Intervention for a visual attention span processing deficit in a Greek-speaking child with slow reading speed:Developmental dyslexia and visual attention span processing training

We present the case of TN, aged 9;11, a monolingual Greek-speaking girl with accurate but slow word and non-word reading. Neuropsychological assessment revealed a selective deficit in visual attention (VA) span tasks.  TN had previously taken part in a spelling intervention targeting whole word processing and, although her spelling improved, at the end of the programme her reading remained slow. In the present study, we assessed TN in a lexical decision task with semantic primes, and she showed reduced semantic priming in relation to typically developing readers. TN took part in an intervention aimed at mitigating the VA span processing deficit and similar to a programme previously conducted with a twelve-year-old Greek-speaking boy, RF ([author(s)], 2013). Post-test results for TN revealed a significant improvement in letter report ability as well a reduction in word reading latencies; semantic facilitation was also observed in the priming task following the intervention, although differences were not significant. The results indicate, in line with previous research, an association between visual attention span and reading speed

Intervention for a multi-character processing deficit in a Greek-speaking child with surface dyslexia

A case study with a 12-year-old boy, R.F., who was a monolingual speaker of Greek is reported. R.F. showed slow word reading and a difficulty in spelling irregular words but not nonwords. Assessments revealed that R.F. did not appear to have a phonological deficit, but indicated impaired multicharacter processing ability for visually presented letter arrays. On the basis of previous research linking multicharacter processing and reading we developed an intervention aimed at improving R.F.'s ability to report letter arrays of increasing length. Following a 9-week programme, improvement was observed, and investigation of R.F.'s reading revealed gains in single word reading speed and accuracy. The findings support the significance of intervention studies for testing hypotheses regarding causal relationships among cognitive processes and the notion of specific profiles of developmental dyslexia/dysgraphia in both opaque and transparent orthographies

Effects of orthographic forms on the acquisition of novel spoken words in a second language

The orthographic forms of words (spellings) can affect word production in speakers of second languages. This study tested whether presenting orthographic forms during L2 word learning can lead speakers to learn non-nativelike phonological forms of L2 words, as reflected in production and metalinguistic awareness. Italian(L1) learners of English as a Second Language (English(L2)) were exposed to English(L2) novel spoken words (pseudowords) and real words in association with pictures either from auditory input only (Phonology group), or from both auditory and orthographic input (Phonology & Orthography group, both groups n = 24). Pseudowords and words were designed to obtain 30 semi-minimal pairs, each consisting of a word and a pseudoword that contained the same target consonant, spelled with one letter or with double letters. In Italian double consonant letters represent a long consonant, whereas the English language does not contrast short and long consonants. After the learning phase, participants performed a production task (picture naming), a metalinguistic awareness task (rhyme judgment) and a spelling task. Results showed that the Phonology & Orthography group produced the same consonant as longer in double-letter than in single-letter lexical items, while this was not the case for the Phonology group. The former group also rejected spoken rhymes that contained the same consonant spelled with a single letter in one word and double letters in the other, because they considered these as two different phonological categories. Finally, the Phonology & Orthography group learned more novel words than the Phonology group, showing that orthographic input results in more word learning, in line with previous findings from native speakers

The efficacy of grapheme-phoneme correspondence instruction in reducing the effect of orthographic forms on second language phonology

The orthographic forms (spellings) of second language (L2) words and sounds affect the pronunciation and awareness of L2 sounds, even after lengthy naturalistic exposure. This study investigated whether instruction could reduce the effects of English orthographic forms on Italian native speakers' pronunciation and awareness of L2 English sounds. Italians perceive, produce, and judge the same sound as a short sound if it is spelled with one letter and as a long sound if it is spelled with a digraph, due to L1 Italian grapheme-phoneme correspondence (GPC) rules whereby double consonant letters represent long consonants. Totally, 100 Italian learners of English were allocated to two conditions (final n = 88). The participants in the explicit GPC (EGPC) condition discovered English GPC rules relating to sound length through reflection, explicit teaching, and practice; the participants in the passive exposure condition practiced the same words as the EGPC participants, but with no mention of GPCs. Pre- and postintervention production (delayed word repetition) and phonological awareness (rhyme judgment) tasks revealed no positive effects of the instruction. GPC instruction appears to be ineffective in reducing orthographic effects on L2 phonology. Orthographic effects may be impervious to change, whether by naturalistic exposure or by instruction

Intervention for a lexical reading and spelling difficulty in two Greek-speaking primary age children

An intervention study was carried out with two nine-year-old Greek-speaking dyslexic children. Both children were slow in reading single words and text and had difficulty in spelling irregularly spelled words. One child was also poor in non-word reading. Intervention focused on spelling in a whole-word training using a flashcard technique that had previously been found to be effective with English-speaking children. Post-intervention assessments conducted immediately at the end of the intervention, one month later and then five months later showed a significant improvement in spelling of treated words that was sustained over time. In addition, both children showed generalisation of improvement to untrained words and an increase in scores in a standardised spelling assessment. The findings support the effectiveness of theoretically based targeted intervention for literacy difficulties

A linguistic awareness intervention targeting spelling and written expression in a 10-year-old dyslexic child

We report the case of a monolingual English-speaking boy (AM) aged 10-years, and the intervention targeting spelling and written expression difficulties that AM had. AM’s performance was contrasted in all experimental measures to a group of 13 typically developing spellers attending the same class. Literacy and cognitive assessments revealed for AM non-word reading difficulties, and deficits in spelling, written expression, phonological ability, verbal memory and rapid automatized naming. AM took part in nine sessions of linguistic awareness intervention that focused on promoting simultaneous attention to phonology, orthography, morphology, semantics and syntax. Results revealed a significant improvement in spelling, non-word reading, writing and handwriting. The results indicate that raising linguistic awareness can have a robust impact on spelling and written expression

AM’s performance was contrasted in all experimental measures to a group of 13 typically developing spellers attending the same class.

AM took part in nine sessions of linguistic awareness intervention that focused on promoting simultaneous attention to phonology, orthography, morphology, semantics and syntax. Results revealed a substantial improvement in spelling, pseudowordreading, writing and handwriting.
