A radical opponent of Western higher education asserts that its pedagogy and content depend on belief in objective truth and knowledge. This epistemology and education are attacked as exclusive and domineering toward women, minorities, and non-Westerners. The critic puts forward a pragmatist epistemology, leading to multi-cultural education aimed at social criticism and personal autonomy. The critic's dialogue with a defender of traditional epistemological ideas provides a critical introduction to the claims justifying many radical criticisms of Western curricula and pedagogy. 相似文献

Two studies were conducted to examine whether attributions made about events may be influenced by individual assumptions regarding causation that are age related. In Study 1, 96 subjects at three age levels (four and five years, eight and nine years, and college students) observed a target actor on videotape select an item from an unseen array, and four other actors either agree (high consensus) or disagree (low consensus) with the choice. Subjects were asked to decide why the actor liked the chosen object best—because of something about the actor (person attribution) or because of something about the item (entity attribution). The results showed that perceived locus of causality shifted from entity to person attributions with age. In addition, subjects at all ages were able to utilize the consensus information when they had no opportunity to form their own impressions about the items in the array. In Study 2, 126 subjects at four age levels (five and six years, seven and eight years, nine and ten years, and high school students) chose an item from among an array for themselves and responded to a person (self)/entity attribution question regarding the locus of their own choice. The entity to person shift with age was again found and was supported by additional measures. The results are discussed in terms of children's causal reasoning capacities and social environmental factors affecting developmental change in social judgments. 相似文献

The effect of sample stimulus presentation time on long-delay matching in highly practiced pigeons was investigated. The birds were found capable of above chance matching performance at a delay of 60 sec provided the sample stimulus was presented for 4 sec or longer. Matching accuracy increased as a negatively accelerated function of sample stimulus presentation time and decreased as a negatively accelerated function of time since the termination of the sample. The rate of forgetting was found to be independent of sample stimulus presentation time. The data were inconsistent with a temporal discrimination interpretation of the effect of presentation time on delayed matching. The data were interpreted as supporting a simple trace strength and decay model of pigeon delayed matching. 相似文献

Personality and coping were specified as predictors of emotional outcomes of a mildly stressful medical procedure. Situation-specific coping was examined in contrast to dispositional coping, and it was tested whether one or the other would mediate the relationship between higher-order personality factors and stress outcomes. Cataract patients (N=110) participated at four measurement points in time during a six-week period surrounding their scheduled surgery. Dispositional coping did not mediate the personality–outcome relationship. In contrast, situation-specific coping acquired a mediator status between personality and adaptational criteria and accounted for independent outcome variance once personality traits were included as predictors in the models. Thus, the data suggest that whether or not coping mediates between personality factors and affective outcomes may be related to the methodological approaches of its operationalization.

Selective breeding of wild rats over many generations on the basis of low or high defensive threat and attack to human approach and contact has produced highly polarized “domesticated” and “wild-type” animals. Because the selection procedure selectively involves these two defense patterns, and these clearly differ in the two groups, it is of interest to determine if other, nonselected, defensive behaviors to threat stimuli also change. “Domesticated” and “wild-type” rats of the thirty-fifth generation were run in a fear defense test battery (F/DTB) to systematically evaluate defensive behaviors to a variety of present threat stimuli. “Domesticated” rats showed reduced avoidance and slower flight speed to an approaching experimenter, reduced jump/startle response to handelap and dorsal contact, less vocalization and boxing to vibrissae stimulation or to an anesthetized conspecific, and reduced defensiveness to an attempted pickup by the experimenter. These results indicate that selective bi-directional breeding for defensive threat and attack to human approach and contact produces group differences in a variety of defensive behaviors, and in defensiveness to stimuli other than those on which the selection was based. © 1994 Wiley-Liss, Inc. 相似文献

Age discrimination at work is a widespread destructive phenomenon that often takes subtle forms. Based on negative stereotypes about older employees, we argue that older employees often experience that they are perceived as less ideal followers than younger employees. We propose that older and younger employees do not differ in what they assume their supervisors expect of an ideal follower (implicit followership theories, IFTs). Thus, we hypothesize that older employees perceive that they compare less favorably to their supervisors' IFTs than younger employees (i.e., worse IFT-fit). This should entail lower quality of the relationship between leader and follower (leader-member-exchange, LMX), which, in turn, should have detrimental effects on employees' health (i.e., burnout) and job attitudes (i.e., job satisfaction, turnover intentions, and identification). We tested our model in a field study with 379 employees. Results differed for ideal and counter-ideal follower attributes. Concerning counter-ideal follower attributes (e.g., being incompetent), age had the proposed negative effect on psychological health and job attitudes that mediated through IFT-fit and LMX. Concerning ideal follower attributes (e.g., thinking ahead), older employees expected their supervisors not only to think less of them than of their younger colleagues, but also expected them to have less demanding IFTs—contrary to our expectations. Employee age was negatively related to psychological health and job attitudes, mediated through lower perceived IFTs, worse perceived appraisal of the actual employee and their joint effects on LMX. 相似文献

5-Hydroxytrypotophan at a dose of 50 mg/kg intraperitoneally (i.p.) sharply increased neural serotonin (5-HT) levels in mink and considerably inhibited that animal's predatory attack on rats. Intraperitoneal injection of 5-HT (10 and 20 mg/kg) did not influence such rat-killing. Neural levels of 5-HT or 5-hydroxyindoleacetic acid (5-HIAA) and subsequent aggression by the predator did not change to any great degree after ingestion of a single meal. Abundance of natural mink food for 3 days was associated with an increased level of 5-HIAA in the lateral hypothalamus and the amygdala as well as with an increased latency to attack and to kill rats. 5-HT seems to represent an endogenous factor that inhibits predatory attack by the mink; this effect appears to function through increased metabolism of 5-HT in some brain regions, which is evident after abundant intake of tryptophan with the natural diet. 相似文献

Social-cognitive theory posits that children learn gender stereotypes through gendered information. The present study examined whether children learn new gender stereotypes from stories when unknown words are linked to a gendered protagonist or context information. In Experiment 1, 40 3- to 6-year-old preschoolers were read stories with either a gendered protagonist embedded within a non-gendered context, or a non-gendered protagonist embedded within a gendered context. In Experiment 2, the same sample of children were read stories with the protagonist and the context displaying congruent or incongruent gender information. Each story featured an unknown activity linked with the stereotypical content. Both experiments indicate that the children rated the activity according to both the gender of the context and of the protagonist; however, the effect of the latter was stronger. In addition, children showed higher interest in the unknown activity if the protagonist’s gender matched their own sex. Thus, gender information in stories influences how children perceive unknown words. 相似文献
