This article examines a turning point in the history of the theory of phonological distinctive features. In Morris Halle’s (1959) The Sound Pattern of Russian, features are organized into a contrastive hierarchy designed to minimize the number of specified features. Redundancy rules, however, ensure that the resulting underspecification has no real phonological consequences and, in subsequent generative approaches to phonology, contrastive hierarchies were largely abandoned. We explore how Halle’s hierarchy would have been different if it had been based on phonological patterns such as voicing assimilation, and show that this reorganization makes plausible predictions about other aspects of Russian phonology. We conclude by pointing to recent work in which the concept of a contrastive hierarchy has been revived, illustrating the range of phenomena that this theoretical device can account for if minimizing specifications is not the primary concern.

This study investigated the contribution of second-language (L2) phonetic categorization abilities and vocabulary size to the phonolexical encoding of challenging non-native phonological contrasts into the L2 lexicon. Two groups of German learners of English differing in L2 proficiency (advanced vs. intermediate) participated in an English lexical decision task including words and nonwords with /ɛ/ and /æ/ (/æ/ does not exist in German), an /ɛ/-/æ/ phonetic categorization task and an English vocabulary test. Results showed that the effects of phonetic categorization and vocabulary size on lexical decision performance were modulated by proficiency: categorization predicted /ɛ/-/æ/ nonword rejection accuracy for intermediate learners, whereas vocabulary did so for advanced learners. This suggests that sufficient phonetic identification ability is key for an accurate phonological representation of difficult L2 phones, but, for learners for whom robust phonetic identification is already in place, their ultimate success is tightly linked to their vocabulary size in the L2.

This study examined the effect of written input on the production of word-final vowels (oral: /i/, /e/; nasal: /ɑ̃/, /ɔ̃/) by 100 native Moroccan learners of French as a second language, relying on a pretest/posttest paradigm. During pretest, participants performed a word repetition task. Then, participants were assigned to five experimental (training) conditions, varying in the modality of stimulus presentation (oral vs. written) and in the modality of response (oral vs. written), before their oral production of the word-final vowels was evaluated in the posttest. Results clearly showed that posttest pronunciation accuracy was affected by the presence of orthographic information in the training task. The copy training task was the most efficient at improving posttest accuracy. Results indicate that orthography, and more specifically the written production copy task, helps L2 learners’ pronunciation more efficiently than phonetic correction.

Phonological processes can pose a learning challenge for children, where the surface form for an underlying contrast may vary as a function of the phonological environment. Mandarin tone sandhi is a complex phonological process that requires knowledge about both the tonal and the prosodic context in which it applies. The present study explored the productive knowledge of tone sandhi processes by 108 3- to 5-year-old Mandarin-speaking children and 33 adults. Participants were asked to produce novel tone sandhi compounds in different tonal contexts and prosodic structures. Acoustic analysis showed that 3-year-olds have abstracted the tone sandhi process and can productively apply it to novel disyllabic words across tonal contexts. However, even 5-year-olds still differed from adults in applying tone sandhi in response to the trisyllabic prosodic structure. The results are discussed in terms of the factors that influence how tone sandhi processes, and phonological alternations more generally, are acquired.

A long-standing hypothesis is that rapid automatized naming (RAN) measures access to phonological representations stored in long-term memory, but this has been difficult to test experimentally because phonological representations are mental constructs not easily operationalized. Here, we provide a method to test this theory using rime neighborhood density as an index of phonological representational strength. Thirty adults completed four picture-naming tasks orthogonalized for item composition (repeating vs. nonrepeating) and presentation format (discrete vs. serial). Each task was presented in two dichotomous conditions of rime neighborhood density (dense and sparse). There was no effect of rime neighborhood density on naming speed in the discrete nonrepeated (confrontation naming) task. However, rime neighborhood density significantly facilitated naming speed for serial repeated (i.e., RAN), discrete repeated, and serial nonrepeated tasks (ps<.03). The effect was weakest for confrontation naming (d=0.14) and strongest for both discrete and serial RAN tasks (ds=1.01), suggesting that repeating items, not serial presentation, makes RAN uniquely sensitive to manipulations of rime neighborhood density and, by proxy, phonological representations.

The study tested the impact of the phonological distance between Spoken Arabic (SpA) and Standard Arabic (StA) on quality of phonological representations among kindergarten, first-, second-, and sixth-grade Arabic-speaking children (N = 120). A pronunciation accuracy judgment task targeted three types of StA words that varied in extent of phonological distance from their form in SpA: (a) identical words, with an identical lexical–phonological form in StA and SpA; (b) cognate words, with partially overlapping phonological forms; items in this category varied in degree of phonological distance too; and (c) unique words with entirely different lexical–phonological forms. Multilevel Regression analysis showed that phonological distance had a significant impact on quality of phonological representations across all grades. Growth in quality of phonological representations was mainly noted between the three younger groups and the sixth-graders. Implications for the impact of phonological distance on phonological representations and on language and literacy development are discussed.

To acquire a new word, learners need to create its representation in phonological short-term memory (STM) and then encode it in their long-term memory. Two strategies can enable word representation in STM: universal segmentation and phonological mapping. Universal segmentation is language universal and thus should predict word learning in any language, while phonological mapping is language specific. This study investigates the mechanisms of vocabulary learning through a comparison of vocabulary learning task results in multiple languages. We tested 44 Polish third graders learning English on phonological STM, phonological awareness in Polish and in English, and on three tasks, which involved learning novel word forms in Polish (first language), in English (second language), and in a language that did not resemble any language known to participants (an unknown language). Participants’ English proficiency was controlled through a vocabulary task. The results suggest that word learning engages different mechanisms for familiar and unfamiliar languages. Phonological awareness in English predicted learning second language and unknown language words, and phonological STM predicted learning words of the unknown language. We propose that universal segmentation facilitates word learning only in an unfamiliar language, while in familiar languages speakers use phonological mapping in order to learn new words.

This study investigated the phonological representations of vowels in children's native and non-native lexicons. Two experiments were mispronunciation tasks (i.e., a vowel in words was substituted by another vowel from the same language). These were carried out by Dutch-speaking 9–12-year-old children and Dutch-speaking adults, in their native (Experiment 1, Dutch) and non-native (Experiment 2, English) language. A third experiment tested vowel discrimination. In Dutch, both children and adults could accurately detect mispronunciations. In English, adults, and especially children, detected substitutions of native vowels (i.e., vowels that are present in the Dutch inventory) by non-native vowels more easily than changes in the opposite direction. Experiment 3 revealed that children could accurately discriminate most of the vowels. The results indicate that children's L1 categories strongly influenced their perception of English words. However, the data also reveal a hint of the development of L2 phoneme categories.
