Although expressions of facial emotion hold a special status in attention relative to other complex objects, whether they summon our attention automatically and against our intentions remains a debated issue. Studies supporting the strong view that attentional capture by facial expressions of emotion is entirely automatic reported that a unique (singleton) emotional face distractor interfered with search for a target that was also unique on a different dimension. Participants could therefore search for the odd-one out face to locate the target and attentional capture by irrelevant emotional faces might be contingent on the adoption of an implicit set for singletons. Here, confirming this hypothesis, an irrelevant emotional face captured attention when the target was the unique face with a discrepant orientation, both when this orientation was unpredictable and when it remained constant. By contrast, no such capture was observed when the target could not be found by monitoring displays for a discrepant face and participants had to search for a face with a specific orientation. Our findings show that attentional capture by emotional faces is not purely stimulus driven and thereby resolve the apparent inconsistency that prevails in the literature on the automaticity of attentional capture by emotional faces.  相似文献

Spirituality measures often show positive associations with preferred mental health outcomes in the general population; however, research among American Indians (AIs) is limited. We examined the relationships of mental health status and two measures of spirituality – the Midlife Development Inventory (MIDI) and a tribal cultural spirituality measure – in Northern Plains AIs, aged 15–54 (n?=?1636). While the MIDI was unassociated with mental health status, the tribal cultural spirituality measure showed a significant relationship with better mental health status. Mental health conditions disproportionately affect AIs. Understanding protective factors such as cultural spirituality that can mitigate mental health disorders is critical to reducing these health disparities.  相似文献

Coping with old age involves resolving the task of integrity versus despair, which demands a nondefensive confrontation with the inevitability of death. Halakhah (Jewish ethics) also considered this task critical in later years of life, spoke of death's inevitability, and attempted to discourage denial of death. The Jewish approach seems compatible with Butler's concept of life review as a reconciliation with death and a reintegration of one's identity that occurs throughout later years. While the Eriksonian goal is confronting old age with a certain capacity for wisdom, the rabbis maintained that such wisdom must culminate in the creative act of repentance.  相似文献

Several studies have demonstrated that divided attention at encoding significantly reduces memory performance, whereas divided attention at retrieval affects memory performance only minimally. However, the possibility exists that retrieval processes have shown such resilience because the concurrent tasks used have often not been very demanding. To assess this possibility, we used independent manipulations of the concurrent task during either encoding or retrieval that included stimulus-response compatibility and participant- versus experimenter-controlled pace. In addition, we manipulated the distribution of practice that the participants received with the primary and the concurrent tasks. The results replicated and extended those recently reported by Rohrer and Pashler (2003), indicating that although memory performance is negatively affected by divided attention at retrieval, especially with noncompatible stimulus-response mapping in the concurrent task, this effect was much smaller than that at encoding, in line with the asymmetry notion. Furthermore, experimenter versus participant control of the concurrent task had no effect on memory retrieval. Finally, under conditions of equal practice with both the memory and the concurrent tasks, memory retrieval was affected only to a small degree. In contrast to encoding processes, the processes involved in retrieval accuracy appear, in many cases, to be less interrupted by divided attention, although this protection requires substantial resources.  相似文献

Teaching ethics in engineering and computer science: A panel discussion   总被引:1,自引:0,他引:1  
At a conference, two engineering professors and a philosophy professor discussed the teaching of ethics in engineering and computer science. The panelists considered the integration of material on ethics into technical courses, the role of ethical theory in teaching applied ethics, the relationship between cases and codes of ethics, the enlisting of support of engineering faculty, the background needed to teach ethics, and the assessment of student outcomes. Several audience members contributed comments, particularly on teaching ethical theory and on student assessment. This panel discussion took place at a mini-conference, Practicing and Teaching Ethics in Engineering and Computing, held during the Sixth Annual Meeting of the Association for Practical and Professional Ethics, Washington, D.C., March 8–9, 1997. Biographical information on panelists: Charles Glagola is an assistant professor of civil engineering at the University of Florida. He is a registered professional engineer in the states of Florida and Alabama. Before coming to academia, he had extensive industry experience culminating with his owning and operating a construction and engineering firm in Pensacola, Florida. He currently teaches engineering ethics as part of a professional issues course in the Department of Civil Engineering, and a one-hour engineering ethics course that is offered to all engineering students through the College of Engineering. Moshe Kam is professor of electrical and computer engineering at Drexel University. He heads Drexel’s Data Fusion Laboratory which specializes in multisensor systems and robot navigation. His professional interests include detection and estimation, distributed decision making, forensic applications of image processing, and engineering ethics. Michael Loui is professor of electrical and computer engineering and associate dean of the Graduate College at the University of Illinois at Urbana-Champaign. From 1990 to 1991, he served at the National Science Foundation in Washington, D.C. His scholarly interests include computational complexity theory, theory of parallel and distributed computation, fault-tolerant software, and professional ethics. Caroline Whitbeck is a philosopher of science, technology and medicine and is the Elmer G. Beamer-Hubert H. Shneider Professor in Ethics at Case-Western Reserve University. She also directs the WWW Ethics Center for Engineering & Science— http://ethics.cwru.edu— under a grant from the National Science Foundation. The focus of her current work is practical ethics, especially ethics in scholarly and scientific research. Her book, Ethics in Engineering Practice and Research, will appear from Cambridge University Press in winter 1997–98.  相似文献

