A recent model of collective action distinguishes 2 distinct pathways: an emotional pathway whereby anger in response to injustice motivates action and an efficacy pathway where the belief that issues can be solved collectively increases the likelihood that group members take action (van Zomeren, Spears, Fischer, & Leach, 2004). Research supporting this model has, however, focused entirely on relatively normative actions such as participating in demonstrations. We argue that the relations between emotions, efficacy, and action differ for more extreme, nonnormative actions and propose (a) that nonnormative actions are often driven by a sense of low efficacy and (b) that contempt, which, unlike anger, entails psychological distancing and a lack of reconciliatory intentions, predicts nonnormative action. These ideas were tested in 3 survey studies examining student protests against tuition fees in Germany (N = 332), Indian Muslims' action support in relation to ingroup disadvantage (N = 156), and British Muslims' responses to British foreign policy (N = 466). Results were generally supportive of predictions and indicated that (a) anger was strongly related to normative action but overall unrelated or less strongly related to nonnormative action, (b) contempt was either unrelated or negatively related to normative action but significantly positively predicted nonnormative action, and (c) efficacy was positively related to normative action and negatively related to nonnormative action. The implications of these findings for understanding and dealing with extreme intergroup phenomena such as terrorism are discussed.  相似文献

The current study builds on links between academic social identification and learning behaviours and extends these models by also considering the level of compatibility between the student identity and the pre‐existing self‐concept. This is a crucial extension, in the context of broadening access to higher education and fostering belonging and learning in nontraditional students. Further, where previous work focused on learning behaviours that enhance performance (often learning approaches), we also consider performance‐undermining behaviours (self‐handicapping and procrastination). These effects are explored in survey responses from an undergraduate student sample (N = 121) from UK and broader European samples. Participants were predominantly female (69%) and native English speakers (87%). Three models of the relationships between these variables were tested using Mplus. Results indicate that performance‐undermining behaviours are predicted by identity incompatibility, but not identification level; deep learning approaches are predicted by identification level, but not identity incompatibility. This provides first evidence that identity incompatibility is not just a moderator of the identification‐learning relationships but, in fact, a separate identity process for consideration. We also present initial evidence for a mediation model, where in the identity variables are related to procrastination and self‐handicapping via learning approaches.  相似文献

Ecological Momentary Assessment Research in Behavioral medicine   总被引:4,自引:0,他引:4  
Behavioral medicine research often seeks to examine relatively complex theoretical models and clinical processes. Traditional designs, based on retrospective self-report in the natural environment or laboratory-based studies, cannot assess complex and temporally dynamic psychological, behavioral, and physiological processes in the natural environment. An alternate research approach, Ecological Momentary Assessment (EMA), provides a method to collect such data. This research approach and these data allow investigation of a number of research questions not amenable to other data collection methods. Examples of research questions uniquely suited for EMA data include, but are not limited to: (1) the comparison of retrospective data to momentary data; (2) evaluation of physiological and psychosocial processes in the natural environment; (3) the relation of symptoms and other disease processes to characteristics of the natural environment; and (4) examination of dynamic changes in psychosocial variables that may mediate improvement following treatment. Despite the strengths of EMA data, a number of challenges exist – including logistic, analytic, and interpretation problems – to the easy implementation of EMA approaches in behavioral medicine.  相似文献

It has been suggested that maintenance in visuospatial immediate memory involves implicit motor processes that are analogous to the articulatory loop in verbal memory. An alternative account, which is explored here, is that maintenance is based on shifts of spatial attention. In four experiments, subjects recalled spatial memory span items after an interval, and in a fifth experiment, digit span was recalled after an interval. The tasks carried out during the interval included touching visual targets, repeating heard words, listening to tones from spatially sepa-rated locations, pointing to these tones, pointing to visual targets, and categorizing spatial tar-gets as being from the left or right. Spatial span recall was impaired if subjects saw visual tar-gets or heard tones, and this impairment was increased if either a motor response or a categorical response was made. Repeating words heard in different spatial locations did not impair recall, but reading visually presented words did interfere. For digit span only, the tasks involving a verbal response impaired recall. The results are interpreted within a framework in which active spatial attention is involved in maintaining spatial items in order in memory, and is interfered with by any task (visual, auditory, perceptual, motor) that also makes demands on spatial attention.  相似文献

