Stereotype threat undermines intellectual performance by triggering a disruptive mental load 总被引:1,自引:0,他引:1

Research on stereotype threat has repeatedly demonstrated that the intellectual performance of social groups is particularly sensitive to the situational context in which tests are usually administered. In the present experiment, an adaptation of the Raven Advanced Progressive Matrices Test was introduced as a measure of cognitive ability. Results showed that individuals targeted by a reputation of intellectual inferiority scored lower on the test than did other people. However, when the identical test was not presented as a measure of cognitive ability, the achievement gap between the target and the control group disappeared. Using heart rate variability indices to assess mental workload, our findings showed that the situational salience of a reputation of lower ability undermined intellectual performance by triggering a disruptive mental load. Our results indicate that group differences in cognitive ability scores can reflect different situational burdens and not necessarily actual differences in cognitive ability. 相似文献

Importance-Performance Analysis (IPA) constitutes an indirect approximation to user's satisfaction measurement that allows to represent, in an easy and functional way, the main points and improvement areas of a specific product or service. Beginning from the importance and judgements concerning the performance that users grant to each prominent attributes of a service, it is possible to obtain a graphic divided into four quadrants in which recommendations for the organization economic resources management are included. Nevertheless, this tool has raised controversies since its origins, referred fundamentally to the placement of the axes that define the quadrants and the conception and measurement of the importance of attributes that compose the service. The primary goal of this article is to propose an alternative to the IPA representation that allows to overcome the limitations and contradictions derived from the original technique, without rejecting the classical graph. The analysis applies to data obtained in a survey about satisfaction with primary health care services of Galicia. Results will permit to advise to primary health care managers with a view toward the planning of future strategic actions. 相似文献

Culicover and Jackendoff have recently described an approach to language representation where semantic structure works, alongside syntax, as a generative system with its own structure and principles of composition. Well-known neurological observations support this view. They show that in the presence of a syntactic impairment, comprehension can take place but only if the sentence's semantic structure is rich enough. This would suggest the existence of syntax-independent semantic combinatorial mechanisms, as Culicover and Jackendoff's model proposes. 相似文献

Levelt (2002) argued that apparent effects of word frequency and age of acquisition (AoA) reported in recent picture naming studies might actually be confounded effects operating at the level of object recognition, rather than relevant to theories of lexical retrieval. In order to investigate this issue, AoA effects were examined in an object recognition memory task (Experiments 1 and 2) and a word-picture verification task (Experiment 3) and compared with those found in naming tasks using the same pictures. Contrary to Levelt's concerns, the results of the three experiments show that the AoA effect on picture naming has a lexical origin and does not simply result from a possible confound of object identification times. 相似文献

It has long been established that there is a linear and positive relationship between relative deprivation and prejudice. However, a recent experiment suggests that the converse of relative deprivation, relative gratification, may also be associated with prejudice (S. Guimond & M. Dambrun, 2002). Specifically, the evidence suggests that the usual test for a linear relationship between relative deprivation-gratification and prejudice might conceal the existence of a bilinear relationship. This function, labeled the V-curve hypothesis, predicts that both relative deprivation and relative gratification are associated with higher levels of prejudice. This hypothesis was tested with a representative sample of South Africans (N=1,600). Results provide strong support for the V-curve hypothesis. Furthermore, strength of ethnic identification emerged as a partial mediator for the effect of relative gratification on prejudice. 相似文献

Coherence is demonstrated for categories with binary products and sums, but without the terminal and the initial object, and without distribution. This coherence amounts to the existence of a faithful functor from a free category with binary products and sums to the category of relations on finite ordinals. This result is obtained with the help of proof-theoretic normalizing techniques. When the terminal object is present, coherence may still be proved if of binary sums we keep just their bifunctorial properties. It is found that with the simplest understanding of coherence this is the best one can hope for in bicartesian categories. The coherence for categories with binary products and sums provides an easy decision procedure for equality of arrows. It is also used to demonstrate that the categories in question are maximal, in the sense that in any such category that is not a preorder all the equations between arrows involving only binary products and sums are the same. This shows that the usual notion of equivalence of proofs in nondistributive conjunctive-disjunctive logic is optimally defined: further assumptions would make this notion collapse into triviality. 相似文献

When viewing a rapid sequence of pictures, observers momentarily understand the gist of each scene but have poor recognition memory for most of them (M. C. Potter, 1976). Is forgetting immediate, or does some information persist briefly? Sequences of 5 scenes were presented for 173 ms/picture; when yes-no testing began immediately, recognition was initially high but declined markedly during the 10-item test. With testing delays of 2 or 6 s, the decline over testing was less steep. When 10 or 20 pictures were presented, there was again a marked initial decline during testing. A 2-alternative forced-choice recognition test produced similar results. Both the passage of time and test interference (but not presentation interference) led to forgetting. The brief persistence of information may assist in building a coherent representation over several fixations. 相似文献

Vocal dialogues of 3-month-old infants with their mothers and fathers were recorded during dyadic interactions in the laboratory. Six-minute speech samples were analyzed for syntacticlexical and temporal-melodic features. Both parents adopted strikingly similar speech registers. Segmentation, reduction in syntactic complexity, repetitiveness, and slow tempo were more marked than reported for parental speech to children above 1 year. However, rather than providing proper linguistic models, parents utilized simplified patterns of expressive melodic contours as the most salient units of speech. This tendency is interpretable as age-specific adjustment to infants' integrative capacities. Structural similarities between maternal and paternal baby talk by far outweighed a few quantitative differences. The intuitive nature of recourse to basic nonverbal properties of vocal communication, together with universality across sex, favors the assumption that baby talk is a part of species-specific didactic support to infant communicative development. 相似文献

If confrontation with danger is related to fear, and fear is considered to be the motivation for avoidance behavior, the question remains why certain people seek confrontations with danger. The present study, part of a larger one, is concerned with confrontation with actual danger, as in dangerous sports or voluntarily chosen dangerous professions. It reports the results of interviews with six stunt men. These results partly support the hypothesis of Zuckerman on sensation-seeking personality features: The subjects appear to be eager for varied experience and relatively unconcerned with negative consequences of their actions. The ability to stand the strains and to concentrate under riskful conditions shows up as a further important characteristic of stunt men. The major reward that constitutes the motivation for engaging in the stunting profession appears to consist of being able to meet the challenges involved, with increased self-esteem, receiving acclaim, and monetary profit as secondary rewards. Ability and motivation thus are inextricably intertwined.With acknowledgment to Prof. Nico Frijda, without whose support this article would not have been written and would not have acquired its present form. 相似文献

This study aimed to investigate the development of the group process through group climate parameter dynamics during long-term psychodynamic group psychotherapy for 30 outpatients with psychosis. The group process in four groups was monitored using MacKenzie’s Group Climate Questionnaire-Short Form (GCQ-S) that was completed by the therapist after each session over the two-year period. The trends of engagement, avoidance and conflict parameters differed between groups, and no clear indicators of the development phases were found. The results suggested that these groups remained in the first developmental phase during the observation period, and highlighted the characteristics of resistance and difficulties in establishing social relations in patients with psychosis. 相似文献
