How we react physiologically to stress has long been considered to have implications for our health. There is now persuasive evidence that individuals who show large cardiovascular reactions to stress are at increased risk of developing cardiovascular disease, particularly hypertension. By implication, low reactivity is protective or benign. However, there is recent evidence that low reactivity may predict elevated risk for a range of adverse health outcomes, such as depression, obesity, poor self-reported health and compromised immunity. In addition, low cortisol and cardiovascular reactivity may be a characteristic of individuals with addictions to tobacco and alcohol, as well as those at risk of addiction and those who relapse from abstinence. Our ideas about reactivity may have to be revised in the light of such findings.  相似文献

The effects of vocal intraverbal training and listener training on the emergence of untrained categorization skills were evaluated. Five typically developing preschool children initially learned to name a number of previously unfamiliar visual stimuli. Each child then received one of two types of training. Intraverbal training involved reinforcing vocally emitted category names by the child in the presence of a spoken exemplar name. Listener training involved reinforcing the selection of visual stimuli by the child in the presence of a spoken category name. A multiple baseline design was used to evaluate the effects of training on each child's intraverbal category naming and stimulus selection. Pre- and posttests were used to assess additional emergent relations. Four of 5 participants did not demonstrate the emergence of any untrained relations. The current findings suggest that additional research is needed to determine the optimal sequencing of conditions in programs designed to teach categorization skills.  相似文献

Previous research has shown that exposure to social information can influence behaviour through the automatic activation of goals. In the first study to examine such influences in a legal setting, an experiment with 104 experienced criminal investigators tested the idea that exposure to occupational norms can activate distinct information‐processing goals. As predicted, exposure to norms associated with efficiency (vs. thoroughness) sped up and reduced the depth of investigators' processing of criminal evidence, thus reducing their openness to sequentially late witness evidence. In addition, the goal activation operated outside investigators' awareness, illustrating the insidious cognitive influence of occupational norms. The results are discussed in terms of practical significance and contributions to the goal activation literature and the applied study of criminal investigations.

In cross‐national studies, mean levels of self‐reported phenomena are often not congruent with more objective criteria. One prominent explanation for such findings is that people make self‐report judgements in relation to culture‐specific standards (often called the reference group effect), thereby undermining the cross‐cultural comparability of the judgements. We employed a simple method called anchoring vignettes in order to test whether people from 21 different countries have varying standards for Conscientiousness, a Big Five personality trait that has repeatedly shown unexpected nation‐level relationships with external criteria. Participants rated their own Conscientiousness and that of 30 hypothetical persons portrayed in short vignettes. The latter type of ratings was expected to reveal individual differences in standards of Conscientiousness. The vignettes were rated relatively similarly in all countries, suggesting no substantial culture‐related differences in standards for Conscientiousness. Controlling for the small differences in standards did not substantially change the rankings of countries on mean self‐ratings or the predictive validities of these rankings for objective criteria. These findings are not consistent with mean self‐rated Conscientiousness scores being influenced by culture‐specific standards. The technique of anchoring vignettes can be used in various types of studies to assess the potentially confounding effects of reference levels. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

The ‘social inclusion’ of young people, particularly those who are ‘not in education, employment or training’, is a contemporary concern in policy discourses. However, it has been argued that the term ‘social inclusion’ is defined by adults and imposed on young people, and there is little understanding of what ‘social inclusion’ means to young people themselves. Using a participatory methodology, this study investigated what ‘being included’ meant to young people. A qualitative approach with a thematic analysis was used to explore the accounts of 11 participants and yielded three main themes. ‘“Acceptance”—the building blocks of inclusion’ reflected the power of interpersonal acceptance in determining young people's sense of inclusion. ‘“Learning why I don't matter”—when power and discourse shape inclusion’ illustrated how social discourses and power dynamics influenced young people's experience of inclusion. ‘“Keeping up or falling behind”—internalising the discourse of inclusion’ reflected how young people internalised some of these societal definitions of inclusion and responded to them. Those who felt ‘accepted’ or ‘included’ in a ‘mainstream’ sense articulated a sense of agency and hope. For those who did not, it appeared that agency dissolved as did a sense of hope for the future. Although the participants negotiated their ‘inclusion’ through close, trusting relationships with others, the application of the societal discourses of inclusion such as productivity, independence and career mindedness had the potential to leave them feeling excluded, isolated and distressed.

Studies in economic decision-making have demonstrated that individuals appreciate social values supporting equity and disapprove unfairness when distributing goods between two or more parties. However, this seems to critically depend on psychological mechanisms partly pertaining to the ingroup-outgroup distinction. Little is known as to what extent economic bargaining can be manipulated by means of psychological interventions such has hypnosis. Here we show that a hypnotic ingroup versus outgroup suggestion impacts the tolerance of unfairness in an Ultimatum Game. Specifically, the ingroup suggestion was associated with significantly greater acceptance rates of unfair offers than the outgroup suggestion, whereas hypnosis alone exerted only small effects on unfairness tolerance. These findings indicate that psychological interventions such as hypnotic suggestion can contribute to ingroup favoritism and outgroup rejection.  相似文献

The mental representation of one's own body does not necessarily correspond to the physical body. For instance, a dissociation between perceived and actual reach-ability has been shown, that is, individuals perceive that they can reach objects that are out of grasp. We presented participants with 3D pictures of objects located at four different distances, namely near-reaching space, actual-reaching space, perceived-reaching space and non-reaching space. Immediately after they were presented with function, manipulation, observation or pointing verbs and were required to judge if the verb was compatible with the object. Participants were faster with function and manipulation verbs than with observation and pointing verbs. Strikingly, with both function and manipulation verbs participants were faster when objects were presented in actual than the perceived reaching space. These findings suggest that our knowledge of the world is implicitly built online through behaviour, and is not necessarily reflected in explicit estimates or conscious representations.  相似文献

Once considered a uniquely human attribute, brain asymmetry has been proved to be ubiquitous among non‐human animals. A synthetic review of evidence of animal lateralization in the motor, sensory, cognitive, and affective domains is provided, together with a discussion of its development and possible biological functions. It is argued that investigation of brain asymmetry in a comparative perspective may favor the link between classical neuropsychological studies and modern developmental and evolutionary biology approaches.

Television viewing by infants has become very common, yet relatively little is known about infants' reactions to video compared to live events. We conducted two experiments in order to compare 9- or 10-month-old infants' behavioral reactions to live events and video presentations of those events. In the first experiment, infants' were shown video and live presentations shown consecutively; their affective reactions were consistent, indicating that video conveys meaning and emotional impact even in infancy. However, infants generally looked longer at, reached more to, showed more interest in, and exhibited more fear to the real stimuli. In a second experiment, infants were shown identical live and video events simultaneously; they looked much longer at the live presentations, further confirming that they distinguished live events from video and preferred to watch real events. Implications for infants' television viewing and the use of video images in infancy research are discussed.  相似文献
