Amplitude envelope perception, phonology and prosodic sensitivity in children with developmental dyslexia

Here we explore relations between auditory perception of amplitude envelope structure, prosodic sensitivity, and phonological awareness in a sample of 56 typically-developing children and children with developmental dyslexia. We examine whether rise time sensitivity is linked to prosodic sensitivity, and whether prosodic sensitivity is linked to phonological awareness. Prosodic sensitivity was measured by two reiterant speech tasks modelled on Kitzen (2001). The children with developmental dyslexia were significantly impaired in the reiterant speech tasks and in the phonological awareness tasks (onset and rime awareness). There were significant predictive relations between basic auditory processing of amplitude envelope structure (in particular, rise time), prosodic sensitivity, phonological awareness, reading, and spelling. The auditory processing difficulties that characterise children with developmental dyslexia appear to impair their sensitivity to phrase-level prosodic cues such as metrical structure as well as to phonology, but in this study phonological and prosodic sensitivity made largely independent contributions to reading.     

Prosodic reading,reading comprehension and morphological skills in Hebrew‐speaking fourth graders

Employing prosody skilfully, one of the cornerstones of fluent reading, is an indicator of text comprehension. Morphological knowledge has been shown to underlie lexical acquisition and to be related to reading development. The relationship between reading comprehension, prosodic reading and morphological knowledge was investigated in 51 Hebrew‐speaking fourth‐grade students aged 9–10. Participants were tested on comprehension of two stories and on appropriate prosodic reading of one of them. Their prosodic reading was compared with an agreed prosodic map compiled from experts' reading. Participants were also administered a battery of morphological tasks. All three domains, including almost all of their component parts, were strongly correlated. The multiple regression in steps showed that morphology and reading comprehension each contribute to prosodic reading, while morphology and prosody each contribute to reading comprehension. The connection between reading comprehension and prosodic reading is however moderated by good morphological skills.     

The relationship between prosodic perception,phonological awareness and vocabulary in emergent literacy

Studies have begun to focus on what skills contribute to the development of phonological awareness, an important predictor of reading attainment. One of these skills is the perception of prosody, which is the rhythm, tempo and stress of a language. To examine whether prosodic perception contributes to phonological awareness prior to reading tuition, we assessed 49 prereaders. Using confirmatory factor analysis, we found that measures of prosodic perception and phonological awareness loaded onto separate factors. Our regression analyses revealed that prosodic perception accounted for significant variance after partialling out definitional vocabulary and memory for digits, but not after accounting for receptive vocabulary. Based on the independence of prosodic perception from definitional vocabulary, we concluded that prosodic perception contributes to the development of phonological awareness indirectly through receptive vocabulary, by improving speech‐processing skills, but independently of semantic knowledge. Further studies should examine the role of prosody in children at risk of later reading difficulties.     

A cross‐sectional study of prosodic sensitivity and reading difficulties

In this cross‐sectional study, we explore the relationship between prosodic sensitivity (suprasegmental phonology) and phonological awareness (segmental phonology) and investigate whether a group of poor readers display significant suprasegmental phonological deficits in comparison to chronological age‐matched controls and younger, reading age‐matched controls. Phonological awareness assessments were administered along with a battery of prosodic sensitivity assessments drawn from recent literature. The results showed that poor readers were outperformed by their chronological age‐matched counterparts on all measures of prosodic sensitivity. A significant main effect of group was found on the revised stress mispronunciations task and the stress assignment task from the prosodic assessment battery, the former of which remained even after controlling for individual differences in receptive vocabulary and measures of phonological awareness. Significant relationships were also found between measures of prosodic sensitivity and phonological awareness (especially phoneme awareness). These findings emphasise the importance of both segmental and suprasegmental phonological skills in children's reading development.     

