Lj. Garcia et al., Relevance is in the eye and ear of the beholder: An example from populations with a neurological impairment, APHASIOLOGY, 15(1), 2001, pp. 17-38
Describing problems of relevance in clinical populations has been a subject
of interest for both theoreticians and clinicians. The argument that conve
rsational relevance is a product of listener interpretation is supported in
the present paper. Study 1 examines the topic-shifting profiles of a socia
l worker in conversation with normal elderly participants as compared to he
r profiles in conversation with participants with dementia. Study 2 compare
s semantic segments in conversations between this same social worker and a
normal adult and a traumatically brain-injured adult. Qualitative differenc
es were found in Study 1 in the types of topic shifts used, the possible re
asons for these shifts, and the context to which the shifts related. In Stu
dy 2, differences were found in the types of relationships between semantic
segments and in the relative proportion of implicit and explicit segments.
Support is given for considering conversational partners' roles in determi
ning relevance.
