In the aftermath of several school shooting incidents in recent years, students’ perceptions of unsafe schools has been a
major concern for parents, teachers, school officials, school practitioners, and policy-makers. Using Bronfenbrenner’s ecological
systems framework, we examined the micro-, meso-, and exosystem level factors associated with perceptions of unsafe school
environments in a nationally representative sample of 10- to 15-year-old youth in the United States. We found that for the
socio-demographic characteristics, students who were older, male, and poor had increased risks of perceiving higher levels
of unsafe school environments. Within the microsystem of the family, our results indicate that parent-youth discussions of
school activities/events decreased the risk of students perceiving unsafe schools. All of the school environment variables—ease
of making friends, teachers’ involvement, observed weapon carrying, and school rule enforcement—were related in the expected
direction to students’ perceiving their schools as unsafe. At the mesosystem level, findings from our study demonstrate that
variables measuring parental school involvement were unrelated to perceptions of school safety. Finally, at the exosystem
level, we found that students’ perceptions of residing in a safer neighborhood and residence in a non-central city metropolitan
area, compared with a central city, decreased the odds of perceiving school environments as unsafe. School policy and practice
implications are discussed. 相似文献

Parkinson's disease (PD) is a progressive neurodegenerative disease primarily characterised by motor symptoms. However, another feature of PD which is receiving increasing attention is the phenomenon of impulse control disorders (ICDs), such as pathological gambling. To date, research into ICDs in PD has centred on a biomedical model of cause, related to the effects of dopamine replacement therapy. However, there are several areas of discrepancy in the current biomedical account of ICDs in PD. In addition, we argue that social and psychological factors also need to be considered to achieve a more complete understanding of the phenomenon. We present a novel conceptual model which combines biomedical and psychosocial factors in the genesis of ICDs in PD and use the model to identify a number of potential treatment intervention points and to highlight important outstanding questions concerning the inter-relationship between psychosocial and biomedical factors in the genesis of ICDs in PD. 相似文献

Little is known about positive development across the transition from adolescence to young adulthood. The purpose of this paper was to use longitudinal data from a large community sample, the Australian Temperament Project, to investigate prospective associations between positive development at age 19?C20?years and changes in social, health, and behavioral outcomes at 23?C24?years. Data from 890 young adults (61.7% women) were analyzed using path analysis. Emotional health, physical well-being, friendship quality, reduced antisocial behavior, and positive development in young adulthood were predicted by higher levels of positive development in late adolescence, after controlling for baseline levels of respective outcomes, gender, and family socioeconomic status. Parent relationship quality and alcohol use were not significantly predicted. Based on these findings, interventions promoting positive development during adolescence should be investigated as a potential means of yielding positive social, health, and behavioral consequences well into young adulthood. 相似文献

Autobiographical memory research documents increased access in the number of memories recalled by emerging adults (ages 18–25)
with stable, clearly defined self-concepts. Very little research has examined the relationship between self-concept clarity
and the episodic and semantic components of emerging adults’ autobiographical recollections. This study examined the relationship
between episodic and semantic autobiographical memory and self-concept clarity in 100 undergraduate students. Contrary to
previous findings, which indicated that stable self-beliefs may be used to facilitate access to episodic memories, the results
suggested that self-concept clarity may not be associated with memory specificity. Instead, self-concept clarity was associated
with recall of events involving cooperative social interactions. Results further showed that older age was associated with
higher SCC. The implications of these results are discussed within the context of the theoretical literature concerning the
relation between autobiographical memory and the development of the self-concept during emerging adulthood. 相似文献

Choosing and using geospatial displays: effects of design on performance and metacognition 总被引:1,自引:0,他引:1
Interactive display systems give users flexibility to tailor their visual displays to different tasks and situations. However, in order for such flexibility to be beneficial, users need to understand how to tailor displays to different tasks (to possess "metarepresentational competence"). Recent research suggests that people may desire more complex and realistic displays than are most effective (Smallman & St. John, 2005). In Experiment 1, undergraduate students were tested on a comprehension task with geospatial displays (weather maps) that varied in the number of extraneous variables displayed. Their metacognitive judgments about the relative effectiveness of the displays were also solicited. Extraneous variables slowed response time and increased errors, but participants favored complex maps that looked more realistic about one third of the time. In Experiment 2, the eye fixations of undergraduate students were monitored as they performed the comprehension task. Complex maps that looked more realistic led to more eye fixations on both task-relevant and task-irrelevant regions of the displays. Experiment 3 compared performance of experienced meteorologists and undergraduate students on the comprehension and metacognitive tasks. Meteorologists were as likely as undergraduate students to prefer geographically complex (realistic) displays and more likely than undergraduates to opt for displays that added extraneous weather variables. However, meteorologists were also slower and less accurate with complex than with simple displays. This work highlights the importance of empirically testing principles of visual display design and suggests some limits to metarepresentational competence. 相似文献

