Abstract As the number of children diagnosed with, and medicated for, Attention‐Deficit/Hyperactivity Disorder (ADHD) increases at an alarming rate there have been questions raised as to whether ADHD is really a disorder or merely a fabricated and socially constructed problems However, there is much evidence which shows that ADHD related difficulties have been observed in children for at least the past century. This paper will provide a detailed account of this evidence and will show that ADHD is a disorder which has affected our children form at least the past 100 years 相似文献

The time course of learners’ processing of a complex animation was studied using a dynamic diagram of a piano mechanism. Over successive repetitions of the material, two forms of cueing (standard colour cueing and anti-cueing) were administered either before or during the animated segment of the presentation. An uncued group and two other control conditions were also employed. Development of an internal representation of the movements depicted in the animation was evaluated through participant demonstrations of the mechanism’s operation on a replica piano mechanism. Eye tracking (fixation lengths) indicated that overall, conventional visuospatially-based cueing was largely ineffective for directing attention across the presentations of the animation. Demonstration scores from cued animations were no better than those produced from the uncued version. Cue obedience for standard colour cueing was initially superior to that for anti-cues but fell away after the animation’s first exposure. Contrary to expectations, there was no difference in cue obedience for cueing applied before or during animation of the display. The findings suggest that alternatives to visuospatial cues are needed to help learners process complex animations more effectively. 相似文献

A key requirement of successful initial teacher education is the development of professional vision, which includes shifting attention to features of the situation relevant to the specialized goals of teaching. Existing research hints at the value of targeted video-based courses in the development of professional vision, but often raises questions about the sources of shifts in the pattern of attention. We argue that existing work makes it difficult to distinguish whether shifts seen across video interventions are the results of the intervention, teaching experience, or methodological issues with the unbalanced use of videos in the data collection in these studies. Our first study suggests pre-service teachers’ teaching practice experience does not notably affect attention, but that choice of video does. Our second study addresses the methodological issues and suggests that we may discount different or unbalanced videos as a source of the shifts in the pattern of attention. Finally, by introducing a new synthesis of the results in the literature, we identify a previously hidden key distinction between studies and suggest reasons why different studies have shown different results in this area. 相似文献

The advantage in learning after an intradimensional shift rather than an extradimensional shift has been widely used as a behavioural marker of attentional changes during discrimination learning in different fields of neuroscientific study. However, some of the factors assumed to guide these attentional changes have not been completely disentangled by previous research. In two predictive-learning experiments, we investigated the importance of stimulus relevance and of stimulus-outcome correlation for the modulation of attention. In each experiment, participants were trained on two discrimination problems given in successive order. Each problem required participants to differentiate stimuli varying on two dimensions. We found that acquisition of the second discrimination was influenced by whether its relevant dimension (Exp. 1) or its irrelevant dimension (Exp. 2) had previously been trained as relevant and uncorrelated or as irrelevant and uncorrelated. We also observed that acquisition of the second discrimination was independent of whether its relevant dimension (Exp. 1) or its irrelevant dimension (Exp. 2) had previously been trained as relevant and uncorrelated or as relevant and correlated. Our results indicated that the modulation of attention is guided by stimulus relevance and not by stimulus-outcome correlation. 相似文献

It is well known that many pupils are bullied and suffer in a variety of ways as a result. This study looks at a largely overlooked outcome of bullying that may have direct consequences for academic success – disrupted concentration and attention to school work. Using pupil perceptions as the source of data, the two main aims were to quantify the proportion of pupils affected by bullying in this way, and to solicit their views on possible solutions. Subsidiary aims were to test for gender and school year differences in these variables. Among the 485 participants as a whole, only modest levels of disruptions attributable to bullying were evident but more disturbing was the finding that on nine out of eleven separate questions, around one in twenty pupils reported that this happened ‘lots of times’. The most common solutions provided by pupils to help children affected in this way involved:
-
helping them feel safe from bullying in class;
-
reminding them to disclose/seek help if they are bullied;
-
encouraging teachers to be supportive of victims of bullying;
-
encouraging teachers to be on the look out for signs that pupils have been bullied; and
-
using social support from other pupils.

