varieties of psycholinguistic experiments
- Rating sentences for grammaticality
- Repetition of words and nonwords
- Circling letters on page of a text
Institutional Review Board (IRB)
A board that reviews all planned experiments to make sure they meet ethical standards following national guidelines
(Five) Examples of observations that cause us to wonder about language processing / observed difficulties associated with:
Proofreading
Garden path sentences
Irregularities in children’s speech that is unlike adult’s speech
Disfluencies related to word finding
Phenomena associated with communication disorders
Proofreading
- Correcting grammar, spelling, and punctuation
- How does top-down processing influence the ability to count how many f's are in a sentence?
garden path sentences
a sentence that is temporarily ambiguous or confusing because it contains a group of words that are compatible with more than one structural analysis
Examples:
I convinced her children are noisy.
I told the girl the cat scratched Bill would help her.
The man who hunts ducks out on weekends.
Irregularities in children’s speech that is unlike adult’s speech
Unlike adult speech
the boy goed home
I rided my bike
she telled me
I eated my grapes
she taked my toy
Disfluencies related to word finding
normal disfluencies when we are trying to retrieve a word
I wanted to paint the window….sill….using that great paint by….Valspar.
Phenomena associated with communication disorders
nonfluent aphasia - telegraphic speech - omission of functor words
nuisance variable
variables that could provide alternative explanations
independent variable
the thing you “wiggle” or vary systematically so that you can see its effects
dependent variable
what you measure to test your hypothesis
hypothesis
the carefully expressed, explicit version of the idea that the experiment is designed to test
stimulus
what we provide to experimental participants
response
how the participants react to the stimulus
Bousfield & Sedgewick (1944)
By having people list as many items in a category as they could in 10 minutes, they collected data to investigate the associative links between words and how activation may have spread.
2 Hypotheses from Bousfield & Sedgewick
category membership hypothesis
proximity hypothesis
category membership hypothesis
words have lemmas that are close to one another because of membership in the category DAIRY (in the example in class)
proximity hypothesis
referents close to one another in the grocery store
Sachs (1967)
Experimental Question:
What do we remember from sentences we hear- the message, the form, or both?
Sentences are only very briefly remembered in terms of form; very quickly what is remembered involves meaning
we store what we hear at Level 1: Message level and Level 2: Functional level
Bransford, Barclay, and Franks (1972)
Experimental Question:
Do we remember the actual meaning or mental pictures we construct when we hear something?
Results:
sentences that generate a new mental picture are easiest to detect, memory is most reliable at the message level
5 Spech Production Studies:
Oldfield & Wingfield
Belke et al.
Kohn et al.
Goldman-Eisler
Griffin & Bock
Oldfield & Wingfield (1965)
Task:
Picture naming of common and uncommon objects
Results:
the rarer a word is, the slower people were at naming a picture of it
Belke et al. (2005)
studied effects of category membership on latency of naming for words
Results:
Naming items in category 1 (clustered by semantic category) took longer than category 2 (across semantic categories)
when a category was "activated", naming was slower as if more choices had become activated and had to be rejected/suppressed before production of the target could occur
Kohn et al. (1987)
studied the tip of the tongue state
Methods:
18 participants were presented with definitions of words (varied in length and meaning categories) and were asked to give the word and to say what they were thinking as they tried to come up with it if the TOT state occurred
Results:
people who can't yet come up with the target can come up with some morphemes that could be in it or make up a word that could be a real one
Goldman-Eisler (1968)
Experimental Question:
What processes do people use to generate a sentence about a picture?
