Title: When More is Better: The Power of Megastudies in Understanding Chinese Word Recognition

Abstract:

The speed and accuracy of word recognition depend on various lexical variables, such as word frequency. Traditional psycholinguistic experiments typically use a factorial-design approach, wherein small, carefully matched word sets are used to isolate specific lexical factors. However, this strategy may yield biased conclusions due to limited sample sizes, reduced generalizability, and oversimplification of continuous variables into dichotomous categories.

In this talk, I introduce the megastudy approach, exemplified by the Chinese Lexicon Project: a large-scale initiative that compiles extensive databases of thousands of words. These databases encompass multiple lexical dimensions (orthography, phonology, semantics) and systematically record participants’ reaction times and accuracies in lexical decision and naming tasks. By analyzing data at the word level across a broad spectrum of variables, megastudies address the limitations of conventional factorial designs and yield more robust, generalizable insights into language processing.

I will highlight some key findings from our analyses of over 25,000 two-character Chinese words. The talk will also discuss how megastudy databases facilitate the replication of established findings and provide accessible resources for designing rigorous experiments and exploring new research questions. This approach advances our understanding of language processing in Chinese and carries broader implications for psycholinguistic research across multiple languages.

Professor Chi-Shing Tse is currently a Professor in the Department of Educational Psychology at The Chinese University of Hong Kong. He earned his bachelor’s degree in Cognitive Science from University of Hong Kong, completed his Ph.D. at University at Albany, State University of New York, and subsequently held a postdoctoral position at Washington University in St. Louis. Professor Tse’s research interests span multiple domains within cognitive psychology, including autobiographical memory, conceptual metaphors, psychological well-being, and psycholinguistics. He has published extensively, with more than 80 peer-reviewed journal articles. Currently, Professor Tse leads the Chinese Lexicon Project, a large-scale research initiative investigating Chinese word recognition processes through an innovative megastudy approach.
