This study examined 164 African American adolescents’ (Mage = 15) daily reports of racial discrimination and parental racial socialization over 21 days. The study examined same-day and previous-day associations of adolescents’ discrimination and socialization experiences with their positive and negative psychological affect. It further explored whether racial socialization messages buffered discrimination’s effects on affect when messages were received during the same day and on the day prior to discrimination. Findings indicated the deleterious effect of racial discrimination (associated with more negative affect) and highlighted the importance of examining youth’s short-term coping in critical developmental years. Findings also showed how messages promote positive youth emotions. However, daily moderating associations differed from prior survey studies, suggesting the importance of examining short-term processes.  相似文献

In the present experiment, we investigated whether pigeons rely exclusively on elemental information or whether they are also able to exploit configural information in apeople-present/people-absent discrimination task. Six pigeons were trained in a go/no-go procedure to discriminate between 800 color photographs characterized by the presence or absence of people. Thepeople-present stimuli were designated as positive, and thepeople-absent stimuli were designated as negative. After training and a subsequent generalization test, the pigeons were presented with both familiar and novel people-present stimuli containing human figures that were distorted in one of seven different ways. All the pigeons learned the initial discrimination and also showed generalization to novel stimuli. In the subsequent test, performance on all types of distorted stimuli was diminished in comparison with that on the intact original pictures from which they had been derived. At the same time, however, peck rates clearly exceeded the level of responding found for regular people-absent stimuli. This result strongly suggests that responding was controlled by both the constituting target components and their spatial relations and, therefore, points to the dual importance of elemental and configural information.  相似文献

The effects of negative instances in the acquisition of the mathematical concepts of commutativity and associativity were examined. Two treatment levels for commutativity (positive instances or positive and negative instances) and the same treatment levels for associativity were crossed to form a 2 × 2 factorial design with 21 subjects per cell. Subjects were undergraduate elementary education majors. Criterion variables were number of correct responses, stimulus intervals, and postfeedback intervals. Results supported the contention that negative instances enhance concept acquisition but also appear to require more time during treatments. No evidence for a transfer effect for negative instances from one concept to another was found.  相似文献

Although most studies of perceptual learning in human participants have concentrated on the changes in perception assumed to be occurring, studies of nonhuman animals necessarily measure discrimination learning and generalization and remain agnostic on the question of whether changes in behavior reflect changes in perception. On the other hand, animal studies do make it easier to draw a distinction between supervised and unsupervised learning. Differential reinforcement will surely teach animals to attend to some features of a stimulus array rather than to others. But it is an open question as to whether such changes in attention underlie the enhanced discrimination seen after unreinforced exposure to such an array. I argue that most instances of unsupervised perceptual learning observed in animals (and at least some in human animals) are better explained by appeal to well-established principles and phenomena of associative learning theory: excitatory and inhibitory associations between stimulus elements, latent inhibition, and habituation.  相似文献

Aitken (1999) argues that, in a simultaneous discrimination, reports of the transfer of value from the positive to the negative stimulus can be more readily explained in terms of an artifact produced by the procedure in which differential inhibition accrues to the negative test stimuli during training, together with stimulus generalization (similarity between the positive and negative stimuli). We argue that (1) there is little evidence for differential inhibition, and it often occurs in the wrong direction; (2) value transfer can be demonstrated when differential value is established to the positive stimuli afterdiscrimination training, when differential inhibition is not likely to be a factor; and (3) on both logical and empirical grounds, stimulus similarity does not provide an adequate account of the transfer of value from the positive to the negative stimulus (i.e., the strongest evidence for value transfer occurs when there is least stimulus similarity). We propose that value transfer occurs whenever there is relatively little experience with the negative stimuli. However, when there is extended experience with the negative stimuli, contrast will be found.  相似文献

Abstract

To determine teachers' perceptions of the likelihood of students' academic and social success in general education settings, 384 teachers responded to 1 of 32 possible case studies describing a student, in which gender, reading achievement, social behavior, and attentiveness were manipulated experimentally. Results showed that, in some instances, teachers used irrelevant information in their predictions (e.g., social behavior influenced academic predictions, reading achievement influenced social predictions). Furthermore, teachers demonstrated gender bias in some instances and appeared to make negative predictions when an ambiguous label explained students' reading problems. The author discusses implications for the inclusion of students with special needs in general education classes.  相似文献

