Lexical contrast and Definition group during post test 1 as well as for the Control and
Phonological control groups and the Ostensive definition group during post test 3.
Is children ,s performance on the naming task influenced by the semantic domain of the
lexical items ?
• All the children performed better if the target words described animals than artifacts.
The previous finding was true for the Lexical contrast and Definition group across
testing as well as for the Phonological control group during post test 3.
To what extent does the child’s prior lexical knowledge (Comprehension and Naming)
influence performance on the naming task ?
Baseline Naming Vocabulary
• All the children with high level naming vocabulary performed significantly better on
the naming task than children with low naming vocabulary across testing. The same
pattern was found for each group. Significant differences were found for the Lexical
contrast group and the Definition group during post test 2.
Baseline Comprehension Vocabulary
• Children with high level comprehension vocabulary performed better on the naming
task than those with low level comprehension vocabulary. Significant differences
were found for post test LThe same pattern was found for each group. Significant
differences were found for the Ostensive definition group during post test 3.
Concluding remarks for the naming task
► The above analysis of the naming task indicates that the Definition group performed
better than the Control, Phonological control and Ostensive definition groups. The
children performed better over time. They also performed better if they already
possessed a partial representation of the target word as well as if the target word
described animal than artifact. Last, children with high naming vocabulary performed
better than children with low naming vocabulary on the naming task.
