The question of what makes people rise to power has long puzzled social scientists. Here we examined the novel hypothesis that power is afforded to individuals who exhibit prosocial norm violations—i.e., breaking rules for the benefit of others. Three experiments using different methods provide support for this idea. Individuals who deliberately ignored a prohibition to tilt a bus chair (Study 1; scenario) or to close a window (Study 2; film clip) were afforded more power than individuals who obeyed the rules, but only when the norm violation benefited others (i.e., by giving them more leg space or fresh air). Study 2 further showed that this effect was mediated by perceived social engagement, which was highest among prosocial norm violators. In Study 3 (face-to-face), a confederate who stole coffee from the experimenter's desk was afforded more power than a confederate who took coffee upon invitation, but only when he also offered coffee to the participant. We discuss implications for hierarchy formation, morality, and social engagement. 相似文献

The aim of this study was to determine the prevalence of impulse control disorders (ICDs) in morbidly obese individuals. One hundred bariatric surgery candidates were examined using a module of the Structured Clinical Interview for DSM-IV that has been developed for ICDs. Nineteen per cent suffered from at least one current ICD and 27% met the criteria for any lifetime ICD, most frequently skin picking (current, 8%; lifetime, 9%), compulsive buying (current 6%, lifetime 8%), and intermittent explosive disorder (current, 5%; lifetime, 10%). Patients with regular binge eating (N?=?25) reported significantly more often a history of at least one ICD compared with those without binge eating. The results indicate a high prevalence of ICDs among morbidly obese prebariatric surgery patients that are related to regular binge eating. 相似文献

The effects of stress on memory were examined through a study of 33 3 to 12‐year‐old maltreated children removed from their biological parents by the Child Protective Services because of an emergency (acute) or normal (planned) care order. Children's stress levels were rated by a researcher present during the removal and children's memory of the removal investigated at a later time. The type of removal significantly predicted children's level of stress. ‘Acute removal’ children remembered more from high‐stress phases of the removal than the ‘planned removal’ children. All children had more accurate memories of the low‐stress phases. Details remembered were rated as central or peripheral; more central information was recalled than peripheral information. The ‘acute removal’ children recalled more peripheral information from the high‐stress phases of the removal than the low‐stress phases, a difference, which was not present for the ‘planned removal’ children.

The present study investigated early communicative gestures, play, and language skills in children born with family risk for dyslexia (FR) and a control group of children without this inheritable risk at ages 12, 15, 18, and 24 months. Participants were drawn from the Tromsø Longitudinal study of Dyslexia (TLD) which follows children's cognitive and language development from age 12 months through Grade 2 in order to identify early markers of developmental dyslexia. Results showed that symbolic play and parent reported play at age 12 months and communicative gestures at age 15 months explained 61% of the variance in productive language at 24 months in the FR group. These early nonlinguistic measures seem to be potentially interesting markers of later language development in children born at risk for dyslexia. 相似文献

Due to the socio-demographic change in most developed western countries, elderly populations have been continuously increasing.
Therefore, preventive and assistive systems that allow elderly people to independently live in their own homes as long as
possible will become an economical if not ethical necessity. These respective technologies are being developed under the term
"Ambient Assistive Technologies" (AAT). The EU-funded AAT-project Ambient Lighting Assistance for an Ageing Population (ALADIN) has established the long-term goal to create an adaptive system capable of improving the residential lighting conditions
of single living elderly persons also aiming at supporting the preservation of their independence. 相似文献

The issue of the existence of planes—understood as the carriers of a nexus of straight lines—in the monocular visual space of a stationary human observer has never been addressed. The most recent empirical data apply to binocular visual space and date from the 1960s (Foley, 1964). This appears to be both the first and the last time this basic issue was addressed empirically. Yet the question is of considerable conceptual interest. Here we report on a direct empirical test of the existence of planes in monocular visual space for a group of sixteen experienced observers. For the majority of these observers monocular visual space lacks a projective structure, albeit in qualitatively different ways. This greatly reduces the set of viable geometrical models. For example, it rules out all the classical homogeneous spaces (the Cayley-Klein geometries) such as the familiar Luneburg model. The qualitatively different behavior of experienced observers implies that the generic population might well be inhomogeneous with respect to the structure of visual space. 相似文献

Do followers perform better when their leader expresses anger or when their leader expresses happiness? We propose that this depends on the follower's level of agreeableness. Anger is associated with hostility and conflict-states that are at odds with agreeable individuals' goals. Happiness facilitates affiliation and positive relations-states that are in line with agreeable individuals' goals. Accordingly, the two studies we conducted showed that agreeableness moderates the effects of a leader's emotional displays. In a scenario study, participants with lower levels of agreeableness responded more favorably to an angry leader, whereas participants with higher levels of agreeableness responded more favorably to a neutral leader. In an experiment involving four-person teams, teams composed of participants with lower average levels of agreeableness performed better when their leader expressed anger, whereas teams composed of participants with higher average levels of agreeableness performed better when their leader expressed happiness. Team performance was mediated by experienced workload, which was highest among agreeable followers with an angry leader. Besides having important practical implications, the findings shed new light on the fundamental question of how emotional expressions regulate social behavior. 相似文献

Compulsive buying (CB) is characterized by the senseless und uncontrollable acquisition of items. The main focus is on the act of buying and the purchased items are afterwards hardly used or not even at all. The repeated excessive behavior leads to psychological, social and financial problems. In addition to their buying behavior most individuals with CB also suffer from other mental disorders, especially depression, anxiety disorders, personality disorders and impulse control disorders. There is an ongoing discussion about the appropriate diagnosis and currently CB is classified as an impulse control disorder not otherwise specified. In the treatment of CB controlled psychotherapy studies indicated the efficacy of cognitive behavioral therapy while the benefit of pharmacotherapy still needs to be confirmed. Additional research is necessary concerning classification, etiology and the development of differential therapy programs. 相似文献

Previous studies [Marcel, A. J. (1983). Conscious and unconscious perception: Experiments on visual masking and word recognition. Cognitive Psychology, 15(2), 197–237; Wentura, D., & Frings, C. (2005). Repeated masked category primes interfere with related exemplars: New evidence for negative semantic priming. Journal of Experimental Psychology: Learning, Memory, and Cognition, 31(1), 108–120] suggested that repeatedly presenting a masked stimulus improves priming without increasing perceptual awareness. However, neural theories of consciousness predict the opposite: Increasing bottom-up strength in such a paradigm should also result in increasing availability to awareness. Here, we tested this prediction by manipulating the number of repetitions of a strongly masked digit. Our results do not replicate the dissociation observed in previous studies and are instead suggestive that repeating an unconscious and attended masked stimulus enables the progressive emergence of perceptual awareness. 相似文献
