Ability of dyslexic and control teenagers to sustain attention and inhibit responses

Dyslexia and attentional difficulty have often been linked, but little is known of the nature of the supposed attentional disorder. The Sustained Attention to Response Task (SART: Robertson, Manly, Andrade, Baddeley and Yiend, 1997) was designed as a measure of sustained attention and requires the withholding of responses to rare (one in nine) targets. To investigate the nature of the attentional disorder in dyslexia, this paper reports two studies which examined the performance of teenagers with dyslexia and their age-matched controls on the SART, the squiggle SART (a modification of the SART using novel and unlabellable stimuli rather than digits) and the go-gap-stop test of response inhibition (GGST). Teenagers with dyslexia made significantly more errors than controls on the original SART, but not the squiggle SART. There were no group differences on the GGST. After controlling for speed of reaction time in a sequential multiple regression predicting SART false alarms, false alarms on the GGST accounted for up to 22% extra variance in the control groups (although less on the squiggle SART) but negligible amounts of variance in the dyslexic groups. We interpret the results as reflecting a stimulus recognition automaticity deficit in dyslexia, rather than a sustained attention deficit. Furthermore, results suggest that response inhibition is an important component of performance on the standard SART when stimuli are recognised automatically.

Lesbian, gay, bisexual and transgender psychology:an international conversation among researchers

This article reports on a conversation between 12 lesbian, gay, bisexual and transgender (LGBT) psychologists at the first international LGBT Psychology Summer Institute at the University of Michigan in August 2009. Participants discuss how their work in LGBT psychology is affected by national policy, funding and academic contexts and the transnational influence of the US-based stigma model of LGBT psychology. The challenges and possibilities posed by internationalism are discussed with reference to the dominance of the United States, the cultural limits of terms such as 'lesbian, gay, bisexual and transgender', intergenerational communication between researchers and the role of events such as the Summer Institute in creating an international community of LGBT psychologists. © 2010 Taylor & Francis.

The sound of silence. Lesbian, gay, bisexual and transgender discrimination in 'inclusive organizations'

Most studies on diversity and discrimination in the workplace have focused on 'visible' minorities such as gender or race, often neglecting the experiences of invisible minorities such as lesbian, gay, bisexual and transgender (LGBT) workers. In this paper we explore the practices of inclusion/exclusion of LGBTs in the workplace in Italian social cooperatives, which are specifically founded to create employment for people who are disadvantaged in the labour market. The study examines how organizations, which have an ethos focused on inclusion and mainly employ workers from specific social minority groups, manage the inclusion of LGBT workers. We also explore the experience of LGBT workers within these organizations. The paper reports that the culture of silence existing in the five organizations studied prevents LGBT employees from constructing a work identity which encompasses their sexual identity and prevents the organizations from achieving their aim of being fully inclusive workplaces. © 2013 British Academy of Management.

'Their tummys don't really suit that food':children and young teenagers understanding of food allergy

Background: Food allergy (FA) is aunique chronic condition as sufferers aregenerally well unless they accidentally ingest an allergen, whereupon symptoms can be life threatening. A good under-standing of the condition is essential forsuccessful self-management, however little is known about children and young teenagers' understanding. This study aimed toexplore understanding of FA in childrenwith and without FA and whether under-standing changes as children get older.Method: Participants aged 6–14 years (53with FA; 89 without), recruited from loc evidence of a prospective associationbetween maternal, perinatal or infant VDIand subsequent IgE-mediated FA schools and allergy clinics took part insemi-structured interviews; data were analysed using thematic analysis.Results: Three themes were identified fromthe data across the different age groups andallergy statuses: food allergy as a sickness, food allergy as an illness and food allergy asintolerance to food. Children aged 6–8 years described FA as a sickness; you were not allowed the food because it makes youpoorly. Children aged 9–11 years also talked about FA as something that makesyou poorly, but many also described it as anillness and understood that symptoms were caused by food. Children aged 12–14 yearsdescribed it as an intolerance or that FA was your body's response to a particularfood. These age-related differences wereseen in children with and without FA. Conclusion: Although sophistication ofknowledge of FA increases with age, it is still a little understood condition by chil-dren and young teenagers. Clear, age-re-lated information about food allergy andhow it should be managed is needed forthose with and without allergy, to avoidmisunderstanding, and aid awareness andbetter self-management of the condition

Tooth wear in Irish teenagers: a laboratory and epidemiological study

Aim: To investigate the characteristics, development and determinants of toothwear among Irish schoolchildren. Methods: A cross-sectional (examination at 16-years-old) and longitudinal (examinations at 5-,12-,14-years) study were conducted. Two indices were used to measure toothwear, children/parents completed a demographic profile and questionnaire on oral hygiene and dietary practices, health, and lifestyle in both studies. Saliva was collected from consenting 16-year-olds. The explanatory variables for the cross-sectional and longitudinal study were derived from children/parents responses. Differences in salivary profiles were determined for subsets; the protein concentration was determined with Bradford protein assay and protein carbonyl concentration (a protein oxidation marker) was determined spectrophotometrically. Gel-electrophoresis and mass spectrometry determined proteins and ion chromatography inorganic ions. Statistical significance was accepted at p<0.05. Results: At 16-years-old the prevalence of toothwear with dentine visible was 44%. No difference in salivary flow rates existed. In unstimulated saliva a higher mean, protein carbonyl (p<0.0001) and total calcium concentration (p<0.002) existed for the group with moderate toothwear. In stimulated saliva the moderate toothwear group had a lower mean protein concentration(p<0.0001). The 2-DE protein spots prepared for a sub-group differed between those with toothwear and without. Mass spectrometry, identified one of the different proteins as IgA. For 16-year-olds, the self-reported factors indicated that brushing after breakfast was associated with lower toothwear scores(p<0.03). Nail-biting, being asthmatic or reporting a dry mouth were associated with higher toothwear scores(all p<0.05). Eating an apple daily or less was associated with less toothwear(p<0.002). In the longitudinal study toothwear into dentine at age five or 12-years was associated with more toothwear at age 14(all p<0.05). Discussion: The results illustrate the multifactorial aetiology of toothwear. The biochemical and physical correlates of saliva with toothwear requires further research. Conclusion: The impact of previous toothwear, salivary, dietary and personal factors on toothwear in the early permanent dentition is demonstrated.
