Throughout history, dance has maintained a critical presence across all human cultures, defying barriers of class, race, and
status. How dance has synergistically co-evolved with humans has fueled a rich debate on the function of art and the essence
of aesthetic experience, engaging numerous artists, historians, philosophers, and scientists. While dance shares many features
with other art forms, one attribute unique to dance is that it is most commonly expressed with the human body. Because of
this, social scientists and neuroscientists are turning to dance and dancers to help answer questions of how the brain coordinates
the body to perform complex, precise, and beautiful movements. In the present paper, we discuss how recent advances in neuroscientific
methods provide the tools to advance our understanding of not only the cerebral phenomena associated with dance learning and
observation but also the neural underpinnings of aesthetic appreciation associated with watching dance. We suggest that future
work within the fields of dance neuroscience and neuroaesthetics have the potential to provide mutual benefits to both the
scientific and artistic communities. 相似文献

PTSD symptoms and substance use commonly co-occur, but information is limited regarding their interplay. We used ecological momentary assessment (EMA) to capture fluctuations in PTSD symptoms and drinking within and across days. Fifty Iraq and Afghanistan War veterans completed four daily Interactive Voice Response (IVR) assessments of PTSD and substance use with cell phones for 28 days. The aims of this study were to (1) describe participant compliance and reactions to the protocol and (2) identify participant characteristics and protocol reactions that predict compliance. Protocol compliance was high, with participants completing an average of 96 out of a total of 112 IVR assessments (86%). While some participants perceived that the IVR assessments increased their drinking (21%) and PTSD symptoms (60%), self-report measures showed significant decreases in PTSD symptoms and nonsignificant decreases in drinking over the assessment period. Analyses revealed demographic (e.g., older than 24, full-time employment, more education), clinical (e.g., less binge drinking, less avoidance symptoms), and perceived benefit from participation predicted better protocol compliance. Results can guide future research on participant predictors of compliance with intensive EMA methods. 相似文献

Despite the fact that humans have a deep motivation to pursue and maintain close relationships, little research has examined social relationships from a motivational perspective. In the current paper, we argue that any model of close relationships must simultaneously account for people’s tendencies to both approach incentives and avoid threats in close relationships. To that end, we review research stemming from Gable’s (2006) social and relationship model of motivation on both the antecedents and the consequences of approach and avoidance goal pursuit in the context of close relationships. We conclude with recommendations for future research in this area. 相似文献

Dellantonio, Innamoratia, & Pastore (2012) consider different interpretations of the notion of a boundary, comparing specifically the metaconceptual frameworks of
exclusive and inclusive separation. I elaborate the target article by considering what a shift to the strategy of inclusive
separation entails. Specifically, it is suggested that this shift introduces a greater focus on the process of development,
as well as a consideration of the ambivalence and emergence involved in boundary processes. Poetry is used as an example to
illustrate these qualities of these boundary processes. It is suggested that when reading a poem, within the boundary of the
literal and imagined senses of words productive tensions are created, and often in overcoming those tensions the person can
arrive at overgeneralized, affectively laden meanings which guide future thought, action and behavior. It is suggested that
in everyday life, the cultural construction of feeling follows a similar process, taking on a poetic form. 相似文献

Across three experiments, we explored whether a dog’s capacity for inhibitory control is stable or variable across decision-making contexts. In the social task, dogs were first exposed to the reputations of a stingy experimenter that never shared food and a generous experimenter who always shared food. In subsequent test trials, dogs were required to avoid approaching the stingy experimenter when this individual offered (but withheld) a higher-value reward than the generous experimenter did. In the A-not-B task, dogs were required to inhibit searching for food in a previously rewarded location after witnessing the food being moved from this location to a novel hiding place. In the cylinder task, dogs were required to resist approaching visible food directly (because it was behind a transparent barrier), in favor of a detour reaching response. Overall, dogs exhibited inhibitory control in all three tasks. However, individual scores were not correlated between tasks, suggesting that context has a large effect on dogs’ behavior. This result mirrors studies of humans, which have highlighted intra-individual variation in inhibitory control as a function of the decision-making context. Lastly, we observed a correlation between a subject’s age and performance on the cylinder task, corroborating previous observations of age-related decline in dogs’ executive function. 相似文献

The visual system is exquisitely adapted to the task of extracting conceptual information from visual input with every new eye fixation, three or four times a second. Here we assess the minimum viewing time needed for visual comprehension, using rapid serial visual presentation (RSVP) of a series of six or 12 pictures presented at between 13 and 80 ms per picture, with no interstimulus interval. Participants were to detect a picture specified by a name (e.g., smiling couple) that was given just before or immediately after the sequence. Detection improved with increasing duration and was better when the name was presented before the sequence, but performance was significantly above chance at all durations, whether the target was named before or only after the sequence. The results are consistent with feedforward models, in which an initial wave of neural activity through the ventral stream is sufficient to allow identification of a complex visual stimulus in a single forward pass. Although we discuss other explanations, the results suggest that neither reentrant processing from higher to lower levels nor advance information about the stimulus is necessary for the conscious detection of rapidly presented, complex visual information. 相似文献

