The Impact of Using Reading Storybooks and Writing Journal Activities on Print and Phonemic Awareness of Jordanian Kindergarten Children

This study investigated the impact of reading storybooks and writing journal activities on print and phonemic awareness of Jordanian kindergarten children. Subjects participated in book-reading sessions with a print focus, and writing journals. A total of 50 children were recruited for the study from one kindergarten in Irbid City, Jordan. Two intact sections of 25 children each served as experimental and control groups. Pre-test measures of children’s print and phonemic awareness were administered. Subsequently, children in the experimental group participated in 24 small-group reading sessions that included a print focus, and 14 writing journals over a 14-week period. As an alternate condition, control-group children participated in conventional instruction methods only. Post-testing indicated that children who participated in print-focused reading and writing journal sessions outperformed their control group peers on four measures of print awareness (words in print, print concepts, alphabet knowledge and letter discrimination, and literacy terms), and on phonemic awareness (letter sound identification, rhyme, phoneme blending, phoneme segmentation, and phonemic manipulation), as well as overall performance. Implications and future research directions are discussed.

Exploring Phonological Awareness Skills in Children With Intellectual Disability.

The phonological awareness skills of 7- to 8-year-old children with intellectual disability (ID) were compared to those of 4- to 5-year-old typically developing children who were matched for early reading skills, vocabulary, and gender. Globally, children with ID displayed a marked weakness in phonological awareness. Syllable blending, syllable segmentation, and first phoneme detection appeared to be preserved. In contrast, children with ID showed a marked weakness in rhyme detection and a slight weakness in phoneme blending. Two school years later, these deficits no longer remained. Marked weaknesses appeared in phoneme segmentation and first/last phoneme detection. The findings suggest that children with ID display an atypical pattern in phonological awareness that changes with age. The implications for practice and research are discussed.

How African American English-Speaking First Graders Segment and Rhyme Words and Nonwords With Final Consonant Clusters.

This study explored how typically developing 1st grade African American English (AAE) speakers differ from mainstream American English (MAE) speakers in the completion of 2 common phonological awareness tasks (rhyming and phoneme segmentation) when the stimulus items were consonant-vowel-consonant-consonant (CVCC) words and nonwords. Forty-nine 1st graders met criteria for 2 dialect groups: AAE and MAE. Three conditions were tested in each rhyme and segmentation task: Real Words No Model, Real Words With a Model, and Nonwords With a Model. The AAE group had significantly more responses that rhymed CVCC words with consonant-vowel-consonant words and segmented CVCC words as consonant-vowel-consonant than the MAE group across all experimental conditions. In the rhyming task, the presence of a model in the real word condition elicited more reduced final cluster responses for both groups. In the segmentation task, the MAE group was at ceiling, so only the AAE group changed across the different stimulus presentations and reduced the final cluster less often when given a model. Rhyming and phoneme segmentation performance can be influenced by a child's dialect when CVCC words are used.

Individual differences in the signaling of prosodic structure by changes in voice quality

Earlier work has shown that speakers of American English often (although not always) produce irregular pitch periods (or other changes in voice quality) at prosodically significant locations, such as the onset of a new intonational phrase or a pitch-accented syllable, when those constituents begin with a [ + voiced] phonemic segment (Pierrehumbert & Talkin 1992). This tendency varied substantially across 5 speakers of FM-Radio-News-style speech (Dilley et al. 1996). Further work with speakers of a west-coast dialect (Garellek 2012) raised questions about the appearance of this cue at phrase onsets, when the phrase begins with a prosodically weak (lexically unstressed) syllable; this suggests that it occurs only for phrasally-strong (pitch accented) syllables, whether they occur in phrase-initial position or not. In contrast, extensive analysis of voice quality changes in a corpus of imitated utterances produced by speakers of a mid-western dialect (Cole & Shattuck-Hufnagel 2011) clearly shows a tendency for voice-quality changes at the onsets of prosodically weak syllables when they occur at the onsets of intonational phrases. This raises the possibility that individual speakers or dialects may differ in the likelihood of using changes in voice-quality to mark different types of prosodic events, such as phrase onsets vs pitch accents.

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.

Cantonese-Speaking Children Do Not Acquire Tone Perception before Tone Production-A Perceptual and Acoustic Study of Three-Year-Olds' Monosyllabic Tones.

