Social identity research on crowds demonstrates how cognitive self-definition as a crowd member results in conformity to identity-relevant norms. Rather less research has addressed the social-relational changes within a crowd and how these impact collective experience positively. The present study investigates these processes at a month-long mass gathering in India. Analysis of 37 interviews with participants attending the annual Magh Mela pilgrimage evidences the concept of shared identity as underpinning their understanding of this mass gathering. Moreover, a theoretically derived thematic analysis of these interviews shows the value of the analytic concepts of recognition, validation, and solidarity in illuminating the ways in which social relations in the crowd were experienced and contributed to the experience of the event. Through exploring the multi-dimensional nature of relational connectedness in crowds we contribute to an understanding of crowd experience and group processes.  相似文献

This article features nine ‘narratives of experience’ illustrative of academics engaged in an alternative Professional Development (PD) activity, referred to as Writing for Publication, in a regional Australian university. Each narrative adopts a critical stance to academic practice situated in what Ball defines as a ‘culture of performativity’ perpetuated by a ‘global neoliberal environment’. Contrary to professional development built primarily around sporadic content-provision and credential-based activities, Writing for Publication represents an alternative approach to professional development, a loose-coupling model, that gives validation to academics engaged in navigating dominant neoliberal discourses driving higher education filtered through the interstices or sites for identity-creation, agency formation and emerging communities of practice.  相似文献

The main functions of olfaction relate to finding food, avoiding predators and disease, and social communication. Its role in detecting food has resulted in a unique dual mode sensory system. Environmental odorants are ‘smelled’ via the external nostrils, while volatile chemicals in food—detected by the same receptors—arrive via the nasopharynx, contributing to flavor. This arrangement allows the brain to link the consequences of eating with a food's odor, and then later to use this information in the search for food. Recognizing an odorant—a food, mate, or predator—requires the detection of complex chemical blends against a noisy chemical background. The brain solves this problem in two ways. First, by rapid adaptation to background odorants so that new odorants stand out. Second, by pattern matching the neural representation of an odorant to prior olfactory experiences. This account is consistent with olfactory sensory physiology, anatomy, and psychology. Odor perception, and its products, may be subject to further processing—olfactory cognition. While olfactory cognition has features in common with visual or auditory cognition, several aspects are unique, and even those that are common may be instantiated in different ways. These differences can be productively used to evaluate the generality of models of cognition and consciousness. Finally, the olfactory system can breakdown, and this may be predictive of the onset of neurodegenerative conditions such as Alzheimer's, as well as having prognostic value in other disorders such as schizophrenia.

The impact of community stigmatisation upon service usage has been largely overlooked from a social identity perspective. Specifically, the social identity‐mediated mechanisms by which stigmatisation hinders service use remain unspecified. The present study examines how service providers, community workers and residents recount their experience of the stigmatisation of local community identity and how this shapes residents' uptake of welfare, education and community support services. Twenty individual and group interviews with 10 residents, 16 community workers and six statutory service providers in economically disadvantaged communities in Limerick, Ireland, were thematically analysed. Analysis indicates that statutory service providers endorsed negative stereotypes of disadvantaged areas as separate and anti‐social. The awareness of this perceived division and the experience of ‘stigma consciousness’ was reported by residents and community workers to undermine trust, leading to under‐utilisation of community and government services. We argue that stigmatisation acts as a ‘social curse’ by undermining shared identity between service users and providers and so turning a potentially cooperative intragroup relationship into a fraught intergroup one. We suggest that tackling stigma in order to foster a sense of shared identity is important in creating positive and cooperative service interactions for both service users and providers.

Children may be prepared to associate adult disgust reactions with adult disgust elicitors. To test this, three-year olds (and adults) were presented with two images and an emotive vocalization. The images and vocalizations included stimuli adults found disgusting, fear-provoking, and sad. On one set of trials, the main dependent variable (DV) was time spent looking at each image and on a second set of repeat trials the DV was knowledge of image-sound matches. Fear and disgust vocalizations were both more effective at orienting a child's attention to adult fear and disgust images, than sad vocalizations. Parental disgust sensitivity was associated with this effect, moderated by explicit matching knowledge. Matching knowledge was poor in children and good in adults. These data suggest that in children, fear and disgust vocalizations may both promote attention to stimuli that adults find disgusting and/or fear-provoking, suggesting that “preparedness” may not be wholly emotion-specific.  相似文献

Should a history of child abuse be taken into consideration when a juvenile offender is punished? Although some research shows that child abuse is used as a mitigating factor for juvenile offenders (i.e., elicits less punitive sentences), surveys of juvenile court officials reveal that it is considered an aggravating factor. Specifically, in controlled mock jury studies in which child abuse is experimentally manipulated, child abuse elicits less punitive sentences. In contrast, child abuse elicits more punitive sentences in a nonexperimentally controlled environment—the juvenile justice system. This article provides a comprehensive literature review to explain these conflicting bodies of research by considering factors that naturally covary with childhood abuse: chaotic family environment, mental health problems, behavioral problems, and school problems.  相似文献

This study investigates the outcome of an intervention program to establish oral feeding after prolonged tube feeding in children. The intervention is based on supervised reduction of enteral formula within a few days supported by a 3‐week program of speech therapy, occupational therapy, psychoanalytically based eating therapy, physical therapy, psychodynamic coaching, and nutritional counseling of the infant and his or her parents. Two hundred twenty‐one cases were included in this study. All patients had been severely ill or were handicapped and had been exclusively fed by tube for most of their lives. The major outcome variable was complete discontinuation of tube feeding with sufficient oral feeding after treatment, defined as the child's ability to sustain stable body weight by self‐motivated oral feeding. Two hundred three patients (92%) were completely fed orally after treatment. Tube feeding was discontinued completely within 8 days in mean, and mean in‐patient treatment time was 21.6 days. The current method can be used by a trained and experienced team to wean tube‐dependent children from prolonged tube feeding. Tube weaning should be addressed from the beginning of tube feeding in all children who are expected to restore oral feeding after the phase of nutritional stabilization. Since successful programs are rare, we were motivated to present our results of this elaborate program in this article.  相似文献

It has long been suspected that attentional processes differ between olfaction and the other senses. Here, we test whether voluntary dishabituation, seen, for example, when we re‐attend to the ticking of a clock, can occur in olfaction. Participants were seated in an odorized room, where at various intervals they had to evaluate what they could smell. An experimental group had one nostril open and the other closed, except during the evaluations, so that the closed side was subject to centrally driven habituation, but not peripheral adaptation. A control group had both nostrils closed except during evaluations. Following exposure, the experimental group could not report the room's odor in either the centrally habituated nostril (i.e., that remained closed) or the nostril that remained open, while the control group could. This effect could result from a number of causes, including olfaction's unique neuroanatomy, functional constraints imposed by detecting volatile chemicals, and as a consequence of limited cortical resources, with implications for the functional value of consciousness.  相似文献

Object recognition is a crucial component of both visual and auditory perception. It is also critical for olfaction. Most odours are composed of 10s or 100s of volatile components, yet they are perceived as unitary perceptual events against a continually shifting olfactory background (i.e. figure-ground segregation). We argue here that this occurs by rapid central adaptation to background odours combined with a pattern-matching system to recognise discrete sets of spatial and temporal olfactory features-an odour object. We present supporting neuropsychological, learning, and developmental evidence and then describe the neural circuitry which underpins this. The vagaries of an object-recognition approach are then discussed, with emphasis on the putative importance of memory, multimodal representations, and top-down processing.  相似文献
