采用定量的“跨语言同化重叠”方法来测试感知同化模型（PAM）的预测，将辨别实验的结果与听者先前报告的同化数据进行比较。该实验检测了巴黎法语（PF）前圆元音/y/和/oe/的歧视。三组不同法语经历的美国英语听者（无法语经历[NoExp]、有法语经历[ModExp]和有法语经历+法语经历[HiExp]）对PF /y-u/、/y-o/、/ e-o/、/ e-u/、/y-i/、/ e-epsilon/、/ e-i/、/y-oe/、/u-i/和/a-epsilon/进行了区分。元音出现在双音节/rabVp/和肺泡/radVt/上下文中。PF前后圆元音对（16%）的错误率高于PF前后圆元音对（2%）的错误率。总的来说，ModExp侦听器的执行并不比NoExp侦听器更准确（11%的错误）（13%的错误）。尽管HiExp听众对PF /y-u/的辨别仍然相对较差（12%的错误），但与单独的正式经验相比，广泛的沉浸体验与更少的错误相关（3%）。在肺泡上下文中，前后圆元音对的错误发生率（20%）高于双元音对（11%）。听者的同化重叠分数与其辨别错误之间存在显著的相关性，这表明PAM可能扩展到第二语言（L2）元音学习。(C) 2009美国声学学会。(DOI: 10.1121/1.3224715)
A quantitative "cross-language assimilation overlap" method for testing predictions of the Perceptual Assimilation Model (PAM) was implemented to compare results of a discrimination experiment with the listeners' previously reported assimilation data. The experiment examined discrimination of Parisian French (PF) front rounded vowels /y/ and /oe/. Three groups of American English listeners differing in their French experience (no experience [NoExp], formal experience [ModExp], and extensive formal-plus-immersion experience [HiExp]) performed discrimination of PF /y-u/, /y-o/, /oe-o/, /oe-u/, /y-i/, /y-epsilon/, /oe-epsilon/, /oe-i/, /y-oe/, /u-i/, and /a-epsilon/. Vowels were in bilabial /rabVp/ and alveolar /radVt/ contexts. More errors were found for PF front vs back rounded vowel pairs (16%) than for PF front unrounded vs rounded pairs (2%). Overall, ModExp listeners did not perform more accurately (11% errors) than NoExp listeners (13% errors). Extensive immersion experience, however, was associated with fewer errors (3%) than formal experience alone, although discrimination of PF /y-u/ remained relatively poor (12% errors) for HiExp listeners. More errors occurred on pairs involving front vs back rounded vowels in alveolar context (20% errors) than in bilabial (11% errors). Significant correlations were revealed between listeners' assimilation overlap scores and their discrimination errors, suggesting that the PAM may be extended to second-language (L2) vowel learning.