Models of phonological development assume that speech perception precedes speech production and that children acquire suprasegmental features earlier than segmental features. Studies of Chinese-speaking children challenge these assumptions. For example, Chinese-speaking children can produce tones before two-and-a-half years but are not able to discriminate the same tones until after 6 years of age. This study compared the perception and production of monosyllabic Cantonese tones directly in 3 -year-old children. Twenty children and their mothers identified Cantonese tones in a picture identification test and produced monosyllabic tones in a picture labeling task. To control for lexical biases on tone ratings, the mother- and child-productions were low-pass filtered to eliminate lexical information and were presented to five judges for tone classification. Detailed acoustic analysis was performed. Contrary to the view that children master lexical tones earlier than segmental phonemes, results showed that 3-year-old children could not perceive or produce any Cantonese tone with adult-like proficiency and incorrect tone productions were acoustically different from criterion. In contrast to previous findings that Cantonese-speaking children mastered tone production before tone perception, we observed more accuracy during speech perception than production. Findings from Cantonese-speaking children challenge some of the established tenets in theories of phonological development that have been tested mostly with native English speakers.

Forehearing words: Pre-activation of word endings at word onset.

Occurring at rates up to 6-7 syllables per second, speech perception and understanding involves rapid identification of speech sounds and pre-activation of morphemes and words. Using event-related potentials (ERPs) and functional magnetic resonance imaging (fMRI), we investigated the time-course and neural sources of pre-activation of word endings as participants heard the beginning of unfolding words. ERPs showed a pre-activation negativity (PrAN) for word beginnings (first two segmental phonemes) with few possible completions. PrAN increased gradually as the number of possible completions of word onsets decreased and the lexical frequency of the completions increased. The early brain potential effect for few possible word completions was associated with a blood-oxygen-level-dependent (BOLD) contrast increase in Broca's area (pars opercularis of the left inferior frontal gyrus) and angular gyrus of the left parietal lobe. We suggest early involvement of the left prefrontal cortex in inhibiting irrelevant left parietal activation during lexical selection. The results further our understanding of the importance of Broca's area in rapid online pre-activation of words.

Are belief‐based justifications associated with metalinguistic awareness? A cross‐sectional study in school‐age children

AbstractPrevious research has consistently demonstrated that false‐belief (FB) understanding correlates with and predicts metalinguistic ability in preschoolers. Surprisingly, however, there is scant evidence on the question of whether this relation persists at later ages. The present cross‐sectional study sought to fill this gap by examining the association between FB understanding, belief‐based justifications and metalinguistic awareness. A sample of 150 children primary‐school children between 8 and 11 years of age were administered a test of receptive language, a second‐order theory‐of‐mind task and a comprehensive metalinguistic battery. The results of correlational and regression analyses showed that explicit metalinguistic awareness (in particular, performance in the Ambiguity and Phonemic Segmentation subtests) was significantly predicted by children's belief‐based responses to the justification question in the theory of mind task but only for children with small receptive vocabularies; in contrast, FB understanding made no independent contribution (either alone or in interaction with other measures). These findings complement and advance existing data by showing that, in school‐age children, the association between the 2 domains involves more mature, verbally explicit levels of FB understanding and metalinguistic awareness.Highlights We examined the relation between metalinguistic awareness and theory‐of‐mind in primary‐school children. Metalinguistic awareness was associated to belief‐based justifications, but only for children with small vocabulary. In school‐age children the ability to provide verbal justifications plays a key role in the relation between theory‐of‐mind and metalinguistic awareness.

Vowel Deletion and Insertion in Úwù

Úwù is one of the many endangered languages in Nigeria.The number of its fluent speakers is believed to be less than 2000.The language is spoken in a small community known as Àyèré in Ìjùmú Local Government Area (LGA) of Kogi state. This paper describes the manifestation of vowel deletion and insertion in the language with the view of testing earlier assertions on the nature of vowel deletion and insertion in languages that are genetically related to Úwù. Apart from this, the paper is also an attempt to document these phonological phenomena (i.e. vowel deletion and insertion) before the language goes into extinction. About six hundred (600) lexical items of Úwù were collected for this research work with the aid of the 1000 word-list of the Summer Institute of Linguistics. Both linear and non-linear models were adopted for analysis in this research work. Cases involving segmental phonemes were analyzed with the linear phonology, while cases of feature stability and feature spread wereanalyzed using the non-linear model. The paper, among other things, reveals that the pattern of vowel deletion is predictable in Úwù, auto-segments like tone (mostly high tone), nasality and labial or round features usually persist even when the vowel which bore them was deleted. Apart from this, the paper also reveals that [i] is the epenthetic vowel in Úwù, and lastly, it is argued in the paper that nouns in Úwù are virtually vowel initial.

