Bodies and codas or core syllables plus appendices? Evidence for a developmental theory of subsyllabic division preference

Two experiments examining the subsyllabic division behaviors of Chinese-speaking children learning English as a foreign language (EFL) are reported. In Experiment 1, target phonemes of monosyllabic English nonwords were varied in phonotactic context (e.g., (C)VC vs. (C)CVC), marginality (e.g., (C)CVC vs. C(C)VC), and/or position (e.g., (C)VC vs. CV(C)) in phoneme deletion and isolation tasks, with confounds such as global similarity, vowel length, and targets’ sonority controlled. The fourth graders found the initial obstruent more difficult to isolate when it constituted the onset itself, i.e., (C)VC, than when it was part of a clustered onset, i.e., (C)CVC; no such difference was observed (non)word-finally, however. The results thus failed to support a subsyllabic preference for either onsets and rimes or bodies and codas. In Experiment 2, 49 second graders were tested on two other sets of phoneme awareness tasks and similar results were obtained. Items of one task were adapted from Hulme et al. (2002), in which the English-speaking first graders found the initial phoneme of a clustered onset, i.e., (C)CVC, more difficult to delete than the cluster as a whole, i.e., (CC)VC. The opposite patterns were observed with the Chinese EFL learners in Experiment 2, who found instead the initial consonant easier to remove. Taken together, the results suggested that Chinese-speaking EFL children process an English syllable as a linear combination of an intact core syllable (i.e., CV) plus its appendices. In both experiments, moreover, only performance in segmenting core syllable, but not that of segmenting appendices from the core syllable, predicted decoding success, a pattern again opposite to that of Hulme et al. (2002). The seemingly conflicting results were nevertheless consistent with a general developmental account of intra-syllabic division preference.     

The role of phonemes and syllables in the perceived similarity of speech sounds for children

In two experiments, we investigated the factors that influence the perceived similarity of speech sounds at two developmental levels. Kindergartners and second graders were asked to classify nonsense words, which were related by syllable and phoneme correspondences. The results support the existence of a developmental trend toward increased attention to individual phonemic segments. Moreover, one significant factor in determining the perceived similarity of speech sounds appears to be the position of the component correspondences; attention to the beginning of utterances may have developmental priority. An unexpected finding was that the linguistic status of the unit involved in a correspondence (whether it was a syllable or a phoneme) did not seem particularly important. Apparently, the factors which contribute to the perceived similarity of speech sounds in the classification task are not identical to those which underlie performance in explicit segmentation and manipulation tasks, since in the latter sort of task, syllables are more accessible than phonemes for young children. The present task may tap a level of processing that is closer to the one entailed in word recognition and lexical access.     

Phonemes matter: the role of phoneme-level awareness in emergent Chinese readers

The importance of phonological awareness for learning to read may depend on the linguistic properties of a language. This study provides a careful examination of this language-specific theory by exploring the role of phoneme-level awareness in Mandarin Chinese, a language with an orthography that, at its surface, appears to require little phoneme-level insight. A sample of 71 monolingual Mandarin-speaking children completed a phonological elision task and a measure of single-character reading. In this sample, 4- and 5-year-old preschoolers were unable to complete phoneme-level deletions, whereas 6- to 8-year-old first graders were able to complete initial, final, and medial phoneme-level deletions. In this older group, performance on phoneme deletions was significantly related to reading ability even after controlling for syllable- and onset/rime-level awareness, vocabulary, and Pinyin knowledge. We believe that these results reopen the question of the role of phonological awareness in reading in Chinese and, more generally, the nature of the mechanisms underlying this relationship.     

Explicit syllable and phoneme segmentation in the young child

To write a language, one must first abstract the unit to be used from the acoustic stream of speech. Writing systems based on the meaningless units, syllables and phonemes, were late developments in the history of written language. The alphabetic system, which requires abstraction of the phonemic unit of speech, was the last to appear, evolved from a syllabary and, unlike the other systems, was apparently invented only once. It might therefore be supposed that phoneme segmentation is particularly difficult and more difficult, indeed, than syllable segmentation. Speech research suggests reasons why this may be so. The present study provides direct evidence of a similar developmental ordering of syllable and phoneme segmentation abilities in the young child. By means of a task which required preschool, kindergarten, and first-grade children to tap out the number of segments in spoken utterances, it was found that, though ability in both syllable and phoneme segmentation increased with grade level, analysis into phonemes was significantly harder and perfected later than analysis into syllables. The relative difficulties of the different units of segmentation are discussed in relation to reading acquisition.