ABSTRACT

Ageism refers to discrimination against individuals based on age, while aging anxiety is defined as fear about getting older. We were interested in whether ageism and aging anxiety had distinct correlates among young adults. The purpose of this study was to explore the effects that knowledge of aging, contact with older adults, fear of death, and optimism have on ageism and aging anxiety in young adults (N = 623). Knowledge of aging and contact with older adults were associated with lower ageism. Aging anxiety was associated with greater fear of death and lower optimism. Results indicate that the positive effects of contact and knowledge on the attitudes of young adults toward the older adult population. Increased education on the aging process and improving quality of contact with older adults could help reduce ageism and ageing anxiety.  相似文献

Background: More than ever before, school principals are dealing with stress and burnout, resulting from increasing role demands and decreasing decision latitude and autonomy. Following the Demand–Support–Constraints model, reasons for stress and burnout can be found in the lack of social support in the environment.

Purpose: This longitudinal study investigates whether changes in social support from colleagues, supervisors and/or the broader community affect levels of principal stress and burnout.

Sample: Approximately 26% of Australia’s school principals took part (N = 3572): primary (n = 2660) and secondary (n = 912) spread across all Australian states and territories. Age ranged between 46 and 55 years, and mean leadership experience was 12 years.

Design and methods: Since stress and burnout are psychological phenomena that develop over time, a longitudinal approach was adopted. Data were collected across four waves, spread over four years, from 2011 to 2014.

Results: It was found that social support predicts decreased stress and in turn burnout in school principals, however differences were found according to the type of social support. The data provide strong evidence for a positive effect of stress on burnout (e.g. the more stress at time 2, the more burnout in principals at time 3) and partial support for indirect negative effects of social support on burnout (e.g. the more support from colleagues at time 2, the less burnout in principals at time 3). However, we also found two instances of positive effects of social support from the broader community on burnout. This suggests that the more support principals receive from the broader community, the more likely they are to show burnout symptoms. This might be explained as the ‘the downside of empathy’, where principals who are strongly supported by their community might also feel more connected to that community. When their community is struggling, they are probably struggling as well.

Conclusions: The findings highlight the positive impact the wider school community can play in providing supplementary professional support to the principal. Unbundling or repackaging the job responsibilities with an administrative team that shares the leadership of the school, could be part of the solution.  相似文献

ABSTRACT

Background: The importance of digital technologies for enhancing learning in formal education settings has been widely acknowledged. In the light of this expectation, it is important to investigate the effects of these technologies on students’ learning and development.

Purpose: This study explores longitudinal empirical research on digital learning in the context of primary and secondary education. By focusing on a small selection of the peer-reviewed literature, the aim is to examine the kinds of longitudinal study published on this topic during the period 2012–2017 and, thorough categorisation, to bring together insights about the reported influences of digital technology use on students’ learning.

Design and methods: The databases searched for the purposes of this review were Scopus and Web of Science. Of 1,989 articles, 13 were finally included in the review. Using qualitative content analysis, these were analysed, coded and categorised.

Results: The reviewed studies were found to have approached digital learning in different ways: they varied, for example, in terms of research methods and design and the digital technologies used. The studies addressed different aspects of learning, which we assigned to six categories: affection, attitude, and motivation; subject-specific knowledge and skills; transversal skills; learning experience; elements of the learning environment; and identity. We identified both positive and negative influences of technology on learning.

Conclusions: This review offers a snapshot of the variety of research in this fast-moving area. The studies we explored were found to approach digital learning from several different perspectives, and no straightforward conclusions can be drawn about the influences of digital technology use on students’ learning. We conclude that further longitudinal studies of digital learning are needed, and this study assists by highlighting gaps in the existing literature.  相似文献

The present study summarized research on school inspection of the last 30 years to provide an estimation of its effectiveness and to identify factors influencing inspection effectiveness. Following a systematic literature search, k = 30 inferential statistical studies on school inspection were coded. Due to the large variety in the analytical strategies used in the studies, the findings were synthesized in a systematic review. Twenty-four percent of the n = 222 effects of the k = 16 control group studies indicated positive and 18 % negative inspection effects. The majority of effects (58 %) was not significant. The most consistent positive inspection effects resulted for standardized achievement tests in Mathematics and in the mother language. Perceived accountability pressure and the perceived quality of the inspection were two of several factors that influenced inspection success in the k = 16 comparison group and correlational studies. The findings highlight new avenues for school inspection research and practice.  相似文献

