School Neuropsychology - dual discrepancy/CHC Flashcards
Study materials
What are the 3 options for identifying SLD
- Ability-Achievement Discrepancy (AAD)
- Response to intervention (RTI)
- Alternative research-based procedures (e.g., PSW)
Currently, what is the percentage of each of the three identification processes being used by school psychs?
Each method is being used by 1/3 of psychs.
What are common drawbacks to each approach for identifying SLD
- There will be false positives and false negatives
- Closer to threshold, the more info you will need to support a learning strength or weakness.
How are the RTI and Ability-Achievement options alike?
Circular logic
What is the conceptual understanding of the PSW procedure?
Cognitive strength is DISCREPANT with a cognitive weakness.
Cognitive weakness is CONSISTENT with an academic deficit.
Academic weakness is DISCREPANT with a cognitive strength
4 levels of assessment to meet SLD requirement
What is a critical flaw in PSW currently?
Criteria vary across methods and lack agreement and consistency.
What is the conceptual understanding of the DD/C model?
Cognitive strengths DISCREPANT with academic weaknesses
Cognitive weaknesses and DISCREPANT with Cognitive strengths
Cognitive weaknesses are CONSISTENT with academic weaknesses
Does SLD include individuals with lower academics and lower IQ (71 to 84)?
No - the “S” (specific) argues against this - it is not a global learning issue (slow learner).
What is another flaw of RTI?
Only identifies achievement differences and a valid SLD classification requires achievement and ability information.
What is cross-battery assessment (XBA)?
Involves measurement of theoretical ability constructs - introduced in 1997
What is the DD/C (dual discrepancy/consistency) model?
It involves the analysis of test results to determine if they meet the DD/C criteria to support an SLD diagnosis - introduced in 2002.
How many PSW methods are there?
5 - each has slightly different criteria (70% of SP programs teach the PSW model)
GLR is now split into what two areas?
Learning Efficiency (Gl) and Retrieval Fluency (Gr)
What does a domain-specific weakness mean?
The weakness is concentrated in a specific area(s) and not global or general.
What does unexpected underachievement mean?
That despite good reasoning/cognitive abilities there are learning deficits.
What is a great intervention for slow learners (learners who have global delays)
RTI - it provides small group intervention.
What is inductive reasoning
Specific to broad/general, Bottom-up approach
What is deductive reasoning
Moves from general to specific. Top-down approach. Starts at a general statement to reach a logical conclusion.
How many broad abilities are in the current CHC theory?
There are 17 broad abilities.
How many narrow abilities are there in the current CHC model?
There are 80 narrow abilities.
What are the Fluid (Gf) reasoning narrow abilities?
Induction (I), General Sequential Reasoning (RG), Quantitative Reasoning (RQ)
What are some tests that measure Gf?
Matrix Reasoning, Figure Weights (WISC)
Number Sense/Concept Formation (WJ)
