英文摘要
The proposed research will examine how the limited capacity of working
memory constrains the on-line processing in language comprehension.
Comprehension performance changes qualitatively and quantitatively when
the resource demands of the task exceed the supply. The proposed research
experimentally examines I what kinds of task demands exacerbate resource
shortages, how resource shortages are accommodated by the, i system, and
how individual differences in maximum capacity affect performance.
The empirical studies examine working memory constraints on four aspects
of language comprehension. One series of experiments investigates the
relation between syntactic modularity and working memory capacity,
examining the hypothesis that a resource-demanding interaction between
syntactic and semantic processing occurs only in those Individuals and
tasks in which the required resources are available. A second series
examines whether the larger capacity of some individuals permits them to
maintain multiple Interpretations of a structurally or lexically ambiguous
sentence. A third series investigates how the storage of information over
a text distance varies with the processing demands made by the intervening
text. A fourth series develops the methodology of pupillometry to index
the consumption of cognitive resources during language comprehension. In
addition, the experimental methodologies include the measurement of gaze
locations and durations during reading, measurement of word-by-word self-
paced reading times, and cross-modal priming. The methodologies are used
to answer questions about the time course, content, and intensity of
processing.
The theory will be instantiated as a computational model, namely an
activation-based production system , in which both processing and storage
are fueled by activation. In this model, the total amount of activation,
available to the system has an upperbound that corresponds to the maximum
capacity of an individual. The goal of the theory is to explain how the
processing of language accommodates (or fails to accommodate) tile
transient computational and storage demands that occur in language
comprehension, and to thereby explain the variation in comprehension among
tasks and individuals.
One health-related implication of this research is that the theory will
explain a dimension of individual differences that potentially encompasses
not just normal variation in comprehension, but also variation due to
extreme age, to stress, or to trauma. Second, the research develops new
methodologies with clinical potential (relating eye fixations to cognitive
processes and relating pupil dilation to the consumption of cognitive
resources). Third, the research develops the theoretical analysis of a
psychometric instrument (the reading span test) that may prove useful for
measuring age and disease-related changes in language functioning.
