Q

What are common drawbacks to each approach for identifying SLD

A
  1. There will be false positives and false negatives
  2. Closer to threshold, the more info you will need to support a learning strength or weakness.

Q

What is the conceptual understanding of the PSW procedure?

A

Cognitive strength is DISCREPANT with a cognitive weakness.

Q

Does SLD include individuals with lower academics and lower IQ (71 to 84)?

A

No - the “S” (specific) argues against this - it is not a global learning issue (slow learner).

Q

What is another flaw of RTI?

A

Only identifies achievement differences and a valid SLD classification requires achievement and ability information.

A

Associative Memory (MA), and Meaningful Memory (MM).

27
Q

What does Retrieval Fluency (Gr) measure?

A

The rate and fluency at which individuals can access information stored in long-term memory.

28
Q

What does Learning Efficiency (Gl) measure?

A

The ability to learn, store, and consolidate new information over periods of time (minutes, hours, days, years).

29
Q

What are the narrow abilities for Retrieval Fluency (Gr)?

A

Speed of lexical access - intermediate stratum (LA), Naming Facility (NA), Word Fluency (FW), Ideational Fluency (FI), Expressional Fluency (FE).

30
Q

What are the narrow abilities comprised in Working Memory capacity (Gwm)?

A

Auditory Short Term Storage (Wa), Visual-Spatial Short-Term Storage (Wv), Attentional Control (AC).

31
Q

What is the broad ability of Working Memory Capacity (Gwm) referred to?

A

Working Memory

32
Q

What are the 4 narrow abilities under Working Memory (Gwm)?

Q

What are the AC classification rules?

A

If AC is a secondary classification for Gwm. AC is inherent. If AC is an appropriate classification for atask outside of Gwm, AC should be the sole classification.
