Dissertation dish: Does music perception predict phonological awareness

The role of music perception in predicting phonological awareness in five- and six-year-old children by Lathroum, Linda M., Ph.D., University of Miami, 2011 , 130 pages; AAT 3491105

Abstract

The purpose of this study was to examine the role of music perception in predicting phonological awareness in five- and six-year-old children. This study was based on the hypothesis that music perception and phonological awareness appear to have parallel auditory perceptual mechanisms. Previous research investigating the relationship between these constructs--music perception and phonological awareness--has been promising, but inconclusive. Phonological awareness is an important component of early literacy which many children struggle to acquire. If the constructs are shown to be related, music-based interventions may then be developed to promote phonological awareness, thus enhancing early literacy.

Music perception, phonological awareness, and visual-spatial skills of 119 five- and six-year-old children were tested. The researcher administered the Children's Music Aptitude Test (Stevens, 1987) in order to assess perception of pitch, rhythm, and melody. Subsequently, the Comprehensive Test of Phonological Processing (Wagner, Torgesen, & Rashotte, 1999) was administered in order to measure phonological awareness skills, including blending, elision, and sound matching. The Visual Spatial Relations subtest of the Woodcock Johnson III (Woodcock, McGrew, & Mather, 2001) was later used to assess visual spatial skills.

Structural equation modeling (SEM) allowed the researcher to model relationships between the latent variables to investigate the contribution of music perception, visual-spatial skills, and age to phonological awareness. Results supported the hypothesis that music perception, visual spatial skills, and age predict phonological awareness.

Additionally, music perception made a statistically significant contribution to phonological awareness, when controlling for visual spatial skills and age. Specifically, music perception predicted a larger amount of standardized unit change in phonological awareness than did the other predictors in the theory. Thus, music perception appears to have a stronger relationship with phonological awareness than age or visual spatial skills.

Further, results showed that a model without music perception as a predictor of phonological awareness was not supported. These findings confirm that music perception plays a unique role in predicting phonological awareness, above and beyond the contribution made by visual spatial skills and age. This study's results could be used in support of the development of music-based interventions for promoting phonological awareness in five- and six-year-old children.

Dissertation Dish: Can pitch or rhythm (Ga-auditory processing) training improve phonological awareness (Ga)

The effectiveness of Separate Pitch and Rhythm Training Interventions on the Phonological Awareness of Kindergarten Learners by Richards, Susannah Converse, Ed.D., Northcentral University, 2011 , 171 pages; AAT 3472255

Abstract

Although neuroscientists assert that music training impacts neural development, previous research has not teased apart which components of music possibly enhance language literacy in emergent readers. The purpose of this quantitative research study was to establish if immersion in pitch activities as compared with rhythm activities could cause the significant development of initial sound (IS) skills, letter sounds (LS) skills, and sound pattern skills in kindergarten readers. This study examined the effectiveness of supplemental music instruction on the phonological awareness skills of kindergarten learners ( N = 38) who originated from seven classrooms in one suburban elementary school. Leveled subjects randomly were assigned to an experimental pitch group ( n = 12), or an experimental rhythm group ( n = 11), or a control group ( n = 15). During sixteen 40-minute sessions that spanned eight weeks, pitch group subjects explored the highness and lowness of sound, while rhythm group subjects investigated the duration of sound. The control group engaged in 20-minute weekly read-aloud sessions. Pre- and post-test data collection consisted of the kindergarten version of the Test of Phonological Awareness - Second Edition: Plus , and the sound patterns music subtest of the Woodcock Johnson III . Data was converted to Statistical Package for the Social Sciences (SPSS) for analysis. Separate 3 x 3 factorial Analysis of Variance (ANOVA) revealed the levels differed on each of the IS variables (pitch [ F =7.74; df = 3], rhythm [ F = .07; df = 3], control [ F = .18; df = 2]); and the LS variables (low pitch [ F = 1.0; df = 3], low rhythm [ F = 6.62; df = 3], low control [ F = 4.0; df = 2]). Significance was observed with a matched-pairs t -test with the low pitch treatment group ( t [3] = 0.034, p < 0.04). Future research should recruit a larger sample and utilize a different music assessment. This study provides insight into a real-world application relative to specific components of music that potentially enhance the phonological awareness of the most challenged of kindergarten readers before remediation is necessary.

