Question 1

A student scores significantly higher on a test of reading fluency than on a test of reading comprehension. Which diagnostic hypothesis best explains this pattern?

Accepted Answer

Hyperlexia or language comprehension deficit

Answer

Strong decoding with weak comprehension is characteristic of hyperlexia or a language comprehension disorder, where word recognition is intact but meaning extraction is impaired.

Question 2

When interpreting a Cattell-Horn-Carroll (CHC) profile, a diagnostician notices low scores in Gs (processing speed) and Gsm (short-term memory) with average scores in Gf and Gc. This pattern most likely impacts:

Accepted Answer

Timed tasks and multi-step instruction following

Answer

Deficits in processing speed (Gs) and short-term memory (Gsm) directly affect performance on timed tasks and the ability to hold and execute multi-step instructions.

Question 3

A diagnostician is evaluating a student who shows scatter across subtests of a cognitive battery with no clear pattern. The most appropriate next step is to:

Accepted Answer

Examine behavioral observations and consider supplemental testing to clarify the profile

Answer

Subtest scatter warrants careful clinical interpretation, review of behavioral observations, and supplemental assessment rather than averaging or premature diagnosis.

Question 4

Which error analysis technique is most useful for distinguishing a phonological deficit from an orthographic deficit in a student with poor spelling?

Accepted Answer

Analyzing whether errors are phonetically plausible or violate sound-symbol correspondence

Answer

Phonetically plausible errors (e.g., 'bote' for 'boat') suggest orthographic knowledge gaps, while phonologically implausible errors point to phonological processing deficits.

Question 5

A bilingual student's scores on a norm-referenced English language test fall in the below-average range. The MOST critical step before interpreting this as a learning disability is to:

Accepted Answer

Evaluate language proficiency and performance in the student's primary language

Answer

Determining whether low scores reflect limited English proficiency versus an intrinsic processing disorder requires assessing skills in the student's dominant language.
