There is an ongoing debate whether phonological deficits in dyslexics should be attributed to (a) less specified representations of speech sounds, like suggested by studies in young children with a familial risk for dyslexia, or (b) to an impaired access to these phonemic representations, as suggested by studies in adults with dyslexia. These conflicting findings are rooted in between study differences in sample characteristics and/or testing techniques. The current study uses the same multivariate functional MRI (fMRI) approach as previously used in adults with dyslexia to investigate phonemic representations in 30 beginning readers with a familial risk and 24 beginning readers without a familial risk of dyslexia, of whom 20 were later retrospectively classified as dyslexic. Based on fMRI response patterns evoked by listening to different utterances of /bA/ and /dA/ sounds, multivoxel analyses indicate that the underlying activation patterns of the two phonemes were distinct in children with a low family risk but not in children with high family risk. However, no group differences were observed between children that were later classified as typical versus dyslexic readers, regardless of their family risk status, indicating that poor phonemic representations constitute a risk for dyslexia but are not sufficient to result in reading problems. We hypothesize that poor phonemic representations are trait (family risk) and not state (dyslexia) dependent, and that representational deficits only lead to reading difficulties when they are present in conjunction with other neuroanatomical or—functional deficits. 相似文献

White British Muslims pose a challenge to racialised representations of British Muslims as non‐white, foreign and Other. By drawing on tools from Critical Discourse Analysis to develop Social Representations Theory on a micro‐analytic level, and making connections with other relevant social psychological theories on intergroup relations, this article examines the constructions of white British Muslims as a threat in six national and two Muslim British newspapers. It looks at how discourses are used to create, perpetuate and challenge the ‘hegemonisation’ of social representations in majority and minority press. The findings show that white British Muslims are portrayed as a threat not just despite of, but because of, their position as part of the ‘white British’ ingroup. Consequently, the threat they pose often leads to their Muslimness being emphasised. This was, at times, contested, however, either through direct challenges, or by making the threat ambivalent by drawing on their whiteness. 相似文献

Abstract After completion of an illness symptom checklist (PILL) covering the previous three months, 97 nor-motensives were allocated to either experimental (false pressor feedback, n=42), or information control (accurate pressor feedback, n = 55), groups. The median reported symptom score divided high from low symptom subjects. All were given standard cuff blood pressure (BP) assessment and were normotensive. However, experimental subjects were misinformed that their BP was raised while information control subjects were told their BP was normal. Subsequently, subjects completed the state anxiety form of the State-Trait Personality Inventory, the PILL, and were asked about their belief of the ascribed BP label (normo/hypertensive) and then any perceived causal relationship between their BP and symptoms. Experimental subjects had significantly higher anxiety scores but no change in symptom recall after pressor feedback, whereas control subjects showed lower anxiety scores and decreases in symptom recall. A post hoc treatment control (no pressor information) group (n = 20) excluded effects of BP labeling on post-BP scores, and a post hoc symptom control group (n = 55) ensured that symptom levels were representative of the normal population. The majority of subjects in both groups rejected any association between BP labels and symptoms. Data are discussed in the light of Leventhal's models of illness representation. 相似文献

The present study reports an application of the common sense model (CSM) of illness representations to the prediction of psychological distress in people with Parkinson's disease (PD). The study sought to (i) examine cross-sectional and prospective associations between illness representations, coping and psychological distress, and (ii) test the hypothesis that coping would mediate any relationships between illness representations and psychological distress. Patients with PD (n = 58) completed the Illness Perception Questionnaire-Revised, the Medical Coping Modes Questionnaire and the Hospital Anxiety and Depression Scale. Patients (n = 57) were followed-up at 6 months. Illness representations explained large amounts of variance in time 1 anxiety (R 2 = 0.42) and depression (R 2 = 0.44) as well as additional variance in time 2 anxiety (ΔR 2 = 0.12) and depression (ΔR 2 = 0.09) after controlling for baseline scores. In addition, avoidance mediated the effect of emotional representations on time 1 anxiety, and acceptance-resignation mediated the effects of both consequences and emotional representations on time 1 depression. The present study therefore provides partial support for the mediational model outlined in the CSM, as significant mediation effects were found only in the cross-sectional analyses. 相似文献

The promotion of breastfeeding is an important focus of intervention for professionals working to improve infant health outcomes. Literature in this area focuses largely on ‘choices’ and ‘barriers to breastfeeding’. It is our argument, however, that women's cultural context plays a key role in infant feeding ‘choices’. In this article, we explore contested representations of infant feeding and infant feeding choices in public debates conducted on a large British parenting website. To sample dominant representations of infant feeding circulating in UK culture, two threads were chosen from the debating board of a busy online parenting community (105 and 99 individual posts, respectively). Participants on the threads were largely women. A feminist informed Foucauldian discourse analysis was used to deconstruct the intersecting constructions of gender, childhood and motherhood implicit in public discussions about infant feeding choices. We identify dominant constructions of women who breastfeed or bottle feed, social representations of both forms of infant feeding, and explore the relationship between constructions of infant feeding choices and constructions of ‘good’ or ‘bad’ motherhood. This analysis functions to trouble the individualist assumptions underpinning the notion of infant feeding ‘choices’, considering the cultural context within which British mothers ‘choose’ how to feed their babies. 相似文献

When people hold several objects (such as digits or words) in working memory and select one for processing, switching to a new object takes longer than selecting the same object as that on the preceding processing step. Similarly, selecting a new task incurs task- switching costs. This work investigates the selection of objects and of tasks in working memory using a combination of object-switching and task-switching paradigms. Participants used spatial cues to select one digit held in working memory and colour cues to select one task (addition or subtraction) to apply to it. Across four experiments the mapping between objects and their cues and the mapping between tasks and their cues were varied orthogonally. When mappings varied from trial to trial for both objects and tasks, switch costs for objects and tasks were additive, as predicted by sequential selection or resource sharing. When at least one mapping was constant across trials, allowing learning of long-term associations, switch costs were underadditive, as predicted by partially parallel selection. The number of objects in working memory affected object-switch costs but not task-switch costs, counter to the notion of a general resource of executive attention. 相似文献

Though figure–ground assignment has been shown to be probably affected by recognizability, it appears sensible that object recognition must follow at least the earlier process of figure–ground segregation. To examine whether or not rudimentary object recognition could, counterintuitively, start even before the completion of the stage of parsing in which figure–ground segregation is done, participants were asked to respond, in a go/no-go fashion, whenever any out of 16 alternative connected patterns (that constituted familiar stimuli in the upright orientation) appeared. The white figure of the to-be-attended stimulus—target or foil—could be segregated from the white ambient ground only by means of a frame surrounding it. Such a frame was absent until the onset of target display. Then, to manipulate organizational quality, the greyness of the frame was either gradually increased from zero (in Experiment 1) or changed abruptly to a stationary level whose greyness was varied between trials (in Experiments 2 and 3). Stimulus recognizability was manipulated by orientation angle. In all three experiments the effect of recognizability was found to be considerably larger when organizational quality was minimal due to an extremely faint frame. This result is argued to be incompatible with any version of a serial thesis suggesting that processing aimed at object recognition starts only with a good enough level of organizational quality. The experiments rather provide some support to the claim, termed here “early interaction hypothesis”, positing interaction between early recognition processing and preassignment parsing processes. 相似文献
