Error patterns in word reading among primary school children: A cross-orthographic study

DYSLEXIA, Issue 1 2004
Louise Miller Guron
Abstract A comparative investigation of word reading efficiency indicates that different strategies may be used by English and Swedish early readers. In a first study, 328 native English speakers from UK Years 3 and 6 completed a pen-and-paper word recognition task (the Wordchains test). Results were analysed for frequency and type of errors committed. A sample of 123 chronological-age-matched Swedish children carried out the same task on a matched Swedish test. For a sub-sample of 68 English/Swedish pairs matched on word recognition score and sex, significant differences were observed in a comparison of average and low scorers from the two language groups. The English children attempted more task items and committed more errors, while the Swedish group corrected their errors more, suggesting a difference in approach to the task. A second study of a larger Swedish sample (241 participants) found the same pattern of errors as Study 1. The implications of these findings are discussed in relation to the effects of orthographic depth and morphemic complexity. Copyright © 2004 John Wiley & Sons, Ltd. [source]


rSNP_Guide: An integrated database-tools system for studying SNPs and site-directed mutations in transcription factor binding sites,

HUMAN MUTATION, Issue 4 2002
Julia V. Ponomarenko
Abstract Since the human genome was sequenced in draft, single nucleotide polymorphism (SNP) analysis has become one of the keynote fields of bioinformatics. We have developed an integrated database-tools system, rSNP_Guide (http://wwwmgs.bionet.nsc.ru/mgs/systems/rsnp/), devoted to prediction of transcription factor (TF) binding sites, alterations of which could be associated with disease phenotype. By inputting data on alterations in DNA sequence and in DNA binding pattern of an unknown TF, rSNP_Guide searches for a known TF with alterations in the recognition score calculated on the basis of TF site's sequence and consistent with the input alterations in DNA binding to the unknown TF. Our system has been tested on many relationships between known TF sites and diseases, as well as on site-directed mutagenesis data. Experimental verification of rSNP_Guide system was made on functionally important SNPs in human TDO2and mouse K-ras genes. Additional examples of analysis are reported involving variants in the human ,A-globin (HBG1), hsp70(HSPA1A), and Factor IX (F9) gene promoters. Hum Mutat 20:239,248, 2002. © 2002 Wiley-Liss, Inc.

Long-Term Hearing Results in Gamma Knife Radiosurgery for Acoustic Neuromas,

THE LARYNGOSCOPE, Issue 6 2008
Matthew L. Bush MD
Abstract Objectives: There are many studies that have examined functional outcomes following Gamma Knife treatment; however, few have reported long-term audiometric data. This study analyzed the long-term hearing results of Gamma Knife radiosurgery in the treatment of acoustic neuromas. Study Design: Retrospective cohort study. Methods: Seventeen patients were selected from our acoustic neuroma Gamma Knife registry of 113 patients treated from 1991 to 2005. Pretreatment audiograms were analyzed for pure-tone average and word recognition scores and assigned a Gardner-Robertson classification score (GRC). Either a current audiogram was obtained or the most recent audiogram (if the patient was lost to follow-up) was reviewed from clinic charts and these were compared with the preoperative results. Audiometric data of the pre- and posttreatment normal ear were obtained and used as the patient's own control. Results: The tumor size ranged from 0.5 to 2.8 cm (mean, 1.33 cm) and patients received a range of 12.5,16 Gy (mean, 13.82 Gy) to 50% isodose line. Patient follow-up ranged from 3 to 82 months with a mean of 33.6 months. Pretreatment pure-tone average for the involved side group was 30.6 dB HL with a word recognition score of 74%. Pretreatment mean GRC was 1.76. posttreatment pure-tone average for the group was 59.7 dB HL with a word recognition score of 37%. posttreatment mean GRC was 3.29. Comparing pre- versus post-Gamma Knife radiosurgery results on the treatment ear, means were statistically significantly different for both pure-tone average and word recognition scores, based on a paired-samples t test (P < .001 for both). The group "normal" ear pure-tone average was 14 dB HL and 17.75 dB HL pre- and posttreat-ment, respectively. Normal ear pre- and posttreatment word recognition score and GRC were 93% and 98%, and 1.13 and 1.31, respectively. Conclusion: Gamma Knife radiosurgery remains a noninvasive treatment option for patients with acoustic neuromas; however, they may experience a delayed hearing loss. Of those patients with useful audition pretreatment, 42% maintained useful hearing posttreatment. [source]


