The cognitive and linguistic reasoning process of the speaker’s choice of
modal expressions
Modality from the perspective of pragmatic impairment
The inability to use modality appropriately observed in
individuals with Autism Spectrum Disorder (ASD) is generally viewed as pragmatic
impairment. This
current study explores the divergent modal usage of ASD individuals, viewing
it as a pragmatic impairment to be examined from neurological, cognitive,
and linguistic perspectives. Based on statistical data derived from
observations of how ASD persons use modal expressions while speaking, this
paper clarifies the nature of their pragmatic impairment and proposes a new
model for
research. Although Systemic Functional Linguistics (SFL) did not explore the
cognitive side of language use, the current study supports the view that
pragmatic competency is primarily a neurocognitive and secondarily a
linguistic function. This is evidenced by the empirical studies of
lexicogrammatical choices made by individuals with cognitive disability such
as ASD, as the current study shows. The central issue is that seeing
pragmatic impairment from the neurocognitive perspective tells us
how various factors (in addition to language) are integrated when normal
people engage in conversational exchange in interpersonal situations.
