Auditory temporal perception, phonics, and reading disabilities in children

Impaired Speech Perception in Poor Readers: Evidence from Hearing and Speech Reading

“…Poor readers count as normal in on-line perception of spoken language, but a small number of studies have reported inferior perception of auditory verbal stimuli by poor readers (Brady, Poggie, & Merlo, 1986;Brady, Shankweiler, & Mann, 1983;de Weirdt, 1988;Godfrey, Syrdal-Laskey, Millay, & Knox. 1981;Lieberman, Meskill, Chatillon, & Schupack, 1985;Reed, 1989;Tallal, 1980;Werker & Tees, 1987). In a preliminary report of the data presented below we also found impairments in speech processing (de Gelder & Vroomen, 1988).…”

“…No reading-group differences were found in the recall of environmental sounds, but performance was significantly different with words presented in noise. In contrast with this specific focus on speech perception, Tallal (1980) argued that reading-backwardness involved difficulties in general auditory processing. She found that reading-disabled children were worse than normal children in making temporal order judgments for very brief nonspeech tones presented at short interstimulus intervals.…”

Motion and Form Coherence Detection in Autistic Spectrum Disorder: Relationship to Motor Control and 2:4 Digit Ratio

“…It seems probable that several different biological and neurological factors may contribute to the autistic syndrome; that is, it may have a heterogeneous etiology. Additionally, sensori-motor deficits have been reported in dyslexia (Fawcett et al, 1996;Livingstone et al, 1991;Lovegrove, Bowling, Badcock, & Blackwood, 1980;Tallal, 1980), and motion detection impairments have been reported in Williams syndrome (Atkinson et al, 1997). Ramus (2002) has proposed that sensori-motor impairments are not a core feature of dyslexia, but rather secondary features arising only in cases with excessive foetal testosterone.…”

Auditory attention to frequency and time: an analogy to visual local–global stimuli

“…These authors argued that many of the asymmetries in both audition and vision result from a preferred role for the left and right hemispheres in processing relatively high and low frequencies, respectively, in the senses of both pitch and spatial frequency. The hemispheric asymmetry within the dimension of time has been developed by many authors, including Ackermann and Riecker (2004), Allard and Scott (1975), Deacon (1997), Ivry and Robertson (1998, Chapter 6), Tallal (1980), and Zatorre, Belin, and Penhune, (2002). We shall refer to this idea as the Asymmetric Sampling in Time (AST) theory, the name ascribed to it by Poeppel (2003).…”
