An independent samples t-test shows that on
the PEPS-C test there is no significant difference
between the children with AS and the typically developing children in all
but one of the prosody tasks. The graph below shows that this was the Prosody
Output task (shown on the graph as the yellow star), and that scores were
all significantly lower (p=0.018) for children with AS than for children with
typical development. Green highlighting shows a mean score of 75 or more and
indicates competence, while red highlighting shows a mean score of under 75,
which indicates that the group had difficulty with the task.
AS mean= 13.736, TD mean=14.714
Results from the PEPS-C test also showed that
children with HFA have a prosodic impairment whereas children with AS perform
in line with typical children. The graph below shows tasks where children
with HFA performed significantly lower than children with AS and children
with typical development (shown in yellow).
- In general, the children with Asperger’s Syndrome showed skills equal to children with typical development
- Children with Asperger's Syndrome had difficulty with the Prosody Output task.
- Children with Autism scored significantly lower than children with Asperger's Syndrome in the Affect tasks, Prosody tasks, Intonation Input, and Focus Output tasks.