Not all phonological awareness deficits are created equal: evidence from a comparison between children with Otitis Media and poor readers

Children with reading difficulties and children with a history of repeated ear infections (Otitis Media, OM) are both thought to have phonological impairments, but for quite different reasons. This paper examines the profile of phonological and morphological awareness in poor readers and children with OM. Thirty‐three poor readers were compared to individually matched chronological age and reading age controls. Their phonological awareness and morphological awareness skills were consistently at the level of reading age matched controls. Unexpectedly, a significant minority (25%) of the poor readers had some degree of undiagnosed mild or very mild hearing loss. Twenty‐nine children with a history of OM and their matched controls completed the same battery of tasks. They showed relatively small delays in their literacy and showed no impairment in morphological awareness but had phonological awareness scores below the level of reading age matched controls. Further analysis suggested that this weakness in phonological awareness was carried by a specific weakness in segmenting and blending phonemes, with relatively good performance on phoneme manipulation tasks. Results suggest that children with OM show a circumscribed deficit in phoneme segmentation and blending, while poor readers show a broader metalinguistic impairment which is more closely associated with reading difficulties.     

Phonemes: Lexical access and beyond

Phonemes play a central role in traditional theories as units of speech perception and access codes to lexical representations. Phonemes have two essential properties: they are ‘segment-sized’ (the size of a consonant or vowel) and abstract (a single phoneme may be have different acoustic realisations). Nevertheless, there is a long history of challenging the phoneme hypothesis, with some theorists arguing for differently sized phonological units (e.g. features or syllables) and others rejecting abstract codes in favour of representations that encode detailed acoustic properties of the stimulus. The phoneme hypothesis is the minority view today. We defend the phoneme hypothesis in two complementary ways. First, we show that rejection of phonemes is based on a flawed interpretation of empirical findings. For example, it is commonly argued that the failure to find acoustic invariances for phonemes rules out phonemes. However, the lack of invariance is only a problem on the assumption that speech perception is a bottom-up process. If learned sublexical codes are modified by top-down constraints (which they are), then this argument loses all force. Second, we provide strong positive evidence for phonemes on the basis of linguistic data. Almost all findings that are taken (incorrectly) as evidence against phonemes are based on psycholinguistic studies of single words. However, phonemes were first introduced in linguistics, and the best evidence for phonemes comes from linguistic analyses of complex word forms and sentences. In short, the rejection of phonemes is based on a false analysis and a too-narrow consideration of the relevant data.     

The secret is in the sound: from unsegmented speech to lexical categories

When learning language, young children are faced with many seemingly formidable challenges, including discovering words embedded in a continuous stream of sounds and determining what role these words play in syntactic constructions. We suggest that knowledge of phoneme distributions may play a crucial part in helping children segment words and determine their lexical category, and we propose an integrated model of how children might go from unsegmented speech to lexical categories. We corroborated this theoretical model using a two‐stage computational analysis of a large corpus of English child‐directed speech. First, we used transition probabilities between phonemes to find words in unsegmented speech. Second, we used distributional information about word edges – the beginning and ending phonemes of words – to predict whether the segmented words from the first stage were nouns, verbs, or something else. The results indicate that discovering lexical units and their associated syntactic category in child‐directed speech is possible by attending to the statistics of single phoneme transitions and word‐initial and final phonemes. Thus, we suggest that a core computational principle in language acquisition is that the same source of information is used to learn about different aspects of linguistic structure.     

