Is performance on the multiple choice task influenced by the semantic domain of the lexical
items?
There was a maximum group score of 260. Figure 7.6 demonstrates that children’s
performance on the multiple choice task was at the same level for both types of words
(animals and artifacts). No significant differences were found.

The analysis was repeated separately for each group. It was found that during post test 3, the
Ostensive definition group performed significantly better on the multiple choice task when
the target words described artifacts than animals (Wilcoxon, Z=2.02, p<.05).