Results:
people hesitate more when they are asked to explain the cartoon than when they were asked to describe it
Griffin & Block (2000)
Task:
used eye tracking to observe where people looked while describing events shown in pictures of people interacting with animals, objects, or other people
Results:
people look at thing they're going to mention first, and they keep looking at it until its concept has activated the LEMMA. Then, they look to the next thing they’re going to activate
Warren (1970)
Comprehension Study
Task:
study design involved removal of a short part of an utterance (for example, the /s/ sound in the word legislatures
Results:
discovered the phonemic restoration effect, which is the tendency for our perceptual system to fill in missing speech sounds
Lexical Decision Task
Task:
decide as quickly as possible, whether a set of letters flashed on a screen (one-fifth of a second) makes a word or not
dialect
a variety of any language spoken by a group of people that is characterized by systematic differences from other varieties of the same language in terms of structural or lexical features
every person speaks a dialect of their native language
accent
systematic phonological variation (difference in pronunciation)
every person speaks in an accent
idiolect
form of a language spoken by one person
variation from speaker to speaker
slang
stylistic choices in vocabulary
jargon
technical language → speech production that just sounds like words in child development. Jargon is just technical language
“aphasia” is Jargon for speech path and audiology
register
speech style that is appropriate for a certain situation (example: formal versus informal)
mutual intelligibility
if speakers of one language variety can understand speakers of another language variety and vice versa
dialect continuum
large number of contiguous dialects on a continuum
5 types of language variation
phonemic
phonological
morphological
syntactic
lexical
phonetic variation
differences at the phonetic level that differ in its physical characteristics
phonological variation
inventory of sounds and how they’re distributed
caught versus cot
morphological variation
The distribution of morphemes
The use of completely different morphemes for the same function
SAE versus Appalachian English - past tense for certain verbs
climb, eat, and heat
morphological variation across registers
example: Spanish and other “pro-drop” languages you can drop pronouns from speech, which may depend on the context
yo hablo español vs. hablo español
syntactic variation
variation in the category in which certain words belong to
“she has already told you” verus “ she done already told you”
lexical / semantic variation
variation in the different words people use to mean the same thing
soda
pop
coke
Variation in what the same word means
British english versus american english
“knock up” - rouse from sleep by knocking versus to make pregnant
“to be pissed” - to be drunk versus to be mad
2 types of factors that influence variation
regional variation
regional and geographic factors that influence variation
social variation
social class, age, gender, ethnicity
Regional variation
languages are spoken in different geographical locations that are separate from each other
regional dialect boundaries often coincide with natural barriers
4 social factors
socioeconomic variation
age variation
gender variation
ethnic variation
socioeconomic variation
those in the higher SES typically define what becomes the “standard” dialect
associating with a particular SES can be expressed with language
age variation
younger speakers may not speak the same way as older speakers
rising intonation at the end of declarative sentences
use of “like” as an interjection
lexical variation - addition of new words (download) and loss of old words (dungarees)
gender variation
women are more likely to use standard variants than men
may be tied to social roles that women and men play
ethnic variation
nothing inherent about any ethnic group that causes members of the group to speak one way as opposed to another
people who belong to a particular ethnic group may not speak a dialect associated with that ethnicity
people who are not associated with a particular ethnicity may speak a dialect associated with it
When does language learning begin?
before birth in the 3rd trimester
Eimas et al. (1971)
Studies of speech perception in infants
rate of sucking on a pacifier to examine ability to distinguish differences between articulatory features (e.g., t/d)
most infants can determine what a person is looking at and look at it too by how many months?
5 months
children react different depending on whether an adult who isn't giving them a toy seems to be unable versus unwilling to give it at how many months?
6 months
children are learning to ignore phonetic differences not used in their languages by how many months?
10-12 months
McNeill (1966)
psycholinguistics of imitation
when anyone tries to imitate an utterance, what comes out is a varying mixture of what they’ve understood and what they have re-created from their own syntax, morphology, phonology, and phonetics
zone of proximal development
what your mind is ready to learn; it's neither too easy nor too difficult
5 types of early syntax
Whole phrase versus word combining
Plurals and past tense
Transitive verbs and sensory verbs
Prepositional phrases
Formulas versus constructions
Whole-phrase strategy
toddler doesn't seem to know that the syllables in the phrases are actually words with their own meanings
Word-combining strategy
Take two words they already know and combine them
shows that what's keeping children from combining words isn't conceptual but rather a limited word production skill
two-word stage
toddlers try to express a substantial range of semantic relations between people, things, and actions with two words
object-location, action-location, possession, agent-action, action-object
plurals and past tense
first reliably used bound morpheme is the progressive -ing
first free grammatical morphemes are in and on
next comes the regular noun plural ending (/-s/ and /-z/ forms)
then a few irregular past tense verbs
then other common morphemes
Berko (1958)
Do children memorize all the inflected forms that they know, or do they subconsciously learn rules for making plurals and past tenses?
Wug test
Wug Test Conclusions
children do learn the rules for putting the commonest endings on English words
When does early syntax development occur?