Perceptions musicales et conscience phonologique : recherche auprès d’enfants francophones d’âge préscolaire

Research led with English, Turkish and Slovak-speaking preschoolers have shown positive correlations between musical perceptual skills and phonological awareness. However, limited studies have been conducted in other linguistic contexts. In that regard, the aim of this study is to examine the correlation between musical perceptual skills (pitch and duration discrimination) and phonological awareness (syllable, rhyme and phoneme identification; rhyme identification) among 61 Francophone preschoolers (34 girls and 27 boys, mean age 4.7 months). Each participant completed a phonological awareness test, a music perception test and a non-verbal cognitive abilities task (spatial memory). The relationship between musical perceptual skills and phonological awareness was investigated using Pearson product-moment correlation coefficient. Preliminary analyses were performed to ensure no violation of the assumptions of normality, linearity and homoscedasticity. There was a moderate positive correlation between the two variables. The syllable identification task was the only one correlated with both pitch and duration discrimination tasks. It is possible to believe that better perceptual musical abilities improve, even boost, syllable treatment among Francophone preschoolers. Since rhyme and phoneme awareness seem to emerge after syllable awareness, this could explain why no correlation was observed with musical perceptual skills among those young participants.     

Phonological awareness in young Chinese children

Two studies explored the nature of phonological awareness (PA) in Chinese. In Study 1, involving 146 children, awareness of phoneme onset did not differ from chance levels at ages 3-5 years in preschool but increased to 70% correct in first grade, when children first received phonological coding (Pinyin) instruction. Similarly, tone awareness was at better than chance levels from second year kindergarten (age 4), but increased strongly and significantly in first grade to 74% accuracy. In contrast, syllable and rime awareness increased gradually and steadily across ages 3-6 years. Patterns suggest different influences of age and literacy instruction for different PA levels. In Study 2, involving 202 preschoolers, variance in Chinese character recognition was best explained by tasks of syllable awareness, tone awareness, and speeded naming. Findings underscore the unique importance of both tone and syllable for early character acquisition in Chinese children.     

How the Characteristics of Phonemes and Syllabic Structures can Impact the Phonological Awareness of Kindergarten and First-Grade Arabic-Speaking Children

Phonological awareness may be influenced by differences in the characteristics of the items studied. This hypothesis is considered particularly applicable to Arabic, which is a diglossic language. This study examined the impact of phonemic position and the affiliation of the items between spoken and standard languages on phonemic isolation tasks. The data were obtained from 310 native Arabic-speaking kindergarteners and first graders and revealed that for simple and complex monosyllabic pseudo-words, isolating initial phonemes was more difficult than isolating final phonemes. In addition, the items in the spoken language were easier than the items in the standard language for the children at both grade levels. Thus, certain phonological features of the standard language may not be sufficiently developed even after entrance to school, which may explain certain difficulties in reading development in Arabic. The results are discussed in relation to previous findings.     

Using children's humor to clarify the relationship between linguistic awareness and early reading ability.

This study uses linguistic humor to show that an awareness of only those linguistic units transcribed by the orthography bears a special relation to early reading success. The subjects were 48 second-grade children tested on ten "phoneme/morpheme" riddles which manipulate phonemes and bound morphemes and ten "control" riddles which depend on awareness of other aspects of linguistic structure and "common sense". Each child also received the Word Identification and Word Attack subtests of the Woodcock Reading Mastery Tests and the Peabody Picture Vocabulary Test. Reading ability was significantly related to correct resolution of the phoneme/morpheme riddles but not to correct resolution of the control riddles. PPVT scores were significantly related to performance on both types of riddles but not to reading ability. Thus, while IQ is related to the resolution of riddles in general, reading ability has a special relation to riddles which manipulate phonemes and morphemes, consistent with the morphophonological nature of English orthography.     

Situational features influencing young children's mentalistic explanations of action

This research assessed whether variable self-initiated movement and perceptual access to goals influence children to regard an action as mentalistically caused. In Study 1, preschoolers, first graders, and adults chose whether the actions of artifacts, insects, mammals, or humans were caused by mental or physical states. At all ages mental explanations were generally preferred in the presence (but not the absence) of the three situational cues (ps < .001). Also, the proportion of mental explanations by adults, and to a lesser extent by first graders, significantly increased depending upon the biological sophistication of the actor. In Study 2, preschoolers and first graders witnessed scenarios in which the presence of perceptual access or variable self-initiated movement was varied. Spontaneous mentalistic explanations of action were more common in both age groups when the feature of interest was present than when it was absent, ps < .001. Taken together, these studies suggest that children abstract specific features of action when construing its cause across disparate situations and actors and that doing so plays a vital role in learning when to generalize mentalistic explanations to new situations.