Prosody and alignment: a sequential perspective

In their analysis of a corpus of classroom interactions in an inner city high school, Roth and Tobin describe how teachers and students accomplish interactional alignment by prosodically matching each other’s turns. Prosodic matching, and specific prosodic patterns are interpreted as signs of, and contributions to successful interactional outcomes and positive emotions. Lack of prosodic matching, and other specific prosodic patterns are interpreted as features of unsuccessful interactions, and negative emotions. This forum focuses on the article’s analysis of the relation between interpersonal alignment, emotion and prosody. It argues that prosodic matching, and other prosodic linking practices, play a primarily sequential role, i.e. one that displays the way in which participants place and design their turns in relation to other participants’ turns. Prosodic matching, rather than being a conversational action in itself, is argued to be an interactional practice (Schegloff 1997), which is not always employed for the accomplishment of ‘positive’, or aligning actions.

Examining the independent contribution of prosodic sensitivity to word reading and spelling in early readers

This study was designed to examine the independent contribution of prosodic sensitivity—the rhythmic patterning of speech—to word reading and spelling in a sample of early readers. Ninety-three English-speaking children aged 5–6 years old (M = 69.28 months, SD = 3.67) were assessed for their prosodic sensitivity, vocabulary knowledge, phonological, and morphological awareness (predictor variables) along with their word reading and spelling (criterion variables). Bivariate (zero-order) correlation analyses revealed that prosodic sensitivity was significantly associated with all other variables in this study. Hierarchical regression analyses revealed that after controlling for individual differences in vocabulary, phonological, and morphological awareness, prosodic sensitivity was still able to explain unique variance in word reading, but was unable to make an independent contribution to spelling. The findings suggest that prosodic sensitivity gives added value to our understanding of children’s reading development.     

Auditory temporal structure processing in dyslexia: processing of prosodic phrase boundaries is not impaired in children with dyslexia

Reading disability in children with dyslexia has been proposed to reflect impairment in auditory timing perception. We investigated one aspect of timing perception—temporal grouping—as present in prosodic phrase boundaries of natural speech, in age-matched groups of children, ages 6–8 years, with and without dyslexia. Prosodic phrase boundaries are characterized by temporal grouping of functionally related speech elements and can facilitate syntactic processing of speech. For example, temporary syntactic ambiguities, such as early-closure structures, are processed faster when prosodic phrase boundaries are present. We examined children’s prosodic facilitation by measuring their efficiency of sentence processing for temporary syntactic ambiguities spoken with (facilitating) versus without (neutral) prosodic phrase boundaries. Both groups of children benefited similarly from prosodic facilitation, displaying faster reaction times in facilitating compared to neutral prosody. These findings indicate that the use of prosodic phrase boundaries for speech processing is not impaired in children with dyslexia.

A cross‐sectional study of fluency and reading comprehension in Spanish primary school children

The importance of prosodic elements is recognised in most definitions of fluency. Although speed and accuracy have been typically considered the constituents of reading fluency, prosody is emerging as an additional component. The relevance of prosody in comprehension is increasingly recognised in the latest studies. The purpose of this research is to examine the contribution of prosodic reading to comprehension beyond automaticity in word reading, taking into account children's grade level. One hundred and twenty‐two Spanish children (74 second and 48 fourth graders) were tested in prosodic reading, automaticity in word reading (nonword reading and reading rate) and comprehension abilities. Results show that the contribution of automaticity in word reading is relevant in both grades; however, it is more significant in Grade 2. The prosodic components of reading seem to be related differently to comprehension across grades, intonation being the highest predictor of comprehension in Grade 4. Implications for educational practice are discussed.     