BackgroundChild sexual abuse (CSA) is a problem with severe consequences for victimized children. A variety of interventions have been developed and implemented over the last decades to prevent CSA. However, most of them have not been systematically evaluated to determine their effectiveness. The IGEL program is a school-based intervention to prevent CSA in third-grade primary school children in Germany.MethodsThis study was conducted using a quasi-experimental design, in which almost 300 children and their parents from eight intervention and four control schools were surveyed three times (pretest, posttest, 3 months later). In order to measure outcomes, a questionnaire was developed based on validated instruments to assess the knowledge, courses of action and self-protective skills of the children. Furthermore, increased anxiety and generalized touch aversion were examined as potentially harmful side effects of the program.ResultsThe results clearly demonstrate increased CSA-related knowledge and courses of action in children from the intervention group compared to the control children. These effects were medium-sized and sustained for at least three months after the last session. No meaningful negative side effects were detected in the evaluation for either the children or parents.ConclusionThe outcome evaluation indicates that the IGEL program is an effective intervention in terms of knowledge about CSA and known courses of action, and may therefore contribute to the prevention of CSA in primary schools. Despite this positive core finding of the intermediate outcomes, some adaptations of the program to children with different cultural backgrounds were made prior to further dissemination.  相似文献

BackgroundChild abuse pediatricians (CAPs) are often consulted for injuries when child physical abuse is suspected or when the etiology of a serious injury is unclear. CAPs carefully evaluate the reported mechanism of the child’s injury and the medical findings in the context of the child’s family and social setting to identify possible risk and protective factors for child abuse and the need for social services. It is unknown what population risk indicators along with other social cues CAPs record in the social history of the consultation notes when assessing families who are being evaluated for child physical abuse.Participants and settingThirty-two CAPs representing 28 US child abuse programs.MethodsParticipants submitted 730 completed cases of inpatient medical consultation notes for three injury types: traumatic brain injury, long bone fracture, and skull fracture in hospitalized children 4 years of age and younger. We defined a priori 12 social cues using known population risk indicators (e.g., single mother) and identified de novo 13 negative (e.g., legal engagement) and ten positive social cues (e.g., competent parenting). Using content analysis, we systematically coded the social history for the social cues.ResultsWe coded 3,543 cues resulting in a median of 7 coded cues per case. One quarter of the cues were population indicators while half of the cues were negative and one quarter positive.ConclusionsCAPs choose a wide variety of information, not always related to known population risk indicators, to include in their social histories.  相似文献

Abstract

Despite Brown vs. Board of Education, prejudice still exists in the American school system. These attitudes can give rise to negative social experiences for students of color (i.e., discrimination), negatively impacting their mental and physical health and creating disparities in educational outcomes. Rather than seeking to ameliorate these negative experiences, our approach attempts to address the underlying prejudices and, in so doing, reduce these disparities. Using 4 waves of data from a cluster randomized trial (N?=?15 middle schools, 1,890 students, 47.1% female, 75.2% White), we hypothesized that cooperative learning, which has been shown to reduce prejudice in previous research, would create positive gains in peer relatedness, perceptions of academic support, and engagement in learning, and that gains would be larger for students of color; our results confirmed these hypotheses. Our findings highlight the potential role of cooperative learning in reducing disparities and creating greater equity in education.  相似文献

Objective. This study examined the cognitive-affective strategies used by parents of young children with conduct problems to regulate emotions. Key questions concerned the extent to which these emotion regulation strategies are associated with positive and negative parenting practices and predict quality of parenting through interplay with parental depression. Design. Participants were families of toddlers (n = 84) referred to a tertiary-level health service for the treatment of disruptive behavior problems. Parenting practices were indexed through observational coding of parent–child interactions and self-report data on multiple dimensions of positive and negative parenting. Parents self-reported their use of cognitive reappraisal and expressive suppression—the two emotion regulation strategies that are most robustly associated with psychosocial functioning in adults. Results. Associations between emotion regulation strategy and quality of parenting were moderated by parental depressive symptom severity, with distinct effects seen for positive and negative parenting practices. In terms of positive parenting, more frequent use of cognitive reappraisal was associated with increased use of labeled praise among parents with lower levels of depressive symptoms, whereas parents who had higher levels of depressive symptoms engaged in less such praise regardless of how frequently they used reappraisal. In terms of negative parenting, frequent use of cognitive reappraisal and expression suppression were associated with reduced levels of negative parenting, but only among parents with high levels of depression. Conclusions. These findings add to growing support for the integration of emotion regulation strategies into family process models of early-onset conduct problems and related clinical interventions.  相似文献