Explicit speech segmentation and syllabic onset structure: Developmental trends

Recent applications of the hierarchical theory of the syllable to the development of explicit speech segmentation are critically examined. One particular prediction, that an initial consonant is more easily isolated when it constitutes the complete onset of a syllable than when it is part of a cluster onset, was tested on children with grade levels ranging from kindergarten to second grade. At each level, two independent groups of children worked with either CVCC (first consonant complete onset) or CCVC (part of cluster onset) syllables. First- and second-graders performed better on the CVCC than on the CCVC material in an initial consonant deletion task, but not when the task was comparison on the basis of that consonant. With the same instructions as the older children, kindergarten children performed at floor level on both tasks with both materials. However, in a new experiment in which the deletion task was presented as a puppet game, and with pretraining and selection on vowel deletion, a significantly higher level of success was achieved by the children working with the CVCC material. These results are consistent with the notion of developmental precedence of onset segmentation on phoneme segmentation. On the other hand, the results of the first and second graders show that onset superiority is not specific for the pre-reading stage.     

Mechanisms of aural encoding: VIII. Phonetic interference and context-sensitive coding in short-term memory

In previous experiments Ss were presented for ordered recall with sequences of five consonant phonemes paired with /a/ in which the middle three consonant phonemes shared the same manner of articulation (voiced, unvoiced, nasal), the same place of articulation (front, middle, back), or neither the same manner nor place of articulation (control sequences). Compared to performance in control sequences, the middle consonant phoneme was always more difficult to recall in manner of articulation sequences but not in place of articulation sequences. The results suggested that for these sequences consonant phonemes were not remembered in terms of their place of articulation. In the present experiment, sequences of consonant-vowel (CV) or vowel-consonant (VC) syllables were presented for recall in which each consonant phoneme was paired with a different vowel. When consonant phonemes in the different sequence types were presented for recall with different vowels, phonetic interference was observed for the middle consonant in place of articulation sequences as well as manner of articulation sequences, and the effect was observed in both CV and VC groups. It was suggested that vowels are encoded in short-term memory in terms of their place of articulation and that presenting consonant phonemes for recall with different vowels caused Ss to use this dimension to code consonant phonemes in short-term memory.     

Getting ready for reading: A follow‐up study of inner city second language learners at the end of Key Stage 1

Background: A previous study (Stuart, 1999) showed that early phoneme awareness and phonics teaching improved reading and spelling ability in inner‐city schoolchildren in Key Stage 1, most of whom were learning English as a second language. Aims: The present study, a follow‐up of these children at the end of Key Stage 1, addresses four main questions: (1) Are these improvements maintained to the end of Key Stage 1? (2) Are different patterns of cognitive process evident in the word recognition skills of phonics trained versus untrained children? (3) Do the phonics trained children now also show a significant advantage in reading comprehension? (4) Are there differences in amount of reading, in self‐concept as readers and in oral vocabulary development between phonics trained and untrained children? Relationships between reading and spelling ages and Key Stage 1 SATs levels are also explored. Sample: Data are reported from 101 seven‐year‐olds (85 of whom were second language learners) remaining from the original 112 children reported on previously. Method: Children were tested on four standardized tests of reading, spelling and vocabulary, and on a further six experimental tests of phoneme segmentation, grapheme‐phoneme correspondence knowledge, regular, exception and nonword reading, author recognition and reading self‐concept. Results: Lasting influences of early phoneme awareness and phonics teaching on phoneme awareness, grapheme‐phoneme correspondence knowledge, word reading and spelling were found. Part of the previously untrained group had now received structured phonics teaching, and were therefore treated as a third (late trained) group. Early and late‐trained groups showed similar levels of attainment and similar cognitive processing patterns, which were different from the untrained group. However, there were no influences of training on reading comprehension, self‐concept or oral vocabulary. Conclusions: Early phoneme awareness and phonics training efficiently accelerates the word recognition and spelling skills of first and second language learners alike. However, this is not sufficient to bootstrap the development of language comprehension in the second language learners. Further research is needed into the kinds of language teaching that will best develop their oral and written language comprehension.     

