The authors investigate whether need for closure affects how people seek order in judging social relations. In Study 1, the authors find that people who have a high need for closure (NFC) were more likely to assume their social contacts were connected to each other (i.e., transitivity) when this was not the case. In Studies 2 and 3, the authors examine another form of order in network relations--racial homophily--and find that high-NFC participants were more inclined to believe that 2 individuals from the same racial category (e.g., African American) were friends than two racially dissimilar individuals. Furthermore, high-NFC individuals were more likely to make errors when judging a racially mixed group of people; specifically, they recalled more racial homophily (racially similar people sitting closer together) than had actually appeared. 相似文献

Wearable sensors are an integral part of the new telemedicine concept supporting the idea that Information Technologies will improve the quality and efficiency of healthcare. The use of sensors in diagnosis, treatment and monitoring of patients not only potentially changes medical practice but also one’s relationship with one’s body and mind, as well as the role and responsibilities of patients and healthcare professionals. In this paper, we focus on knowledge assessment of the online communities of Fitbit (a commercial wearable device) and the Quantified Self movement. Through their online forums, we investigate how users’ knowledge claims, shared experiences and imaginations about wearable sensors interrogate or confirm the narratives through which they are introduced to the publics. Citizen initiatives like the Quantified Self movement claim the right to ‘own’ the sensor generated data. But how these data can be used through traditional healthcare systems is an open question. More importantly, wearable sensors trigger a social function that is transformative of the current idea of care and healthcare, focused on sharing, socialising and collectively reflecting about individual problems. Whether this is aligned with current policy making about healthcare, whose central narrative is focused on efficiency and productivity, is to be seen. 相似文献

Monogamy is a near universal expectation in intimate relationships in Western societies and is typically defined as sexual and romantic exclusivity to one partner. This research informs the paradox between monogamy intentions and high rates of infidelity. Monogamy maintenance (MM) strategies used in response to relationship threats posed by attraction to extradyadic others were identified and characterized. Across three samples, 741 U.S. adults in intimate relationships completed surveys addressing MM. Twenty‐four strategies emerged in three factors—Proactive Avoidance (of attractive alternatives), Relationship Enhancement, and Low Self‐Monitoring and Derogation (in the face of extradyadic attraction). All MM factors were commonly endorsed, yet were largely unsuccessful at forestalling infidelity. 相似文献

Positron emission tomography studies during speech have indicated a failure to show the normal activation of auditory cortical areas in stuttering individuals. In the present study, P300 event-related potentials were used to investigate possible effects of behavioral treatment on the pattern of signal amplitude and latency between waves. In order to compare variations in P300 measurements, a control group paired by age and gender to the group of stutterers, was included in the study. Findings suggest that the group of stutterers presented a significant decrease in stuttering severity after the fluency treatment program. Regarding P300 measurements, stutterers and their controls presented results within normal limits in all testing situations and no significant statistical variations between pre and post treatment testing. When comparing individual results between the testing situations, stutterers presented a higher average decrease in wave latency for the right ear following treatment. The results are discussed in light of previous P300 event-related potentials and functional imaging studies with stuttering adults.Educational objectives: The reader will learn about and be able to describe the: (1) use of P300 event-related potentials in the study of stuttering; (2) differences between stuttering and non-stuttering adults; and (3) effects of behavioral fluency treatment on cerebral activity in stuttering speakers. 相似文献

Three experiments explored whether hierarchical role and body posture have independent or interactive effects on the main outcomes associated with power: action in behavior and abstraction in thought. Although past research has found that being in a powerful role and adopting an expansive body posture can each enhance a sense of power, two experiments showed that when individuals were placed in high- or low-power roles while adopting an expansive or constricted posture, only posture affected the implicit activation of power, the taking of action, and abstraction. However, even though role had a smaller effect on the downstream consequences of power, it had a stronger effect than posture on self-reported sense of power. A final experiment found that posture also had a larger effect on action than recalling an experience of high or low power. We discuss body postures as one of the most proximate correlates of the manifestations of power. 相似文献

Both sleep spindles and slow oscillations have been implicated in sleep-dependent memory consolidation. Whereas spindles occur during both light and deep sleep, slow oscillations are restricted to deep sleep, raising the possibility of greater consolidation-related spindle involvement during deep sleep. We assessed declarative memory retention over an interval containing a nap and determined spindle density for light and deep sleep separately. In deep sleep, spindle density was considerably higher and showed a strong and robust positive correlation with retention. This relation was absent for light sleep, suggesting that the potentiating effects of spindles are tied to their co-occurrence with slow oscillations. 相似文献

We analysed the organisation of semantic network using associative mechanisms between different types of information and studied
the progression of the use of these associative relations during development. We aimed to verify the linkage of concepts with
the use of semantic associative relations. The goal of this study was to analyse the cognitive ability to use associative
relations between various items when describing old and/or new concepts. We examined the performance of 100 subjects between
the ages of 4 and 7 years on an experimental task using five associative relations based on verbal encoding. The results showed
that children are able to use the five semantic associative relations at age 4, but performance with each of the different
associative relations improves at different times during development. Functional and part/whole relations develop at an early
age, whereas the superordinate relations develop later. Our study clarified the characteristics of the progression of semantic
associations during development as well as the roles that associative relations play in the structure and improvement of the
semantic store. 相似文献