This study investigates early childhood prospective teachers’ attention to geometrical tasks while designing and using them in the classroom. This is explored in the context of the teaching practice of 11 prospective teachers who taught geometry in early childhood classrooms during the last semester of their university studies. The teaching practice was organized into four stages: design of a lesson plan; classroom implementation; discussion of the lesson with the school practice instructor; and self-assessment report and revision of the lesson. Analysis of data using the Teaching Triad framework (Jaworski, 1994) shows that although the prospective teachers attended to issues of mathematical challenge, sensitivity to students, and management of learning in their planning, in their actual teaching and after class reflection, their attention was focused mainly on management issues. The findings also show that prospective teachers’ attention on geometrical tasks can be developed through a process of reflection on their teaching. 相似文献

The aim of the present study was to clarify the nature of the ability-specific and position-specific components of Raven's Advanced Progressive Matrices (APM) by relating them to a number of types of attention. The ability-specific component represents the constant part of cognitive performance whereas the position-specific component reflects the changes in processing of reasoning items as a result of the changing item position. A special model denoted fixed-links model was used to decompose the data of APM into independent components. Both components were related to two higher-order units of attention, perceptual attention and executive attention, which were derived from the various types of attention. In a sample of 226 participants the position-specific component of APM showed a substantially higher link with executive attention than with perceptual attention whereas the ability-specific component only showed a moderate link with perceptual attention. 相似文献

There are few studies that have directly examined teachers’ perceptions of children with ADHD, particularly children in the adolescent age range. The purpose of this study was to examine the perceptions of general‐education ninth through twelfth grade teachers regarding working with adolescent students with ADHD. Sorted responses from a sample of 100 general‐education high school teachers were analysed and then represented visually using a concept‐mapping technique. The final concept map suggests that teachers perceive adolescents with ADHD along two dichotomies of thematic clusters on an orthogonal axis. Clusters at the top area of the concept map suggest perceptions related to high confidence and willingness, while clusters at the bottom suggest perceptions related to uneasiness and frustration. Clusters along the left side of the concept map suggest perceptions related to behaviour issues, while clusters along the right side suggest perceptions related to classroom teaching issues. Central to the vertical and horizontal dichotomies is a solitary central dimension, which highlights training as an important component of teachers’ perceptions of adolescents with ADHD. 相似文献

The term “intellectually gifted rural-to-urban migrant children” refers to intellectually gifted children who are in migration from rural to urban areas. We compared performances on seven attention tasks among intellectually gifted (n = 26) and average (n = 30) rural-to-urban migrant and intellectually gifted urban children (n = 31). Our results showed that intellectually gifted rural-to-urban migrant children performed more correctly and faster on some attention tasks than did the intellectually average rural-to-urban migrant children, but they did not perform as well on some attention tasks as did the intellectually gifted urban children. Based on the attentional structures, it was evident the intellectually gifted rural-to-urban migrant children developed more mature than did either the intellectually gifted urban or the intellectually average rural-to-urban migrant children. This suggests the intellectually gifted rural-to-urban migrant children’s attention is overall superior to that of their intellectually average peers. However, there are advantages and disadvantages in terms of the quality of their attention compared to the intellectually gifted urban children. While their attentional structures seem to develop earlier, their accuracy on some of the attention tasks seems to suffer. This suggests that rural-to-urban migration is a double-edged sword for intellectually gifted children. 相似文献

Potential effects of auditory and other communicative experience on development of visual attention were investigated for four groups of infants at 9, 12, and 18 months of age. Participants included 20 deaf infants with deaf mothers, 19 deaf infants with hearing mothers, 21 hearing infants with hearing mothers, and 20 hearing infants with deaf mothers. Infants' hearing status alone did not associate with patterns of visual attention. Deaf infants with deaf mothers showed significantly longer times in the most advanced attention state (coordinated joint) than did deaf infants with hearing mothers. However, other aspects of experience were associated with group differences. Both deaf and hearing children with deaf mothers who signed spent more time onlooking (or watching) their mothers than did children (deaf or hearing) with hearing mothers. Hearing children with hearing mothers spent more time looking at objects than did children with deaf mothers. Despite these differences in time in various attention states, the general trajectory of development of each of the attention states was similar across groups. Results indicate that early visual attention is associated with and potentially influenced by a complex interaction of maturation, communicative experiences, and other developing skills. 相似文献