Examining the impact of the ABRACADABRA (ABRA) web-based literacy program on primary school students in Hong Kong

The current paper examined the effects of A Balanced Reading Approach for Children Always Designed to Achieve Best Results for All (ABRA), a web-based literacy programme developed by the the Centre for the Study of Learning and Performance (CSLP) at Concordia University, on primary school children in Hong Kong. The participants were 249 Primary 1 students from two low social economic status schools in Hong Kong and the two schools were well-matched on many demographic characteristics. All participating students were pre-tested in the fall and post-tested in the following spring. After adjusting for pretest differences, the treatment school scored significantly higher than the controls on three of the six outcome measures at post-tests: phoneme-grapheme correspondence (ES = +0.22, p < 0.05), phoneme segmentation (ES = +0.46, p < 0.00), and nonsense word fluency (ES = +0.22, p < 0.06). Both treatment and control students scored similarly on word reading, listening comprehension, and initial sound fluency. The outcomes of the study provides some promising evidence of the effects of ABRA on Chinese primary students in Hong Kong, especially on the enhancement of phonological skills, thus leading to early success in the formative years of learning English as a Second Language (ESL). Practical implications are discussed.

THE ERRORS OF SEGMENTAL PHONEMES AMONG LIBYANS ENGLISH STUDENTS STUDYING IN SEMARANG CITY, INDONESIA

This study attempts to investigate the errors of segmental phonemes that Libyan English students have when they pronounce English sounds. The participants in the study were fifteen, three females and the rest males, who study in Semarang city, Indonesia, and they were form different majors of master and Doctoral degrees (information system, public health, economic and bio-medic) at Semarang State University and Diponegoro University. The participants have never been to any of the English speaking countries, so they do not have any kind of exposure to a native English environment. The data was collected by two methods; recording test, in order to identify and evaluate the segmental errors, and questionnaire, in order to obtain participants’ perceptions about the expected errors, the reasons behind these errors and how to cope with them. The results showed that the Libyan speakers in this study had errors while they produce consonant clusters and certain English sounds, such as: consonants” /p/ , /v/ , /θ/ , /ð/ , /tʃ/ , /dʒ/ and /ŋ/”, vowels “ /ә/ , /ɛ:/ , /i:/ , /ɑ:/ , /u:/ , /ᴐ:/ and /ɪ/”, and finally diphthongs “/eә/ , /ʊә/ , /әʊ/.” This study also provides some helpful suggestions and recommendation that will reduce future errors regarding English segmental phonemes among Libyan English learners.

Sources of Phoneme Errors in Repetition: Perseverative, Neologistic, and Lesion Patterns in Jargon Aphasia.

This study examined patterns of neologistic and perseverative errors during word repetition in fluent Jargon aphasia. The principal hypotheses accounting for Jargon production indicate that poor activation of a target stimulus leads to weakly activated target phoneme segments, which are outcompeted at the phonological encoding level. Voxel-lesion symptom mapping studies of word repetition errors suggest a breakdown in the translation from auditory-phonological analysis to motor activation. Behavioral analyses of repetition data were used to analyse the target relatedness (Phonological Overlap Index: POI) of neologistic errors and patterns of perseveration in 25 individuals with Jargon aphasia. Lesion-symptom analyses explored the relationship between neurological damage and jargon repetition in a group of 38 aphasia participants. Behavioral results showed that neologisms produced by 23 jargon individuals contained greater degrees of target lexico-phonological information than predicted by chance and that neologistic and perseverative production were closely associated. A significant relationship between jargon production and lesions to temporoparietal regions was identified. Region of interest regression analyses suggested that damage to the posterior superior temporal gyrus and superior temporal sulcus in combination was best predictive of a Jargon aphasia profile. Taken together, these results suggest that poor phonological encoding, secondary to impairment in sensory-motor integration, alongside impairments in self-monitoring result in jargon repetition. Insights for clinical management and future directions are discussed.

