Recent theories of attention have proposed that selection history is a separate, dissociable source of information that influences attention. The current study sought to investigate the simultaneous involvement of selection history and working-memory on attention during visual search. Experiments 1 and 2 used target feature probability to manipulate selection history and found significant effects of both working-memory and selection history, although working-memory dominated selection history when they cued different locations. Experiment 3 eliminated the contribution of voluntary refreshing of working-memory and replicated the main effects, although selection history became dominant. Using the same methodology, but with reduced probability cue validity, both effects were present in Experiment 4 and did not significantly differ in their contribution to attention. Effects of selection history and working-memory never interacted. These results suggest that selection history and working-memory are separate influences on attention and have little impact on each other. Theoretical implications for models of attention are discussed. 相似文献

This study investigated the role of individual resources, notably self-efficacy, gratitude, and hope, in subjective well-being of white dormitory students at a historically white institution of higher learning. Using a convenience sample of white students (N?=?227), we tested the role of generalised self-efficacy, gratitude, and hope as indicators of a latent factor, labelled personal resources, in a structural equation model with subjective well-being as the latent output variable, measured by self-esteem and satisfaction with life. Path analyses indicated a reasonable fit between the data and our hypothesised theoretical model which proposed positive relations between levels of generalised self-efficacy, gratitude, dispositional hope, self-esteem and satisfaction with life. White students were psychologically doing well, considering above-midpoint levels obtained for levels of generalised self-efficacy, gratitude, dispositional hope, and satisfaction with life However, scores obtained for self-esteem and adult dispositional hope were below the mid-point and neutral respectively, indicating that White students do not agree that they experience high levels of these two psychological strengths. White female students experienced higher levels of hope, gratitude, and life satisfaction, while no significant gender differences were found for generalised self-efficacy and self-esteem. The results of this study highlight the potential for using psychological strengths to promote well-being in racially diverse students. 相似文献

In their task of creating a style of “Jewish” national art music based on ethnographic research, many of the composers affiliated with the St. Petersburg Society for Jewish Folk Music wrote arrangements of traditional ethnic songs and dances for small chamber ensembles. These works, generally no longer than the duration of a traditional folk melody, and written with the aim of evoking Jewish village folk culture, occupy a genre that I call the “rural miniature”. This genre was popular in Eastern and Central Europe during this period, and was most commonly composed and performed by musicians who conducted ethnographic fieldwork themselves or studied the findings of other ethnographers of music. The rural miniature was a critical art music genre in the development of state and diaspora musical nationalism. Works in the genre assumed a standard role in the chamber music and solo repertoire during the first four decades of the twentieth century. As the genre’s early proponents moved away from their homes and settled throughout the diaspora, however, the continued survival of rural Jewish life appeared increasingly imperilled by urbanization, emigration, and anti‐Semitism. A discussion of Joseph Achron’s “Hebrew Melody” will demonstrate that, with this cultural migration, the ethnographic component of the rural miniature came gradually to be superseded by the aesthetic elements of propaganda and nostalgia, as the genre was appropriated for fictional idealizations of traditional life in the Eastern European shtetl 1 and expressions of a Zionist longing for the biblical Jewish homeland. 相似文献

Abstract This article questions the adequacy of the philosophical category of realism in characterizing Rheticus' endorsement of Copernicus' astronomy. Rheticus and Osiander agree that the human intellect is restricted in its aspirations to truth, resulting in a condition of “causal ignorance” regarding the celestial phenomena on Rheticus' part. Copernicus' pupil advances trust in the most true hypothesis of the motion of the earth without postulating its absolute truth. Causal knowledge waits after Resurrection. In line with Luther's comment on Genesis 1:14, Rheticus ascribes a theological meaningfulness to the pursuit of mathematics, alerting the astronomer to his immortal soul and divine creation. 相似文献

This article examines some of the story conventions of network television news to explain the ways in which healthcare interest groups develop and maintain their presence in this medium—a process that has significant implications for public understanding of healthcare issues, and therefore to bioethics. The article is divided into three sections. The first section focuses on three major normative conventions of television news: adherence to a simple narrative structure, the balance ethic, and avoidance of the “think-piece” and outlines the basic strategies available to interest groups for exploiting these normative conventions. Section two introduces three case studies of organizations and individuals who have run high-profile media campaigns. Section three explores the implications for bioethics of the observations made in this article. 相似文献

The purpose of the study was to evaluate predictors of response and mechanisms of change for the Homework, Organization, and Planning Skills (HOPS) intervention for middle school students with Attention-Deficit/Hyperactivity Disorder (ADHD). Twenty-three middle school students with ADHD (grades 6–8) received the HOPS intervention implemented by school mental health providers and made significant improvements in parent-rated materials organization and planning skills, impairment due to organizational skills problems, and homework problems. Predictors of response examined included demographic and child characteristics, such as gender, ethnicity, intelligence, ADHD and ODD symptom severity, and ADHD medication use. Mechanisms of change examined included the therapeutic alliance and adoption of the organization and planning skills taught during the HOPS intervention. Participant implementation of the HOPS binder materials organization system and the therapeutic alliance as rated by the student significantly predicted post-intervention outcomes after controlling for pre-intervention severity. Adoption of the binder materials organization system predicted parent-rated improvements in organization, planning, and homework problems above and beyond the impact of the therapeutic alliance. These findings demonstrate the importance of teaching students with ADHD to use a structured binder organization system for organizing and filing homework and classwork materials and for transferring work to and from school. 相似文献

To prevent youth violence, the GREAT Families program was implemented with a selective sample of 1,196 families of sixth-grade children from low-income schools in 4 cities making the transition to adolescence. To assess intervention effects, we used pre- and posttest data to estimate a structural model to test the hypothesis that random assignment to the intervention would predict changes in parenting practices, which in turn would predict changes in exposure to violence (i.e., a mediational model). We found that participation in GREAT was significantly related to changes in parenting practices and these changes significantly predicted changes in violence exposure. Furthermore, adolescents who reported greater increases in exposure to violence also tended to experience greater decreases in parental monitoring, discipline, and involvement. Implications for future research and prevention efforts are discussed. 相似文献
