The Categorical Perception Deficit in Dyslexia: A Meta-Analysis

The relationship between maternal education and the neural substrates of phoneme perception in children: Interactions between socioeconomic status and proficiency level

“…The ability to disregard phonemically irrelevant acoustic variability is necessary in order to recognize a wide variety of physically different sounds as exemplars of the same phoneme, which is important given that repeated utterances of the same phoneme vary acoustically both within and across speakers. CP of native phonemes is an important component of language development, as evidenced by the strong relationship between infant phoneme perception and later language abilities (Kuhl et al, 2008), as well as findings implicating CP deficits in at least some cases of specific language impairment (Joanisse & Seidenberg, 1998; Ziegler, Pech-Georgel, George, & Lorenzi, 2011) and dyslexia (Noordenbos & Serniclaes, 2015). This ability continues to develop between the ages of 6 and 12 years, with performance still not reaching adult levels at the upper end of this age range (Bogliotti, 2003; Elliott, Longinotti, Meyer, Raz, & Zucker, 1981; Hazan & Barrett, 2000).…”

Teorias da Dislexia: Sustentação com Base nas Alterações Perceptuais Auditivas

“…Noordenbos and Serniclaes (2015) speculate that the reorganization of phonological representation does not happen to the same extension in dyslexic individuals for genetic reasons and the allophonic speech perception is one of the likely causes of dyslexia. For the authors, the allophonic perception does not allow the correct establishment of graphophonic relations even in perfectly transparent alphabetical systems, causing an important disturbance of the written language development.…”

“…This theory was developed based on evidence that dyslexic individuals present change on speech perception (Noordenbos & Serniclaes, 2015). The phonemic representation is the final product of a development process that has two important stages: the integration of universal allophonic characteristics into specific phonological characteristics of the language that happens when the individual is around one year old, and the combination of phonological characteristics into phonemic segments, which happens between 5 and 6 years old (Hoonhorst et al, 2011).…”

“…Dyslexic individuals present deficit in phonemic discrimination and categorical perception of speech sounds (Boets et al 2011;Bogliotti et al, 2008;Noordenbos & Serniclaes, 2015;Prestes, 2016;Serniclaes et al, 2004;Vandermosten et al, 2010). Categorical perception can be defined (Elangovan & Stuart, 2008) as abrupt change from the perception of a phonemic category to another in a given time along a continuum.…”

“…are only differentiated by the sonority trait (Noordenbos & Serniclaes, 2015). The discrimination during the production of speech of these pairs of phonemes cannot resort to visual cues, since these pairs are visually similar in topography of articulation.…”
