Abstract Differences in fat consumption and psychosocial factors between subjects in different trans-theoretical stages of change for fat reduction were studied. Data on fat consumption, self-rated fat intake, attitudes, social support and self-efficacy were collected among a sample of 507 adults. Analysis of variance with Scheffe's multiple-comparison test was used to study differences in these factors between stages of change. Attitudes and social support were most positive among subjects in preparation and action. Self-efficacy expectations were lowest among subjects in contemplation and preparation. Fat consumption was highest among precontemplators hut no substantial differences between other stages were found. It is concluded that subjects in different stages of change differ in psychosocial factors that are regarded as important determinants of behavioral change. Based on these differences it is recommended to develop stage-tailored nutrition education. A majority of subjects in maintenance consumed more fat than is recommended. Therefore, it is suggested that the usually applied staging algorithms might need adjustment for a valid application in nutrition research. 相似文献

Proactive Customer Service Performance: Relationships With Individual,Task, and Leadership Variables
Despite the increasing interest in specific forms of proactive employee behavior in domains such as career development and organizational change, little research has investigated proactive behavior in the realm of customer service. Based on a review of the literatures on proactive behavior, customer service, and job performance, this study investigated relationships between a relevant set of individual and situational predictor variables and proactive customer service performance (i.e., individual service employees' self-started, long-term-oriented, and persistent service behavior that goes beyond explicitly prescribed requirements). Field survey data from 186 supervisor-subordinate dyads working in a large financial services organization demonstrated that proactive service performance, as rated by supervisors, was factorially distinct from prescribed task performance. Multiple regression analysis revealed that proactive service performance was significantly and positively associated with employee ratings of trait personal initiative, affective organizational commitment, task complexity, and participative leadership. The task and leadership variables explained incremental variance in proactive service performance beyond the individual predictors. 相似文献

This study examined the relation between brain activation and cognitive development using event-related brain potentials (ERPs) and a longitudinal design. Five-year-old girls performed a visual recognition (‘oddball’) task and an experimental analogue of the Piagetian conservation of liquid quantity task at three experimental sessions, with one year between consecutive sessions. The data revealed age-related changes in neurocognitive mechanisms common to both tasks. In comparing children before and after a Piagetian transition on a traditional clinical conservation test the data revealed a major shift in performance and ERPs to the experimental analogue of the liquid quantity task. These findings are consistent with a previously performed cross-sectional study and provide strong support for the hypothesis that cognitive transition is related to new neurocognitive mechanisms emerging during childhood. Possible implications of these findings for child neuropsychology are discussed. 相似文献

Previous studies have shown that children and adolescents often tend toward risky decisions despite explicit knowledge about the potential negative consequences. This phenomenon has been suggested to be associated with the immaturity of brain areas involved in cognitive control functions. Particularly, “frontal lobe functions,” such as executive functions and reasoning, mature until young adulthood and are thought to be involved in age-related changes in decision making under explicit risk conditions. We investigated 112 participants, aged 8–19 years, with a frequently used task assessing decisions under risk, the Game of Dice Task (GDT). Additionally, we administered the Modified Card Sorting Test assessing executive functioning (categorization, cognitive flexibility, and strategy maintenance) as well as the Ravens Progressive Matrices assessing reasoning. The results showed that risk taking in the GDT decreased with increasing age and this effect was not moderated by reasoning but by executive functions: Particularly, young persons with weak executive functioning showed very risky decision making. Thus, the individual maturation of executive functions, associated with areas in the prefrontal cortex, seems to be an important factor in young peoples’ behavior in risky decision-making situations. 相似文献

It has been assumed that overweight individuals show weak inhibitory control capacity leading to a failure to resist external cues for palatable food and that this deficit underlies the recently reported empirical association between obesity and attention deficit/hyperactivity disorder (ADHD). In childhood and adolescence, empirical research on this issue is scarce. Here, the hypothesis is tested that high body weight is associated with weak inhibitory control performance and that this association is moderated by age. The sample included 177 overweight and obese children and adolescents (BMI: M = 29.2, SD = 4.33; BMI-SDS: M = 2.45, SD = 0.43) between 8 and 15 years. Inhibitory control was assessed by a Go/No-Go task and an Interference Task. A principal component analysis yielded two components: impulsivity (fast but invalid responses) and inattention (highly variable reaction times). While controlling for age, gender, and maternal education level, we found that more obese children/adolescents showed more inattention. As indicated by a significant interaction effect, exclusively at younger ages, high impulsivity was associated with high body weight. The results thus confirm a link between low inhibitory control capacity and high body weight and might point to a developmental period with heightened significance of impulsivity for weight gain. 相似文献

