Impaired stress awareness in Spanish children with developmental dyslexia.
Spanish kids with dyslexia can’t feel syllable stress even in fake words, so slip prosody drills into every reading lesson.
01Research in Context
What this study did
Jiménez-Fernández et al. (2015) compared Spanish kids with dyslexia to same-age readers without dyslexia.
Each child listened to two-syllable made-up words. The kids had to pick which syllable carried the stress.
The task used nonsense words so no one could rely on vocabulary.
What they found
The dyslexia group missed twice as many stress beats as the control group.
Even after the researchers removed the effect of basic sound skills, the stress gap stayed large.
How this fits with other research
Early et al. (2012) looked at Greek kids and found no link between beat perception and reading. The two studies seem to clash, but Greek has very clear syllable rules while Spanish stress moves around. The tasks also differ: C tested simple beat tapping; Gracia tested syllable stress inside words.
Steinbrink et al. (2014) and Wang et al. (2019) show similar low-level sound problems in German and Chinese readers. Together these papers build a map: dyslexia can show up as weak stress, vowel, or tone skills, depending on the language.
Why it matters
If a child can’t hear where the punch falls inside a word, phonics drills alone may fail. Add quick daily prosody games: clap the stressed beat, stretch the loud syllable, or march while reading aloud. Two minutes can tighten the sound-print link and boost decoding fluency.

03Original abstract
The role of segmental phonology in developmental dyslexia (DD) is well established (e.g., deficit in phonological awareness), but the role of suprasegmental phonology (prosody) has been less widely investigated. Stress is one of the main prosodic features and refers to the relative prominence of syllables (strong/weak) within a word. The aim of the present study is to examine stress awareness in children with dyslexia and the possible mediation of phonemic awareness on suprasegmental phonological skills. Thirty-one Spanish children with DD and 31 chronological age-control children participated. Two stress awareness tasks were administrated, one with words and another with pseudowords. Results show that the children with dyslexia performed more poorly on both tasks than control children. The pattern of results in accuracy and reaction time suggest that, while children without difficulties use different strategies depending on the type of item, the children with dyslexia employ the same strategy to resolve the two tasks without any benefit of lexical knowledge about stress. Even so, this strategy did not work so efficiently as it did in the control group, which led the group with dyslexia to make a greater number of mistakes. It was also found that, when phonemic awareness was entered as a covariate, accuracy differences disappeared, but only in the word stress task. However, when lexical knowledge was not necessary (as in the pseudoword stress task) differences still remained statistically significant. Implications on the importance of suprasegmental processing in reading acquisition disabilities are discussed.
