7.4.2.2.6 Story generation Task

Scoring criteria for the story generation task

Responses were scored as correct and incorrect. Provision of an appropriate story was scored
as correct, while failure to provide an appropriate story scored as incorrect. For the purposes
of the present experiment, appropriate stories were operationally defined as the stories which
included elements which gave information about the word’s meaning. Stories which included
descriptive, semantic, functional and contextual properties about the target words were
appropriate. Each child could get a score from 0-4. Qualitative analysis of the stories was
also carried out.

Analysis

The children found the task difficult, since the provision of appropriate stories was overall
quite low (Pl=I 8.9%, P2=24%, P3=24%). The inter-rater reliability for coding the stories as
appropriate reached the 97% of agreement. The following figure shows that the Definition
group provided more stories than the other groups across testing.

Is there a differential impact of the type of exposure to new lexical items that the children
receive on the provision of stories?

No significant differences were found for post test 1, while significant differences were found
for post test 2 (Kruskall-Wallis-I Way Anova:X² = 16.1, df = 2, p<.005) and post test 3
