In recent weeks, Frontiers in Psychology published a meta-analysis by Gordon, Fehd and McCandliss (2015) which asked, ‘Does music training enhance literacy skills?’
The authors described a ‘rapidly accumulating body of evidence’ and listed studies that reported significant associations between musical training and language skills, such as Magne et al. (2006) and others which described enhanced brain responses via musical training to unexpected timing and duration of syllables (Chobert et al., 2011) and pronunciation (Milanov et al., 2009). They also reported significant correlations between musical aptitude (in the absence of musical training) and reading performance (Strait et al., 2011).
Gordon and colleagues also referred to a study in which ability in musical rhythm explained the variance in production of grammar in six year olds and complex sentence structures in a follow up (Gordon et al., 2015) and cited earlier studies of musical rhythm, in which an ability to synchronise with a beat predicted phonological awareness and rapid naming tasks (Woodruff Carr et al., 2014), second grade reading skills (Dellatolas et al., 2009) and better reading performance in adolescence (Tierney and Kraus, 2013).
Historically, scholars have made use of a wide range of literacy-related outcome measures and this proved something of a challenge for Gordon and her co-workers. Assessments of reading ability and phonological awareness have been designed to measure reading comprehension, reading rate, reading accuracy, reading fluency and a variety of phonological awareness related skills. Some measures control for working memory, while others do not. Assessments also vary in their formats. Some simply require an individual child to read a list of single words aloud, while others can be administered to groups of children, requiring them to read passages of connected text in silence. To some extent, direct comparisons of effect size can be made, but unless these are described in terms of their educational context, teachers cannot make informed decisions about the usefulness of rhythm-based approaches for different reading-related skills.
The use of random assignment in an educational setting putatively isolates the impact of an intervention under experimental rather than quasi-experimental conditions; yet no such experimental conditions exist in a school. Indeed the authors’ meta-analysis indicated that the amount of reading-related support given to children was rarely held constant over time. Moreover, the random assignment of individuals to any ‘treatment’ is known to induce positive or negative placebo effects, which can be sufficiently powerful to influence outcomes. In the context of a school, influential factors contributing to such effects typically include (i) compatibility of the individuals within the ‘treatment’ group, (ii) location of the ‘treatment’ in a room associated with a particular function in the school and (iii) timing of the ‘treatment’ to routinely coincide with particular social or academic activities.
All of the studies included by the authors in the meta-analysis have been peer reviewed. Relatively few studies had used the RCT paradigm, but all of the studies compared musical training against controls, and included before and after comparison measures and indicated that reading instruction had been held constant across groups. Out of 4855 publications obtained in searches between November 2013 and March 2014, only 13 studies fulfilled these requirements and were included in the meta-analysis.
Three of these studies were considered by the authors to be particularly highly powered because they controlled for IQ and SES; they obtained very large effect sizes. A study of the effect of musical training on word reading obtained an effect size of 1.07 (Moreno et al., 2009). Moritz et al., (2013) reported the effect of musical training on phonological skills (PAT rhyming discrimination), whereas Dege and Schwarzer (2011) showed the impact of musical training on phonological awareness (DEBELS). Both teams found large effect sizes of 1.20 and 0.78 respectively.
To inform future directions for studies of this type, Gordon and colleagues proposed that the following questions should be addressed. For further information about rhythm-based approaches to reading, click here.
1. “What are the effects of different components of interventions (rhythm, pitch; instruments vs. singing; phonological activities in musical context, etc.) on training efficacy?”
2. “What degree of music-driven gains in phonological awareness is needed to impact reading fluency?”
3. “What are the mechanisms underlying improvement: such as attention, motivation, (e.g., OPERA hypothesis; Patel, 2011), speech prosody sensitivity, and/or working memory?”
4. “How are changes in brain function and structure associated with music-training-driven improvements?”
5. “How do individual differences predict response to training? Is there a subset of children that stands to benefit the most from music training?”
