In spite of current interest in conversational disability, and the gro
wing number of children who are being diagnosed as exhibiting this dis
order, there are few satisfactory procedures that can be used to asses
s their conversation. In the following paper, data from the naturally
occurring conversations of two children, who were identified as having
difficulties in participating in conversation, are presented. The dat
a were scanned for the following conversational skills: securing the a
ttention of the addressee before speaking, initiating new topics of co
nversation effectively, using the grammatical forms that are most freq
uently associated with particular linguistic functions, filling respon
se slots effectively, maintaining cohesion within the discourse, and t
aking steps to repair mishearings or misunderstandings. This kind of a
ssessment, based on the principles of conversational analysis, provide
d an objective appraisal of the conversational skills of the children,
and also highlighted potential areas for therapeutic intervention. Ma
ny of the conversational behaviours exhibited by the two subjects corr
esponded with those that have been observed in very young children who
are developing language normally. It is suggested that the subjects s
tudied here presented with a severe delay in their conversational deve
lopment rather than a disorder.
