Abstract

Categorical approaches to lexical stress typically assume that words have either regular or irregular stress, and imply that only the latter needs to be stored in the lexicon, while the former can be derived by rule. In this paper, we compare these two groups of words in a lexical decision task in Portuguese to examine whether the dichotomy in question affects lexical retrieval latencies in native speakers, which could indirectly reveal different processing patterns. Our results show no statistically credible effect of stress regularity on reaction times, even when lexical frequency, neighborhood density, and phonotactic probability are taken into consideration. The lack of an effect is consistent with a probabilistic approach to stress, not with a categorical (traditional) approach where syllables are either light or heavy and stress is either regular or irregular. We show that the posterior distribution of credible effect sizes of regularity is almost entirely (96.28%) within the region of practical equivalence, which provides strong evidence that no effect of regularity exists in the lexical decision data modelled. Frequency and phonotactic probability, in contrast, showed statistically credible effects given the experimental data modelled, which is consistent with the literature.
葡萄牙语重音中的词汇通达
词汇重音的分类方法通常假设单词有规则重音或不规则重音,并暗示只有不规则重音需要存储在词典中,而不规则重音可以根据规则派生。本文通过对葡萄牙语词汇决策任务中这两组词汇的比较,探讨了二分类是否会影响母语使用者的词汇检索潜伏期,从而间接揭示不同的加工模式。我们的研究结果显示,即使将词汇频率、邻域密度和音致化概率考虑在内,应激规律对反应时间也没有统计学上可信的影响。这种效果的缺乏与重音的概率方法是一致的,而不是与音节或轻或重、重音或规则或不规则的分类(传统)方法一致。研究表明,正则性可信效应量的后验分布几乎完全(96.28%)在实际等价区域内,这有力地证明了建模的词汇决策数据中不存在正则性效应。相比之下,在实验数据建模的情况下,频率和音致性概率显示出统计可信的效果,这与文献一致。
