An analysis of the top 100 domestic grossing films of 2002 found evidence of a lingering double standard for aging female and male characters. Overall, major male characters outnumbered major female characters (73% vs. 27%); the majority of male characters were in their 30s and 40s, and the majority of female characters were in their 20s and 30s. Both women and men in their 60s and older were dramatically underrepresented compared to their representation in the US population. For male characters, leadership and occupational power increased with age. Men in their 40s, 50s, and 60s were more likely to play leadership roles and wield occupational power than were their female counterparts. As female characters aged, they were less likely to have goals.  相似文献

A pure tone changing continuously in intensity shows sweep-induced fading (SIF) of loudness as intensity sweeps down and may show a lesser degree of sweep-induced enhancement (SIE) as intensity sweeps up (Canévet & Scharf, 1990); the former effect has been calleddecruitment, the latterupcruitment. An opposite effect—upsweeps being judged to show more loudness change than downsweeps—has been reported by Neuhoff (1998). These disparate results might stem from several procedural differences. We found that differences in the sweep’s duration and intensity level did not account for the disparity, nor did the presence of a steady tone preceding the sweep. In a second experiment, direct judgments of sweep size, such as those Neuhoff’s (1998) listeners made, were affected not only by sweep size itself, but also by the intensity at the end of the sweep. The latter effect was especially marked for upsweeps. Neuhoff’s (1998) proposed “bias for rising intensities” was found only with a method for judging sweep size that is more sensitive to end level than to sweep size.  相似文献

Abstract. Finding themselves teaching to increasingly diverse student populations, two mid‐career faculty from different disciplines embarked on a common voyage to make their foundational courses more sensitive to student learning styles. Adrift in the seas of multiple intelligences and multiculturalism, the researchers quickly abandoned any hope of developing distinctive teaching portfolios for individual learning profiles. Instead, they structured the syllabus to be the passport into a common culture of teaching and learning in the classroom. Syllabus design and on‐going “spot” assessments proved trusty guides in re‐centering learning on the students' needs. In the process of outlining these two strategies for creating a common culture of teaching and learning, the article offers testimony that old dogs can learn new tricks! Additional materials, including syllabi used in these courses and in class assessment tools, can be found on the Web page of the Wabash Center for Teaching and Learning in Theology and Religion: http://www.wabashcenter.wabash.edu/journal/green&stortz.html  相似文献

Previous experiments have demonstrated that the rat dorsomedial striatum is one brain area that plays a crucial role in learning when conditions require a shift in strategies. Further evidence indicates that muscarinic cholinergic receptors in this brain area support adaptations in behavioral responses. Unknown is whether specific muscarinic receptor subtypes in the dorsomedial striatum contribute to a flexible shift in response patterns. The present experiments investigated whether blockade of M1-type and/or M4-type cholinergic receptors in the dorsomedial striatum underlie place reversal learning. Experiment 1 investigated the effects of the M1-type muscarinic cholinergic antagonist, muscarinic-toxin 7 (MT-7) infused into the dorsomedial striatum in place acquisition and reversal learning. Experiment 2 investigated the effects of the M4-type muscarinic cholinergic antagonist, muscarinic-toxin 3 (MT-3) injected into the dorsomedial striatum in place acquisition and reversal learning. All testing occurred in a modified cross-maze across two consecutive sessions. Bilateral injections of MT-7 into the dorsomedial striatum at 1 or 2 microg, but not 0.05 microg impaired place reversal learning. Analysis of the errors revealed that MT-7 at 1 and 2 microg significantly increased regressive errors, but not perseverative errors. An injection of MT-7 2 microg into the dorsomedial striatum prior to place acquisition did not affect learning. Experiment 2 revealed that dorsomedial striatal injections of MT-3 (0.05, 1 or 2 microg) did not affect place acquisition or reversal learning. The findings suggest that activation of M1-type muscarinic cholinergic receptors in the dorsomedial striatum, but not M4-type muscarinic cholinergic receptors facilitate the flexible shifting of response patterns by maintaining or learning a new choice pattern once selected.  相似文献

Although most adults are considered experts in face recognition, brain trauma can produce a selective loss in this ability, a condition referred to as prosopagnosia. This study examined the processing strategies of prosopagnosic patients LR and HH using the Face Dimensions Test. In this test, featural and configural information in the upper and lower halves of the face was parametrically varied and sensitivity to these changes measured. We found that relative to age‐matched control participants, LR and HH exhibited an impaired ability to discriminate differences in the eye region, but a preserved ability to detect featural and configural differences in the mouth region. This pattern of impairment and sparing was demonstrated in tests of direct perception and immediate memory. The obtained findings demonstrate that prosopagnosia does not necessarily cause a global impairment to face perception, but a selective impairment to the perception of information in the upper half of the face.  相似文献

The charitable choice provision and President Bush's proposed Faith-Based and Community Initiative have spurred debates regarding government support of faith-based social service programs and their effectiveness. To address the issue of relative effectiveness, the logically prior question of what constitutes a faith-based agency and how they differ from secular providers must be answered. Utilizing data from a mailed survey, this study compares the organizational characteristics of faith-based and secular agencies that provide services to the homeless in Houston, Texas. Results indicate that the two agency types vary significantly across several dimensions including funding sources and preferences, decision-making tools, organizational culture, practices, leadership, and staffing characteristics. In addition, survey data and content analysis of mission statements reveal that 80 percent of faith-based agencies use religious imagery in some form of their "public face" to communicate their religiousness.  相似文献

This paper explores why respondents to a telephone public-opinion survey often give reasons for answering as they do, even though reason-giving is neither required nor encouraged and it is difficult to see the reasons as attempts to deal with disagreement. We find that respondents give reasons for the policy claims they make in their answers three times as frequently as they give reasons for value or factual claims, that their reasons tend to involve appeals to personal experience, and that they often talk about their thought processes, especially when the evidentiary stakes are high. We then explore several ways of explaining these findings. We suggest that one useful approach is to see the reason-giving in the survey interviews as deliberative, reflexive argumentation of the sort described as `critical thinking. We further suggest that the reason such argumentation is often conducted out loud in the interviews, rather than internally, is that it functions in the service of rhetorical ethos, in particular the need to display the fact that one is human, with human autonomy and agency. Doing this may be particularly important in contexts such as anonymous survey interviews in which people are at risk of being treated like machines.  相似文献
