Answer 9

convert raw score to standardised

Question 10

Which assessment approach best captures developmental functioning in naturalistic settings?

Answer 10

Adaptive behaviour questionnaires

Question 11

A researcher argues that defining atypical development purely on the basis of statistical deviation is problematic. Which example best supports this claim?

Answer 11

Many children score below average on at least one measure

Question 12

A school psychologist is interpreting WISC scores for a bilingual child. Which consideration is most important to avoid misclassification?

Answer 12

Interpreting scores without reference to language exposure

Question 13

Answer 13

The arbitrariness of diagnostic thresholds

Question 14

When psychologists compare a child’s performance to same-age peers rather than older or younger children, they are relying on which feature of standardisation?

Answer 14

Norm-referenced scoring

Question 15

The findings from WISC-V profiles in children with ASD most strongly challenge which assumption about atypical development?

Answer 15

That overall IQ reliably captures developmental strengths and difficulties