Objective: To empirically identify the appropriate symptom threshold for hyperactivity-impulsivity for diagnosis of ADHD in adults. Method: Participants were 88 adults (M [SD] age = 41.69 [11.78] years, 66% female, 16% minority) meeting formal DSM-IV criteria for ADHD combined or predominantly inattentive subtypes based on a structured diagnostic interview keyed to DSM-IV (Conners' Adult ADHD Diagnostic Interview for DSM-IV [CAADID]). All participants also completed the Conners' Adult ADHD Rating Scale (CAARS), which was normed on the general adult population and includes subscales for DSM-IV inattentive and DSM-IV hyperactive-impulsive symptoms. A T-score threshold of 65 (at least 1.5 SD above population mean) on the CAARS DSM-IV hyperactive-impulsive dimension was used to identify participants with empirically elevated symptom severity. Results: Of 88 participating adults, 48 (55%) had a T-score of at least 65 (1.5 SD) on the CAARS DSM-IV Hyperactive-Impulsive scale. Of these, only 25 (52%) met the DSM-IV cutoff of six hyperactive-impulsive symptoms on the CAADID. Thus, approximately half of those who reported empirically elevated hyperactive-impulsive complaints on the CAARS did not concurrently meet the six-symptom DSM-IV cutoff on the CAADID. An alternative cutoff of four hyperactive-impulsive symptoms on the CAADID captured 39 (81%) cases identified by the CAARS. Conclusion: In adults, mandating at least six hyperactive-impulsive symptoms excludes a significant percentage (almost half) of adults who are at least 1.5 SD above the population mean on a dimensional measure of hyperactivity-impulsivity. These data provide a compelling basis for lowering the symptom threshold of hyperactivity-impulsivity for adults in the DSM-5. 相似文献

Although the study of brain states is an old one in neuroscience, there has been growing interest in brain state specification owing to MRI studies tracing brain connectivity at rest. In this review, we summarize recent research on three relatively well-described brain states: the resting, alert, and meditation states. We explore the neural correlates of maintaining a state or switching between states, and argue that the anterior cingulate cortex and striatum play a critical role in state maintenance, whereas the insula has a major role in switching between states. Brain state may serve as a predictor of performance in a variety of perceptual, memory, and problem solving tasks. Thus, understanding brain states is critical for understanding human performance. 相似文献

This paper examines the effects of group performance anxiety on the attrition of women and minorities from science, math, and engineering majors. While past research has relied primarily on the academic deficits and lower socioeconomic status of women and minorities to explain their absence from these fields, we focus on the impact of stereotype threat—the anxiety caused by the expectation of being judged based on a negative group stereotype. Using data from the National Longitudinal Survey of Freshmen, our findings indicate that minorities experience stereotype threat more strongly than whites, although women do not suffer from stereotype threat more than men. Our findings also reveal that stereotype threat has a significant positive effect on the likelihood of women, minorities, and surprisingly, white men leaving science, technology, engineering and math majors. 相似文献

This study aims at illustrating the interest of a methodology of exploration of identity dynamics, the IMIS(Zavalloni & Louis-Guerin, 1984), for the elaboration of the professional project. Psychosocial identity is a system of representations of oneself and the world animated by the paradox of being identical and distinct at the same time. This system justifies ways of thought and action, that are retrieved in identity strategies. Action is presented as a medium-term project, endowed with a function of regulation of identity and capability representations that it conveys and validates(Costalat-Founeau, 2008). The project therefore leans upon the cognitive substrate of experience. Action doesn’t follow the project, both are interwoven in a common perspective defined by intentional objectives(Young & Valach, 2006). 相似文献

Sustained treatment attendance has been reported to be poor in publicly funded community-based clinic settings serving children and families. Several child and family characteristics have been shown to predict attendance in community-based care, but virtually no research has been conducted to examine how experiences in care, including psychotherapists' within-session practices, influence client attendance. The goal of this exploratory study was to examine how observed practice within sessions, in particular the extent to which therapists delivered elements consistent with evidence-based practices, impacts total number of sessions attended, while accounting for an array of other potential predictors. Participants include 181 children ages 4-13 and their parents entering a new episode of care for disruptive behavior problems in publicly funded clinics. Data sources include administrative billing records on treatment attendance; coded videotaped treatment sessions; and self-reports from children, parents, and therapists. Results indicate that parent education, service funding source, parent alliance with therapist, and therapist experience predicted number of sessions attended; intensity of evidence-based treatment techniques delivered to children was marginally associated with attendance (p = .059). Implications for improving engagement in community-based care are discussed. 相似文献