Prosodic and phonemic awareness in children’s reading of long and short words

Phonemic and prosodic awareness are both phonological processes that operate at different levels: the former at the level of the individual sound segment and the latter at the suprasegmental level across syllables. Both have been shown to be related to word reading in young readers. In this study we examine how these processes are differentially related to reading monosyllabic and multisyllabic words. Participants were 110 children in grades four and five who were asked to read monosyllabic and three- and four-syllable words matched for frequency. Phonemic awareness was assessed via a phoneme elision task; prosodic awareness was assessed by a task asking participants to identify the syllable bearing primary stress in a spoken word. Results showed that phonemic and prosodic awareness were independent predictors of short word reading, and both phonological factors made independent contributions to multisyllabic word reading, showing that phonemic and prosodic awareness are complementary but not redundant processes. Only prosodic awareness survived control for simple decoding ability in the reading of long words, suggesting that suprasegmental phonology gives added value to our understanding of reading multisyllabic words.     

Explaining phonology and reading in adult learners: Introducing prosodic awareness and executive functions to reading ability

Background

This study was designed to extend our understanding of phonology and reading to include suprasegmental awareness using measures of prosodic awareness, which are complex tasks that tap into the rhythmic aspects of phonology. By requiring participants to access, reflect on and manipulate word stress, the prosodic awareness measures used here necessarily impose demands on the executive system. Prosodic awareness was evaluated as a phonological predictor of reading in older readers while controlling for executive functions (EF) in order to ascertain whether observed predictive relationships could be confidently attributed to suprasegmental awareness.

Methods

103 adults between 18 and 55 years of age completed tasks on prosodic awareness, EF, vocabulary, nonverbal abilities, naming speed and short‐term memory.

Results

Independent contributions of prosodic awareness added to models of word reading, whereas EF processes did not uniquely contribute to adult reading outcomes.

Conclusions

Suprasegmental phonology explains individual differences in word reading among experienced readers. Theoretical implications of findings are discussed.

Implications for Practice

What is already known about this topic

• Phonological awareness (PA) becomes less predictive of reading in older readers. PA is typically assessed at the level of the segment (e.g., phonemes, syllables and onset‐rimes), with less focus on suprasegmental processes (e.g., rhythm, stress and intonation).
• Suprasegmental phonological processing includes measures of prosodic ability (e.g., awareness and manipulation of suprasegmental features of oral language). Studies on prosodic awareness and reading have independent contributions beyond segmental PA in early readers. Less work has been investigated among adult readers.
• Executive functions (EF) including inhibitory control, working memory, switching and updating and monitoring of goal directed behaviour, predict overall academic achievement. Limited studies have controlled for EF demands in phonological tasks.

What this paper adds

• Tasks of prosodic awareness necessarily impose demands on the executive system when manipulating components of oral language. After controlling for EF and controls, prosodic awareness explained individual differences in adult word reading.
• Tasks of suprasegmental phonological processes explain the association between phonology and reading in older and more experienced readers. Researchers who explore phonology and reading development should begin to include tasks of prosodic awareness to examine the dual role of segmental and suprasegmental PA as it is implicated across development.

Implications for theory, policy or practice

• Theoretical models of phonology and reading can be extended to include suprasegmental processes.
• For educational practitioners involved in reading assessment of older readers, tasks of prosodic awareness are a more age‐appropriate measure of phonology.
• Tasks of phonology and reading with increasing complexity impose greater demands on the executive system. The relationship between cognitive flexibility and reading needs to be considered in theoretical models of reading.

The role of prosodic sensitivity in children's reading development

While the critical importance of phonological awareness (segmental phonology) to reading ability is well established, the potential role of prosody (suprasegmental phonology) in reading development has only recently been explored. This study examined the relationship between children's prosodic skills and reading ability. Hierarchical multiple regression analyses examined the unique contribution of word‐level and phrase‐level prosodic skills to the prediction of three concurrent measures of reading ability in 81 fourth‐grade children (mean age 9.3 years). After controlling for phonological awareness and general rhythmic sensitivity, children's prosodic skills predicted unique variation in word‐reading accuracy and in reading comprehension. Phrase‐level prosodic skills, assessed by means of a reiterative speech task, predicted unique variance in reading comprehension, after controlling for word reading accuracy, phonological awareness and general rhythmic sensitivity. These results add to the growing body of evidence of the importance of prosodic skills in reading development.     

