Research has shown that exposure to the national flag alters people's behavior and political and intergroup judgments. In several field studies conducted in an area of France with a strong regional identity, we examined the effect of the presence of the regional flag versus the national flag versus no flag on behaviors. Various situations (e.g., money solicitation, implicit helping behavior, food tasting) were tested in Brittany, on the French west Atlantic coast. Car drivers, passersby in the street, and patrons in bakeries were exposed to no flag versus the French flag versus the Brittany flag held by requesters or presented on a product or on a car. Findings showed that the regional flag increased helping behavior dramatically. Other studies also revealed that the presence of the Brittany flag reduced aggressiveness and influenced preference for food products. The power of a flag as a symbol that could increase in‐group membership is discussed.  相似文献

Although the relationship between age-related cognitive decline and saccadic eye movement (SEM) deficits has been outlined, specific cognitive alterations underlying age-related changes in saccadic performance remain unclear. This study attempted to better understand the nature of aging effects on SEMs. We compared SEMs in younger and older adults in prosaccade (PS) and antisaccade (AS) tasks under gap, step, and overlap conditions. We also examined relationships between these performances and several neuropsychological scores. Twenty-eight younger adults (YA), 24 older adults under 65 years (OA<65) and 24 over 65 years (OA>65) of age completed a neuropsychological evaluation, PS and AS tasks. Our results showed that latencies, AS cost, time to correct AS errors, and uncorrected AS, increased with aging. YA showed higher overlap effects than OA>65 and OA<65. Importantly, correlations and regressions revealed close relationships not only between latencies and processing speed measures but also between the AS cost and the inhibition process measures. Correct saccades and the time to correct AS errors were closely related to the inhibition process and cognitive flexibility measures. These findings suggest that the progressive age-related decline of processing speed and executive attention are associated with, and can be highlighted though SEMs in PS and AS tasks.  相似文献

The research used Foucauldian techniques to explore how counsellors currently working for the NHS construct and manage their professional identities in the face of changes imposed on them by the institution. Semi-structured interviews were carried out with four counsellors and one doctoral student, all with substantial experience working for the NHS. A Foucauldian Discourse Analysis revealed four main subjectivities that were made available; feeling like part of a process at times; the NHS imposes limitations on their practice; feeling able to retain their professional standards despite the limitations and lack of influence; feeling proud of, and satisfied with the work they do. Places in which the participants explored ways of constructing a professional identity were also explored.  相似文献

According to the inhibition-deficit hypothesis age differences in working memory capacity and fluid intelligence have been attributed to a decline in inhibitory efficiency. Conceptualizing inhibition as multifaceted, 88 participants (49 younger and 39 elderly) completed two versions of the negative priming paradigm (identification and localization), and two variants of the directed forgetting paradigm (listwise and itemwise). Two tasks of the Wechsler Intelligence Test with high loadings on general fluid intelligence (Gf) served as validation criteria. Results revealed task-specific and speed-independent inhibitory deficits in the elderly (lower negative priming in both paradigms; more intrusions in the directed forgetting tasks), as well as higher levels of repetition priming. Significant correlations between measures of inhibition and the Wechsler scores were found in both age groups. Results support the view of multiple inhibitory-like capabilities that play a central role in the decline of higher-order cognitive functions in old age.  相似文献

Fin swimming performance can be divided into underwater and surface water races. World records are about 10% faster for underwater swimming vs. surface swimming, but little is known about the advantage of underwater swimming for monofin swimming. Some authors reported that the air–water interface influences the kinematics and leads to a narrow vertical amplitude of the fin. On the one hand, surface swimming is expected to affect drag parameters (cross-sectional area (S) and active drag (AD)) when compared to underwater swimming. On the other hand, the surface swimming technique may also affect efficiency (ηF). The aim of this study is therefore to evaluate and compare drag parameters and efficiency during underwater and surface swimming. To this end, 12 international level monofin swimmers were measured during both underwater and surface swimming. Kinematic parameters (both dimensional and non-dimensional), ηF (calculated according to the Elongated-Body Theory), and AD (computed with Velocity Perturbation Method) were calculated for an underwater and a surface fin swimming trial, performed at maximal speed. As expected, results showed significantly lower velocities during surface swimming vs. underwater  = 2.5 m s−1 vs.  = 2.36 m s−1, p < .01). Velocities during underwater and surface swimming were strongly correlated (r = .97, p < .01). Underwater swimming was also associated with higher vertical amplitudes of the fin compared to surface swimming ( = 0.55 m vs. ) = 0.46 m, p < .01). Length-specific amplitudes (Aunder/Lb) were in the order of 20% during underwater swimming as for undulating fish, and significantly higher than during surface swimming (Asurf/Lb = 17%, p < .01). Efficiency for surface swimming was about 6% lower than for underwater swimming ( = 0.79 vs.  = 0.74, p < .01). This decrease could be associated with an increase in swimming frequency for surface swimming ( = 2.15 Hz vs.  = 2.08 Hz, p < .01). Active drag during surface swimming was about 7% higher than for underwater swimming ( = 78.9 N vs.  = 84.7 N, p < .01). A significantly smaller cross-sectional area for surface swimming ( = 0.053 m2 vs.  = 0.044 m2, p < .01) and higher drag coefficient for surface swimming ( = 0.47 vs.  = 0.69, p < .01) were measured. Finally, correlation between cross-sectional area and vertical amplitude of the fin was reported for both underwater and surface swimming. These results suggest that the performance improvement during underwater swimming is not only linked to a wave drag reduction effect but also to a specific swimming technique due to the free surface.  相似文献

Using the two fundamental dimensions of social judgment, warmth and competence, we show that, contrary to general models of impression formation, negative information on one dimension has positive consequences on the way a target is judged on the other dimension. Participants learned about two groups which were either congruent on warmth and competence (one group high on both and the other low on both) or they were compensatory (one group high on warmth and low on competence, the other high on competence and low on warmth). Our results show that in the compensatory condition, the groups were rated more extremely than in the congruent condition and that this was especially the case for the dimension on which the groups were high. Results are discussed both in terms of how they run counter to traditional theories of impression formation and what they tell us about the fundamental dimensions of social judgment.  相似文献

This study shows that sensory priming facilitates reports of same-modality concepts in an attentional blink paradigm. Participants had to detect and report two target words (T1 and T2) presented for 53 ms each among a series of nonwords distractors at a frequency of up to 19 items per second. SOA between target words was set to 53 ms or 213 ms, with reduced attention expected for T2 under the longer SOA (attentional blink) and for T1 under the shorter SOA (lag-1 sparing). These effects were found but reduced when the sensory modality of the concepts matched that of a sensory stimulation occurring prior to the detection trial. Hence, sensory activation increased report for same-modality concepts. This finding reveals that grounded cognition effects (1) are involved in conceptual processing as soon as a word has reached the point of lexical identification and (2) occur independent of intentional access to sensory properties of concepts.  相似文献

Why does university exposure to a hierarchy‐attenuating (HA) academic major (e.g., social science) lead to a decrease in anti‐egalitarianism and group domination (social dominance orientation, SDO)? The reason for this well‐documented phenomenon remains unclear. In the social sciences, the origins of differences in both behavior and personality are attributed more to social and environmental factors than to genetic ones. We hypothesized that the normative and informational influences of this academic major would lead to perceptions that genes have a less important role than nurture in the shaping of human behavior and personality. Our main hypothesis was confirmed. Decreased SDO among psychology students was mediated significantly by a decrease in belief in genetic determinism, the factor we called “geneticism.” Copyright © 2008 John Wiley & Sons, Ltd.  相似文献
