Youth transitioning into university face numerous life challenges, particularly in South Africa with its high levels of poverty and inequality. This article, recognising the vulnerability of many students, sets out to identify the resilience processes that facilitate the resilient outcomes of life satisfaction and academic progress. Using a sample of 232 psychosocially vulnerable undergraduate students, a quantitative survey was conducted and analysed using multivariate procedures. Results indicate that 27% of the variance in life satisfaction was accounted for by 19 resilience variables, with community relationships and family financial security being individually significant, and that 18% of the variance in academic progress was accounted for, with learning orientation being individually significant. Family relationships also emerged as important for both outcomes. The findings suggest that, during times of adversity, South African students draw in particular on relational resources in their home communities, and that academic progress is protected from deterioration by vulnerable students’ love for learning. Practice implications for universities are proposed that go beyond reactive, therapeutic services towards creating a supportive academic community.  相似文献

The crawling behavior of sixty 2-day-old newborns was studied while they were supported prone on a mini skateboard and on a pediatric mattress without additional support. Analyses of the number and types of limb movements and their characteristics, the coactivation of limb pairs, and the displacement across the surface, revealed that newborns can crawl with locomotor patterns similar to those documented during quadrupedal locomotion in animals and human adults. This was particularly apparent on the skateboard. This discovery suggests that locomotor circuitry underlying quadrupedal locomotion develops during fetal life. Drawing upon other evidence for a quadrupedal organization underlying bipedal gait, we argue that early quadrupedal training may enhance interventions designed to hasten the onset of independent walking.  相似文献

When studying verbal materials, both adults and children are often poor at accurately monitoring their level of learning and regulating their subsequent restudy of materials, which leads to suboptimal test performance. The present experiment investigated how monitoring accuracy and regulation of study could be improved when learning idiomatic phrases. Elementary school children (fourth and sixth-graders) were instructed to predict their test performance by providing judgments of learning (JOLs). They provided JOLs immediately after studying each idiom, after studying all idioms, or after studying all idioms followed by generating sentences in which the idioms were used. Correlations between JOLs and test performance showed that delayed-JOLs and delayed-JOLs with sentence generation were more accurate than immediate JOLs. JOLs after sentence generation also improved regulation of study compared to delayed-JOLs only. Analyses of JOL reaction times suggest that delayed-JOLs led children to retrieve the literal meaning of the idiom, whereas JOLs after sentence generation led children to focus on connections between studied information, contextual information, and prior knowledge. Sentence generation presents a promising method to improve regulation of study, and thus idiom learning.  相似文献

Movement patterns during landing have been suggested to be related to injury risk. The purpose of this study was to determine the inter-session reliability of kinematic variables and ground reaction forces during landing in a population of male recreational athletes after a counter movement jump. Both unipodal and bipodal landings were evaluated. Furthermore, the possibility to improve landing reliability with a verbal instruction was also studied. Twenty-four male volunteers with no history of lower extremity trauma were randomly assigned to two groups (with and without verbal landing instruction). An optoelectronic 3D system and force plates were used to measure the lower limb joint angles and the ground reaction forces during landing. Intraclass correlation values show moderate to excellent inter-session reliability for the bipodal task (ICC average: 0.80, range: 0.46–0.97) and poor to excellent reliability for the unipodal task (ICC average: >0.75, range: 0.20–0.95). However, large standard errors of measurement values at the ankle joint at impact (27.6?±?11.5°) and for the vertical ground reaction forces (394?±?1091 N) show that some variables may not be usable in practice. The verbal instruction had a negative effect on the reliability of unipodal landing but improved the reliability of bipodal landing. These findings show that the reliability of a landing task is influenced by its motor complexity as well as the instruction given to the subject.  相似文献

Two experimental studies examined the effects of different types of phonemic segmentation training on phonemic segmentation, reading and spelling. Children with learning disabilities, who were weak in phonemic segmentation, were trained with the use of diagrams and alphabet letters, with alphabet letters only, or with no visual support at all (the control condition). For this purpose three computer-assisted training programs were developed. In the first experiment, 48 children were assigned to one of the three programs. The training period lasted five weeks. Although in each training program the children improved their phonemic segmentation skill, there were no significant differences among the three training programs. This result may have been influenced by the different types of feedback that were provided in the three training programs. In a second experiment, therefore, these differences in feedback were eliminated and 49 different children were trained with the same three programs. The results of this experiment, however, were the same as those of the first experiment. The finding that visual support had no beneficial effects could therefore not be attributed to differences in explicit feedback. It was concluded that with these children, in contrast to preschoolers, phonemic segmentation training using visual support does not have any advantage over auditory training alone. The results of this study indicate that preschoolers and children with reading and spelling problems cannot be treated in the same way. It underlines the importance of further examination of the problems that poor readers and poor spellers encounter in grasping the structure of spoken language.  相似文献

