I combine sociological and economic research to test a new theoretical model of the causes and consequences of teacher responses to students’ track location. I examine the impact of teacher reward structures on educational inequality by analyzing how grading practices affect students’ effort and achievement across tracks. Differences in grading practices determine incentive structures for student behavior and educational investments and thus may be an important mechanism in explaining track effects on academic achievement. I apply student fixed effects models across tracks to the NELS:88 and find that, first, track placement affects achievement, second, although grading practices affect achievement, they only explain a minor part of the track effect, and, third, teacher expectations and perceived class ability level explain the positive track effect for high-track students. These findings suggest that high-track students have higher achievement because their teachers perceive them as better students.  相似文献

The purpose of this paper is to serve as a primer for those who have never used, or even considered using, secondary data as a resource for psychological research. Secondary data (SD) can provide a unique methodological tool with which to examine psychological issues and can serve as a valuable contribution to a program of research. However, this important resource may often be overlooked because its use can sometimes appear daunting and time‐consuming. We seek to assist new users of SD by describing the process in a step‐by‐step manner. We address both benefits and challenges to anticipate when using SD, and discuss identifying and acquiring potential datasets, creating a personalized dataset, variable creation, statistical considerations, and the potential problem of conflicting findings when large datasets are used by multiple researchers. Our goal is to encourage researchers who are novices to the approach to consider using SD as an adjunct to their program of research.  相似文献

The present study assessed direction discrimination with moving random-dot cinematograms at retinal eccentricities of 0, 8, 22, and 40?deg. In addition, Landolt-C acuity was assessed at these eccentricities to determine whether changes in motion discrimination performance covaried with acuity in the retinal periphery. The results of the experiment indicated that discrimination thresholds increased with retinal eccentricity and directional variance (noise), independent of acuity. Psychophysical modeling indicated that the results for eccentricity and noise could be explained by an increase in channel bandwidth and an increase in internal multiplicative noise.  相似文献

Musculoskeletal pain impacts upon everyday life. A degree of chronicity may pose an increased risk of sickness absence. One of two rehabilitative interventions, “Tailored Physical Activity” or “Chronic Pain Self‐Management Program”, was offered to sick‐listed citizens who experienced pain. The objectives of this paper were to: (1) Assess what factors are experienced as problematic for sick‐listed citizens in everyday life with chronic pain, and (2) Evaluate the significance of two distinct rehabilitative interventions on the future everyday lives of sick‐listed citizens. Seven semi‐structured interviews with sick‐listed citizens were analyzed using a phenomenological‐hermeneutical approach. Results were discussed by applying the theoretical framework of Antonovsky's salutogenetic model and Yaloms principles for group psychology. The potential for development of citizen's coping is evaluated based on Roessler's notion of progression. The analysis revealed four main themes: (1) Living with pain and unemployment; (2) “Putting my foot down” and “asking for help”; (3) Significance of the group, including instructors, and; (4) Aspects significant to progression. Unemployment is a major life event that promotes stress and can be accompanied by problems related to depressed mood, acceptance of the life situation, feelings of not being useful, feelings of losing control and identity conflicts. Group characteristics that gave a significant basis for progression in the self‐management program are both emotional and instrumental, while the physical training program offers a “here‐and‐now”‐experience and motivation to participate. This study indicates that the self‐management program could potentially improve coping while the physical activity program revealed one example of a means of progression.  相似文献

The effects of a background scene on the perception of the trajectory of an approaching object and its relation to changes in angular speed and angular size were examined in five experiments. Observers judged the direction (upward or downward) of two sequentially presented motion trajectories simulating a sphere traveling toward the observer at a constant 3-D speed from a fixed distance. In Experiments 14, we examined the effects of changes in angular speed and the presence of a scene background, with changes in angular size based either on the trajectories being discriminated or on an intermediate trajectory. In Experiment 5, we examined the effects of changes in angular speed and scene background, with angular size either constant or consistent with an intermediate 3-D trajectory. Overall, we found that (1) observers were able to judge the direction of object motion trajectories from angular speed changes; (2) observers were more accurate with a 3-D scene background, as compared with a uniform background, suggesting that scene information is important for recovering object motion trajectories; and (3) observers were more accurate in judging motion trajectories based on angular speed when the angular size function was consistent with motion in depth than when the angular size was constant.  相似文献

