Literature on the so-called bilingual advantage is directed towards the investigation of whether the mastering of two languages fosters cognitive skills in the non-verbal domain. The present study aimed to evaluate whether the bilingual advantage in non-verbal skills could be best defined as domain-general or domain-specific, and, in the latter case, at identifying the basic cognitive skills involved. Bilingual and monolingual participants were divided into two different age groups (children, youths) and were tested on a battery of elementary cognitive tasks which included a choice reaction time task, a go/no-go task, two working memory tasks (numbers and symbols) and an anticipation task. Bilingual and monolingual children did not differ from each other except for the anticipation task, where bilinguals were found to be faster and more accurate than monolinguals. These findings suggest that anticipation, which has received little attention to date, is an important cognitive domain which needs to be evaluated to a greater extent both in bilingual and monolingual participants. 相似文献

Two forms of competitive encounters namely Randori (free fight) and Kata (highly ritualized fight) were studied in 22 professional male judo fighters. The dyadic, symmetrical (in terms of body weight and fighting ability) encounters were videotaped to assess relationships between agonistic behavior and individual variations in plasma levels of testosterone (T), cortisol (C) and interleukins (IL‐6 and IL‐1β) measured before and after the competition. Unremarkably, winners showed longer attack but devoted less time to defensive behaviors when compared to losers. T increased only during Randori but the individual pre‐ and post‐competition T levels recorded in such fights were strongly correlated with the corresponding measures in the Kata for the same individuals. Interestingly, the pre‐ and post‐Randori competition T levels were higher in losers than in winners and T variations positively correlated with the frequencies of attacks and with the duration of defensive postures. The T response shows individual variation and seems to reflect evaluation of the likelihood of winning or losing. Both Randori and Kata induced a marked C increase, although the pre‐ and post‐Randori hormonal titers were higher than those found for the Kata. IL‐6 significantly increased between the pre‐ and the post‐Randori competition, but no such changes occurred during the Kata. No correlations were found between individual pre‐ and post‐competition C and IL‐6 and IL‐1β levels in either Randori or Kata. This suggests that C and cytokine release are unrelated to emotional or cognitive perception of the possible outcome of fighting but are a consequence of general motor activity. Martial arts appear to provide good human models to understand: (a) the relationships between conflict, hormones and the immune system and (b) the relationships between mood and physiological responses to competitive aggression.

Multiple studies have found that older workers may be disadvantaged in their job search due to explicit age stereotypes. However, no published research has examined the effect of both explicit (conscious) and implicit (unconscious) negative age stereotypes against older workers on hiring decisions. The current study fills this gap by using an experimental design to simultaneously examine how both explicit and implicit age stereotypes affect the evaluation of resumes for older and younger job applicants. Participants completed measures of explicit age stereotypes via a questionnaire and implicit age stereotypes with an Implicit Association Test focused on older and younger working-age people. They then completed a resume screening task that included younger and older potential applicants. Results showed that participants’ explicit age stereotypes positively influenced the evaluation of younger applicants’ resumes but had no significant effect on the evaluation of older applicants’ resumes. Conversely, implicit age stereotypes had a negative effect on the evaluation of older applicants’ resumes but had no significant effect on the evaluation of younger applicants’ resumes. The results suggest that both implicit and explicit age stereotypes may harm older job applicants’ hireablity, but through different pathways. 相似文献

Physiological stress is pervasive in today's society. Its detection is normally performed through several unobtrusive methods, driving both caregivers and patients to take measures to reduce the burden of this condition on human health. Among the methods for assessing stress, exhaled breath analysis represents a non‐invasive, real‐time alternative to classic laboratory tests. Therefore, a literature review was performed to assess the presence of altered parameters, related to psychological stress, in exhaled breath. Most studies in our review measured nitric oxide (NO), whose concentration was often correlated, either positively or negatively, with psychological stress, with reasonable scientific support. Other compounds (isoprene, terpene and so on) were rarely studied and with mixed evidence. Further investigations are needed to elucidate the involvement and the pathophysiological role of NO in stress, possibly including a greater number of individuals, as sample size actually represents the main limitation of the work published to date. 相似文献