Shyness and emotion-processing skills in preschoolers: a 6-month longitudinal study

INFANT AND CHILD DEVELOPMENT, Issue 2 2008
Paul S. Strand
Abstract The present study utilized a short-term longitudinal research design to examine the hypothesis that shyness in preschoolers is differentially related to different aspects of emotion processing. Using teacher reports of shyness and performance measures of emotion processing, including (1) facial emotion recognition, (2) non-facial emotion recognition, and (3) emotional perspective-taking, we examined 337 Head Start attendees twice at a 24-week interval. Results revealed significant concurrent and longitudinal relationships between shyness and facial emotion recognition, and either minimal or non-existent relationships between shyness and the other aspects of emotion processing. Correlational analyses of concurrent assessments revealed that shyness predicted poorer facial emotion recognition scores for negative emotions (sad, angry, and afraid), but not a positive emotion (happy). Analyses of change over time, on the other hand, revealed that shyness predicted change in facial emotion recognition scores for all four measured emotions. Facial emotion recognition scores did not predict changes in shyness. Results are discussed with respect to expanding the scope of research on shyness and emotion processing to include time-dependent studies that allow for the specification of developmental processes.

Audiological Application Criteria for Implantable Hearing Aid Devices: A Clinical Experience at the Nijmegen ORL Clinic,

THE LARYNGOSCOPE, Issue 9 2008
Veronique J. O. Verhaegen MD
Abstract Objectives/Hypothesis: To define audiological application criteria for different implantable hearing aid devices. Study Design: Retrospective study. Methods: Comparisons were made between aided speech recognition scores obtained at conversational level (65 dB) in patients with the Vibrant Soundbridge (VSB) (n = 22), the Otologics middle ear transducer (MET) (n = 10), conventional hearing aids (behind-the-ears) (n = 47), and cochlear implants (CIs) (n = 123). Results: In relation to hearing loss, only for mild hearing loss, speech recognition scores with VSB were comparable to that with conventional hearing aids. In the Otologics MET users, speech recognition scores were comparable with those of the conventional hearing aid users until a mean hearing loss of about 75 dB HL. At a sensorineural hearing loss of about 65 dB HL or more, the Otologics MET users have better speech recognition scores than the VSB users. For comparison with CI users, we followed a more conservative approach. In 90% of the users of a CI, speech recognition scores were better than those in: 1) patients with a conventional hearing aid and a mean hearing loss of about 95 dB HL or worse; 2) patients with an Otologics MET and a mean hearing loss of 85 dB HL or worse. Conclusions: Patients fitted with a VSB or an Otologics MET middle ear implant do not demonstrate better speech recognition scores than patients fitted with today's conventional hearing aids. Results might even been worse. However, the VSB and Otologics MET are a good option in patients with moderate (VSB) to severe (Otologics MET) sensorineural hearing loss and external otitis.

Memory Binding in Early Childhood: Evidence for a Retrieval Deficit

CHILD DEVELOPMENT, Issue 5 2009
Marianne E. Lloyd
Previous research has suggested that performance for items requiring memory-binding processes improves between ages 4 and 6 (J. Sluzenski, N. Newcombe, & S. L. Kovacs, 2006). The present study suggests that much of this improvement is due to retrieval, as opposed to encoding, deficits for 4-year-olds. Four- and 6-year-old children (N = 48 per age) were given objects, backgrounds, and object + background combinations to remember. Younger children performed equivalently to 6-year-olds during a working memory task for all types of memory questions but were impaired during a long-term memory task for the object + background combinations. Furthermore, this deficit was completely due to differences in false alarm rates, suggesting that separate analyses of hits and false alarms may be preferable to corrected recognition scores when studying memory development.
