COMDIS415 ASD + ARTICULATION Flashcards
General characteristics of ASD
Social Interaction
Communication
Restrictive, repetitive behaviors
Range of cognitive ability in ASD
Hyposensitivity: underreaction to one’s sensory environment
Hypersensitivity: overreaction to one’s sensory environment, bright lights may bother them and little sounds may annoy them
Symptoms are recognized in the first 2 years of life
BEHAVIORAL
Perseverance : Really focused on one activity or object and it’s really difficult to break the thought or fixation
Narrow range of interests: cars, history, astronomy for example
Perseveration on objects and topics
Repetitive stereotypic body movements: rocking, jumping, twirling, rearranging objects
Dependence on routine
hard to break regular routine and when they do, they take it very hard, INFLEXIBILITY IN MODIFYING AND RESISTANT TO UNEXPECTED CHANGES
Sensory symptoms
hyper or hypo sensitivity
SOCIAL CHARACTERISTICS
Infrequently engage and disinterested in social interactions (this includes starting and continuing conversations)
Difficulty understanding other people’s perspectives (lacking empathy)
Difficulty providing or seeking comfort
COMMUNICATION DISORDER
Lack of joint attention and initiating it; difficulty following attention of others, commenting and requesting
Pragmatics are impaired (may say things at the wrong time/wrong place, inappropriate language
Verbal responses can appear rigid, ritualistic, and stereotypical
Difficulty interpreting and using facial expressions, gestures, and body language
RECEPTIVE LANGUAGE IS MORE IMPAIRED THAN EXPRESSIVE; they have trouble picking up on social cues
What is echolalia - identify the two forms of echolalia
Immediate, or Delayed
Immediate Ecolalia
Within 2 conversational turns of original language input
Delayed Ecolalia
After more than 2 conversational turns take place, they repeat something you said a month, week, or days ago: can represent a significant memory, emotion, or area of interest
What is Ecolalia?
A form of vocal repetition
ONE OF THE MOST COMMON CHARACTERISTICS OF COMMUNICATION IN PEOPLE WITH ASD
What is Ecolalia? 2
A group of words can have a single meaning
Come sit down at the table might mean table
Echolalia can be a single words or group of words
What type of behavior is ecolalia?
It is a verbal behavior
Could be a repetition of self, others, television, radio, song etc but it will also be verbal
Serves a variety of purposes
Requesting
Express stress/anxiety
What are the general language characteristics?
Similar pattern of sound acquisition but may have speech errors as adults
Delayed morphology and syntax but typical just delayed
Depth of word knowledge (vocabulary skills) may be affected
Impaired voice and prosody
Difficulty controlling volume
Awkward stress, intonation, and rhythm patterns
Disfluencies
Differences in phrasing
Echolalia
A short term goal for ASD
Working on pragmatics and understanding what is appropriate and what isn’t; working on initiating and maintaining conversation
What are the prelinguistic red flags?
Neutral affect
Limited joint attention
Fewer social interactions
Limited response to name
Poor eye contact
Lack of pointing
Delays in play
Characteristics of speech sound disorders
Low score on norm-referenced test
Arises from a high numbers of errors on phonemes
Number of errors are higher than what is expected for age
Errors significantly limit intelligibility
How much of a child’s speech should be intelligible?
2-year-olds – 50% intelligible
3-year-olds – 75% intelligible
4-year-olds – 100% intelligible
Phonetic
Motor act of producing sounds or articulation (Substitution, Omission, Distortion, Adding)
Phonological
Cognitive-Linguistic level that organizes speech sounds into acceptable patterns within the language or phonology
Responsible for creating sounds distinct from one another so they can differentiate in meaning
E.g /paet/ vs /baet/
Two problems simultaneously
Articulation
Inability to completely articulate certain speech sounds (difficulty at phonetic level)
Motoric production of speech sounds
Phonology
Predictable rule-based errors that affect more than one sound (difficulty at phonemic level)
Phonological Processes Examples
- Cluster Reduction
- Stopping
- Fronting
- Glide
- Deletion
- Deaffrication
