The Effects of Top-down and Bottom-up Cognitive Processes in Chinese EFL Learners’ Incidental Vocabulary Acquisition

Abstract

This study analyzed the correlation between the incidental acquisition of vocabulary using different processing strategies during reading by 56 native Chinese-speaking students studying English at a university in China. Based on top-down and bottom-up cognitive processes, the study discussed the lexical processing strategies employed by the participants in analyzing unknown words. Based on introspective data collected during think-aloud and the subsequent vocabulary retention test results, the researcher explored the acquisition effects of different strategies. The results indicated that the bottom-up processing strategy showed better acquisition effects than the top-down strategy. Finally, the researcher discussed the reasons why Chinese college students performed better with the bottom-up cognitive approach in incidental vocabulary acquisition while reading, attempting to provide pedagogical implications for L2 vocabulary teaching in China.
