Is the provision of contrasts influenced by the semantic domain of the lexical items?
• No significant differences were found in the provision of contrasts by the semantic
domain of the lexical items.
To what extent does the child’s prior lexical knowledge (Comprehension and Naming)
influence the provision of animal contrasts in the contrast task!
Baseline Comprehension Vocabulary
• The provision of contrasts did not differ significantly by their baseline
comprehension vocabulary.
Baseline Naming Vocabulary
• Children with high naming vocabulary provided more contrasts than children with
low baseline naming vocabulary across testing. Significant differences were found
for post tests 2 and 3. Separate analysis for each group demonstrated the same
pattern. Significant differences were found for the Lexical contrast group in post test
2.
Types of contrasts
• Children provided animal, cutlery, furniture and other contrasts. They provided
significantly more animal contrasts for the ostrich and the mole than the other words,
more cutlery contrasts for the ladle than the others and more furniture contrasts for
the stool than the rest of the target words across testing.
Animal contrasts
Is there a differential impact of the type of exposure to new lexical items that the children
receive to the provision of animal contrasts?
• The provision of animal contrasts did not differ significantly by group (Diagram 7.9).
Does children ,s provision of animal contrasts increase with increased exposure to the lexical
items ?
• No significant differences were found over time.
