Cards

Term
semanticity
Definition
sounds carry meaning
Term
arbitrariness
Definition
the connection between symbols & what they represent is arbitrary (exceptions: onomatopoeia).
Term
Flexibility & Naming
Definition
we give names to things by inventing new words, and we also change meanings (i.e. monitor, cookie)
Term
Displacement
Definition
with language we are not “stuck” in the present moment, we can communicate about the past and the future.
Term
productivity/generativity
Definition
we invent sentences as we speak them, we
don’t just “replay” them like a tape recorder.
Term
morpheme
Definition
smallest meaningful unit of language (e.g., a word, or even a prefix or suffix like “ing.”)
Term
phonology
Definition
the sounds of a language. 1st-Speaker translates ideas into sounds. 2nd-listener translates sounds into meaning
Term
phonemes
Definition
basic sounds of a language, around 200, English has about 46
Term
How are consonant sounds made
Definition
Consonants: disrupting air flow
Term
variability of sounds
Definition
the phonemes coming both before and after a given phoneme influence how that one will actually sound
Term
how do we know variability of sounds?
Definition
coarticulation
Role of top-down processing, context, role of visual cues
Term
Problem of invariance
Definition
The sounds of speech vary a great deal (e.g., the “a” sound in “BAG” is different from the “a” sound in “NAG.”
Term
, how do we accurately perceive the sounds that we are supposed to perceive? Know the studies that have demonstrated this.
Definition
White noise study, phoneme restoration effect
Term
phoneme restoration effect
Definition
Subjects fill in missing information (auditory) depending on the context
Term
McGurk effect
Definition
Hearing one sound while watching lips, hearing another sound when not watching--demonstrates that visual cues help us perceive phonemes
Term
a. Knowledge of syntax: Early left-to-right approaches
Definition
Judgments of grammaticality depend on how frequently the words had been paired together in the past
Term
a. Knowledge of syntax Phrase-structure approaches
Definition
legal approach; structure tree of noun, verb, etc
Term
Why are left-to-right approaches inadequate?
Definition
Just because the sentence seems grammatical doesn’t mean it makes sense.
Term
Where do Phrase-structure approaches fall short?
Definition
Just because a sentence maps onto an acceptable phrase structure, it’s not necessarily accurate
Term
Distinction between “Deep” structure and “Surface” structure.
Definition
Surface structure is the superficial structure/appearance. Deep structure is an underlying form that contains much of the information necessary to the meaning (more abstract)
Term
Broca's
Definition
difficulty producing speech, but can still comprehend speech; crucial for syntactic processing
Term
Wernicke's
Definition
no problem producing, but cannot produce structure; crucial for meaning underlying the structure
Term
aphasias & syntax vs. meaning—double dissociation
Definition
when opposite patterns of dissociation occur, like when a person with hippocampus damage shows intact implicit but disrupted explicit memory
Term
Case grammar approach
Definition
An approach to understanding how we decide what relationships the words in a sentence have with one another. According to it, we assign roles to words based on how the words are used.
Term
Propositional theories
Definition
We represent the meaning underlying sentences in terms of their basic idea units (or propositions).
A proposition can be represented as a node with links connected to nodes representing content words; the links themselves represent the semantic roles being played by the content words.
A sentence with several propositions can be represented as a set of these propositional node structures linked together according to how they interrelate in the sentence.
Term
Support for Propositional Approach?
Definition
People tend to abstract the gist from the sentences given
Term
heuristics
Definition
rule of thumb approach
Term
availability
Definition
When we make decisions based on how easily we can access something from memory (frequency of exposure, confirmation bias, familiarity bias, salience/vividness)
Term
Representativeness
Definition
When we make decisions based on how “representative” of real-life situations something seems
Term
Simulation
Definition
1.       We judge the likelihood of a particular situation based on how easily we can imagine the situation happening that way (hindsight bias)
Term
Anchoring and adjustment
Definition
People start with an initial value that serves as an “anchor” and make adjustments to it to reach their estimate
Term
Decisions about differences—symbolic distance
Definition
the greater the distance between two things, the easier it is to decide
Term
Semantic congruity
Definition
a person’s decision is faster when the dimension being judged matches the implied semantic dimension
Term
verbal protocol
Definition
transcription and analysis of Ss verbalizations as they solve a problem
Term
Negative Set
Definition
being stuck in one mindset/approach to solving a problem
Term
functional fixedness
Definition
a tendency to use objects/concepts in only their usual and customary way
Term
behaviorism
Definition
John Watson; stimulus -> response, objective measures, replication, experimental control; B.F.Skinner; no need for theorizing about the mind, could not be objectively observed
Term
Cognitive Revolution:
Definition
3 factors: WWII, Computers, verbal Learning Research.
Term
The Information Processing Approach
Definition
Computer led to insight, information processing
Term
objective mental processes
Definition
1. Accuracy Measures (e.g., Recall Performance) 2. Reaction Time Measures 3. Eye-tracking Measures
Term
contralaterality
Definition
Right side of brain controls left side of body, vice versa
Term
cerebral lateralization
Definition
2 hemispheres are functionally asymmetric; left side language; right side spatial/face processing
Term
neuropsychological methods used to relate brain activity with mental events
Definition
1. Physical techniques (Lesions, TMS, Cellular Recording)
2. Behavioral techniques (Dual Task methods)
3. Neuroimaging techniques (PET & fMRI, ERP
Term
what type of representation do opponents of the visual imagery view argue for
Definition
Propositional Representation
Term
What is template-matching?
Definition
Matching a letter to a pre-known template in our mind
Term
Feature-detection?
Definition
Breaking an image into component features and recognizing based on which combinations are present
Term
What is selective attention?
Definition
Being able to focus selectively on something and filter out other stimuli
Term
How is has selective attention been studied in the laboratory?
Definition
Dichotic listening technique, cocktail party phenomenon
Term
What is the metaphor for thinking about selective attention in the auditory modality?
Definition
? Attention as a filter
Term
What is the metaphor for thinking about selective attention in the visual modality?
Definition
Attention as a spotlight
Term
change blindness
Definition
Ø              When you can look without seeing; we only see things we are paying attention to
Term
How do the view of attention as a limited capacity resource, the dual-task method, and the distinction between automatic and controlled processing interrelate?
Definition
If you have divided attention, you are doing automatic tasks; with limited capacity, can only attend to so many stimuli at once, using the dual-task method, therefore divided attention/automatic processing
Term
What is the Stroop effect and how does it relate to the distinction between automatic and controlled processing?
Definition
When you suppress an automatic response for another desired response; reading and recognizing stimuli tends to lead to automatic responses, but you have to suppress those to respond with controlled responses
Term
What is sensory memory & how is it shown
Definition
Ø              Sperling: partial vs. whole report of letters flashed
Term
how would one sutdy immediate memory?
Definition
Digit-span tasks, immediate recall tasks.
Term
? How does Baddeley’s working memory model describe short-term, working memory? 4
Definition
Phonological Loop Holes, Central Executive--holds Visuospatial Sketchpad and Episodic Buffer
Term
How has the dual-task method been used to obtain support for short term model
Definition
2 Visual or 2 Verbal tests are more interfering than one of each
Term
Proactive: distortions of memory
Definition
semantic integration, normalization, false memory, gist memory
Term
Retroactive: distortions of memory
Definition
leading questions, misinformation effect, imagination inflation
