Analysis of the Descriptive properties
Is there a differential impact of the type of exposure to new lexical items that the children
receive on the provision of descriptive properties?
No significant differences were found for post test 1. Significant differences were found for
post test 2 (Kruskall-Wallis 1 Way-Anova: X2 = 31.2, df= 2 p<.0005) and post test 3 (X2 =
26.6, df= 4, p<.0000). During post test 2, “descriptive'' properties were used significantly
more by the Definition group than the Ostensive definition (Wilcoxon: Z = 4.1, p<.0005) and
the Lexical contrast group (Wilcoxon: Z =4.4, p<.0005). During post test 3, “descriptive"
properties were used significantly more by the Definition than the Control (Wilcoxon: Z=3.5,
p<.0005) the Phonological control group (Wilcoxon: Z=4.3, p<.0000) and the Ostensive
definition group (Wilcoxon: Z=3.5, p<.0005). In addition, descriptive properties were used
significantly more by the Lexical contrast than the Control (Wilcoxon: Z=3.5, p<.0005) and
Phonological control group (Wilcoxon: Z= 4.3, p<.0000).