Phonological awareness errors mirror underlying phonological representations: Evidence from Hebrew L1 – English L2 adults

This article examines the effect of phonological context (singleton vs. clustered consonants) on full phoneme segmentation in Hebrew first language (L1) and in English second language (L2) among typically reading adults (TR) and adults with reading disability (RD) ( n = 30 per group), using quantitative analysis and a fine-grained analysis of errors. In line with earlier findings, overall mean scores revealed significant differences between the two groups. However, no qualitative differences were found. In both groups and languages, full phoneme segmentation overall scores for CVC stimuli were higher than CCVC stimuli. This finding does not align with previous findings, obtained from a phoneme isolation task, showing that isolation from a cohesive CV unit is the most difficult. A fine-grained analysis of errors was conducted to glean insight into this finding. The analysis revealed a preference for creating and preserving CV units in phoneme segmentation in both L1 and L2. This is argued to support the cohesion of the CV unit. The article argues that the effect of language-specific sub-syllabic representations on phonemic analysis may not be always observed in overall scores, yet it is reflected in specific patterns of phonological segmentation errors.

Unsupervised Phoneme Segmentation Based on Main Energy Change for Arabic Speech

In this paper, a new method for segmenting speech at the phoneme level is presented. For this purpose, author uses the short-time Fourier transform of the speech signal. The goal is to identify the locations of main energy changes in frequency over time, which can be described as phoneme boundaries. A frequency range analysis and search for energy changes in individual area is applied to obtain further precision to identify speech segments that carry out vowel and consonant segment confined in small number of narrow spectral areas. This method merely utilizes the power spectrum of the signal for segmentation. There is no need for any adaptation of the parameters or training for different speakers in advance. In addition, no transcript information, neither any prior linguistic knowledge about the phonemes is needed, or voiced/unvoiced decision making is required. Segmentation results with proposed method have been compared with a manual segmentation, and compared with three same kinds of segmentation methods. These results show that 81% of the boundaries are successfully identified. This research aims to improve the acoustic parameters for all the processing systems of the Arab speech.

First-Grade Spelling Scores Within the Dynamic Indicators of Basic Early Literacy Skills (DIBELS) Screening: An Exploratory Study

ABSTRACTThe purpose of this study was to examine the validity evidence of first-grade spelling scores from a standardized test of nonsense word spellings and their potential value within universal literacy screening. Spelling scores from the Test of Phonological Awareness: Second Edition PLUS for 47 first-grade children were scored using a standardized procedure and an alternative invented spelling procedure. Correlations were examined among spelling and diagnostic word reading and decoding scores, along with scores from the Dynamic Indicators of Basic Early Literacy Skills (DIBELS). Spelling scores were significantly correlated with word reading and decoding scores, as well as DIBELS scores, except Phoneme Segmentation Fluency. Hierarchical multiple regression analyses revealed that spelling scores reliably accounted for significant variance in decoding but not word reading scores, beyond DIBELS scores. Implications are discussed related to the potential value of including early spelling scores within universal literacy screening.

Advancing Stage 2 Research on Measures for Monitoring Kindergarten Reading Progress

Although several measures exist for frequently monitoring early reading progress, little research has specifically investigated their technical properties when administered on a frequent basis with kindergarten students. In this study, kindergarten students (N = 137) of whom the majority was receiving supplemental intervention for reading skills were monitored using Letter Sound Fluency, Phoneme Segmentation Fluency, Word Reading Fluency, Nonsense Word Fluency, Highly Decodable Passages, and Spelling on a biweekly basis between February and May. Acceptable reliability was observed for all measures. Analyses of slope validity using latent growth models, latent change score models, and slope differences according to level of year-end achievement indicated that the relation of slope to overall reading skills varied across the measures. A suggested approach to kindergarten students’ reading progress is offered that includes Letter Sound Fluency and a measure of word-reading skills to provide a comprehensive picture of student growth toward important year-end reading outcomes.

Three DIBELS Tasks vs. Three Informal Reading/Spelling Tasks: A Comparison of Predictive Validity

Within a developmental framework, this study compared the predictive validity of three DIBELS tasks (phoneme segmentation fluency [PSF], nonsense word fluency [NWF], and oral reading fluency [ORF]) with that of three alternative tasks drawn from the field of reading (phonemic spelling [phSPEL], word recognition-timed [WR-t], and graded passage reading [grPASS), an oral reading fluency measure). Two cohorts of students (n = 319) were assessed with the aforementioned tasks multiple times across a four-year period—middle of kindergarten through end of third grade. The results were clear and closely replicated in the two cohorts: (a) phSPEL (moderate) outperformed DIBELS PSF (weak to moderate) in predicting future orthographic-unit processing; (b) WR-t (very strong) outperformed DIBELS NWF (moderate) in predicting future oral reading fluency; and (c) DIBELS ORF and grPASS were equally good predictors (moderately strong) of future reading comprehension.