Function words in the prosody of fluent reading

This paper exposes how function words and their prosodic features play a part in learning and teaching to read in the early years. It sketches the place that function words have in the grammar of English and describes their phonological features, especially their weak stress and its role in the prosodic quality of sentences. It considers the ways that function words and their prosodic features have a place in promoting fluent reading, taking into account accurate recognition of function words and well‐paced phrasing.     

Intonation and communicative intent in mothers' speech to infants: is the melody the message?

This study explores the power of intonation to convey meaningful information about the communicative intent of the speaker in speech addressed to preverbal infants and in speech addressed to adults. Natural samples of infant- and adult-directed speech were recorded from 5 mothers of 12-month-old infants, in 5 standardized interactional contexts: Attention-bid, Approval, Prohibition, Comfort, and Game/Telephone. 25 infant-directed and 25 adult-directed vocalizations were electronically filtered to eliminate linguistic content. The content-filtered speech stimuli were presented to 80 adult subjects: 40 experienced parents and 40 students inexperienced with infants. The subjects' task was to identify the communicative intent of the speaker using only prosodic information, given a 5-alternative forced choice. Listeners were able to use intonation to identify the speaker's intent with significantly higher accuracy in infant-directed speech than in adult-directed speech. These findings suggest that the prosodic patterns of speech to infants are more informative than those of adult-adult speech, and may provide the infant with reliable cues to the communicative intent of the speaker. The interpretation of these results proposed here is that the relation of prosodic form to communicative function is made uniquely salient in the melodies of mothers' speech, and that these characteristic prosodic patterns are potentially meaningful to the preverbal infant.     

Segmenting Texts Into Meaningful Word Groups: Beginning Readers’ Prosody and Comprehension

It was hypothesized that prosodic reading facilitates beginning readers’ comprehension by allowing them to segment the text into meaningful word groups. Two prosodic features of the oral reading of second-grade students were considered: lack of inappropriate pauses and attention to punctuation. To examine the unique contribution of these features to reading comprehension, fluency (speed and accuracy of reading) and vocabulary were controlled. As expected, both prosodic features were significantly related to comprehension, jointly explaining as much variance as fluency. Accordingly, it might be counterproductive to encourage reading speed and accuracy at the expense of prosody.     

Solidarity and conflict: aligned and misaligned prosody as a transactional resource in intra- and intercultural communication involving power differences

This ethnographic study of teaching and learning in urban high school science classes investigates the ways in which teachers and students talk, gesture, and use space and time in interaction rituals. In situations where teachers coteach as a means of learning to teach in inner-city schools, successful teacher-teacher collaborations are characterized by prosodic expressions that converge over time and adapt to match the prosodic parameters of students’ talk. In these situations our ethnographic data provide evidence of solidarity and positive emotions among the teachers and also between students and teachers. Unsuccessful collaborations are associated with considerable differences in pitch between consecutive speakers participating in turns-at-talk, these being related to the production of negative emotions and conflicts at longer time scales. Situational conflicts are co-expressed by increases in pitch levels, speech intensities, and speech rates; and conflict resolution is accelerated by the coordination of pitch levels. Our study therefore suggests that prosodic alignment and misalignment are resources that are pragmatically deployed to manage face-to-face interactions that have solidarity and conflict as their longer-term outcomes.     

Prosodic awareness is related to reading ability in children with autism spectrum disorders

Prosodic awareness has been linked with reading accuracy in typically developing children. Although children with autism spectrum disorders (ASD) often have difficulty processing prosody and often have trouble learning to read, no previous study has looked at the link between explicit prosodic awareness and reading in ASD. In the current study, 29 early readers with ASD (5–11 years) completed word and nonword reading accuracy tasks and two measures of prosodic awareness. Tasks relating to phonological awareness, oral language, vocabulary, letter knowledge and nonverbal intelligence were also administered. A key finding was that there was a relationship between prosodic awareness and both word and nonword reading accuracy.
