Scientific questions:
Grammatical representation in the brain
Grammar, the rules that allow infinite sentences to be built based on a finite set of words, is an essential component of languages. How are grammatical properties of words of various classes captured by the cognitive/neural system? How does the brain “compute” the agreements (e.g., case, tense, grammatical gender) between words so that grammatical sentences are produced to convey a message? How do the language-specific linguistic factors affect the cognitive processes? We attempt to tackle these issues by studying 1) brain-damaged individuals who show varied types of noun/verb dissociations in their deficit patterns 2) how normal speakers process nominal/verbal agreements in production. In particular, we try to understand how the contrast between Chinese language and Indo-European languages might give us special insights into the issue.
Writing and Reading
Chinese characters are complex things. Reading and writing them involve analyses and production of strokes in complicated ways. What guides the reading and writing of these structures and how do these structures make contact with word meaning and sound? We investigate various aspects of the reading and writing processes of Chinese characters/words by looking at how the system breaks down due to brain injury in patients with acquired dyslexia (problems with reading) and acquired dysgraphia (problems with writing). Our focus is what we can learn about the universal mechanisms of reading and writing in general from studying unique aspects of Chinese patients.
Approaches:
Cognitive Neuropsychology
By studying Chinese patients with language disorders resulting from brain damage, we can make inferences about the kinds of cognitive representations and processes that constitute the normal language system.
Cognitive Psychology
Studies of unimpaired individuals' performance on language production tasks, using behavioral measures like reaction time, answer fine-grained questions about the structure of representations and the time course of processing.
Special issue
We organized a “Promoting Cognitive Neuropsychology in China” workshop in April, 2006. Some talks were collected and published in a special issue of a Chinese journal “Advances in Psychological Science”, as listed below :
