英文摘要
The major objective of this research is to investigate, in the
normal brain, the hemispheric for semantic functions which may
be impaired in thought disorders. The proposed studies will use
visual half-field stimulation to investigate semantic facilitation
and inhibition processes in the left and right hemispheres of
normal individuals. The primary hypothesis is that the left
hemisphere processes meaning in a focal manner, by facilitating
relevant meanings and inhibiting those deemed irrelevant, while
the right hemisphere maintains facilitation for a set of
semantically related meanings without inhibition. The role of
attentional selectivity in semantic processing in each cerebral
hemisphere will be examined in three series of experiments. In
Series 1, lexical priming paradigms will be used to investigate the
role of semantic expectancies in producing semantic inhibition
and facilitation. In Series 2, the "negative priming" paradigm will
be used to investigate facilitatory and inhibitory processes
produced when one of two simultaneously presented words is the
focus of visual attention. In Series 3, semantic facilitation and
inhibition are examined in higher order cognitive tasks which
required judgments of meaning. It is predicted that semantic
facilitation will occur in both cerebral hemispheres, but that
inhibitory processes, which depend upon attentional selection, will
be restricted to the left hemisphere. It is important to
understand the neurological basis of these functions, since
breakdowns in the normal interplay of semantic facilitation and
inhibition could produce some schizophrenic symptoms (e.g., loose
associations).
