This review provides a new integration of recent research that has formed the basis of a social identity explanation of supportive collective behaviour among survivors in emergencies and disasters. I describe a model in which a sense of common fate is the source of an emergent shared social identity among survivors, which in turn provides the motivation to give social support to others affected. In addition, by drawing on the concept of relational transformation in psychological crowds, I show how an emergent shared social identity can engender a range of further behavioural and cognitive consequences that contribute to collective self-organisation in emergencies, including expected support, coordination of behaviour, and collective efficacy. It will be argued that the model can been applied to explaining how potentially dangerous crowd events avoid disaster: shared social identity operates as the basis of spontaneous self-organisation in these cases, as in many emergencies and disasters.  相似文献

Relatively few experiments have measured the time course of free recall from episodic or semantic memory. Of those that have, most report that cumulative recall is a negatively accelerated exponential (or hyperbolic) function that is characterized by two properties: asymptotic recall and rate of approach to asymptote. The most common measure of free recall performance (viz., the number of items recalled) provides a reasonably good estimate of asymptotic recall if a relatively long recall period is used (which is rare), but the effect of experimental manipulations on the rate of approach to asymptote cannot be determined without timing when recall responses occur. The research reviewed herein suggests that the rate of approach to asymptote may offer an estimate of the breadth of search through long-term memory. The search in question, unlike most of those investigated in the memory literature, is unique in that it requires minutes rather than milliseconds to complete.  相似文献

This paper reviews the advice-giving and advice-taking literature. First, the central findings from this literature are catalogued. Topics include: advice utilization, confidence, decision accuracy, and differences between advisors and decision-makers. Next, the implications of several variations of the experimental design are discussed. These variations include: the presence/absence of a pre-advice decision, the number of advisors, the amount of interaction between the decision-maker and the advisor(s) and also among advisors themselves, whether the decision-maker can choose if and when to access advice, and the type of decision-task. Several ways of measuring advice utilization are subsequently contrasted, and the conventional operationalization of “advice” itself is questioned. Finally, ways in which the advice literature can inform selected topics in the organizational sciences are discussed.  相似文献

Neuropsychological studies of aggressive psychopaths have revealed characteristic deficits in skills that require verbal mediation, conceptual integration, and the abilities to anticipate consequences of actions and to use feedback from behavior to modify maladaptive response patterns. Formulations of this impairment pattern in terms of frontal lobe and left hemisphere dysfunction are reviewed. It is proposed that the aggressive psychopath suffers from an inability to form a self-referential conceptual classification system for behavioral control and that this predisposes to behavioral disinhibition in situations of stress and interpersonal ambiguity. Finally, implications of neuropsychological studies of aggressive psychopathy for the study of personality and psychopathology are discussed.  相似文献

The present article reviews modern research on the psychology of emotion regulation. Emotion regulation determines the offset of emotional responding and is thus distinct from emotional sensitivity, which determines the onset of emotional responding. Among the most viable categories for classifying emotion-regulation strategies are the targets and functions of emotion regulation. The emotion-generating systems that are targeted in emotion regulation include attention, knowledge, and bodily responses. The functions of emotion regulation include satisfying hedonic needs, supporting specific goal pursuits, and facilitating the global personality system. Emotion-regulation strategies are classified in terms of their targets and functions and relevant empirical work is reviewed. Throughout this review, emotion regulation emerges as one of the most far-ranging and influential processes at the interface of cognition and emotion.  相似文献

Based on an integrative review of the relevant literature in and on person-centred and experiential (PCE) therapy, this study identifies and discusses the findings of 13 articles on the delivery of individual video counselling and psychotherapy. Six overarching themes were identified: the discrepancy of the experiences of clients and practitioners; the possibility of good-quality PCE therapy (psychotherapy and/or counselling); “doing” PCE therapy online; “being” online; the role of technology; and implications for training and practice. It is suggested that all these have implications for ongoing practice and education/training, and need to be considered by practitioners, educators/trainers, and professional bodies.  相似文献

In this research, we examine how young children perform induction in the domain of biology. According to the essentialist view, even young children have a priori knowledge that some predictors of biological properties are central, whereas others are peripheral. According to the flexible-learning view, the roles of predictors are not fixed, and young children flexibly learn the predictive value of each predictor. In the experiment reported, 4- to 5-year-olds and 11- to 12-year-old preadolescents were taught the predictive values of features that were (by the essentialist account) either central or peripheral for predicting the biological properties of animals. Retention of the learned predictors was then tested immediately after learning, 1 h after leaning, and 2.5–3.5 months later. The results indicate that 2.5–3.5 months after learning, young children retained learned predictors well regardless of their putative centrality, whereas preadolescents were likely to retain and recall only central, but not peripheral, predictors.  相似文献

