The present study examined profiles of exercise goal content and the associations with need satisfaction, motivation regulation and exercise behavior, combining variable-centered and person-centered analytical approaches. The participants were 1084 (279 men and 805 women) Swedish adults, aged between 18 and 78 years, that were all active members of an Internet-based exercise program. Latent profile analysis (LPA) and structural equation modeling (SEM) were used to analyze the data. In SEM analysis intrinsic goals were related to need satisfaction and autonomous motivation, whereas extrinsic goals were most strongly associated with controlled motivation. LPA revealed five unique latent classes of goal content. These five classes differed in need satisfaction, motivation regulation and exercise behavior, with classes being characterized by more intrinsic goal profiles reporting higher need satisfaction and autonomous motivation. The results are discussed from a self-determination theory perspective and the benefits of using both variable and person-centered analytical approaches are highlighted.  相似文献

The main goal of the paper is to sketch an ontological model of visual content at the low- and medium-level of visual processing, relying on psychological conceptions of vision. It is argued that influential cognitive models contain assumptions concerning “objects of content,” that is, objects whose presence is a necessary condition of the adequacy of visual representations. Subsequently, the structure of considered objects of content is presented, and its development through the perceptual process is described. In addition, during the course of the article I present some connections between analytic metaphysics and the ontology of visual content.  相似文献

The present research intends to shed light on the processes enabling political minorities to transition into normatively acceptable groups, by investigating how a previously marginalised far‐right movement (the French National Front) is progressively becoming mainstream. Drawing on the social representations approach, we argue that perceived social norms play a pivotal role in this process. Using a longitudinal and experimental design, the study (N = 233) was implemented in the ecological context of the 2012 French presidential election at a Parisian university campus, a traditional anti‐far‐right bastion. We tested whether the electoral campaign altered the perceptions of social norms, whether the perceived social norms were easily malleable in this specific context and, most important, whether they influenced people's willingness to speak out in public against the far‐right movement. The findings support affirmative answers to all three questions. We conclude that, in periods of collective uncertainty, changing perceptions of social norms might play an important role in the weakening of public opposition to far‐right movements. This, in turn, helps to explain the recent transition to mainstream recognition of a number of previously marginalised political movements in Europe and around the globe.  相似文献

Maternal mind-mindedness has been described both as a cognitive-behavioural trait and as a relational construct. This study assessed stability over time and consistency across relationships of maternal mind-mindedness in relation to preschool and primary school siblings and compared representational and interactional mind-mindedness. Mothers with two children between 2½ and 10 years were assessed twice, nine months apart (N = 32 at Time 1; N = 30 at Time 2). Representational mind-mindedness for a partner/friend was also assessed twice. Mothers’ representational mind-mindedness showed temporal stability but was inconsistent across relationships with two children and a partner/friend. Conversely, mothers’ interactional mind-mindedness was stable and highly consistent across relationships with two children. This supports the possibility that mothers’ interactional mind-mindedness is trait-like, while findings are equivocal for representational mind-mindedness. Representational mind-mindedness and interactional mind-mindedness were unrelated in this preliminary study, suggesting that these measures of maternal mind-mindedness were not equivalent for this age group.  相似文献

Abstract

Hepatitis B and C viruses are more prevalent among injecting drug users than HIV. This study explored drug users' illness representations of hepatitis B and C using repertory grid methodology. Initially, nine drug users were presented with six elements including hepatitis B and C, and HIV. Constructs were elicited via the sequential form variation of the method of triads. Elements were rated on elicited constructs using a five-point scale, and analyzed using “Flexigrid”. In a second quantitative research stage, 52 drug users were presented with six elements and supplied constructs. Results of the first stage indicated participants were able to generate constructs relating to Leventhal et al.'s (1980) features of illness representations. Most constructs, however, were causal in nature. Participants perceived hepatitis B, C and HIV similarly along the causal component. This similarity on the causal component was largely replicated in the second research stage. Participants, however, distinguished HIV from hepatitis B and C along serious, cure and timeline features. Participants did not distinguish hepatitis B from hepatitis C. The implications of these results for health promotion are discussed.  相似文献

This study demonstrates that associations between colour words and the colours they denote are not mandatory. Experiments 1–3 used a go/no-go task in which participants responded to one print colour and one word and withheld response from another print colour and another word. In Experiment 1, the content of the words denoted noncolour entities. In Experiment 2 the two words denoted two colours that were different from the target print colours. In Experiment 3, the words denoted the same colours as the target print colours but each response set included incompatible print colour and word (e.g., one response to the print colour blue and the word “green” and another response to the print colour green and the word “blue”). Participants performed equally well in all the experiments. Experiment 4a used Arabic digits and words denoting numbers, two formats that are known to have shared representations. Here, participants had difficulties separating their responses to the digits and words. These results suggest that representations of words are distinct from the content that they represent, supporting the existence of distinct verbal and colour modules.  相似文献

ABSTRACT

To investigate the relationship between visual acuity and cognitive function with aging, we compared low-vision and normally-sighted young and elderly individuals on a spatial working memory (WM) task. The task required subjects to memorise target locations on different matrices after perceiving them visually or haptically. The haptic modality was included as a control to look at the effect of aging on memory without the confounding effect of visual deficit. Overall, age and visual status did not interact to affect WM accuracy, suggesting that age does not exaggerate the effects of visual deprivation. Young participants performed better than the elderly only when the task required more operational processes (i.e., integration of information). Sighted participants outperformed the visually impaired regardless of testing modality suggesting that the effect of the visual deficit is not confined to only the most peripheral levels of information processing. These findings suggest that vision, being the primary sensory modality, tends to shape the general supramodal mechanisms of memory.  相似文献

Goals can be defined as cognitive- and as value-related motivational constructs. Consequently, both goal elaboration and personal valuing of goals are emphasized as critical determinants of motivated action. From this perspective, it is argued that goals play an influential role in students' cognitions, and in their social and emotional processes. I explore students' strategies for dealing with potentially stressful classroom circumstances in relation to their goals by examining students' reactions to imagined specific academic stressors, focusing on their emotions, behavior, and goals. Four distinct strategies were defined: strategic flexible action, strategic rigid action, passive behavior, and disorganized behavior. It is suggested that (a) goals play a major role in articulating and integrating behaviors and emotions within a whole strategy, (b) particular combinations of goal characteristics - goal-setting, personal goal valuing, and goal difficulty - are required for successful coping, and (c) both productive behavior and emotional regulation are predicted by specific goal characteristics.  相似文献

The changing profile of drug use has highlighted the need for age-appropriate education which requires insight into children's representations of drugs. Representations were elicited from 134 children aged between 5 and 11 years, drawn from two schools, by asking them to draw and write their responses to questions relating to a story about losing and finding a bag of drugs. Relevant responses were generated by 119 children aged between 8 and 11 years. A content analysis of these responses revealed differences with school and age. Older children were more likely to recognize that drugs can be good or bad depending on type, quantity taken and reason for use. The children had firm ideas about who takes drugs and their motivations and were knowledgeable about methods of use. They recognized that drugs can be dangerous, but had little understanding of how or why. The children's representations were characterized by fear and uncertainty and most wanted to know more. These findings are used to argue that there is a need for child-centred constructivist approaches to drug education which seek to demystify drugs and drug use and to orientate children to the realities of the world of drugs in the 1990s.  相似文献