The Thematic Apperception Test (TAT) was administered to followers of Bhagwan Shree Rajneesh in their commune in central Oregon. The Rajneeshee subjects had been high achievers (with advanced degrees and/or previous incomes greater than 30,000 dollars in 1984 dollars). Later, TATs were administered to persons matched for gender, age, education, and occupation but not involved in new religions. The final matched sample included 24 men and 20 women, half of whom were Rajneeshees. TATs were coded for a variety of formal variables as well as personality ratings. Though the analysis showed no between-group differences on most variables, significant mean differences occurred on ratings of unusual conditions, quest, and narcissism, with Rajneeshees higher than comparison subjects. Gender differences in personality variables were not conspicuous. Factor analysis established a strong productivity element. Card 16 (the blank card) provided the greatest number of differences.  相似文献

Articular proprioception is normally considered to provide accurate information about limb position, particularly in ball skills in which the eyes are be occupied with tracking the ball. If this is so, then preventing sight of the catching hand without interfering with visual tracking of the ball should affect the accuracy of catching. The experiment reported here indicates that is not the case. Catching is much less accurate if the hand cannot be seen. The errors made are in positioning of the catching hand, which frequently does not contact the ball. In addition, subjects showed larger changes in the felt length arms after catching without sight of the hand than did those who could hand while catching. Visual information about the position of the hand for catching, and this may be because the proprioceptive system is by vision.  相似文献

The current paper explores perceived norm conflict, social identification, and learning approaches in the applied context of higher education. Research has established the influence of identification with fellow students, and their perceived norms, on student approaches to learning. However, in the current paper, we argue that this model is not entirely ecologically valid and that students are not the only source of normative influence in the study context. In this first step to unpack these complex normative influences, we examine the next most‐proximal source of normative information—the educator. In essence, we explore the ways that the normative communications of a within‐field educator can also influence student learning approaches and the ways these two sets of normative effects may interact. Testing a sample of undergraduate students at Australian universities, we explore how students resolve conflicting intragroup norm sources. Findings suggest that, in line with previous literature, stronger identification with the field of study is associated with deep learning approaches, and this effect is moderated by perceived student norms such that the valence of the study norms can undermine or accentuate this effect. Novel results unpacking the effects of normative conflict suggest that this moderation effect is only present when educator norms are ambiguous and that, in instances of clearly conflicting normative messages, the identification main effect prevails. The implications and applications are discussed.  相似文献

Phonological encoding in the silent speech of persons who stutter   总被引:1,自引:0,他引:1  
The purpose of the present study was to investigate the role of phonological encoding in the silent speech of persons who stutter (PWS) and persons who do not stutter (PNS). Participants were 10 PWS (M=30.4 years, S.D.=7.8), matched in age, gender, and handedness with 11 PNS (M=30.1 years, S.D.=7.8). Each participant performed five tasks: a familiarization task, an overt picture naming task, a task of self-monitoring target phonemes during concurrent silent picture naming, a task of monitoring target pure tones in aurally presented tonal sequences, and a simple motor task requiring finger button clicks in response to an auditory tone. Results indicated that PWS were significantly slower in phoneme monitoring compared to PNS. No significant between-group differences were present for response speed during the auditory monitoring, picture naming or simple motor tasks, nor did the two groups differ for percent errors in any of the experimental tasks. The findings were interpreted to suggest a specific deficiency at the level of phonological monitoring, rather than a general monitoring, reaction time or auditory monitoring deficit in PWS. Educational objectives: As a result of this activity, the participant should: (1) identify and assess the literature on phonological encoding skills in PWS, (2) enumerate and evaluate some major psycholinguistic theories of stuttering, and (3) describe the mechanism by which defective phonological encoding can disrupt fluent speech production.  相似文献

Both subjective distress and cognitive interference have been proposed as mechanisms underlying the negative effects of stress on cognition. Studies of aging have shown that distress is associated with lower cognitive performance, but none have examined the effects of cognitive interference. One hundred eleven older adults (M-sub(age)=80) completed measures of working memory, processing speed, and episodic memory as well as self-report measures of subjective distress and cognitive interference. Cognitive interference was strongly associated with poorer performance on all 3 cognitive constructs, whereas distress was only modestly associated with lower working memory. The results suggest that cognitive process related to stress is an important predictor of cognitive function in advanced age.  相似文献

Short-term memory for form-position associations was assessed using an object relocation task. Participants attempted to remember the positions of either three or five Japanese Kanji characters, presented on a computer monitor. Following a short blank interval, participants were presented with 2 alternative Kanji, only 1 of which was present in the initial stimulus, and the set of locations occupied in the initial stimulus. They attempted to select the correct item and relocate it back to its original position. The proportion of correct item selections showed effects of both articulatory suppression and memory load. In contrast, the conditional probability of location given a correct item selection showed an effect of load but no effect of suppression. These results are consistent with the proposal that access to visual memory is aided by verbal recoding, but that there is no verbal contribution to memory for the association between form and position.  相似文献
