Midterm 1 Flashcards
What is Evidence Based Practice? (EBP)
Any practice that has been established as effective through scientific research following specific criteria
Criteria for EBP in Special Education
- Accountability 2. Scientifically based instruction 3. Highly qulified teachers
What is the prevalence of ASD?
1/88
-Due to the rise in the number of children diagnosed -ASD is the fastest-growing special education eligibility category
reasons we need more competent service providers
Issues with EBP include
- personnel preparation 2. lack of university level special education and clinical preparation programs specializing in ASD 3. school districts develop their own training, hiring outside contractors, didn’t have experts in this field teaching content.
ASD is the _____ growing _____education eligibility category
fastest, special
The National Research Council (NRC) conducted a comprehensive review of the scientific base for educating children with ASD, highlighting what?
1.The need for further research 2.The roles of families 3.Characteristics of effective programs 4.Preparation of educational personnel
numbers in ASD have
risen significantly over the years
1.Individualized supports and services 2.Systematic, carefully-planned instruction 3.Comprehensible and structured learning environments 4.Specialized curricula focused on core challenges (social/communication) 5.Functional approach to problem behavior 6.Family involvement
positive contributions of EBP Developed strategies and approaches for effective practice for students with ASD
Elementary and secondary act
requires states to ensure that educators at the elementary and secondary levels are capable of: 1. accountability-applying standards and assessments, collect meaningful data 2. scientifically based instruction-using ebp that applies rigorous, systematic & objective procedures to obtain knowledge 3. highly qualified teachers-competent in design & delivery of effective ed programs, understand & apply core elements of effective ed practice aka no child left behind (nclb)
Personnel Preparation Issues
-Lack of university-level special education and clinical preparation programs that include a specialization in ASD -Large influx of students with ASD into the system, so schools have faced shortages of competent educators and related service providers -Personnel preparation is one of the weakest elements of effective programming for children with ASD and their families
a decline in eye fixation takes place for children with ASD which is not noted in infants who did not develop autism (
at 2-6 months of age
subtle differences in sensory-motor and social behavior (Baranek, 1999) as well as differences in the use of communicative gestures
at 9-12 months of age
children with ASD exhibit fewer joint attention and communication behaviors when compared to TD same-age peers (and they exhibit atypical eye contact, passivity, decreased activity level, and delayed language
at 1 year
abnormalities in children’s language development and social relatedness are noted
at 14 months of age
can be diagnosed in
the first two years of life average 4-5
(No Child Left Behind Act) requires states to ensure that educators at the elementary and secondary school levels:
demonstrate accountability, provide scientifically based instruction, and are highly qualified.
the difficulty of putting oneself in another’s shoes.
mind blindness or TOM
he ability to recognize and understand the thoughts, beliefs, desires and intentions of other people in order to make sense of behavior and predict what they are going to do next.
TOM
executive functions
organization and planning, working memory, inhibition and impulse control, time management and prioritizing, using new strategies, thoughtful deliberation prior to speaking. people with ASD have been recognized as having problems with executive functions
DSM 5 criteria for ASD
Stricter criteria than DSM IV meaning fewer ASD diagnoses Pervasive development disorder (DSM IV) has changed to autism spectrum disorder inclusion of hyper- and hypo- reactivity to sensory input or unusual interest in sensory aspects of the environment (Example of restricted, repetitive patterns of behavior, interests, or activities)
refrigerator mothers
Some doctors tried to say autism was caused by the lack of warmth from moms of autistic children” (good way to remember is refrigerators are cold- therefore ‘cold’ personalities from mothers)
echolalia
immediately echoing the utterance of someone i.e. repeated verbatim sentences from a tv show
non-verbal behaviors
Deliberate behaviors other than speech/vocalizing (gestures) People with ASD have difficulty with nonverbal communication includes eye gaze, body language, proximity, gestures
DSM-IV dimensions
DSM-IV dimensions: Impairments in social interaction Impairments in communication Restricted/repetitive behavior
DSM-V dimensions
Deficits in social communication (combined DSM-IV 1 & 2) Restricted/repetitive behavior DSM criteria now includes hyper and hypo reactivity to sensory input or unusual interest in sensory aspects of the environment
early onset
Symptoms must be present in the early developmental period (prior to one year) May not become fully manifest until social demands exceed limited capacities, or may be masked by learned strategies later in life. Early onset feeding problems, sleep disturbance are also present
early warning signs
those discussed before, 2-6, 9-12, 1 etc
late onset
Occurs after the second year. Children achieve developmental milestones in motor, linguistic, and cognitive skills. Demonstrate a reasonable spoken vocabulary. Develop early symbolic and imaginative play. Sudden regression in speech, vocab (peaks at 18 months). Similar to a child with early onset ASD at 3 years
possible contributing factors to ASD
Genetics, Neurology, Errors of Metabolism, Gender Differences Family history of autoimmune disorders , type 1 diabetes, asthma, especially in mothers of children with ASD Infections during pregnancy and early child. (herpesvirus, post measles)
Neurological differences between ASD and typically developing children
Children with ASD have dysfunctions with serotonin and dopamine. reduced neuron size and density Large brain volumes on the MRI; increased cerebellar and cerebral cortex white matter, increased grey matter. *amygdala is affected - important for memory and social/emotional functioning
First signs of ASD warning signs
poor eye contact, lacks gestures -pointing, reaching, waving; doesn’t understand simple questions or directions. speaks in abnormal tone. repeats same actions over and over and over again.
other signs of asd
sleep disturbance and feeding problems difficulty comforting the child child may not be drawn towards social activities & prefer to play alone child appears not to consider people as the most important aspects of daily life, preferring instead to explore and play with objects and enjoy sensory experiences content with long periods of solitude delay in speech
central coherence, gestalt
Strengths in things like details, but weak when it comes to putting those details together into one concept. Having a weak central coherence in Poor Common Sense for example would be the child takes things literally, difficulty reading context, and doesn’t quite get it! doesn’t see the big picture. Problems with seeing this ‘big picture’ would be the child; focus’ on all the details instead, difficulty seeing invisible relationships
fMRI studies
studies revealed that differences in brain have structural and functional abnormalities abnormalities originate within the genetic code that controls what will happen later in brain development Behavioral differences in those with ASD result from an underlying biological difference.
fMRI studies
Suggests there is not the same degree of connectivity in individuals with ASD (that’s what my notes say, but I have more @ home that I know make better sense) fMRI has become the first true window on the thinking brain in autism! (pg 64) fMRI monitors the brain during the performance of cognitive/language tasks. reveals that the brain is organized the same but had different connectivity studies showed that people with ASD had brain regions that were not working together to support language function
without supports in place, deficits in verbal and nonverbal social communication cause noticeable impairments, difficulty initiating social interactions, inflexibility of behavior causes significant interference with functioning in one or more contexts, difficulty switching between activities, problems of organization and planning hamper independence.
