Does children ,s provision of descriptive properties increase -with increased exposure to the
lexical items?
The number cd “descriptive” properties provided during post test 3 was significantly higher
than in post test 1 (Wilcoxon: Z= 5.4, p<.0000) and post test 2 (Wilcoxon: Z=4.8, p<.0000).
Separate analysis for each group revealed that the Ostensive definition group provided
significantly more “descriptive” properties in post test 3 than in post test 2 (Wilcoxon:
Z=3.00, p<.005). The Lexical contrast group provided significantly more “descriptive”
properties in post test 3 than in post test 1 (Wilcoxon: Z=3.9, p<.0005) and post test 2
(Wilcoxon: Z=4.1, p<.0000). The Definition group during post test 2 provided significantly
less “descriptive” properties in post test 1 than in post test 2 (Wilcoxon: Z=3.2, p<.005) and
post test 3 (Wilcoxon: Z=3.7, p<.0005).
Does the children ,s prior knowledge of the lexical items influence the provision of descriptive
properties?
All the children provided more “descriptive” properties for the partially represented than for
the unknown words. Significant differences were found for post test 2 (Wilcoxon: Z=2.3,
p<.05). Separate analysis for each group revealed the same pattern. Significant differences
were found for the Definition group during post test 2 (Wilcoxon: Z= 2.04, p<.05) and post
test 3 (Wilcoxon: Z=2.03, p<.05).
Is the provision of descriptive properties influenced by the semantic domain of the lexical
items?
The children provided significantly more “descriptive” properties for the words describing
animals than for the words describing artifacts across testing (Wilcoxon, Pl: Z=3.2, p<.005;
P2: Z=2.4, p<.05; P3: Z=2.5, p<.05). Separate analysis for each group demonstrated the same
pattern. Significant differences were found for the Ostensive definition group during post
test 1 (Wilcoxon: Z=2.02, p<.05), the Lexical contrast group during post test 3 (Wilcoxon:
Z=2.02, p<.05) and the Definition group across testing (Wilcoxon, Pl: Z=2.02, p<.05; P2:
Z=2.8, p<.005; P3: Z=2.5, p<.05).
