and 7.12).

7.4.3.7 Comparing children’s performance across the post test measurements
Children’s performance across the seven post test measurements was compared. The
responses that were counted as correct for each task are the following:

(a) Naming task: accurate naming of the target words

(b) Multiple choice task: accurate pointing of the target words

(c ) Association task: provision of perceptual, semantic and thematic justifications

(d) Contrast task: provision of semantic contrasts for the target words

(e) Story task: provision of appropriate stories for the target words

(f) Definition task: provision of appropriate definitions

(g) Short questions: provision of accurate choice patterns for the target words.

Figure 7.37 below shows children’s performance across the different post test measurements.
As the figure shows children’s performance varied by type of measurement across testing.
Children performed better on the multiple choice, short questions (world knowledge
questions), association and definition tasks than the naming, contrast, story generation and
short questions (categorisation questions) tasks.
