Midterm 1 Flashcards
Speech Language Pathologists vs Audiologists
SLPs diagnose speech language problems, and work with people that may have receptive, expressive, or pragmatic difficulties
Audiologists specialize in issues related to hearing impaired hearing lost, hearing aid assistance, etc.
When are Communication Difficulties developed
Can start from birth, or can be developmental or acquired
Receptive Language
Understanding and comprehending language
“The Input” I.e. a child’s ability to listen and follow directions
Expressive Language
The production of language
(speaking, gesturing, writing, facial expressions, and vocalizations)
Pragmatic Language
The social context of language
I.e. it’s hot so you ask someone to open the window
Language Modalities
Visual Gestural: signed languages, perceived visually
Tactile-gestural: perceived via touch, gestures are intended to be felt, not seen
Auditory-vocal: spoken
Linguistic Flexibility
Language is creative so grammar can be debated
Descriptive Grammar
Describes what happens in a spoken language and accepts the pattern differences people use without judgement
I.e. some English speaks use double negatives for negation
The Three Types of Grammar
Mental: what is implicitly known about a language’s structure and systematicity
Descriptive: what a linguist observes are a language’s structure and rules, what happens in a spoken language
Prescriptive: socially embedded notion for “correct” ways to use language
Hockett’s design features of language
Mode of communication, semanticity, pragmatic function (all communication system needs these)
interchangeability, cultural transmission, arbitrariness, discreetness
Displacement and productivity (unique to human language)
Speech Teachers
People who help individuals with problems like stuttering, articulation disorders, language delay, etc.
Semanticity
Principle that all the signals/symbols in a communication system convey a meaning or function
Pragmatic Function
Language serves a purpose and it doesn’t need to be profound
I.e. chit-chat
Interchangeability
Individuals ability to transmit and receive messages
Cultural Transmission
Principle that we acquire language through interacting with other users of that system
Arbitrariness
Words are not predictable and don‘t dictate meaning
I.e. “Bank” could mean two different things
Discreteness
Idea language is comprised of categorical units that can be combined in different ways
Displacement
Ability to talk about things, actions, ideas, and people whom we are physically or spatially separated
I.e. talking about Julian to Steph when we’re in Van and he’s in Calgary
The Three Kinds of Language
Formal: computer languages and mathematical proofs
Natural: those that evolve naturally in a speech community
Constructed: specifically invented, can become natural if they are learned as a first language and are used by a speech community
Evidence Based Practice (EBP)
Central concept that any treatment should be supported by scientifically based evidence in it’s effectiveness
Outcome measures should have the best possible face validity
Efficacy
Referring to the effectiveness of a therapy procedure
Three Types of Research
Basic: research questions and activities that improve basic knowledge (foundational)
Applied: research questions/activities that have more immediate consequences, applying findings to improve something
Clinical: applied research on clinical populations
Outcome Measures
How to determine whether a treatment or invention works and if it has good face validity
Levels of Evidence: VI
Weakest level: a well informed expert says something is true
Level of Evidence: V
Second weakest: Case reports and or literature reviews
Gives no control or comparison group, small sample size and can’t be generalized
Levels of Evidence: IV
Third weakest: Research studies/treatments lacking a control or comparison group
A lack of controls means that any treatment could have improved the person or group, not just the one used
Levels of Evidence: III
Third Strongest: experimental study that is not randomized, has a comparison or control group, very common in the field
Levels of Evidence: II
Second best: one randomized control trial—a well designed experiment with the random sampling
Hard to in the field and almost never done because individuals come from such diverse backgrounds that it’s hard to match them
Levels of Evidence: I
The strongest: meta-analysis or systematic review from many RCTs (Randomized control trial)
Hard to obtain
What is language
Socially (shared with others in a community) learned and conventionalized (arbitrary and agreed upon) symbolic system
Language Variation
Idea there is nothing inherently correct about one way of speaking—no language is better or worse than another
Accent
How a person’s sound of speech and the melody and rhythm of their speech differs
Dialect
A language variant typically associated with a geographical region or group of people
May include accent but also may include unique vocab, grammar and rules
Examples of cultural factors that can influence communication
Race, ethnicity, social class, education, occupation, geographical region, gender, sexual orientation, situation, context
Age-Normed standardized test
Data is used to compare a child’s language performance with the goal of having an accurate estimate of the age when typically developing children master a particular linguistic dimension or element
Cultural Competence
Necessary recognition of a difference as a difference and not a delay or impairment
Sometimes cultural biases can cause SLPs to diagnose children with a language delay
Code Switching
Essentially switching between languages or dialects, often for the words more common in the respective language
I.e. Broken Chinese
Simultaneous bi/multilinguals
Someone who has roughly equal exposure to multiple languages and cultures at age 2 or younger
Sequential Bilinguals
Individual who learns one language from birth, and an additional language at an early age (3-4 years old)
Late Learning Bilinguals
Individual who learns one language from birth and another at a later age (adolescence or adulthood)
Accent Modification
An SLP provided service typically seeking to reduce one’s foreign accent
Controversial because it is presented as homogenizing an individuals identity
Phonetics
The small units that comprise words (sounds and signs)
I.e. sip vs zip (Changes meaning)
I.e. Toronto vs torono
Articulatory Phonetics
The ways which your articulates move and coordinate actions, studied through ultrasound and palatography
Acoustic Phonetics
Physical Manifestation of speech sounds, studied through spectrograms
Auditory Phonetics
The human response to stimuli
Phonotactic Constraints
Restrictions on possible sound combinations and what sounds can occur together in certain positions
I.e. Nguyen in English doesn’t really have a clear pronunciation
I.e English doesn’t allow two stops or a stop and nasal combination at the beginning of words—gnostic=drop the first consonant
Phonetic Transcription
Goal of being able to write down a language such that any one who knows the alphabet can read and produce the appropriate sound
Each symbol represents one phone (sound) and if sounds are different they need different symbols
Also states that if two sounds are within a certain similarity but differed from context, the same symbol should be used
(English often fails this)
