ABSTRACT A group of 19 children with dyslexia aged 7 years 2 months to 10 years 9 months were selected from a clinical sample and tested using a large neuropsychological battery in order to specify the severity and subtype of dyslexia as well as the presence of comorbid conditions. Thereafter, they received a standardised training of 6 weeks of daily auditory exercises aimed at reinforcing explicit and implicit phonological awareness. Ten participants also received specific training of the sensory-motor aspects of articulatory production of individual phonemes during the first 3 weeks of auditory training, whereas the remaining received the same specific training during the last 3 weeks of auditory training. Repetition, phonological awareness, reading and spelling were assessed before the first session, between the two sessions and after the second session. Results confirm the overall efficiency of intensive phonological training, even with exclusively auditory material. The main outcome of this study is a significant improvement of phonology and non-word reading specifically during the periods where the two methods were associated, suggesting a significant contribution of articulatory training to the observed improvement. Finally performance to a motor tapping task proved to be one of the best predictors of training efficiency while comorbid co-ordination or attention deficit did not interfere. Results are interpreted with reference to current theories about mechanisms underlying dyslexia.

    ABSTRACT: This research defines a ‘Social Reader’ aimed to helpreading by dyslexia patients. Social Reader is capable of creating a socialized reading environment, whereindividuals with dyslexia can seek help from volunteersand other readers while reading e-Books, papers, andnovels. The help can include an explanation of anequation, a page, or a whole chapter. By implementingthe dynamic help between volunteers and readers or justamong the readers, a vivid reading community can beestablished. This well-structured reading community isassumed to help individuals with dyslexia improve theircognitive performance while simultaneously building uptheir self-esteem and self-confidence as they interactwith other individuals with dyslexia. Having low self-esteem is known to severely affect reading, writing, andorganizational skills as well as overall life satisfactionfor individuals with dyslexia. The research focuses on three usability engineeringmethods that assisted in our design. The first method,sensitive persona, captures the empathy of the targetuser’s persona; it can foster the designer’s desire todesign high quality products for end-users. The secondmethod, persona self-guided evaluation, brings theapplication of persona in user centered design not onlyto design but to evaluation, in order to minimize the gapbetween target users and evaluators when two differentgroups are employed. The third method, persona think-aloud evaluation, enhances the traditional think-aloudmethod for user-centered evaluation.By designing Social Reader, design team membersundertook a complete human-centered product designand evaluation life-cycle, including contextual inquiryand analysis, persona creation, wireframe creation, andprototype creation. In each phase of the design process,the concept of a persona was extensively used; inparticular, our persona-based evaluation duringwireframe and prototype creation.In designing the Social Reader for individuals withdyslexia, the design team identified sensitive personacentered design and evaluation, connecting it with thegoals of Kansei and with affective design. An expertevaluation by usability engineers gained a goodprojected acceptance for individuals with dyslexia.

    ABSTRACT: Research Findings: In this study, 88 kindergartners received special training in lexical compounding, homophone awareness, or phonological awareness or were assigned to a control condition over a period of approximately 2 months, with 20-min lessons administered twice per week. Chinese word reading improved significantly more in the lexical compounding group as compared to the other groups. Vocabulary knowledge also showed a trend toward improvement in this group (p

    ABSTRACT: A group of children with dyslexia (mean ages 9 and 14 years) was studied, together with group of children without dyslexia matched for age. Participants were monolingual native speakers of the Bosnian language with transparent orthography. In total, the diagnostic tests were performed with 41 children with dyslexia and 41 nondyslexic children. The participants were asked to produce monosyllables, /pa/, /ta/, and /ka/, and the trisyllable /pataka/, as fast as possible. Analysis was undertaken in four ways: (1) time of occlusion duration for plosives (duration of stop), (2) voice onset time for plosives, (3) diadochokinetic rate-articulators rate measured by pronunciation of monosyllables and the trisyllable, and (4) time of moving articulators from one gesture to another-time of interval length (from the explosion of one plosive to the start of the explosion of another plosive). The results suggest that children with dyslexia have significant problems with the speed of articulatory movements involved in speech production.
