**Research using neuroimaging techniques such as CAT scans, MRIs, and PET scans suggest that some cases of learning disability are caused by ______?
Structural and functional differences in the brain
**Individuals who have a cluster of exceptionalities in social interaction, math, visual-spatial tasks, and tactual tasks are referred to as having ____?
nonverbal learning disabilities
What are learning disabilities?
LDs are neurological disorders that interfere with one’s ability to store/understand/communicate information
What do interventions for LDs target?
Interventions target specific subtypes of LDs. They look at accommodations, learning strategies and self-advocacy.
What can LDs impair?
Abilities to: read, write, spell, reason, compute math, attention, coordination, memory, social skills
What does SLD stand for and what do they include?
Specific Learning Disabilities. Can include: dyslexia, dyscalculia, dysgraphia, auditory processing disorder, language processing disorder, non-verbal LDs
How do physicians determine the presence of an LD?
Physicians use developmental, family and education history. They focus on how general academic performance can be improved.
Describe the Achievement-Ability discrepancy.
IQ scores of an individual are higher than their academic performance suggests.
What are some of the issues with identifying LDs with IQ tests?
In the RTI model, what does Tier 1 consist of?
In the RTI model, what does Tier 2 consist of?
In the RTI model, what does the multidisciplinary team do?
- an IEP is developed
In the RTI model, what does Tier 3 consist of?
What are some of the cautions regarding the RTI model?
Approximately how many students in Canada (age 8-11) have LD’s?
~ 4%
Is the prevalence of LDs higher in boys or in girls?
Boys, 3:1
What are some of the causes of LDs?
1) CNS dysfunction
2) genetic factors
3) toxins (lead, air/water pollution)
4) medical factors (premature birth)
Define inter-individual/heterogeneity variation of learning disabilities.
Reflected in the broad range of problem areas that are identified as LDs (reading, math, attention, etc). What classifies as a LD changes from child to child.
Define intra-individual variation of LDs.
Even within one child, there is a lot of variation in what they need and how their LD presents itself.
What is the defining feature of LDs?
Academic deficits
Define prosody in the context of reading aloud.
The ability to make your oral reading sound like spoken language, using appropriate intonation and expression.
Define dysgraphia.
Problems with handwriting, spelling and/or composition
Define issues with spoken languages that can be present in LDs
Problems with the mechanical and social uses of language (syntax, morphology, semantics, phonology, pragmatics)
Define dyscalculia.
Difficulties with computation of math facts as well as word problems. This may be associated with processing deficits in working memory and retrieval.
