This study investigated the effects of varying the complexity of writt
en Chinese characters in a lexical decision task. Forty adult Chinese
students (20 from Mainland China and 20 from Taiwan) participated in t
he study. Subjects responded to individual characters presented by a t
achistoscope and classified as simplified legal, complex legal, and il
legal. Reaction times and correct responses by nationality were analyz
ed using analysis of variance and multiple regression. One result indi
cates that the number of strokes in a Chinese character affects reacti
on time when subjects identify characters they most often read. This r
esult is consistent with well-documented findings that the number of l
etters in English words affect processing time. However, another resul
t indicates that the fewer number of strokes in simplified characters
did not lead to faster reaction times when compared to complex charact
ers. The theoretical implications of the results are discussed in term
s of how basic perceptual processes may interact with the characterist
ics of an orthography to maintain optimal processing speed during read
ing. (C) 1994 Academic Press, Inc.