Orthographic facilitation refers to the boost in vocabulary learning that is provided when spellings are shown during study periods, but not during testing. The current study examined orthographic facilitation in beginning readers and whether directing their attention to print enhances the effect. In an experiment, first graders (N = 45) were randomly assigned to either an attention or no attention condition. They studied two sets of novel spoken words paired with pictures and spoken definitions, one set displaying spellings of the words beneath pictures, and one set with no spellings. Tests with no spellings present revealed that children learned pronunciations of words significantly better when spellings had been seen than not seen, and the benefit was still evident 2 weeks after training ended. Superior ability to spell the words by children who saw them showed that spellings were retained in memory to support learning. More advanced readers gained more benefit from spellings over no spellings in learning the words. However, drawing children’s attention to print did not boost memory for the words, suggesting that simple exposure was sufficient to activate grapheme-phoneme connections automatically and bond spellings to pronunciations of words in memory, even in beginning readers. Memory for the meanings of words was not improved by spelling exposure, possibly because children possessed no grapho-semantic mapping system comparable to the grapho-phonemic system to enhance the formation of connections between spellings and meanings in memory. 相似文献

A controversy has recently developed regarding the hypothesis that developmental dyslexia may be caused, in some cases, by a reduced visual attention span (VAS). To examine this hypothesis, independent of phonological abilities, researchers tested the ability of dyslexic participants to recognize arrays of unfamiliar visual characters. Employing this test, findings were rather equivocal: dyslexic participants exhibited poor performance in some studies but normal performance in others. The present study explored four methodological differences revealed between the two sets of studies that might underlie their conflicting results. Specifically, in two experiments we examined whether a VAS deficit is (a) specific to recognition of multi-character arrays as wholes rather than of individual characters within arrays, (b) specific to characters’ position within arrays rather than to characters’ identity, or revealed only under a higher attention load due to (c) low-discriminable characters, and/or (d) characters’ short exposure. Furthermore, in this study we examined whether pure dyslexic participants who do not have attention disorder exhibit a reduced VAS. Although comorbidity of dyslexia and attention disorder is common and the ability to sustain attention for a long time plays a major rule in the visual recognition task, the presence of attention disorder was neither evaluated nor ruled out in previous studies. Findings did not reveal any differences between the performance of dyslexic and control participants on eight versions of the visual recognition task. These findings suggest that pure dyslexic individuals do not present a reduced visual attention span. 相似文献

Nigel Mellor recently retired from his work with the educational psychology service in North Tyneside. In this article, he proposes that attention-seeking behaviour may lead to major difficulties at home and school and indicates the ways in which recent research is beginning to clarify the area. Attention deficit disorders also cause great concern. However, the extremely widespread range of attention-seeking behaviours may easily lead to their being confused with attention deficit/hyperactivity disorder (AD/HD). Nigel Mellor explores ways to distinguish these two behaviour problems. This, he argues, may help target interventions more efficiently. However, a great deal of further research is called for. 相似文献

Social contexts shape the development of attention; however, little is known about joint attention beyond infancy. This study employed behavioral and eye-tracking measurements to investigate cultural variations in how caregivers direct 3- to 4-year-old children's attention and subsequent changes in children's attention to objects and contextual backgrounds in the United States (predominantly non-Hispanic Whites) and Japan (N = 60 mother-child dyads, 29 girls, 31 boys). The findings revealed that caregivers directed children's attention to culturally sensitive information, and significant cross-cultural differences in attention emerged after caregiver–child interaction, with Japanese children shifting their attention to the backgrounds. Results provide new insights into the role of social interaction and cultural diversity in the development of attention. 相似文献

Professional vision research lacks behind regarding the investigation of attention processes in teaching action. In this study, eye movements of preservice teachers were assessed by mobile eye-tracking technology (MET). Eye movements of N = 7 preservice teachers while teaching in standardized instructional situations (M-Teach) and while teaching in classroom were recorded and analyzed with regard to fixation frequency and fixation duration. According to assumptions of expertise research, the results show that preservice teachers strongly differ in their focus of attention. Furthermore, they show that preservice teachers distribute their attention only over a few pupils while teaching. The findings provide important implications with regard to the question how to support attentional processes even at an early stage of professional development, for example by observing own MET videos. 相似文献
