7.4.2.2.2 Definition task
Scoring criteria for the definition task
Each child had to answer four questions. To be scored correct, the response had to be
provision of an appropriate definition, and incorrect the provision of an incorrect definition.
For the present experiment appropriate definitions were those which included correct
information about the meaning of the target words. Thus, definitions which included any
correct perceptual and/or semantic an∕or functional and/or contextual information about the
target words were considered as appropriate. Each child could get a score from 0-4.
Analysis
Figure 7.7 demonstrates how the different groups performed on the definition task across
testing. Their performance varies across testing as well as by the type of exposure mainly
after post test 2.

Is there a differential impact of the type of exposure to new lexical items that the children
receive on the provision of definitions?
The above figure shows that the Definition group performed better that the other groups
across testing. The differences were significant for post test 2 (Kruskal-Wallis, X2 =38.3,
df=2, p<.0000) and post test 3 (Kruskal-Wallis, X2 =37.3, df=4, p<.0000).
