ABSTRACT Two experiments investigated claims for the efficacy of self-deceptive coping (e.g., Sackeim, 1983, 1988). In Study I the performance of self-deceivers on solvable anagrams was found to he remarkably poor relative to that of non-self-deceivers after both groups were exposed to unsolvable problems. The starkly unambiguous failure experience may have precluded self-deception. Therefore, in Study 2 participants were exposed to unsolvable problems either with or without an excuse. Self-deceivers who encountered failure with an excuse subsequently performed much better on the solvable tasks than those without an excuse. These findings suggest that the use of self-deception following threat is constrained by the availability of contextual ambiguity (e.g., excuses). The effect of the excuse was not related to participants' mood or attributions for performance.  相似文献

Scientists of the Human Genome Project tend to rely on three metaphors to describe their work, each of which implicitly tells much the same story. Whether they claim to interpret the ultimate “book,” to fix a flawed “machine,” or to map a mysterious “wilderness,” they invariably cast the researcher as one who dominates and exploits the Other. This essay, which explores the ways such a story conflicts with feminist values, proposes an alternative.  相似文献

A DEVELOPMENTAL DEFICIT IN LOCALIZING OBJECTS FROM VISION   总被引:3,自引:0,他引:3  
Abstract— We describe a college student, A. H., with a developmental deficit in determining the location of objects from vision. The deficit is selective in that (a) localization from auditory or tactile information is intact, (b) A H reports the identity of mislocalized objects accurately, (c) visual localization errors preserve certain parameters of the target location, and (d) visual localization is severely impaired under certain stimulus conditions, but nearly intact under other conditions. These results bear on the representation and processing of location information in the visual system, and also have implications for understanding developmental dyslexia.  相似文献

In 1947 India became independent and at the same time lost a large part of its territory to the newly created state of Pakistan. This new political arrangement was achieved at a terrible cost in terms of human life and suffering. The years up to and immediately following 1947 provoked a debate about national and human identity. Pakistan was founded on the grounds that Muslims could not be safe or prosperous under majority Hindu rule in newly independent India. The new India insisted that she was a secular democracy in which all religious communities could enjoy equal status. The debate is reflected in a number of Hindi‐language novels which deal with this period. The present article is about one of them, written by a member of India's small Shi'ite Muslim community who was also a Marxist. The debate raises issues about human identity which we can now see as being tragically and importantly relevant for contemporary Europe. These issues are not only political but also religious in that they go to the heart of our understanding of what it means to be human beings. The article points to some of these issues and at the same time argues that the novel as a literary form provides a valuable and significant vehicle for their discussion.  相似文献

Behavior analytic evaluation instruments should benefit teacher education programs in assessing: (a) teacher and student interactions in practice teaching settings, and (b) the immediate and long range effects of the teacher training received. Though empirical substantiation remains scarce, such instruments may be designed to foster teacher trainee sensitivity to, and better control of, complex stimulus and response mechanisms which either impede or facilitate learning. This study analyzed one technologically driven Behavior Analysis Strategy and Taxonomy (BEST) and related Temporal Analysis System (TAS) (Hawkins, Sharpe, & Ray, 1994) currently used within one preservice teacher education program. A multiple probe design with experimental and control groups demonstrated the instruments' effects when used as an instructional feedback tool with teachers in training. Findings supported the instruments' use in terms of teacher and student behavior changes demonstrated for the experimental group as compared to a control group not exposed to the instrument. Implications of this technology when applied to teacher education are last described.  相似文献

Investigation of culturally significant English‐Canadian literature suggests a pervasive and persistent preoccupation with the themes of personal, collective and national identity. Detailed exploration of Canadian writers’ treatment of these topics reveals the presence, not only of familiar Judaeo‐Christian elements, but of a pantheon of exotic hidden gods and bizarre supernatural phenomena. It is evident that, to a remarkable degree, Canadian novelists, poets and critics are preoccupied with the sacred and supernatural. Discerning signals of transcendence in a wide variety of unconventional contexts, they encounter the ultimate in the mysterious depths of personal experience no less than in the cold indifference of nature. The self‐definition of Canadian literati in terms more commonly applied to religious virtuosi raises the familiar theme of aesthetes and intellectuals as the contemporary heirs of the priests and prophets of the past. This insight, in turn, suggests a potentially profitable research project linking the Sociology of Religion with the growing field of Cultural Studies.  相似文献

In a series of experiments, the effects of spatial layout on vibrotactile pattern perception were explored by testing the ability to discriminate between two sequentially presented patterns that share active elements in the same spatial locations. Two-dimensional displays were used in order to examine the functional relationship between discrimination performance and patterncommunality, defined as the sharing elements, on different body sites. Accuracy of discrimination judgments was inversely proportional to communality, regardless of the number of pattern elements. For compact arrays fitted to the finger, palm, and thigh, the effects of communality appeared equivalent. The similarity between finger and thigh functions is remarkable, considering the dramatic differences between these sites in receptor components and structure. When these data were compared with those from arrays with distributed contactors, performance was substantially better with well-separated pattern elements. Such findings help to explicate how information from apposed patterns can best be delivered to the skin through tactile communication systems.  相似文献

Subjects can name color words faster than they can name color patches. To account for that effect, a generic model of naming is described which assumes that words access the mental lexicon directly, whereas color patches do so only indirectly via an initial imaginal or semantic representation. However, Lund (1927) reported that the naming advantage for words disappeared when all the items to be named on a page were the same (i.e., they were blocked). In the present study, three experiments are reported that were designed to provide a clearer empirical definition of Lund’s blocking effect and to ascertain the extent to which it requires a modification of the generic model. The blocked lists had 50 items arranged into 10 blocks, with each block homogeneous with respect to color. The block lengths were either all a predictable length of 5 items or they varied randomly from 1 to 9 items. The data indicated the following: (1) The blocking effect occurred even when the task required a full identification of each item, and (2) the blocking effect was confined to within-block transitions. Blocking seemed to eliminate the word advantage by allowing the subject to re-use the lexical entry used for the immediately prior item, which is consistent with the generic model.  相似文献

Humor via the door motif in Native American Indian cultures can be pervasive and perverse. Helping professionals are alerted to down humor as a positive counseling intervention for this population. Background information, possible cautions, and illustrations are offered, with the need for additional empirical support strongly encouraged.  相似文献

This study examined relations among spelling performance and students' beliefs about spelling, including self-efficacy for spelling ability, outcome expectancy for spelling, and attributions for good spelling across grades 4, 7, and 10. Spelling self-efficacy remained relatively constant across grades. Spelling outcome expectancies for adult life and school declined across grades, as did effort and ability attributions for spelling success, with a disproportional decrease in ability attributions between grades 4 and 7. Self-efficacy was the strongest predictor of spelling performance at all grade levels; attribution for ability entered into the regression for grade 4 students, while outcome expectancies for school and writing were more important in grades 7 and 10. Cluster analyses on the grade 10 sample showed that students with high efficacy as spellers and high outcome expectancy of spelling for writing were the best spellers, with the highest performance reserved for those who attributed good spelling more to effort than ability. The impact of spelling instruction on developing beliefs is discussed.  相似文献