Escape from the Island: Grammaticality and (Reduced) Acceptability of wh-island Violations in Danish
Ken Ramshøj Christensen Johannes Kizach Anne Mette Nyvad 《Journal of psycholinguistic research》2013,42(1):51-70
In the syntax literature, it is commonly assumed that a constraint on linguistic competence blocks extraction of wh-expressions (e.g. what or which book) from embedded questions, referred to as wh-islands. Furthermore, it is assumed that there is an argument/adjunct asymmetry in extraction from wh-islands. We report results from two acceptability judgment experiments on long and short wh-movement and wh-extraction from wh-islands in Danish. The results revealed four main findings: (1) No adjunct/argument asymmetry in extraction from wh-islands. (2) Long adjunct wh-movement is less acceptable than long argument wh-movement, and this difference is attributable to matrix verb compatibility and factivity, not D-linking. (3) Long movement reduces acceptability, but is more acceptable than island violations. (4) Training effects reveal that island violations, though degraded, are grammatical in Danish. Since the standard assumptions cannot account for the range of results, we argue in favor of a processing account referring to locality (processing domains) and working memory. 相似文献

The lack of affective responsiveness to others’ mental states – one of the hallmarks of psychopathy – is thought to give rise to increased interpersonal aggression. Recent models of psychopathy highlight deficits in attachment security that may, in turn, impede the development of relating to others in terms of mental states (mentalization). Here, we aimed to assess whether mentalization linked to attachment relationships may serve as a moderator for the relationship between interpersonal aggression and psychopathic traits in an adolescent community sample. Data from 104 males and females with a mean age of 16.4 years were collected on mentalization capacities using the Reflective Functioning Scale on the Adult Attachment Interview (AAI). Psychopathic traits and aggressive behavior were measured via self-report. Deficits in mentalization were significantly associated with both psychopathic traits and proactive aggression. As predicted, mentalization played a moderating role, such that individuals with increased psychopathic tendencies did not display increased proactive aggression when they had higher mentalizing capacities. Effects of mentalization on reactive aggression were fully accounted for by its shared variance with proactive aggression. Psychopathic traits alone only partially explain aggression in adolescence. Mentalization may serve as a protective factor to prevent the emergence of proactive aggression in spite of psychopathic traits and may provide a crucial target for intervention. 相似文献

In this article, we present the evaluation of the psychometric properties of a new self-report measure of Weight- and Body-Related Shame and Guilt (WEB–SG). The main purpose of the study was to measure shame and guilt feelings separately in obese individuals and investigate differing behavioral and emotional correlates of these emotions. Altogether, 331 obese participants completed the WEB–SG and other established self-report measures. A subset of the participants completed a 6-month follow-up. The WEB–SG proved to be internally consistent and temporally stable over a 6-month period. Regarding the factorial structure, a two-factor conceptualization was supported. The construct validity of the WEB–SG subscales was evidenced by a substantial overlap of common variance with related measures. The subscales Shame and Guilt showed differential correlation patterns to other scales. The WEB–SG is a brief, psychometrically sound measure for assessing body shame and guilt concerning weight control in obese individuals. 相似文献

The authors examine the extent to which the development of Wilhelm Reich’s ideas that led from Freud’s understanding of libido through marxism to sex-economy, from character-analysis to vegeto-therapy, from the orgasm reflex to the cosmic life energy “orgone”, might possibly be supported by a logic other than the one that Reich understood as "scientific". In so doing the authors differentiate the latent content from its manifest version and argue that if one focuses on the manifest content of Reich’s ideas, it is obvious that Reich ideologically falls back on the position of the “true socialists”, that his orgone theory ultimately re-vitalised the “new, true religion” Feuerbach’s (Engels 1888, p. 34) and that even Reich’s fetishization of genital love as a natural binding agent of human society finds its counterpart in Feuerbach. However, if one adds the latent content of Reich’s considerations, the unfolding of Reich’s ideas also presents the increasing reification of the human subject in its natural disguise as it emerged – in the light of historical materialism – under the social circumstances within which Reich developed his ideas. The authors develop the thesis that Reich’s misunderstanding of social processes as natural laws was not by coincidence but was due to the natural veil those processes were deceptively encircled. For as long as people keep the inner structure of their society beyond their social consciousness, they do not know what they are doing, so that the results of their social activity take on the appearance of being brought about by practical constraints caused by natural laws. 相似文献