Abstract

Sport science is a relatively recent domain of research born from the interactions of different disciplines related to sport. According to the European College of sport science (http://sport-science.org): “scientific excellence in sport science is based on disciplinary competence embedded in the understanding that its essence lies in its multi- and interdisciplinary character”. In this respect, the scientific domain of neuroscience has been developed within such a framework. Influenced by the apparent homogeneity of this scientific domain, the present paper reviews three important research topics in sport from a neuroscientific perspective. These topics concern the relationship between mind and motor action, the effects of cognition on motor performance, and the study of certain mental states (such as the “flow” effect, see below) and motor control issues to understand, for example, the neural substrates of the vertical squat jump. Based on the few extensive examples shown in this review, we argue that by adopting an interdisciplinary paradigm, sport science can emulate neuroscience in becoming a mono-discipline.  相似文献

Adolescence is marked by the development of personal identity and is associated with structural and functional changes in brain regions associated with Self processing. Yet, little is known about the neural correlates of self‐reference processing and self‐reference effect in adolescents. This functional magnetic resonance imaging study consists of a self‐reference paradigm followed by a recognition test proposed to 30 healthy adolescents aged 13–18 years old. Results showed that the rostral anterior cingulate cortex is specifically involved in self‐reference processing and that this specialization develops gradually from 13 to 18 years old. The self‐reference effect is associated with increased brain activation changes during encoding, suggesting that the beneficial effect of Self on memory may occur at encoding of self‐referential information, rather than at retrieval.  相似文献

This article explores the opportunities to apply cognitive load theory and four-component instructional design to self-directed learning. Learning tasks are defined as containing three elements: learners must (a) perform the tasks, (b) assess their task performance, and (c) select future tasks for improving their performance. Principles to manage intrinsic and extraneous load for performing learning tasks, such as simple-to-complex ordering and fading-guidance strategies, are also applicable to assessing performance and selecting tasks. Moreover, principles to increase germane load, such as high variability and self-explanation prompts, are also applicable to assessment and selection. It is concluded that cognitive load theory and four-component instructional design provide a solid basis for a research program on self-directed learning.  相似文献

Agreement between 57 African American mothers and their early adolescent daughters on measures of maternal support, maternal restrictive control, and parent-adolescent conflict were examined. To assess the relative validity of these reports, the study then evaluated them against the ratings of independent observers. Additionally, mother and daughter reports were combined to examine validity coefficients based on aggregate scores of each construct. All analyses were based on 2 sets of objective criterion ratings, ratings provided by coders of similar ethnic background (African American) and coders who were ethnically dissimilar (non-African American) to the families they rated. Overall, adolescents provided ratings that were more valid than those of their mothers when evaluated against both sets of independent ratings. Adolescent ratings of maternal control and parent-adolescent conflict converged at significantly higher levels than the ratings provided by their mothers. Maternal and adolescent reports of maternal support converged with objective criteria at statistically comparable levels. Validity coefficients for adolescent reports were also higher than those based on aggregate mother-daughter scores. Secondary analyses further revealed that African American coders rated mothers as less controlling and rated the dyadic interactions as less conflictual, and that their ratings were more consistent with the perceptions of the African American mothers and adolescents than were those provided by non-African American coders.  相似文献

A small group of children and young adolescent with dyslexia has severely impaired reading skills despite prolonged special education. These are the students in focus. In dyslexia, problem behaviour, internalised as well as externalised, has previously been reported, so also for the participants with dyslexia in this study. The aim of the present study was to obtain more in‐depth knowledge of the behaviour problems from various informants, representing different settings. This kind of information is imperative for identifying problem behaviour, and for planning and implementing remedial programmes. A clinical group of 70 students with severe dyslexia, due to phonological problems, and a control group of 70 without reading problems participated. The two groups were pair‐wise matched on age, gender, cognitive level and whether they lived in rural or urban areas. Mean age was 150 months, and mean IQ was approximately 100 in both groups. Parents, teachers and participants provided information on behaviour through the Achenbach questionnaires Child Behavior Checklist, Teacher's Report Form and Youth Self Report. Behaviour is, in these questionnaires, divided into eight syndrome areas called Withdrawn, Somatic Complaints, Anxious/Depressed, Social Problems, Thought Problems, Attention Problems, Delinquent Behavior and Aggressive Behavior. The three informant groups reported significantly more problems in the dyslexia group than in the controls in all the syndrome areas. Parents reported more children with dyslexia to be anxious and depressed, and have social problems and attention problems than teachers. They also reported suicidal ideations in nine participants with dyslexia. In addition, parents rated more internalising and total problems in the dyslexia group than teachers.  相似文献
