'Unexpected' spelling difficulty in a ten-year-old child with good reading skills: An intervention case study

We report a single-case intervention study of Alan, a child aged 10;04, who presented with spelling difficulty but good reading skills. Assessment of the potential cognitive functions underlying the spelling difficulty explored phonological abilities, visual memory and letter report. We also assessed print exposure and verbal memory. Results of analysis of spelling performance revealed an effect of word length on accuracy, and spelling errors involving omission, insertion, substitution and transposition of graphemes. Results of the literacy-related assessments indicated that Alan did not have a phonological or visual memory deficit, but he showed impaired performance in the letter-report task when asked to report all the letters in the five-item test array. On the basis of previous research, we hypothesised that Alan’s unexpectedly poor spelling was due to a graphemic buffer deficit. Two different interventions were employed: a lexical-orthographic programme, followed by one aimed at improving sublexical abilities. The results showed a significant increase in spelling accuracy after the lexical-orthographic intervention for the treated word set, and a small improvement for the untrained words that was significant at delayed post-intervention testing. The improvement was shown to persist over time. No improvement in spelling was observed after the sublexical intervention. The study emphasises the importance of a wide assessment in order to investigate cognitive processes underpinning spelling difficulty

Differential perception of innovation with particular reference to the organisational context

Differential perception of innovation is a research area which has been advocated as a suitable topic for study in recent years. It developed from the problems encountered within earlier perception of innovation studies which sought to establish what characteristics of an innovation affected the ease of its adoption. While some success was achieved In relating perception of innovation to adoption behaviour, variability encountered Within groups expected - to fercelve innovation similarly suggested that the needs and experiences of the potential adopter were significantly affecting the research findings. Such analysis being supported by both sociological and psychological perceptual research. The present study sought to identify the presence of differential perception of innovation and explore the nature of the process. It was decided to base the research in an organisational context and to concentrate upon manufacturing innovation. It has been recognised that such adoption of technological innovation is commonly the product of a collective decision-making process, involving individuals from a variety of occupational backgrounds, both in terms of occupational speciality and level within the hierarchy. Such roles appeared likely to significantly influence perception of technological innovation, as gathered through an appropriate measure and were readily identifiable. Data vas collected by means of a face-to-face card presentation technique, a questionnaire and through case study material. Differential perception of innovation effects were apparent In the results, many similarities and differences of perception being related to the needs and experiences of the individuals studied. Phenomenological analysis, which recognises the total nature of experience in infiuencing behaviour, offered the best means of explaining the findings. It was also clear that the bureaucratic model of role definition was not applicable to the area studied, it seeming likely that such definitions are weaker under conditions of uncertainty, such as encountered in innovative decision-making

A sublexical training study for spelling in a biliterate Greek- and English- speaking child

RI is an emergent trilingual boy, literate in Greek and English, with difficulties in reading and spelling in both languages. Assessment with non-literacy tests revealed a deficit in phonological ability and in visual memory for sequentially presented characters. RI took part in a training programme that targeted sublexical spelling processes. Post-intervention assessment revealed improvement in reading and spelling in Greek but not in English. Assessments of lexical and sublexical skills showed improvement in nonword spelling and nonword reading for Greek. For English, there was some indication of improvement in nonword reading at delayed post-intervention testing, but no evidence of improvement in nonword spelling. Possible reasons for the difference in outcome for the two languages are considered, including the level of transparency of written Greek and English

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

Intervention for a visual attention span processing deficit in a Greek-speaking child with slow reading speed

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 span (VAS) 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 VAS processing deficit and similar to a programme previously conducted with a twelve- year-old Greek-speaking boy, RF (Niolaki & Masterson, 2013). Post-test results for TN revealed a significant improvement in letter report ability, as well as a reduction in word reading latencies; semantic facilitation was also observed in the priming task following the intervention, although pre- and post-intervention differences were not significant. The results indicate, in line with previous research, an association between visual attention span and reading speed
