
Q

When animals move, which spatial cues do they use?

A

Different kinds of spatial info are processed or learnt in different circumstances
- On basis of info available decision as to direction and distance of travel taken