Visual working memory (VWM) capacity is reduced in older adults. Research has shown age-related impairments to VWM encoding, but aging is likely to affect multiple stages of VWM. In the present study, we recorded the event-related potentials (ERPs) of younger and older adults during VWM maintenance and retrieval. We measured encoding-stage processing with the P1 component, maintenance-stage processing with the contralateral delay activity (CDA), and retrieval-stage processing by comparing the activity for old and new items (old–new effect). Older adults showed lower behavioral capacity estimates (K) than did younger adults, but surprisingly, their P1 components and CDAs were comparable to those of younger adults. This remarkable dissociation between neural activity and behavior in the older adults indicated that the P1 and CDA did not accurately assess their VWM capacity. However, the neural activity evoked during VWM retrieval yielded results that helped clarify the age-related differences. During retrieval, younger adults showed early old–new effects in frontal and occipital areas and a late central–parietal old–new effect, whereas older adults showed a late right-lateralized parietal old–new effect. The younger adults’ early old–new effects strongly resembled an index of perceptual fluency, suggesting that perceptual implicit memory was activated. The activation of implicit memory could have facilitated the younger adults’ behavior, and the lack of these early effects in older adults may suggest that they have much lower-resolution memory than do younger adults. From these data, we speculated that younger and older adults store the same number of items in VWM, but that younger adults store a higher-resolution representation than do older adults. 相似文献

Efficient processing of the visual world requires that distracting items be avoided, or at least rapidly disengaged from. The mechanisms by which highly salient, yet irrelevant, stimuli lead to distraction, however, are not well understood. Here, we utilized a particularly strong type of distractor—images of human faces—to investigate the mechanisms of distraction and the involuntarily biasing of attention. Across three experiments using a novel discrimination task, we provided new evidence that the robust distraction triggered by faces may not reflect enhanced attraction but, instead, may reflect an extended holding of attention. Specifically, the onset of a task-irrelevant distractor initially impaired target performance regardless of the identity of that distractor (fearful faces, neutral faces, or places). In contrast, an extended period of distraction was observed only when the distractor was a face. Our results thus demonstrate two distinct mechanisms contributing to distraction: an initial involuntary capture to any sudden event and a subsequent holding of attention to a potentially meaningful, yet task-irrelevant stimulus—in this case, a human face. Critically, the latter holding of attention by faces was not unique to fearful faces but also occurred for neutral faces. The present results dissociate attentional capture from hold in another way as well, since the capture occurred regardless of the nature of the distractors, but the extended holding of attention was dependent upon the ongoing distractor context. 相似文献

This paper examines award‐winning Jewish children's literature as a medium to explore how religiosity gets constructed differently for men and women. We analyze three decades of winners of the Sydney Taylor Jewish Book Award, a prestigious annual award given by the Association of Jewish Libraries to an outstanding Jewish children's book. We demonstrate how these award‐winning books produce and perpetuate gendered religious stereotypes that associate men with agency and women with communion. We also show how these books construct images of a “domestic Judaism” for women and a “public Judaism” for men and how women have been symbolically annihilated from the titles and central character roles in these books. Drawing on Cecilia Ridgeway's ( 2011 ) gender‐framing perspective, we argue that the gender stereotypes evident in these books matter to society because they produce and enforce gender inequalities in religiousness. 相似文献

Community scholars increasingly focus on the linkage between residents’ sense of cohesion with the neighborhood and their own social networks in the neighborhood. A challenge is that whereas some research only focuses on residents’ social ties with fellow neighbors, such an approach misses out on the larger constellation of individuals’ relationships and the spatial distribution of those relationships. Using data from the Twin Communities Network Study, the current project is one of the first studies to examine the actual spatial distribution of respondents’ networks for a variety of relationships and the consequences of these for neighborhood and city cohesion. We also examine how a perceived structural measure of cohesion—triangle degree—impacts their perceptions of neighborhood and city cohesion. Our findings suggest that perceptions of cohesion within the neighborhood and the city depend on the number of neighborhood safety contacts as well as on the types of people with which they discuss important matters. On the other hand, kin and social friendship ties do not impact cohesion. A key finding is that residents who report more spatially dispersed networks for certain types of ties report lower levels of neighborhood and city cohesion. Residents with higher triangle degree within their neighborhood safety networks perceived more neighborhood cohesion. 相似文献
