Dyslexia in adults: Evidence for deficits in non-word reading and in the phonological representation of lexical items     

Carsten Elbro  Ina Nielsen  Dorthe K. Petersen 《Annals of dyslexia》1994,44(1):203-226

Difficulties in reading and language skills which persist from childhood into adult life are the concerns of this article. The aims were twofold: (1) to find measures of adult reading processes that validate adults’ retrospective reports of difficulties in learning to read during the school years, and (2) to search for indications of basic deficits in phonological processing that may point toward underlying causes of reading difficulties. Adults who reported a history of difficulties in learning to read (n=102) were distinctly disabled in phonological coding in reading, compared to adults without similar histories (n=56). They were less disabled in the comprehension of written passages, and the comprehension disability was explained by the phonological difficulties. A number of indications were found that adults with poor phonological coding skills in reading (i.e., dyslexia) have basic deficits in phonological representations of spoken words, even when semantic word knowledge, phonemic awareness, educational level, and daily reading habits are taken into account. It is suggested that dyslexics possess less distinct phonological representations of spoken words. This research was supported by a grant from the Danish Research Council to the first author.  相似文献   

Can images provide contextual support for prose?     

Robert M. Bernard  Chris H. Petersen  Mohamed Ally 《Educational technology research and development : ETR & D》1981,29(2):101-108

This study sought to determine whether contextual organizers presented before prose passages can improve learning and retention among students who have no prior knowledge of the subject. The researchers used two types of organizers — an image and its verbal equivalent. Students who were provided the organizers scored better than control students on tests given two weeks later, but the predicted advantage of images over verbal learning adjuncts did not appear.  相似文献   

Sexual violence and youth in South Africa: the need for community-based prevention interventions     

Petersen I  Bhana A  McKay M 《Child abuse & neglect》2005,29(11):1233-1248

OBJECTIVES: South Africa is reported to have one of the highest rates of sexual violence in the world, with adolescent girls between the ages of 12-17 being particularly at risk. Given that adolescence is considered a critical developmental period for establishing normative sexual behavior, this study explored multiple levels of risk influences that render adolescent girls vulnerable to becoming victims of sexual violence and adolescent boys vulnerable to becoming perpetrators of such abuse in one South African community. METHOD: A case study approach using qualitative rapid focused ethnographic methods was used. This involved 10 focus group interviews and 10 individual interviews with a volunteer convenience sample of adolescent boys and girls between the ages of 14 and 16 years. RESULTS: Inductive thematic analysis revealed that there were indeed multiple levels of risk influences for adolescent girls and boys becoming either victims or perpetrators of sexual violence. Using the Theory of Triadic Influence as a framework, influences at the distal socio-cultural/environmental level included traditional notions of masculinity and normalization of inter-personal violence as well as poverty and the commodification of sex leading to rape supportive attitudes. Influences at the proximal situation context/social normative level included high-risk social norms as well as a weak adult and community protective shield. Finally, influences at the intra-personal level included low self-esteem and self-efficacy as well as inter-personal affective anger. CONCLUSION: Given the multiple levels of risk influences that need to be addressed to protect youth from becoming either perpetrators or victims of sexual violence in the South African context, prevention programs should necessarily be comprehensive, developmentally timed, and community-based.  相似文献

Acts of Irreconcilable Mourning: Post-Holocaust Witness and Testimony     

Jill Petersen Adams 《Culture, Theory & Critique》2013,54(2):228-244

Abstract

This essay revisits the question of post-Shoah responses to cataclysm in light of the now-urgent question of transmission – the shift in mourning and memory between first-generation survivors and later generations. Offering a different but complementary analysis to those in trauma or memory studies, I argue that post-Shoah witness and testimony are acts of ‘irreconcilable mourning’. This sense of mourning departs from post-Freudian approaches that focus on closure. Instead, irreconcilable mourning is a non-totalising approach to loss that resists ‘redemption’ and instead necessitates an ongoing, creative, and critical response to loss. In the course of this argument, I examine first-generation accounts such as Primo Levi's and Elie Wiesel's to highlight the necessity and contingency of transmission by interrogating concepts such as the ‘unsayable’ and the remnant. I then focus on Art Spiegelman's second-generation Maus: A Survivor's Tale, bringing cross-generational questions of witness and testimony as acts of irreconcilable mourning into the fold of Marianne Hirsch's ‘postmemory’ and Edith Wyschogrod's heterological history-telling.  相似文献   