Three questions are addressed concerning the relationship of Jewish identity to secular achievements. Are the secular achievements of American Jews related at all to the strength of their Jewish identity? Which has a stronger relationship to secular achievement, a religious or an ethnic Jewish identity? Do communal aspects or private, personal aspects of Jewish identity have the stronger relationship to secular achievements? Using the 2000–2001 National Jewish Population Survey, we find that educational attainment, labor force participation, and occupational achievements are related to several expressions of Jewish identity, even after controlling for the traditional sources of variation (age, gender, education, family status). Jewish identity, as expressed in terms of religion, ethnicity, communal commitment, and private attitudes and practices, is related to contemporary Jewish secular achievement, albeit differently for men and women.  相似文献

Wagner's Tristan und Isolde holds a central position in Western music and culture. It is shown to demonstrate consequences of interruption of developmental processes involving the need for recognition of subjectivity, resulting in the collapse of this need into the wish for annihilation of self and other through ‘love–death’ [Liebestod]. A close reading of the musical language of the opera reveals how this interruption is demonstrated, and the consequent location of identity outside of language, particularly suitable for expression in music. Isolde's dynamics are presented as distinct from that of Tristan, and in contrast to other interpretations of Tristan and Isolde's love as an attack on the Oedipal order, or as a regressive wish for pre‐Oedipal union. Isolde's Act I narrative locates the origin of her desire in the protagonists' mutual gaze at a traumatic moment. In this moment powerful and contrasting emotions converge, evoking thwarted developmental needs, and arousing the fantasy of redemption in love–death. By removing the magical elements, Wagner enables a deeper understanding of the characters' positions in relation to each other, each with his or her own needs for recognition and traumatic experiences. These positions invite mutual identifications resulting in rising tension between affirmation of identity and annihilation, with actual death as the only possible psychic solution. The dynamics described in the opera demonstrate the function of music and opera in conveying meaning which is not verbally expressible.  相似文献

Two experiments provide further information on the effects of divided attention (DA) on encoding and retrieval processes. The first experiment examined the effects of decision and motor difficulty of a concurrent reaction time task. A calibration analysis was used in the second experiment to test the hypothesis that shifting attentional emphasis away from encoding to the secondary task reduces the level of processing the to-be-remembered items receive. Overall, the results confirm and extend the conclusions of Craik, Govoni, Naveh-Benjamin, and Anderson (1996) and Naveh-Benjamin, Craik, Guez, and Dori (1998), by pointing to clear differences between encoding and retrieval processes: Encoding is affected by simultaneous task demands, especially those associated with "central" resources involved in conscious decision making, whereas retrieval is obligatory in that it is largely immune to the effects of simultaneous demands. The results of the calibration analysis suggest that one reason for the poorer memory performance as a result of DA at encoding is a qualitative shift to less deep, elaborative strategies.  相似文献

Humans prefer curved visual objects   总被引:1,自引:0,他引:1  
People constantly make snap judgments about objects encountered in the environment. Such rapid judgments must be based on the physical properties of the targets, but the nature of these properties is yet unknown. We hypothesized that sharp transitions in contour might convey a sense of threat, and therefore trigger a negative bias. Our results were consistent with this hypothesis. The type of contour a visual object possesses--whether the contour is sharp angled or curved--has a critical influence on people's attitude toward that object.  相似文献

Very first impressions   总被引:1,自引:0,他引:1  
First impressions of people's personalities are often formed by using the visual appearance of their faces. Defining how quickly these impressions can be formed has critical implications for understanding social interactions and for determining the visual properties used to shape them. To study impression formation independent of emotional cues, threat judgments were made on faces with a neutral expression. Consequently, participants' judgments pertained to the personality rather than to a certain temporary emotional state (e.g., anger). The results demonstrate that consistent first impressions can be formed very quickly, based on whatever information is available within the first 39 ms. First impressions were less consistent under these conditions when the judgments were about intelligence, suggesting that survival-related traits are judged more quickly. The authors propose that low spatial frequencies mediate this swift formation of threat judgments and provide evidence that supports this hypothesis.  相似文献