Semantic ambiguity often occurs within a language (e.g., the word “organ” in English means both a body part and a musical instrument), but it can also cross a language boundary, such that a given word form is shared in two languages, but its meanings are different (e.g., the word “angel” means “sting” in Dutch). Bilingual individuals are therefore faced not only with ambiguity in each of their languages, but also with ambiguity across languages. The current review focuses on studies that explored such cross-language ambiguity and examines how the results from these studies can be integrated with what we have learned about within-language ambiguity resolution. In particular, this review examines how interactions of frequency and context manifest themselves in ambiguity that crosses a language boundary and call for the inclusion of language context as a contributing factor. An extension of the monolingual reordered access model (Duffy, Morris, & Rayner, 1988 Duffy, S. A., Morris, R. K. and Rayner, K. 1988. Lexical ambiguity and fixation times in reading. Journal of Memory and Language, 27: 429446. [Crossref], [Web of Science ®] [Google Scholar]) is outlined to discuss the interactions between these factors. Furthermore, the effects of the similarity between the two meanings, task differences, and individual differences are explored. This review highlights the need for studies that test within- and cross-language ambiguity in the same individuals before strong conclusions can be made about the nature of interactions between frequency, semantic context, and language context.  相似文献

Learning about the structure of the world requires learning probabilistic relationships: rules in which cues do not predict outcomes with certainty. However, in some cases, the ability to track probabilistic relationships is a handicap, leading adults to perform non‐normatively in prediction tasks. For example, in the dilution effect, predictions made from the combination of two cues of different strengths are less accurate than those made from the stronger cue alone. Here we show that dilution is an adult problem; 11‐month‐old infants combine strong and weak predictors normatively. These results extend and add support for the less is more hypothesis: limited cognitive resources can lead children to represent probabilistic information differently from adults, and this difference in representation can have important downstream consequences for prediction.  相似文献

The author reviews the definitions, epidemiology, evolving research, offender, and offense characteristics of sexual homicide, a form of intentional killing that occurs in less than 1% of homicides in the United States. Although the extant research is limited by very few comparative studies, repetitive use of small, nonrandom samples, retrospective data, no prospective studies, and the absence of any predictive statistical analyses, the yield over the past 100 years is impressive. The author advances a clinical typology of sexual murderers. The first group of compulsive sexual murderers leaves behind organized crime scenes and are usually diagnosed with sexual sadism and antisocial/narcissistic personality disorders. They are chronically emotionally detached, often primary psychopaths, are autonomically hyporeactive, and the majority experience no early trauma. The second group of catathymic sexual murderers leave behind disorganized crime scenes and are usually diagnosed with a mood disorder and various personality disorders that may include schizoid and avoidant traits. They are hungry for attachment, only moderately psychopathic, are autonomically hyperreactive, and have a history of physical and/or sexual trauma.  相似文献

Moral injury was originally conceived as a socially-inflicted wound of betrayal experienced by military veterans (Shay, 1994). However, moral injury has since been redefined by psychological researchers as an individualised, predominantly perpetration-driven, and psychopathological phenomenon (e.g., Currier et al., 2015; Jinkerson, 2016). However, social scientific researchers (e.g., Hodgson & Carey, 2017; Molendijk, 2019; Wiinikka-Lydon, 2017) have contested mainstream psychology's medicalisation and decontextualisation of moral injury. This theoretical review integrates insights from across these discourses, and brings them into dialogue with ideas from moral psychology, evolutionary science, and community psychology. The aim of this cross-disciplinary review is to promote a more holistic understanding of moral injury that does justice to its individual and social dimensions. Drawing on these different theoretical strands, this paper proposes that moral injury can be best understood as a psychological wound to basic human needs for social belonging and cohesion. The implications of this integrative understanding of moral injury for applied psychologists and other societal actors are explored. While the relevance of moral injury to civilian populations such as health and social care professionals is clear (e.g., Dombo et al., 2013; French et al., 2021), this paper focuses on military veterans, whose experiences originally prompted the coinage of the term.

Accumulated recent research suggests that prior knowledge of multiple languages leads to advantages in learning additional languages. In the current article, we review studies examining potential differences between monolingual and multilingual speakers in novel language learning in an effort to uncover the cognitive mechanisms that underlie such differences. We examine the multilingual advantage in children and adults, across a wide array of languages and learner populations. The majority of this literature focused on vocabulary learning, but studies that address phonology, grammar, and literacy learning are also discussed to provide a comprehensive picture of the way in which multilingualism affects novel language learning. Our synthesis indicates two avenues to the multilingual advantage including direct transfer of prior knowledge and prior skills as well as indirect influences that result from multilingual background and include more general changes to the cognitive-linguistic system. Finally, we highlight topics that are in need of future systematic research.  相似文献

