Dupoux等人先前的研究[J. Memory Lang.36，406-421（1997）]表明，与西班牙语参与者相比，法语参与者在区分仅在重音位置上不同的非词方面存在困难。与西班牙语相反，法语没有对比重音，法语参与者对重音对比“充耳不闻”。Dupoux等人使用的实验范式（快速ABX）产生了显著的组间差异，但没有考虑到根据压力“耳聋”对个体进行分类。“个体评估对于研究特殊人群至关重要，例如双语者或受过训练的单语者。本文提出了一种基于短时记忆序列重复任务的更鲁棒的实验范式。在五个法语-西班牙语的跨语言实验中，压力“耳聋”被证明是至关重要的，取决于组合的记忆负荷和语音变异F0。在实验3和4中，观察到法国和西班牙参与者的个人结果的非重叠分布。因此，该范例适合于评估个体参与者的压力性耳聋。(C)2001年，美国声学学会。
Previous research by Dupoux et al. [J. Memory Lang. 36, 406-421 (1997)] has shown that French participants, as opposed to Spanish participants, have difficulties in distinguishing nonwords that differ only in the location of stress. Contrary to Spanish, French does not have contrastive stress, and French participants are "deaf" to stress contrasts. The experimental paradigm used by Dupoux et al. (speeded ABX) yielded significant group differences, but did not allow for a sorting of individuals according to their stress "deafness." Individual assessment is crucial to study special populations, such as bilinguals or trained monolinguals. In this paper, a more robust paradigm based on a short-term memory sequence repetition task is proposed. In five French-Spanish cross-linguistic experiments, stress "deafness" is shown to crucially depend upon a combination of memory load and phonetic variability in F0. In experiments 3 and 4, nonoverlapping distribution of individual results for French and Spanish participants is observed. The paradigm is thus appropriate for assessing stress deafness in individual participants. (C) 2001 Acoustical Society of America.