Dissertation dish: Temporal processing and early reading development

An interesting unpublished dissertation that highlights the relationship between temporal processing (click here for link to relevant portion of IQ Brain Clock EWOK; click here for other "temporal processing" posts at this blog; click here for other "reading" and timing posts at this blog) and early reading development. PDF copy can be downloaded from the original cite (click here). Thanks to Amy V. for forwarding me information about this dissertation. This is the first "dissertation dish" post at the IQ Brain Clock. Dissertation dish posts are a semi-regular feature at IQ's Corner.

As is often the case, this dissertation has a nice literature review on the role of auditory and temporal processing and reading, as well as the well-known role of phonological processing and reading. Of particular interest was the finding that temporal processing explained additional variance unique from phonological processing variance. That is - both temporal and phonological processing were found to be important sources in understanding early reading development.

Title	The Role of Temporal and Phonological Processing In Early Reading Development: A Longitudinal Study
Author	Hood, Michelle H
Institution	Griffith University
Date	2005
Abstract

• [Blogmaster note - bold font added by me] This study investigated the ability of auditory and visual temporal processing measured before school entry (mean age 5.36 years) to predict early reading development in an unselected sample of children. There were 142 children at the first phase (Preschool), 125 at the second phase 6 - 8 months later (early Grade 1; mean age 5.94 years), and 105 at the third phase12 months later (Grade 2; mean age 6.94 years). There were similar numbers of males and females. Visual and auditory temporal order judgement (TOJ) and Temporal Dot accuracy (rapid visual sequencing task) measured at Preschool explained a significant percentage of the variance in letter identification (an important pre-reading skill) measured concurrently. These measures also predicted a significant percentage of the variance in letter and word identification (word reading accuracy) and reading rate (fluency) measured in early Grade 1, even after controlling for the effects of age, environment, memory, attentional vigilance, non-verbal ability, and speech and language problems. They also significantly discriminated between groups of children at Grade 1 who could and could not use phonological decoding to read non-words. By Grade 2, these Preschool measures accounted for significant variance in word reading accuracy and fluency and in non-word decoding. Only Preschool auditory temporal processing accounted for significant unique variance in the reading measures at Preschool or Grade 1, but by Grade 2, visual temporal processing (Temporal Dot) also accounted for significant unique variance. Temporal Dot accuracy also explained unique variance in the rate of growth in these reading measures across this period.
• These changes in predictive ability by the auditory and visual temporal processing measures were interpreted as reflecting developmental changes in their roles in reading as reading develops. Auditory temporal processing was important in early pre-reading and reading and remained important throughout. Visual temporal processing only became important in the later phase, possibly because of increasing need to analyse letter sequences. Preschool temporal and phonological processing measures accounted for approximately equal percentages of variance in the reading measures at Preschool and Grade 1, but by Grade 2, the Preschool phonological processing measures accounted for significantly more variance in all reading measures, except Pseudohomophone Choice (orthographic processing). Very little of the variance that was explained in the reading measures was common to temporal and phonological processing. The variance that each uniquely explained in reading was more important than the variance they explained in common. Therefore, utilising both temporal and phonological processing predictors optimised prediction of early reading skills.
• The study also showed there was significant linear development occurring in temporal processing from Preschool to Grade 2. The correlations of scores on the temporal measures from Preschool to Grade 1 were moderate. The relative position of children within the distribution on these skills showed moderate stability over the short-term, but less stability over the long-term. The majority of children who fell in the bottom quartile on the temporal and phonological processing measures at Preschool remained in the bottom half of the distribution on those measures by Grade 2. These children may represent those who are at most risk for reading difficulties. Letter Word Identification showed high stability from Preschool to Grade 2.
• There was little difference in the percentage of variance explained in subsequent reading between temporal processing measures obtained at Preschool or Grade 1. However, performance on the Visual temporal order judgement task was more likely to account for significant unique variance in reading when measured after school entry than before. This was consistent with the expected developmental changes in reading. When measured after school-entry, phonological processing measures accounted for greater percentages of variance in the reading measures than when measured before. There were also developmental changes in which phonological processing measures were important predictors of reading skills. When measured at Grade 1, rhyme and alliteration detection and phonemic segmentation were the most important predictors. However, when measured at Grade 2, performance on the Rhyme and Alliteration task had reached ceiling, so would no longer be a useful predictor of later reading. These results were consistent with developmental models of reading and of phonological processing.
• The results provided support for a causal role of temporal processing in reading development. They also showed that measures of visual and auditory temporal processing obtained close to school-entry would be a useful addition to predicting risk of early reading difficulties. However, additional work is needed to determine the most suitable temporal processing measures for this younger age group.