Imagining the possibilities: qualitative inquiry at the intersections of race,gender, disability,and class     

Amy J. Petersen 《International journal of qualitative studies in education》2013,26(6):801-818

This paper reflects upon the methodology and methods of a qualitative study that examined the lived educational experiences of four African-American women labeled with disabilities and from low socioeconomic backgrounds. This paper offers discussion as to the usefulness of alternate methods of representing data, specifically poetry and narrative, as a means of circumventing dilemmas associated with intersectional research and promoting more equitable research processes for individuals that have been historically marginalized by traditional research methods. How qualitative inquiry may enhance and bring about new insights into the lived experiences of individuals located at marginalized and intersecting discourses is explored.  相似文献   

Stop,Think, Do! Treating and Preventing Social-Behavioural Problems in School     

Lindy Petersen 《Pastoral Care in Education》2013,31(2):17-22

Most teachers will come into contact with pupils who are experiencing or have experienced a loss or bereavement and they often feel ill equipped to offer the kind of support they would like to. This paper offers insights into the nature of this area and a specific approach through which children may be supported. The writer discusses some research and thinking on loss and bereavement and the implications of this. She presents two case studies of work with individual students using the creative arts. She also discusses the connections between behavioural problems, loss and the use of the arts in supporting the students.  相似文献   

Effects of endurance training on transient oxygen uptake responses in cyclists   总被引：1，自引：0，他引：1  

Norris SR  Petersen SR 《Journal of sports sciences》1998,16(8):733-738

The aim of this study was to determine the alterations in oxygen uptake kinetics following endurance training in previously trained athletes. Sixteen competitive cyclists completed 8 weeks of supervised endurance cycle training. Ventilatory threshold, maximal oxygen uptake (VO2max), oxygen uptake kinetics and simulated 40-km time-trial tests were performed three times over a 4-week period before training, and then after 4 and 8 weeks of training. The protocol for measuring oxygen uptake kinetics consisted of three square-wave increments from unloaded cycling to a power output of 78 W followed by a single increment from 78 to 156 W. No significant differences in any variables were observed over the pre-training period. The ventilatory threshold and VO2max increased, and the time for 40 km decreased (P < 0.05) with training. Shorter VO2 time constants and lower heart rates were observed during the protocol for measuring oxygen uptake kinetics (same absolute power output) post-training. These results indicate that oxygen uptake kinetics may be improved with endurance training in previously trained athletes.  相似文献

Sex differences in mental strategies for single-digit addition in the first years of school     

Pernille B. Sunde  Peter Sunde  Judy Sayers 《教育心理学》2020,40(1):82-102

Abstract

Strategy use in single-digit addition is an indicator of young children’s numeracy comprehension. We investigated Danish primary students’ use of strategies in single-digit addition with interview-based assessment of how they solved 36 specific single-digit addition problems, categorised as either ‘error’, ‘counting’, ‘direct retrieval’ or ‘derived facts’. The proportional use of each strategy was analysed as multi-level functions of school age and sex. In a first study (260 interviews, 147 students) we found decreasing use of counting and increasing use of direct retrieval and derived facts through years 1–4, girls using counting substantially more and the other two strategies substantially less than boys, equal to more than 2 years’ development. Similar results appeared in a subsequent study (155 interviews, 83 students), suggesting that the pattern is pervasive in Danish primary schools. Finally, we ask whether sex differences in strategy use is generally under-reported since many studies do not explicitly address them.  相似文献