BackgroundNumerous studies over the past two decades have found a link between adverse childhood experiences (ACEs) and worse adult health outcomes. Less well understood is how advantageous childhood experiences (counter-ACEs) may lead to better adult health, especially in the presence of adversity.ObjectiveTo examine how counter-ACEs and ACEs affect adult physical and mental health using Resiliency Theory as the theoretical framework.Participants and settingParticipants were Amazon mTurk users ages 19–57 years (N = 246; 42% female) who completed an online survey.MethodsWe conducted a series of regression analyses to examine how counter-ACEs and ACEs predicted adult health.ResultsCorresponding to the Compensatory Model of Resiliency Theory, higher counter-ACEs scores were associated with improved adult health and that counter-ACEs neutralized the negative impact of ACEs on adult health. Contrary to the Protective Factors Model, there was a stronger relationship between ACEs and worse adult health among those with above average counter-ACEs scores compared to those with below average counter-ACEs scores. Consistent with the Challenge Model, counter-ACEs had a reduced positive effect on adult health among those with four or more ACEs compared to those with fewer than four ACEs.ConclusionsOverall, the findings suggest that counter-ACEs protect against poor adult health and lead to better adult wellness. When ACEs scores are moderate, counter-ACEs largely neutralize the negative effects of ACEs on adult health. Ultimately, the results demonstrate that a public health approach to promoting positive childhood experiences may promote better lifelong health.  相似文献

Objective. The goal of this study was to examine how mothers and fathers contribute to each other’s autonomy supportive and controlling behaviors toward their child. Design. The participants were heterosexual parental dyads from two prospective studies (Study 1, n = 289; Study 2, n = 202). Mothers and fathers completed questionnaires assessing their autonomy supportive and controlling behaviors toward their adolescent child. Results. In both studies, results from structural equation modeling revealed reciprocal partner effects where mothers’ autonomy support at Time 1 predicted fathers’ autonomy support at Time 2, and fathers’ autonomy support at Time 1 predicted mothers’ autonomy support at Time 2. Reciprocal partner effects were also observed for controlling behaviors. These reciprocal relations were not statistically different across mothers and fathers. Conclusions. These results provide support for interparental contributions regarding autonomy supportive and controlling parenting behaviors. Mothers and fathers should thus be aware that their parenting behaviors can be influenced by each other, including both positive and negative parenting behaviors.  相似文献

Ninety-six high-achieving fourth-graders performed a memory task before which either positive or negative expectancy statements were made by an adult and after which either positive or negative feedback statements were given. The resulting dissonant or consonant expectancy-feedback combinations were delivered over a four-day period. Results indicated that for high IQ children, performance was higher for those given discrepant rather than consonant combinations of expectancy-feedback statements. However, for low IQ children, performance was higher when given negative rather than positive feedback regardless of expectancy. The results are discussed in light of an uncertainty theory of motivation and arousal.  相似文献

Differential effects of variety versus repetition in the development of categorization skills were studied with fifty-four 5-year-old Head Start children, using a sequence of programmed booklets to teach a social studies unit on workers.

It was hypothesized that children receiving Intermediate Variety (two categories, twelve instances, presented once) would demonstrate superior performance on transfer to new instances of the trained categories when compared to those trained with Low Variety (two categories, six instances, presented twice). Secondary hypotheses were that children trained with Low Variety would demonstrate superior performance on a mastery test when compared to children receiving Intermediate Variety, and that High Variety (four categories, six instances) would be superior to both Low and Intermediate Variety in transfer to new categories.

By analysis of covariance, scores of the Intermediate Variety treatment were significantly higher (p<.05) on Near Transfer, supporting the hypothesis that children receiving an Intermediate Variety will demonstrate superior performance on the transfer to new instances when compared with those trained on Low Variety. The secondary hypotheses could be neither supported nor rejected on the basis of the data.  相似文献
