The purpose of this paper is to elaborate on the assimilation patterns of Perceptual Assimilation Model-L2(PAM-L2) by adopting the concept of ‘fit index’ conceived by Guion et al.(2000) and explore the variations of foreign speech perception predicted in PAM-L2’s framework. In the experiment, 33 college students participated in the online POSE tests and the results of 6 English vowel pairs ( /i-ɪ/, /ɪ-ɛ/, /ɛ-æ/, /u-ʊ/, /æ-ɑ/, /ʌ-ɑ/) were analyzed. By using the fit indexes, /i-ɪ/ and /ɛ-æ/ pairs were categorized as SC, /u-ʊ/ pair as CG, and /æ-ɑ/ and /ɪ-ɛ/ pairs as TC. The vowel /ʌ-ɑ/ pair was analyzed as UC type and excluded in the discussion. The perception accuracy of TC was 75%, and the perception accuracy was 50% for both CG and SC types. In general, the results substantiate the predictions of PAM-L2. In addition, the results from the POSE test showed lower perceptual accuracy rates than those from the previous studies, which may be resulted by the different types of perception experiments exercised in the research.