Image induction posits that social influencers can manipulate a target's self-image to gain increased compliance. By preceding a request with a question that creates a salient self-image in a target, targets are more likely to behave consistently with that image by complying with the request. Three studies provide empirical tests of image induction. Results indicate that the addition of an image-inducing pretreatment question is associated with increased rates of compliance when compared to a control group. These findings held across two types of image induction manipulations (helpfulness, willingness to try new things), two types of behaviors (agreeing to complete a survey, agreeing to receive a free soft drink sample), and both face-to-face and written requests.  相似文献

Abstract

Rescue tasks under heavy strain may act as traumatic events creating stress reactions among the rescue workers. After a major rail accident the rescue workers were examined by questionnaire at 3 and 7 months postaccident using the General Health Questionnaire-28 (GHQ), Impact of Event Scale (IES) and a structured questionnaire made for the purpose. Eighteen percent of the 77 rescue workers who participated in the study had GHQ-case-score and 10% had IES-case-score at 7 months using the usual GHQ-cut-off (4/5) and a low IES-cut-off (19/20). For the case-scorers there was a tendency towards increased GHQ- and IES-scores from 3 to 7 months. Five (6%) had post-traumatic stress disorders (PTSD) of low to moderate severity at 7 months.  相似文献

The aim of this study was to examine the factor structure of the Strengths and Difficulties Questionnaire (SDQ) using a Structural Confirmatory Factor Analytic approach. The Danish translation of the SDQ was distributed to 71,840 parents and teachers of 5–7 and 10–12-year-old boys and girls from four large scale cohorts. Three theoretical models were examined: 1. a model with five first order factors (i.e., hyperactivity/inattention, conduct, emotional, peer problems and prosocial), 2. a model adding two internalising and externalising second order factors to model 1, and 3. a model adding a total difficulties second order factor to model 1. Model fits were evaluated, multi-group analyses were carried out and average variance extracted (AVE) and composite reliability (CR) estimates were examined. In this general population sample, low risk sample models 1 and 2 showed similar good overall fits. Best model fits were found when two positively worded items were allowed to cross load with the prosocial scale, and cross loadings were allowed for among three sets of indicators. The analyses also revealed that model fits were slightly better for teachers than for parents and better for older children than for younger children. No convincing differences were found between boys and girls. Factor loadings were acceptable for all groups, especially for older children rated by teachers. Some emotional, peer, conduct and prosocial subscale problems were revealed for younger children rated by parents. The analyses revealed more internal consistency for older children rated by teachers than for younger children rated by parents. It is recommended that model 1 comprising five first order factors, or alternatively model 2 with additionally two internalising/externalising second order factors, should be used when employing the SDQ in low risk epidemiological samples.  相似文献

Abstract

This study is a content analysis and follow‐up of thirty‐two former participants in multi‐modal expressive therapy training workshops conducted by the Person‐Centered Expressive Therapy Institute. The theoretical foundation of the study is based on Carl Rogers’ concept of the “significant learning” and Natalie Rogers’ concept of the “creative connection.” The expressive therapy applies core conditions of acceptance, empathic understanding, and congruence in a learning setting that uses writing, visual arts, drama, music and dance. Narratives of significant incidents were analyzed phenomenologically. Results revealed important learnings and shifts of self‐perceptions towards greater self‐awareness, improved self‐confidence, risk‐taking, deeper self‐exploration and appreciation for the process involved in the creative act. This qualitative study shows expressive therapy as making an important contribution to person‐centered theory and practice.  相似文献

ABSTRACT

Based on data from the Danish part of the European Values Study 1981–2008, this article explores the validity of the claim for a spiritual revolution as proposed by Paul Heelas and Linda Woodhead. The article suggests an operationalisation of spirituality. The results of the analyses are that religious values—Christian faith as well as spirituality—tend to be stable over an individual’s life course. This suggests that, if there is a spiritual revolution, it must be the product of cohort replacement. If a spiritual revolution is taking place, Christian faith would be expected to decline in younger cohorts while spirituality would increase, but an analysis of cohort support for Christian faith and spirituality from 1981 to 2008 shows that both were constant across cohorts. Thus Danish data contain no indication that a spiritual revolution is taking place or will take place. Finally, we show that, contrary to theoretical expectations, spirituality and Christian faith are strongly correlated. A closer analysis reveals an indirect and more complicated support for parts of the theory since the two variables are explained by different factors and it shows that Christian faith, but not spirituality, is correlated with morality.  相似文献
