This is what I will do for the first year of my stay here in Groningen
Comprehension and Production of Time Reference in Indonesian
by Speakers with Aphasia
The
project centers on research to investigate the comprehension and
production of time reference by speakers of Indonesian who suffer from
aphasia. More specifically, the project wants to see whether the adverbs
that denote time reference in Indonesian (which is typologically
classified as an analytic language) are processed in a way comparable to
that of inflections for tense and aspect. Interest on this topic is
motivated by findings from Dutch and Turkish that show that the time
denoted by tense and aspect (past, present, future) seems to influence
the production and comprehension of inflections (e.g. for Dutch Jonkers
and de Bruin, 200 and Bastiaanse, 2008; for Turkish Yarbay Duman and
Bastiaanse, 2009). Two groups of speakers of aphasia will participate in
the research: agrammatic or non-fluent speakers and fluent speakers.
This will enable drawing a comparison between the two groups which are
traditionally differentiated based on the production-comprehension
characteristics. Roughly speaking, grammatic speakers are said to be
impaired in production but have intact comprehension and vice versa for
the fluent speakers with aphasia. It will be seen whether the production
and comprehension of the adverbs denoting time reference in Indonesian
are markedly different or not between the two groups.
Two groups of adverbs will be used in the project. Temporal or lexical adverbs, such as kemarin “yesterday” and aspectual adverbs, such as sudah
“already,” will be used in both the production and comprehension tests.
The two kinds of adverbs differ in their syntactic property in that the
former’s scope is sentential and the latter’s is a part of the Verb
Phrase (VP) (Butar-Butar, 1976). Their semantic property also differs as
the former kind of adverbs is classified as nouns and the latter as
adverbs (Kamus Besar Bahasa Indonesia,
2005). To support the expected findings from the aphasia tests, an ERP
(Event-Related Potentials) experiment will be conducted with Indonesian
speakers without any history of neurological disease to establish that
the two kinds of adverbs are indeed processed differently.
For
the aphasia experiment, besides the data obtained from testing, this
project will also collect some spontaneous speech data that will be
analyzed for other linguistic aspects besides adverbs denoting time
reference. Together with the data from tests, these spontaneous speech
data can provide some glimpse on how aphasia influences the production
of Indonesian, which is very different from the inflectional languages
that have been extensively described in the literature.