We conceptualize, develop, and test a multiple-item bundle valuation model through which decision makers are able to make inferences about the value of uncertain items based on the value of certain items. Results of four experiments indicate that bundling a low-value certain item with a high-value uncertain item, which are not substitutes, results in a bundle valuation lower than the value of the uncertain item alone. We refer to this highly unexpected and previously unexplained phenomenon as “hyper-subadditivity.” In addition we find that bundling a high-value certain item with a low-value uncertain item leads to superadditivity, even though the items are not complements. Hence, we find that when two objects are bundled together, and one has a more certain value, decision makers use the value of the certain item to infer the value of the less certain item. They might infer that the other (less certain) object must be worth an amount similar to the item with which they are paired. We further demonstrate that reducing uncertainty eliminates these effects, and that direct value inferencing (not simple numeric priming, nor inferences about quality) is the most likely mechanism driving these effects.  相似文献

In this paper we will review recent neuroimaging research in schizophrenia, with an aim to critically evaluate several recent proposals concerning the nature and the timing of the neuroanatomic abnormalities underlying the disorder. Specifically, enlargement of cerebrospinal fluid spaces, deficits in cortical gray matter, and reduced volume of mesiotemporal structures have all been reported in patients in the first episode of schizophrenia, their first-degree relatives, and individuals with schizotypal personality disorder, supporting the possibility that these abnormalities reflect a genetically mediated neurodevelopmental disorder. These findings from the empirical literature will be synthesized from the perspective of dual cytoarchitectonic trends theory of neurodevelopment, as well as in relation to current conceptions of the schizophrenia prodrome. We believe that the evidence shows that sufficient groundwork has been laid to begin longitudinal neuroimaging studies of adolescents at clinical risk for schizophrenia, in order to more definitively determine the pathophysiology of the disorder. Such information could have significant implications in terms of understanding the prediction, treatment, and ultimately the prevention of schizophrenia.  相似文献

The aim of this article is to reinterpret the results obtained from the research analyzing the role played by spatial frequencies in face perception. Two main working lines have been explored in this body of research: the critical bandwidth of spatial frequencies that allows face recognition to take place (the masking approach), and the role played by different spatial frequencies while the visual percept is being developed (the microgenetic approach). However, results obtained to date are not satisfactory in that no single explanation accounts for all the data obtained from each of the approaches. We propose that the main factor for understanding the role of spatial frequencies in face perception depends on the interaction between the demands of the task and the information in the image (the diagnostic recognition approach). Using this new framework, we review the most significant research carried out since the early 1970s to provide a reinterpretation of the data obtained.  相似文献

ObjectivesThis review provides an integrative argument for the use of observation as an intervention to manipulate individual collective efficacy beliefs in sports teams.DesignAn exploration of the conceptual and empirical evidence underpinning observation-based interventions for increasing collective efficacy.MethodA presentation of reflections on the following. First, we reflect on existing techniques used to increase self- and collective efficacy beliefs. Second, we consider collective efficacy in the context of observational learning and the various modeling techniques employed in the sports and motor performance literature. Third, we highlight relevant literature from neuroscience, outlining the analogous neural pathways evident for social cognition (i.e., collective efficacy) and observation.ResultsThis review presents a case for the use of observation interventions to manipulate collective efficacy, drawing upon social psychological frameworks of human behavior, the observation-based literature, and contemporary understanding of brain and behavior.ConclusionsObservation-based interventions are suited for collective efficacy manipulation in sport. There is a need to advance understanding of this relationship in order to maximize improvements in collective efficacy across group contexts.  相似文献

Being imitated, conformity, and social influence: An integrative review   总被引:1,自引:0,他引:1  
The recently developed literature on the effects of being imitated and the social influence function of imitation are reviewed, as is related literature on conformity from social psychology. Then, this research is considered within a number of theoretical contexts, but especially within the conceptual framework of Byrne's elaboration of effectance motivation. Finally, questions are raised which need to be addressed in future research.  相似文献

Facial expressions of emotion involve a physical component of morphological changes in a face and an affective component conveying information about the expresser’s internal feelings. It remains unresolved how much recognition and discrimination of expressions rely on the perception of morphological patterns or the processing of affective content. This review of research on the role of visual and emotional factors in expression recognition reached three major conclusions. First, behavioral, neurophysiological, and computational measures indicate that basic expressions are reliably recognized and discriminated from one another, albeit the effect may be inflated by the use of prototypical expression stimuli and forced-choice responses. Second, affective content along the dimensions of valence and arousal is extracted early from facial expressions, although this coarse affective representation contributes minimally to categorical recognition of specific expressions. Third, the physical configuration and visual saliency of facial features contribute significantly to expression recognition, with “emotionless” computational models being able to reproduce some of the basic phenomena demonstrated in human observers. We conclude that facial expression recognition, as it has been investigated in conventional laboratory tasks, depends to a greater extent on perceptual than affective information and mechanisms.  相似文献
