Pigeons' keypecking was reinforced by food on baseline schedules of multiple variable interval (VI) x VI x and on contrast schedules of multiple VI x VI y. Deprivation of food was varied by maintaining subjects at 75%, 85%, and 95% (+/- 2%) of their free-feeding weights. Positive and negative behavioral contrast were observed. The size of the contrast was not systematically altered by changes in deprivation. Positive and negative contrast were both larger later in the session than they were earlier. Within-session decreases in responding were steeper for the baseline than for the contrast schedules for positive contrast. Within-session decreases were steeper for the contrast than for the baseline schedules for negative contrast. These results were predicted by the idea that different amounts of habituation to the reinforcer during the baseline and contrast schedules contribute to behavioral contrast. The results show that contrast occurs under conditions that reduce the effect of the following component. The results support the assumption that positive and negative contrast are produced by symmetrical theoretical variables. 相似文献

More than 20 years ago, psychologists first described gifted students with learning disabilities (LD). In the past decade, several sets of identification criteria have been proposed for this population. Many of the suggested assessment practices are unsupported by research in psychoeducational assessment, and some have been directly contradicted by recent research. We argue that an uncritical acceptance of the concept of concomitant giftedness and LD has led to unsound identification procedures and to interventions that are not targeted properly. Specific recommendations for future research and implications for current clinical practice are discussed. 相似文献

Self‐Compassion Among College Counseling Center Clients: An Examination of Clinical Norms and Group Differences 下载免费PDF全文
Allison J. Lockard Jeffrey A. Hayes Kristin Neff Benjamin D. Locke 《Journal of College Counseling》2014,17(3):249-259
There has been growing interest in the mental health benefits of self‐compassion. This study was designed to establish norms on the Self‐Compassion Scale–Short Form, a popular measure of self‐compassion for individuals seeking counseling, and to examine group differences in self‐compassion based on gender, race/ethnicity, sexual orientation, previous counseling, and psychiatric medication use. Data for this study were collected through the Center for Collegiate Mental Health, a practice‐research network of more than 240 college and university counseling centers. 相似文献

While most German anatomy institutes provide only limited information about body donors and their lives, students have expressed a desire to learn more about these individuals, especially about their motivations to donate their bodies for the sake of medical education. In order to gratify this wish, as well as to further humanize body donors, an educational film was compiled, and a study designed to capture the film's effects on medical students. This is the first study using standardized, validated psychological tools to evaluate the impact of an educational film about body donors on students’ empathy and psychological stress levels. The study followed a longitudinal, controlled, and cluster randomized design, including 77 (48 females/29 males) participants who watched the video either before, midway, or after the dissection course. Questionnaires were completed at four points in time applying the Jefferson Scale for Empathy (JSPE-S) and the Interpersonal Reactivity Index (IRI) to measure empathy. Psychological stress levels were recorded by the Brief Symptom Inventory (BSI). Overall, students recommended the film to be shown to all students (median 6.0; maximum on the six-point Likert scale). Viewing the film revealed no significant changes between study groups or over time in JSPE-S sum scores. All groups demonstrated a significant reduction of BSI values before the dissection course actually started and increased values during the course, but both developments appeared not to be associated with the intervention. Overall, the educational film did not correlate with any negative effects on students’ empathy and psychological stress levels, and it was strongly approved of by students, as it provided more humanizing personal information about body donors without violating their anonymity. 相似文献

Florida and Puerto Rico Secondary Science Teachers’ Knowledge and Teaching of Climate Change Science
Benjamin C. Herman Allan Feldman Vanessa Vernaza-Hernandez 《International Journal of Science and Mathematics Education》2017,15(3):451-471
Misconceptions about climate change science are pervasive among the US public. This study investigated the possibility that these misconceptions may be reflective of science teachers’ knowledge and teaching of climate change science. Florida and Puerto Rico secondary science teachers who claim to teach extensively about climate change were surveyed in regard to their conceptions of climate change science and the climate change-related topics they teach. Results show that many teachers hold naïve views about climate change (e.g. that ozone layer depletion is a primary cause of climate change) and climate change science (e.g. that it must be based on controlled experiments for it to be valid). In addition, teachers in both groups neglect crucial topics such as how evidence for climate change is developed and the social, political, and economic dimensions of climate change. Our results suggest the need for teachers to understand how to teach climate change and the nature of climate change science using authentic contexts that promote effective socioscientific decision-making and climate change mitigation. 相似文献

AbstractDuring the late-nineteenth century, imperial expansion increasingly produced what Louise Pratt terms ‘contact zones’ – ‘social spaces where cultures meet, clash and grapple with each other, often in contexts of highly asymmetrical relations of power’. Sport was one of the most visible spaces where this process took place. This paper uses the example of cricket in Samoa to demonstrate how different groups sought to control sport’s meaning amidst great uncertainty. Almost as soon as they began playing cricket, Samoans radically altered its method and meaning to create the distinctively Samoan game of kirikiti. This act established the cricket pitch as a ‘contested space’ between Samoans and foreigners, who were wary of kirikiti’s association with Samoan politics and customary exchange. As was the case in Samoa more generally, however, this struggle was not neatly divided between Samoans and foreigners. While missionaries and settlers portrayed the game as a threat, others – notably sailors and proponents of British influence – greeted it with relative enthusiasm. For their part, Samoans used the game to signal alignment with or against one or another Western power. Finally, Samoa’s growing ‘mixed-race’ community saw the game as a means of confirming their place in both the Samoan and European ‘worlds’. 相似文献

AbstractThis paper is based on sociological research on Torcida, football supporters of Hajduk Football Club from Split (Croatia). We used ethnographic methodology throughout 37 months of fieldwork (from July 2012 to August 2015) and conducted 23 in-depth interviews with hardcore members of Torcida. Although our research included the distinction between carnival supporters and hooligans, these elements are much more interconnected within the hard core of Torcida than they are separate. Because of various social efforts (sometimes coordinated with other Ultras groups) against the local and global football establishment – especially against the Croatian Football Federation and UEFA – we consider Torcida part of a wide, heterogeneous social movement against modern football. This corresponds to the self-reflection and self-perception of the core group of Torcida. Ultras subculture in the Croatian context represents a key (although not the only) social actor in bearing the AMF movement. 相似文献