after 2 word stage
syntactic roles
the verb's subject and object
semantic roles
agent and undergoer
transitive verb
a verb that has an object, describes an action (ex: The ball hits the baby)
Sensory Verbs
class of verbs in which someone/something gets and experiences info about the world (ex; see, hear, feel, taste)
locative prepositional phrase
usually the first type of prepositional phrase learned by children; a locative modifier—a phrase that gives location information (ex: on the pillow)
Formulas
memorized utterance recipes that can be used to create an utterance, but not too much flexibility (ex: think of it like a recipe. Add one or two ingredients to customize it)
ex: Hi ______, ____ please, put ______ down
constructions
meaningful patterns of words that are more flexible
transitive verb clauses (the cat chased the mouse)
sensory verb clauses (Jimmy hears the doorbell)
locative prepositional phrases (The cat is on the pillow)
Hirsch-Pasek & Golinkoff
Research on how soon children begin to "de-construct" constructions in comprehension
used 2 screens to see children's understanding of transitive verb constructions (preferential looking study)
demonstrates that learning is a gradual process
canonical babbling
(6 to 10 months)
production of at least one well formed consonant in a syllable; sometimes as part of a sequence of repetitive syllables; bababa, dadada
Jargon
nonword, multisyllabic, intonation-rich productions
Protowords
specific recurring word-like or slightly longer utterances, "almost" words that are recognized by family members (ex: pacigo for pacifier)
phonological processes
patterns seen in child development that can be thought of simplifications that make talking easier
Fronting
"back" consonants (k, g) replaced by "front" consonants (t, d)
ex: dog--> dod
final consonant devoicing
final voiced consonants are produced as voiceless cognates
ex: dog--> dok, mud--> muk
Stopping
fricative consonants replaced by stop cognates
ex: that--> dat, zoo--> doo
Aphasia
an acquired language disorder caused by focal brain damage
How to talk to people with aphasia
1. unhurried fashion
2. use facial cues
3. use gestures and writing along with speaking
4. keep reflecting what you've heard
5. simple and direct communication
6. use normal volume
7. respect their intelligence
Focal damage
localized, covering a relatively small area
diffuse damage
widespread damage (Alzheimer's)
Broca's aphasia
- expressive/nonfluent aphasia
- understand the meaning of words quite well, but have a hard time figuring out the relationships among words
Wernicke's aphasia
- receptive or fluent aphasia
- have difficulty understanding the meaning of what they hear, but they apparently have some intact spreading activation processes and are able to complete syntactic processes such as those involved in the formation of long distance dependencies
telegraphic communication
includes omission of functors (articles, conjunctions) and tendency to use/overuse high-frequency words
sound errors
often occur on sounds that are also problematic to children (ex: fricatives)
2 Aphasic Assessments
Boston Naming Test
Western Aphasia Battery
Boston Naming test
- Assesses word retrieval abilities
- 60 black and white line drawings to name
Western Aphasia battery
- Determines the degree and type of aphasia
- Assesses:
content
fluency
auditory comprehension
repetition
naming
reading
writing
calculation
3 Aphasic Treatments
Melodic Intonation Therapy (MIT)
Semantic Feature Analysis
Constraint-Induced Aphasia Therapy (CIAT)
melodic intonation therapy
non-dominant hemisphere for language facilitates communication
phrase transformed into a melodic pattern of 3 or 4 tones
semantic feature analysis
semantic-level approach that aims to explicitly strengthen semantic representations
coached through specific semantic info that is relevant to a pictured object
encouraged to produce the lexical labels for characteristic semantic features associated with the target
Constraint-induced aphasia therapy (CIAT)
the goal is to overcome "learned nonuse"
3 principles:
massed practice (30 hours within 10 working days)
constraint induction/focusing on training (a range of techniques that allow the therapist to guide the patient towards forms of communication he or she might otherwise avoid)
behavioral relevance (mimic everyday communication, relevant complementary actions)
3 Hypotheses about syntactic processing deficits in aphasia
Global Parsing Failure hypothesis
The resource restriction hypothesis
The slowed syntax hypothesis
global parsing failure
hypothesizes that an individual with Broca's aphasia is incapable of discovering relationships between words in sentences when there are no semantic (meaning) cues to help them out
syntactic parsing
refers to how comprehenders use cues to determine how words in a sentence relate to one another during the process of interpreting a sentence
gap-filling syntactic processes
- ex: The people liked the waiter from the small town who served the drinks.
- includes a filler noun phrase (the waiter) that serves as a subject of the relative clause (who served the drinks)
- The sentence has long-distance dependency. The waiter is the subject of the verb served, but waiter is a long way away from served in the sentence
Zurif et al. (1993)
asked patients with Wernicke's aphasia and Broca's aphasia to process sentences with long-distance dependencies and react to probe words at critical points in the sentence
Results:
individuals with Broca’s Aphasia understand the meaning of words quite well, but have a hard time figuring out the relationships among words
individuals with wernicke’s aphasia have difficulty understanding the meaning of what they hear, but they apparently have some intact spreading activation processes and are able to complete syntactic processes, such as those involved in the formation of long-distance dependencies
resource restriction hypothesis
both building syntactic structure and assigning meaning to structured representations requires "resources"
brain damaged individuals suffer a reduction in resources
Possible support for this hypothesis:
Caplan and Hildebrandt (1988)
