When readers are asked to detect a target letter while reading for comprehension, they miss it more frequently when it is embedded in a frequent function word than in a less frequent content word. This missing-letter effect has been used to investigate the cognitive processes involved in reading. A similar effect, called the missing-phoneme effect…

While children are able to name letters fairly quickly, the automatisation of letter-speech sound mappings continues over the first years of reading development. In the current longitudinal fMRI study, we explored developmental changes in cortical responses to letters and speech sounds across 3 yearly measurements in a sample of 18 8-11 year old…

Previous studies have yielded contradictory results on the relationship between perception and production in second language (L2) phonological processing. We re-examine the relationship between the two modalities both within and across processing levels, addressing several issues regarding methodology and statistical analyses. We focus on the…

Diffusion tensor imaging tractography is a structural magnetic resonance imaging technique allowing reconstruction and assessment of the integrity of three dimensional white matter tracts, as indexed by their fractional anisotropy. It is assumed that the left arcuate fasciculus plays a crucial role for reading development, as it connects two…

Event Related Potentials (ERPs) were recorded from Spanish-English bilinguals (N = 10) to test pre-attentive speech discrimination in two language contexts. ERPs were recorded while participants silently read magazines in English or Spanish. Two speech contrast conditions were recorded in each language context. In the "phonemic in English"…

The auditory reassembly ability of 160 children drawn from the total third- and fifth-grade populations of three public elementary schools was investigated as a function of grade level and reading ability. The stimuli were temporally segmented consonant-vowel-consonant monosyllables with interphonemic intervals of 100, 200, 300, and 400…

Synthesizing a diverse group of studies, author argues that reading disability is not a unitary phenomenon but can result from deficiencies in different psychological processes. Based on the points at which an individual's reading breaks down, she presents a fourfold classifications scheme capable of categorizing all poor readers. (Editor/RK)

Describes three experiments that examined the processing of speech by dyslexic readers. Compares their performance with that of age-matched and reading-ability-matched controls. Shows that dyslexics have difficulty with the nonlexical procedures involved in verbal repetition. (HOD)

The vast majority of work on the processing characteristics of poor readers has been conducted with readers of English. In this article we report on results that outline the processing characteristics of poor readers of the Korean alphabetic-syllabic script, "Hangul." Three groups of readers (10 good readers, 10 poor readers and 9 poor readers…
