Q

Language criteria

A
  1. Communicative - exchange of thoughts and feelings
  2. Arbitrary symbolism - connection between the symbol and the “thing”
  3. Regular structure - only certain arrangements have meaning. Ex. ARE and REA
  4. Structured at multiple levels - can be analyzed at more than one level. Ex. DOG ate CAT vs ate DOG CAT
  5. Generative - language users can produce novel utterances
  6. Displacement - language users can communicate about things that are not in the here and now. Ex. talk about dreams, past, and present
  7. Dynamic - expand and accommodate new stuff. Ex. jeggings, hater, unfriend

Q

Broca’s Area and Aphasia

25
Wernicke's Area and Aphasia
Area - comprehension center of the brain | Aphasia - production is intacked, comprehension is difficult
26
Non-linguistic communication components
Gesture - movements that are coordinated in the time and meaning with the context of language Discourse markers - indirectly relevant words/phrases a speaker uses. Ex. like, um Prosodic cues - rhythm, stress, and intonation that provide additional information about what a speaker is saying
27
Is ASL a true language?
Yes, It meets all 7 criteria, aphasias affect ASL, it has evolved and developed like a spoken language
28
Evolution of a language
jargon (random jumbled words), homesign (family language), pidgin (language by at least two groups), creole (mixture of different languages), language system
29
Animal communication
feelings and emotional states, warnings, mating desires, food sources
30
Confirmation bias
tendency to search for or interpret information in a way that confirms one's existing beliefs (major problem with primate studies)
31
Emotion
a person's affective state of feeling
32
Mood
extended emotional state
33
Categorical approach (models of emotion)
emotions are distinct - Ekman's Basic Emotion Theory: innate - everyone is born with 6 emotions
34
Dimensional approach (models of emotion)
emotions result from a combination of factors - Barrett & Russell's dimensional model (high/low arousal & negative/positive valence)
35
Appraisal
evaluations we make about situations relevant to our goals, concerns, and wellbeing - this determines whether we experience emotion, and which emotion we experience
36
Automatic Appraisal
non-conscious, memory-based (gut feeling)
37
Deliberate Appraisal
effortful, related to decision making
38
Types of emotion regulation
Situation Stimulus - approach desirable situations and avoid non-desirable situations Situation Modification - change the situation to alter emotional state Attention Deployment - deliberate distraction Cognitive Change - using reappraisal to change the meaning of the situation Response Modulation - continuing emotion of the situation
39
Attentional Narrowing
increased arousal leads to decreased conscious awareness of environmental stimuli
40
Forebrain
cognitive processing
41
Midbrain
consciousess
42
Hindbrain
human functions
43
Top-Down Processing
the context surrounding the stimulus will cue you into the meaning. Ex. 12 B 14 and A B C
44
Bottom-Up Processing
trying to gain meaning with something that has no meaning. Ex. black and white sploches and the distinct cow
45
4 Bottom-Up Theories
Template - take new stimulus and attempt to match it with a stored template. Ex. chair and existing matches Prototype - creating mental representations and every new stimulus gets ranked and falls into a category. Ex. tomato, fruit or vegetable? Feature Matching - break stimulus down into components, identify features, put back together. Ex. T | - T "T" Recognition by Components - geons make up objects
46
Movement filter theory
movement affects the ease of search - sometimes it helps and sometimes it inhibits
47
Attention in feature integration theory
conscious attention works as a "glue" to integrate representations of features so that the target can be detected
48
Baddeley's Working Model - why is it better than the classic view?
this is a model in which different components of short-term memory can help place information into long-term memory. This model uses both visual and auditory working memory to store info instead of using basic short-term memory.
49
Encoding specificity principle
memory is best when information available at encoding is also available at retrieval
50
State-Dependent memory
improved retrieval what the state or mind at encoding is the same at retrieval
51
Context-Dependent memory
improved retrieval when the environment at encoding is the same at retrieval
52
5 explanations for forgetting
- effortful forgetting - encoding failures - inadequate retrieval cues - decay - interference
53
Intrusion Error
information that is related to a theme of memory, but is not part of the original memory, and becomes associated with the event
54
Savings in relearning
previously presented and forgotten material is relearned faster than novel material
55
Forcing functions
limitation that prevents an action without considering key information. Ex. putting a sticky note reminder on your steering wheel
56
Judgment
assessment of likelihood, quantity or frequency (estimating costs)
57
Decision Making
making a selection from various options (investments and commitments)
58
Base rates
relative frequency with which an event occurs in the population
59
Heuristics and one bias in judgment
Representativeness Heuristic - deciding an object belongs to a category because it appears to be representative to that category Availability Heuristic/Bias - estimated frequency of a given event is dependent on how easily related information can be assessed Recognition Heuristic - the option that is most easily recognized gets selected
60
One fallacy in judgment
Conjunction Fallacy - incorrect assumption that the probability of two events occurring together greater than one of the events occurring alone. Ex. bank teller/feminist activity
61
Heuristics in decision making
Satsficing Heuristic - selecting the first option that satisfies the minimum requirements Anchoring and Adjustment Heuristic - decision is influenced by an implied starting point and subsequent adjustments
62
Bias in decision making
Hindsight bias - tendency to remember initial conditions as more suggestive of one option that the other. Ex. financial aid vs reputation
63
Fallacy in decision making
Sunk Cost Fallacy - tendency to continue an endeavor once an investment has been made. Ex. staying in a 5-year relationship because you're already in too deep
64
Multiattribute Utility Theory
we may account for all attributes of all possible options and determine the best choice. Ex. excel sheet with every specific pro and con
65
Bounded Rationality Principle
decision making is only partially relational due to limited information and processing resources
66
Framing
reaction to a particular choice differs depending on how the options are presented. Ex. advertising and how they present what they want to sell
67
Loss aversion
sensitivity to potential losses rather than potential gains during decision making