Mechanisms of aural encoding: VI. Consonants and vowels are remembered as subsets of distinctive features

An attempt was made to examine the manner in which consonants and vowels are coded in short-term memory. under identical recall conditions. Ss were presented with sequences of consonant-vowel digrams for serial recall. Sequences were composed of randomly presented consonants paired with/a/ or randomly presented vowels paired with /d/. Halle’s distinctive feature system was used to generate predictions concerning the frequency of intrusion errors. among phonemes. These predictions were based on the assumption that phonemes are discriminated in memory in terms of their component distinctive features, so that intrusions should most frequently occur between phonemes sharing similar distinctive features. The analysis of intrusion errors revealed that each consonant and vowel phoneme was coded m short-term memory by a particular combination of distinctive features which differed from one phoneme to another. A given phoneme was coded by the same set of distinctive features regardless of the number of syllables in the sequence. However, distinctive feature theories were not able to predict the frequency of intrusion errors for phonemes presented in the middle serial positions of a sequence with 100% accuracy. The results of the experiment support the notion that consonant and vowel phonemes are coded in a similar manner in STM and that this coding involves the retention of a specific set of distinctive features for each phoneme.     

Re-evaluating the Time Course of Gender and Phonological Encoding During Silent Monitoring Tasks Estimated by ERP: Serial or Parallel Processing?

Neurolinguistic and psycholinguistic studies suggest that grammatical (gender) and phonological information are retrieved independently and that gender can be accessed before phonological information. This study investigated the relative time courses of gender and phonological encoding using topographic evoked potentials mapping methods. Event-related brain potentials (ERPs) were recorded using a high resolution electroencephalogram (EEG) system (128 channels) during gender and phoneme monitoring in silent picture naming. Behavioural results showed similar reaction times (RT) between gender and word onset (first phoneme) monitoring, and longer RT when monitoring the second syllable onset. Temporal segmentation analysis (defining dominant map topographies using cluster analysis) revealed no timing difference between gender monitoring and word onset monitoring: both effects fall within the same time window at about 270–290 ms after picture presentation. Monitoring a second syllable onset generated a later effect at about 480 ms. Direct comparison between gender and first phoneme monitoring revealed a difference of only 10 ms between tasks at approximately 200 ms. Taken together, these results suggest that lemma retrieval and phonological encoding may proceed in parallel or overlap. Word onset is retrieved simultaneously with gender, while the longer RT and the later ERP effect for second syllable onset reflect that segmental encoding continues incrementally to the following phonemes.     

Effects of hierarchical organization on children's judgments of distance and direction

The impact of the hierarchical organization of a space on judgments of direction and distance was assessed in two studies using two-dimensional models analogous to those used by A. Stevens and P. Coupe (1978, Cognitive Psychology, 10, 422–437). In each study the models contained two stars and were divided into two parts by a curved boundary line. In the Homogeneous condition the stars were located in the same subsection. In the Congruent condition the leftmost star was in the left subsection and the rightmost star was in the right subsection. In the Incongruent condition the rightmost star was in the left subsection and the leftmost star was in the right subsection. In Experiment 1 first graders, third graders, and college students were required to remember the location of the stars. Results indicated that the first and third graders tended to use the relationship between the subsections as a clue to the relationship between the sites within them, thus extending the results of Stevens and Coupe (1978) to children. In Experiment 2 preschoolers, first, and third graders were asked to judge with the materials directly in front of them, which of the two stars was closer to a site located in one of the subsections. Results indicated that the Incongruent condition led to errors among the preschoolers and first graders but not the third graders, thus indicating that these groups tended to judge as closer the site within the same subsection even though it was really farther away. The results of both studies are discussed as indicative of a tendency among young children to impose organization on information encoded in memory and in relation to increases in metric accuracy, decentration, and efficient scanning which enable them to more accurately evaluate when such organization is and is not appropriate. Implications for behavior in large-scale environments are also discussed, with particular reference to the effect of barriers on perceptions of distance and direction.
