The purposes of this study were to identify and categorize the discursive practices through which consumers negotiate a lifestyle‐related identity in online lifestyle consumption communities. The empirical case is a very active community of consumers who adhere to the low‐carb/high‐fat diet. The paper contributes to communal consumption literature by showing how a lifestyle identity and the community evolve together. Focusing on an online community with lifestyle focus differentiates this study from previous research because nutritional choices influence the consumers' everyday life in a comprehensive manner. By employing a netnographic analysis on discussion board messages, 11 discursive practices are identified. These practices are categorized according to confirming/challenging and self‐directed/community‐directed dimensions. The paper provides a typology of online community dynamics, emphasizing the importance of challenging practices for community development. It also has important implications for companies who wish to understand food lifestyles and develop online platforms for their customers. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

Previous cross-cultural research using false-belief tasks has explored whether children's theory of mind develops synchronously across cultures. Success on false-belief tasks is usually interpreted as an important indicator of children's mental state understanding, but inconsistent findings have led to questions regarding the interpretation of children's success and failure. Based on the assumptions of perceptual access reasoning (Hedger & Fabricius, 2011 Hedger, J. A., & Fabricius, W. V. (2011). True belief belies false belief: Recent findings of competence in infants and limitations in 5-year-olds, and implications for theory of mind development. Review of Philosophy and Psychology, 2, 429447.[Crossref] [Google Scholar]) and reflecting on inconsistencies in cross-cultural false-belief research, we argue for the advantages of the additional use of true-belief tasks, which can help to differentiate between different levels of children's reasoning. Consequently, a false-belief task and a true-belief task were derived from typical Samoan adult–child interactions. The performance of 40 Samoan children aged 5 to 7 years old was compared to the performance of 40 age-matched German children. While German children passed both tasks, Samoan children failed the false-belief task and did not reply above chance level in the true-belief task. According to our knowledge, this is the first study using both a false-belief task and true-belief task in a cross-cultural setting. Our results reveal additional patterns of reasoning that are neither in line with perceptual access reasoning nor with a representational understanding of false beliefs. The study is discussed in terms of a more general problem of experimental research in non-Western settings.  相似文献

The study investigated spatial navigation by means of electrodermal activity (EDA). Two groups of healthy subjects (group 1, age <38; group 2, age ≥38) were recorded during navigation through two 3-D virtual mazes differing in difficulty, that is, Maze Simple (MazeS) and Maze Complex (MazeC). Our results show (1) an effect of difficulty, that is, larger skin conductance responses (SCRs) and slower velocity profiles while navigating through MazeC as compared to MazeS. (2) An effect of age, that is, larger SCRs and faster velocity profiles in younger subjects (group 1) compared to older subjects (group 2). (3) An effect of maze region, that is, SCRs increased when subjects entered dead ends with group 1 (young group) decreasing in velocity, whereas group 2 (old group) increased in velocity. (4) And an error memory effect, that is, subjects who remembered an error at a given decision point (crossroads preceding dead ends in MazeC) from previous trials, and then if they did not repeat that error, elicited decreased SCRs as compared to subjects who did not remember and subsequently repeated an error. The latter aspect is the most impactful as it shows that EDA is able to reflect error detection and memory during spatial navigation. Our data designate EDA as suitable monitoring tool for identification and differentiation of the affective correlates underlying spatial navigation, which has recently attracted researchers’ attention due to its increased use in 3-D virtual environments.  相似文献

This study explores nonverbal behaviors in the form of gestures and touch during elite handball matches. Based on a coding scheme, 616 postshot periods following a goal, stemming from 18 matches, were analyzed. Results revealed that, on average, 2.77 nonverbal behaviors were displayed after scoring. Play-off matches resulted in a higher average of nonverbal behaviors than league matches. The more a team was leading by, the higher the overall number of nonverbal behaviors; meanwhile, the overall amount of nonverbal behaviors declined over the course of a match. The results pinpoint to the situation specificity of nonverbal behaviors during ongoing matches.  相似文献

Health-related quality of life (QoL) is an important and widely used outcome measure in cardiac populations. We examined the relationship between positive affect and health-related quality of life, controlling for traditional cardiovascular risk factors, clinical variables and negative affect. We further investigated the role of gender in this relationship given the well-known gender differences in cardiovascular health. We enrolled 746 patients with coronary heart disease (CHD) before they entered outpatient cardiac rehabilitation. All patients completed the Global Mood Scale and the SF-36 Health Survey. Positive affect was independently associated with mental (p < .001) and physical QoL (p < .001) after controlling for control variables. Gender moderated the relationship between positive affect and physical QoL (p = .009) but not mental QoL (p = .60). Positive affect was positively associated with physical QoL in men (p < .001) but not in women (p = .44). The health-related QoL of patients with CHD is associated with a person’s level of positive affect.  相似文献

