Q

What is dual coding theory? How does it help explain the correlations between visual imagery and memory for concrete/abstract words?

A

theory that info is represented through sensory information and verbal information.
explains correlation with memory and abstract v, concrete words because concrete words represent sensory and verbal info, while abstract words are represented only through verbal, making concrete words align more with how we code things into LTM

Q

What do Shepard & Metzler’s mental rotation studies suggest regarding imagery v. perception?

A

because the total degrees rotated correlates with how long it takes to identify, we conclude that individuals rotate them in their mind, indicating that imagery and perception share mechanisms

Q

Kosslyn, Image scanning: How did the distance between two objects on the map influence the time it took to mentally “travel” between the two objects? What does this suggest about imagery v. perception?

A

They found that the further apart two objects were, the more time it took to mentally travel between them. This suggests that visual imagery works similarly to perception.

Q

Confusing perception & imagery, Perky 1910

A

Q

What does topographic map refer to in the context of visual imagery and the neural activity they generate?

A

correspondence between the layout of a visual stimulus and the activity it generates such that specific locations on visual stimulus cause activity at specific locations next to each other on the cortex. both imagery and perception result in topographically organized brain activation

Q

For objects visualized mentally, how does the size of an object influence the location of neural activity in the visual cortex?

A

like with perception, small objects activate the back of the visual cortex and large objects cause activity to stretch forward.

Q

What is a reasonable conclusion regarding the overlap in cognitive/neural mechanisms used for visual perception v. visual imagery?

Q

What are some differences between animal communication and human language?

A

Q

Define discreteness and duality of language

A

discreteness - language is comprised of acoustically distinct units (phonemes)
duality - language is organized at 2 levels
- individual distinct sounds
- combinations of sound that convey meaning (morphemes)

Q

Define phonemes

A

units of sound (vowels and consonants)

27
Q

Define morphemes

A

basic units of meaning (words and meaningful parts such as suffixes and prefixes)

28
Q

Define syntax

A

grammatical rules that govern how words are put together into meaningful strings (phrases/sentences)

29
Q

Define extralinguistic information

A

information that isn’t part of the content of language but is critical to interpreting its meaning (context, nonverbal cues)

30
Q

What purpose does infant babbling serve?

A

is done to develop control of vocal tracts

31
Q

What does it mean to overextend and underextend word meanings?

A

overextend example: calling all dogs Kaizy
underextend example: thinking that grandma only refers to YOUR female grandparents

32
Q

Differences in bilingualism and learning a second language early v. late

A

If learned early, same brain areas are used for both languages
If learned later, different brain areas are used for each language

33
Q

What is the lexicon?

A

semantic meaning of all the words we know

34
Q

What is the word frequency effect?

A

we are able to access the meaning of high frequency words faster than low frequency words

35
Q

Why is it easier to understand words in context?

A

because word pronunciation varies among people and varies based on mood, tone, and words before and after. thus understanding individual words is much more difficult than understanding a whole sentence in recordings

36
Q

What is speech segmentation?

A

although there are no pauses between words in a sentece, we can perceive individual words

37
Q

What are content and function words? Which do we pay more attention to when reading?

A

content words - actively convey meaning
function words - play structural role
pay more attention to content words

38
Q

Levels of text presentation (describe each):

A

surface form - exact wording
textbase - meaning of individual sentences
situation model - integration of meaning across the entire passage, draws upon prior knowledges (gist of passage, use inferences)
ex. John is hitting a nail so he is likely using a hammer

39
Q

What are speech errors? Why are they of interest in understanding speech production?

A

speech error - an utterance that deviates from its intended form
we are interested in them because they inform us of how intended speech production is formed. shows it requires complex motor coordination and existence of speech planning that takes place before speech is produced
suggests that phonemes and morphemes are planning units for speech
aspects of speech are addressed in separate stages

40
Q

What is an anticipation speech error?

A

when a later segment takes the place of an earlier segment
leading list = reading list

41
Q

What is a perseveration speech error?

A

when an earlier segment takes the place of a later segment
nick of nime = nick of time

42
Q

What is a blend speech errors?

A

when 2 words are blended or fused into a single word
likely the result of choosing between 2 words when planning a sentence
lection/lesson = lection

43
Q

What is speech planning?

A

the process of turning a thought into a sequence of words meant to express the thought

44
Q

What does Broca’s aphasia impair?

A

causes difficulty producing fluent speech (and writing) as a result of brain damage
- can form thoughts normally but have difficulty expressing them.
- impairs speech planning and motor articulation

45
Q

Define problem solving

A

requires finding ways to get around obstacles to reach our goal state

46
Q

What is the general focus of the Gestalt approach to problem solving?

A

how a problem is represented in the mind and how solving a problem involves reorganizing or restructuring this representation

47
Q

What does restructuring refer to?

A

process of changing a problems representation in the mind in order to make it easier to solve

48
Q

What is insight?

A

a sudden comprehension, realization, or problem solution that involves restructuring to yield an interpretation that was not immediately obvious.

49
Q

What is the difference between insight v. non-insight problems

A

Insight problems are solved via a sudden realization
Non-insight problems are solved via linear step by step process

50
Q

Define fixation

A

tendency to focus on specific characteristics of the problem that prevents one from arriving at the solution

51
Q

What is functional fixedness?

A

a tendency to fixate on familiar functions and uses of an object, which leads to ignoring alternative uses that could be more conducive to solving a problem

52
Q

What is a mental set? (water jug problem)

A

preconceived notion of how to approach a problem based on what has worked in the past
ex: doing the known B - A - C instead of A + C because you are focused on previous problem’s solutions

53
Q

Define initial state

A

conditions at the beginning of a problem

54
Q

Define goal state

A

solution to the problem

55
Q

Define intermediate state

A

conditions after each step is made toward solving a problem

56
Q

Define operators

A

actions that take the problem from one state to another, usually governed by rules

57
Q

Define problem space

A

all possible states that could occur when solving a problem

58
Q

Define means-end analysis

A

a way of solving a problem in which the goal is to reduce the difference between the initial and goal states

59
Q

Define subgoals

A

small goals that help create intermediate states that are closer to the goal state

60
Q

What is analogical transfer?

A

transferring experience in one problem to solve another, similar problem

61
Q

What is a target problem and a source problem?

A

target - problem you are trying to solve
source - problem that is similar to the target problem, and illustrates a potential solution

62
Q

What is Duncker’s radiation problem?

A

A problem that illustrates analogical problem solving. Participants goal is to save the patient by shooting low intensity radiation from multiple sides to kill tumor. This solution is very difficult to come up with. However, success triples when participants are given the fort analogy.

63
Q

What are some difference between expert and novice problem solving?

A

experts have more knowledge and organize information differently. they also spend more time analyzing problems before attempting to solve

64
Q

Does expertise in one area confer any advantages to problem solving in other areas?

A

no, only an advantage in their field. even have difficulty imagining new systems of inquiry
