In 5 experiments, 4-month-old infants were tested for their ability to recognize degraded visual targets as a function of individual differences in fixation duration. Targets were degraded by removing 10% of the total contour either from vertices (vertex-absent) or from midsegments (vertex-present). Both qualitative and quantitative differences were found in long and short lookers' ability to recognize the degraded forms. Short-looking infants were able to recognize degraded forms in both vertex-absent and vertex-present conditions, but the vertex-absent discrimination was more difficult. Long-looking infants required longer familiarization times before showing evidence of recognition in the vertex-present condition, and were unable to recognize targets in which contour was removed at vertices. The findings are discussed within the framework of the persistence of early visual processing strategies, and reliance of long-looking infants on particular local elements in visual analysis. 相似文献

The Attitudes to Deafness Scale is a 22-item measure of attitudes toward people who are deaf designed for use with human service professionals. Attitude statements were generated from personal accounts by deaf people in the literature and from a focus group in which deaf people discussed their experience of hearing people's attitudes toward them. A 60-item scale was administered to a group of 121 clinical and forensic psychologists during their training. Item analysis was conducted to select items that effectively distinguished participants with a positive attitude from those with a negative attitude toward deaf people. The scale may be used in any context where a professional group comes into contact with people who are deaf. 相似文献

A developmental-genetic analysis of common fears from early adolescence to early adulthood 总被引:1,自引:0,他引:1
A 51-item fear survey was administered to more than 2,600 adolescents and adults, including m ore than 400 pairs of like-sex twins, to examine developmental patterns and genetic influences on common fears. Raw data were age-sex standardized and subjected to factor analysis, and preliminary analyses of the factor scores documented both age and genetic effects. Some fears habituate with age; others exhibit sensitization; and, for some fears, intensity is uniform across development. Genetic effects were found for all factors, but the magnitude of such effects varied. Based on these initial analyses, developmental patterns of genetic and environmental influences on self-assessed fears were examined in 354 pairs of like-sex twins, ages 14-34. Hierarchical multiple regression was used to predict a twin's fearfulness from the co-twin's fear, the age and zygosity of the twin pair, and the interactions of these 3 predictors. For all fear factors, co-twin's score and the interaction of co-twin's score with pair zygosity significantly contributed to the prediction of a twin's fearfulness, but the magnitude of both effects varied for different fears. For 2 fear factors, Personal Death and Loved One's Misfortunes, 3-way interactions of co-twin's score, age, and zygosity were observed. The findings suggest significant genetic modulation of developmental patterns in the acquisition and maintenance of some adaptive fears. 相似文献

Many undergraduate students in kinesiology are interested in clinical careers and seek research opportunities for advanced study and unique learning experiences. This article describes a process of engaging undergraduate students in a multi-disciplinary, National Institutes of Health (NIH)-funded program project investigating factors that may affect pelvic floor support and symptoms in primiparous women during the first year postpartum. Students complete general and protocol-specific training prior to engagement, have specific tasks that reinforce skill development and require independence, and are invited to participate in additional opportunities with the investigative team. The topic of pelvic floor health is novel to most students and participation in this research expands their knowledge beyond a mainstream kinesiology curriculum. Institutionalizing this type of program could formalize undergraduate student research experiences and facilitate ongoing clinical research efforts with a kinesiology focus. 相似文献

Nationwide survey of postsecondary education services for students with learning disabilities 总被引:1,自引:0,他引:1
Postsecondary services for students with learning disabilities vary a great deal from campus to campus, and published guides to postsecondary education services are often inaccurate and incomplete. A nationwide survey was conducted to investigate student service provisions in 2-year colleges and 4-year colleges and universities. The purpose of the study was to identify and catalog postsecondary education service goals and options for students with learning disabilities, and to determine differences between the goals service providers have for these students and services actually provided. The findings and their implications for service providers at both high school and college levels are discussed. 相似文献

In two studies, undergraduates learned a map of the city of Rome in either a flat survey map or a one-point perspective format. The perspective map lead to greater feature recall in the first study and to better memory for a related text when features were correctly located in the second study. Both studies suggest that map scanning patterns may differ depending on the learner′s point of view. 相似文献

7-month-old full-terms and high-risk preterms (less than 1,500 grams at birth) were compared on problems of visual recognition memory and tactual-to-visual cross-modal transfer. On the visual problems, preterm infants showed significantly less differential attentiveness to novelty than full-terms. They also required longer exposure times during visual familiarization, primarily because of longer pauses between fixations. Preterms and full-terms exhibited different patterns of looking, as indicated by the duration of fixation and the frequency in shifts of gaze. On the cross-modal problems, preterms and full-terms both exhibited similar and significant preferences for familiar rather than novel stimuli, a direction of preference which suggests that these problems were relatively difficult for both groups. For the preterms, novelty and exposure-time scores were found to be related to several medical risk factors. Novelty preferences were compromised in preterms who had suffered RDS postnatally, particularly those who had required prolonged mechanical ventilation. In general, high-risk preterms exhibited deficits in visual recognition memory and in the ability to recruit, sustain, and shift attention. 相似文献

Networked environments offer new scope for presenting activity based courses, in which activities and reflection form the central backbone of course pedagogy. Such courses promise an enriching approach to study, but there are also challenges for the design of assessment. This paper describes a qualitative study of student and tutor perspectives on the assessment of an innovative undergraduate course at the UK Open University which has employed an activity–based approach. It discusses the relationship between assessment, student participation, and the development of skills, and then outlines the priorities for the design of assessment for such courses. 相似文献