In two experiments, we examined the relation between gaze control and recollective experience in the context of face recognition. In Experiment 1, participants studied a series of faces, while their eye movements were eliminated either during study or test, or both. Subsequently, they made remember/know judgements for each recognized test face. The preclusion of eye movements impaired explicit recollection without affecting familiarity-based recognition. In Experiment 2, participants examined unfamiliar faces under two study conditions (similarity vs. difference judgements), while their eye movements were registered. Similarity vs. difference judgements produced the opposite effects on remember/know responses, with no systematic effects on eye movements. However, face recollection was related to eye movements, so that remember responses were associated with more frequent refixations than know responses. These findings suggest that saccadic eye movements mediate the nature of recollective experience, and that explicit recollection reflects a greater consistency between study and test fixations than familiarity-based face recognition.  相似文献

Existing theories of multiple object tracking (MOT) offer different predictions concerning the role of higher level cognitive processes, individual differences, effortful attention and parallel processing in MOT. Pylyshyn's model (1989) argues for an automatic parallel processing mechanism separate from other cognition, whereas alternative models (e.g., Kahneman & Treisman, 1984 or spotlight models) are based on higher level cognition such as spatial short‐term memory and/or effortful attention switching. These predictions were examined in Experiment 1 where identical objects and in Experiment 2 where visually and semantically distinct objects were tracked. Both experiments demonstrated a substantial individual variation in the estimated tracking capacity. Tasks measuring visuospatial short‐term memory and attention switching proved to be significant predictors of MOT. In addition, tracking performance deteriorated as a function of tracking time and set size. Our results are in contrast to Pylyshyn's model. A mechanism with both parallel and serial processing and temporary spatial memory is outlined to accommodate the observed pattern of results.  相似文献

The study examined the role played by changes in employees' goal-related affects in decreasing burnout during a group intervention. 62 white-collar employees, suffering from severe burnout, were randomized into 10-month group intervention programmes consisting of 16 intensive 1-day sessions every second week. The participants appraised their work and interpersonal goals according to their positive and negative affects weekly for 54 weeks. During the pre- and postintervention and follow-up (6 months later) measurements, the participants filled out a burnout measurement. The results, analysed by multilevel modelling, showed that a decrease in the negative affects and an increase in the positive affects of work and interpersonal goals during the later part of the intervention was related to a decrease in burnout symptoms. The decrease in goal-related negative affects was associated with a decrease in burnout in the postintervention measurement, whereas the increase in goal-related positive affects was related to a decrease in follow-up burnout.  相似文献

Aim: This study aims to explore if and how values and attitudes from trainees of different psychotherapeutic schools vary during training. Another aim has been to evaluate the extent of their therapeutic self-confidence during training. Methods: In a cross-sectional study, 171 trainees in German institutes with different theoretical orientations (Psychoanalysis – PA, Psychodynamic Therapy – PT and Cognitive Behavioral Therapy – CBT) participated. Results are reported for two questionnaires: Therapeutic-Attitudes-Candidate-Version (ThAT-CV) and Work-Involvement-Scales (WIS). Results: Therapeutic attitudes showed significant differences between trainees with different theoretical orientations but no significant difference between different levels of training within the same school. Whereas the PA and CBT trainees endorsed contrasting attitude profiles, the PT group displayed less differentiated attitudes in between those contrasts. Most trainees experienced their psychotherapeutic practice as challenging, and Stressful Involvement in therapy sessions was lower with more years in training. Female trainees reported more Healing Involvement and felt more competent in general than their male colleagues. Self-reported competence was higher the more congruent the trainees’ attitudes with their school's theoretical orientation. Conclusions: The ThAT-CV discriminates significantly between trainees of different therapeutic schools. Our sample demonstrates high identification with attitudes belonging to their theoretical orientation. This may account for high ratings of self-reported therapeutic competence. Attitudes seem to be formed before training and change little thereafter. Less differentiated attitudes may explain PT-trainees’ higher levels of Stressful Involvement.  相似文献

Cooperative hunting is a cognitively challenging activity since individuals have to coordinate movements with a partner and at the same time react to the prey. Domestic dogs evolved from wolves, who engage in cooperative hunting regularly, but it is not clear whether dogs have kept their cooperative hunting skills. We presented pairs of dogs with a reward behind a fence with two openings in it. A sliding door operated by the experimenter could block one opening but not both simultaneously. The dogs needed to coordinate their actions, so that each was in front of a different opening, if one of them was to cross through and get food. All 24 dog pairs solved the problem. In study 1, we demonstrated that dogs understood how the apparatus worked. In study 2, we found that, although the performance of the pairs did not depend on the divisibility of the reward, pairs were quicker at coordinating their actions when both anticipated rewards. However, the dogs did not monitor one another, suggesting that their solutions were achieved by each individual attempting to maximize for itself.  相似文献
