Q

What does the Clever Hans Effect tell us about animal perception?

A

It shows us that animals are closely memorizing subtle cues given by and learning what they should respond

Q

How does Lloyd Morgan’s Canon relate to the phylogenetic tree?

A

The more widespread a behavior, the more likely it is older and originated in a more distant common ancestor.

Q

Learning (definition)

A

Change in an subjects behavior to a given situation brought by repeated experiences in that situation provided that the change cannot be explained on the basis of native responses, maturation, or temporary states(drugs).

25
Example of classical conditioning
``` Balloon experiment US: popping balloons UR:startled CS: facial expression, counting prof. CR:tense muscles ```
26
Do the CR and the UR always have to be the same?
No. CR depends on CS not UR The CR is the preparing for the US
27
Eye blink experiment for Classical conditioning
US: puff of air UR: blink CS: tone or light CR: close eyes
28
Taste Aversion
lace food and make animals sick
29
What conditions are necessary for classical conditioning to occur?
At least 2 perceivable stimuli, Contiguity, contingency, surprise, attention
30
Blocking
Pretraining with one stimuli, and then training with 2, including the pertained. Test if animal will respond to the 2nd stimuli (they won't)
31
Overshadowing
Train with two stimuli, test with just one, and see if they respond. (nope)
32
How does blocking challenge contiguity?
Even though the CSs are both contiguous in time, one CS is still blocked from learning. This defies the idea that closeness in time always impacts response
33
S-R model of Pavlovian conditioning (classical)
An animal will form an association between the conditioned stimulus and the response (skipping the US to create the behavior)
34
CS-US Model of Pavlovian conditioning (classical)
the animal forms an association betters the CS and the US, which leads to the observed response
35
US devaluation
like taste aversion, Supports CS-US model better
36
Instrumental conditioning
the animal is learning an association between its behavior and a certain outcome
37
Conditions necessary for Instrumental Learning
Contiguity, Contingency(reliable), motivation
38
Vi
The predictive value
39
Sum of DeltaVi
the sum of associative strengths for all stimuli in trial
40
DeltaV
the change in predictive values of stimulus
41
Lambda (Y)
the asymptote of learning; strength of the US
42
Alpha i
CS salience
43
Beta i
US salience
44
Lambda minus sum of Vi
amount of surprise
45
Resocorla-Wagner model formula
DeltaVi=AlphaiXBetai(Lambda minus sum of Vi)
46
How can you make learning faster through Rescorla-Wagner Model?
by increasing or decreasing the importance or noticeability of the CS or US to the animal, ex. louder noises
47
Alpha and Beta determine...
how quickly the animal learn
48
DeltaV increases when
Surprise increases
49
Surprise decreases when...
the stimuli are not important to the animal and also with more and more pairings of the stimuli (habituation)
50
S+
Increase responses, response-> reinforcement
51
S-
Decrease responses, response-> no reinforcement or a punishment
52
Peak shift
maximum responses is not to S+, Ex. Pigeons trained to peck to 550 nm, not not 590nm. max rate of response was at 540nm
53
Perceptual category
a group of stimuli that share physical features. human language labels perceptual category with names. (frog, tree, chair)
54
Feature theory
animals learn features specific to a category
55
Exemplar Theory
perceptual categories are learned by memorizing exemplars, and novel exemplars are categorized by their similarity to learned exemplars
56
Prototype Theory
is the perfect exemplar of a category and is accessed when assessing novels stimuli
57
Circadian Rhythms:
behavior that occurs at specific times of day
58
endogenous time givers:
food light, lack of light
59
Circadian Rhythms: The good & bad
good for daily rhythms bad for longer or shorter intervals
60
Interval timing system
Allows animals to respond on the basis of specific durations
61
Weber's Law
the change in a stimulus that will be just noticeable is a constant ratio of the original stimulus
62
Scalar property
errors in timing increase as duration increases
63
temporal bisection
psychological middle is at the geometric mean
64
Analogue Magnitude (relative) system
is when you train one number then cary the numbers and other features of the test, to make sure you are not measuring absolute numbers, good for any quantity and obeys Weber's law
65
Object tracking system
tests whether an animal choses a box with more desired items than lesser (test small numbers
66
Serial ordering
is when an animal learns a list and then is asked to recall the items in the list
67
Transitive inference
when animals learn items in a sequence, and can translate the order/value from the sequence to non-consecutive items
68
Primacy effect
remembering the very beginning of a list you're trying to remember
69
Recency Effect
remembering the very last items on the list you're trying to remember
70
Dead reckoning
system that uses heading and distance to navigate, without any context clues from the environment, other than the sun compass/magnetic perception of direction. Distance is measured in steps or optic flow
71
Routes
a system of navigation that uses a set path frequently traveled by an animal, and the animal will memorize that exact path and will not deviate from it
72
landmarks
global cues that animals use to orient their positions, and it requires that the animal associate the landmark with home and make note of the relative direction and stance of home from the landmark
73
Beacon
a local cue that signals the end destination
74
Retention interval
the space of time that occurs between initial learning(T1) and the memory recall stage(T2)
75
Intertrial interval
amount of time between separate trials in learning studies. if there is a longer intertribal interval the animal uses less proactive inference
76
Encoding
the intake of perceptual information into an animals brain
77
Retention
depends on interference, and is how long an animal can keep a memory stored without it degrading
78
performance
is the degree to which the animal correctly recalls information or behaves a certain way in response to a stimulus
79
Inference
is a reduction in memory retention due to extraneous events
80
Proactive inference
is when information is already stored in the memory can interfere with the storage of new information
81
retroactive inference
is when new information my interfere with what is already in memory
82
in a visual search task, animals must locate a.
target against a field of distractors
