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

Two contrasted father-mother-infant interactions are observed longitudinally during trilogue play. They illustrate the contribution of recent research to the exploration of triangulation in infancy: namely, the infant's capacity to handle triangular interactions and share her affects with her two parents, and the way that this capacity is recruited in functional versus problematic alliances. It is likely that an infant under stress when interacting with one parent will protest at that parent and also at the other. Such is the case when, for example, the father acts intrusively while playing with his baby. The infant is then driven to avert and turns to the mother. The regulation of this dyadic intrusion-avoidance pattern at family level depends on the family alliance. When coparenting is supportive, the mother validates the infant's bid for help without interfering with the father. Thus, the problematic pattern is contained in the dyad, and the infant's triangular capacities remain in the service of her own developmental goals. But when coparenting is hostile-competitive, the mother ignores the infant's bid or engages with her in a way that interferes with her play with her father. In this case, the infant's triangular capacities are used to relieve the tension between the parents. The importance of tracing family process back to infancy for family therapy is discussed.  相似文献

The hypothalamus pituitary adrenal (HPA)- axis is one of the major output systems of the neuroendocrine stress response. Its major end products, glucocorticoids (GCs), have a plethora of effects throughout the organism, most of which are believed to be protective against disturbances of homeostasis. However, negative effects have also been described under specific conditions of hyper- or hypo(re)activity of the HPA axis. Both beneficial and adverse effects of GCs ultimately depend on the target tissue sensitivity to these steroids. Recent findings suggest that GC sensitivity (a) may vary between different target tissues in the same organism, (b) shows large individual differences and (c) can be acutely changed in times of acute stress. In the present review, data are summarized which show differences in GC sensitivities in patients suffering from diverse somatic and psychiatric diseases, as well as chronically stressed individuals. Furthermore, studies are presented that show a rapid modulation of GC sensitivity in response to exercise or psychosocial stress in healthy adults. The response pattern of acute GC sensitivity modulation seems to be influenced by age and sex hormone status of the individual. While the GC signalling cascade may be subject to modulation at several levels, the pathway for acute modulation of GC sensitivity remains to be elucidated.  相似文献

In 3 experiments, affirmative and hypothetical probes were presented after narrative texts containing conditional arguments. According to the data, readers represented modus ponens deductions as certain, except when it was only a weakly necessary cause of a given effect. They represented any logically invalid inferences resulting from affirming the conditional consequent as hypothetical, except when it was the effect of strongly sufficient cause. Accordingly, readers must be processing conditional syntax as an asymmetric constraint. However, the underlying causal knowledge can be sufficient either to discredit or warrant the inferences. Thus according to the theory of natural logic, readers can draw formal deductions and be convinced of their necessity. This provides further evidence that readers can represent their inferences as hypothetical (N. Campion, 2004).  相似文献

We used electrophysiological methods to track the deployment of visual spatial attention while observers were engaged in concurrent central attentional processing, using a variant of the attentional blink paradigm. Two visual targets (T1, T2) were presented at a stimulus onset asynchrony of either 200 ms or 800 ms. T1 was a white digit among white letters presented on a dark background using rapid serial visual presentation at fixation. T2 was another digit that was presented to the left or right of fixation simultaneously with a distractor digit in the opposite visual field, each followed by a pattern mask. In each T2 display, one digit was red and one was green. Half of the subjects reported the red digit and ignored the green one, whereas the other half reported the green digit and ignored the red one. T1 and T2 were reported in one block of trials, and only T2 in another block (order counterbalanced across subjects). Accuracy of report of T2 was lower at short SOA than at long SOA when both T1 and T2 were reported, but was similar across SOA when only T2 was reported. The electrophysiological results focused on the N2pc component, which was used as an index of the locus of spatial attention. N2pc was reduced in amplitude when subjects reported T1, and particularly so at the short SOA. The results suggest that attention to T1 interfered with the deployment of visual spatial attention to T2.  相似文献
