Environmental behaviors have been analyzed from different theoretical models. The theory of planned behavior emphasizes the attitudinal aspects associated with behavior, while the value–belief–norm model regarding the environment focuses on the importance of moral components when setting environmental behaviors in motion. The objective of this study was to analyze both models, comparing both their degree of fit and their predictive power regarding recycling behavior. To do so, we used a sample made up of 154 Spanish housewives. The results indicated that despite the fact that the theory of planned behavior is a general model for predicting and explaining behavior, it has a greater degree of fit and greater capacity to predict recycling behavior than the value–belief–norm model regarding the environment.  相似文献

Individual differences in child temperament are associated with individual differences in language development. The present study examined the relationship between temperament and language ability in 109 twenty-four- to 30-month-old children. Parents and day-care teachers completed two questionnaires: the Primo Vocabolario del Bambino (Caselli & Casadio, 1995) and the Questionari Italiani del Temperamento (Axia, 2002). Researchers administered the First Language Test (Axia, 1993) to assess productive and receptive language in each child. Replicating previous research (Usai, Garello, & Viterbori, 2009), day-care teachers identified three temperamental profiles: most of the children fit into the first profile, typical of the Italian population; another profile was made up of easily distractible and not very persistent children, with a poor capacity to modulate motor activity; and the third profile of children were inhibited in new situations. A relationship was found between temperament assessed by day-care teachers and different levels of linguistic competence. In particular, the groups of "inattentive" and "inhibited" children showed poorer lexical and morphological abilities and a more immature vocabulary, characterised by the presence of more primitive components of the lexical repertory compared to the group of "typical" children. Unlike the results from day-care teachers, temperament questionnaires completed by parents revealed a 4-cluster-solution. Also, for parents, the "typical" profile is characterised by the largest vocabulary (productive and receptive) and the most mature semantic production.  相似文献

This study presents the validity and reliability analysis of a questionnaire that assesses emotion work in the service sector. Emotion work is a term introduced by Hochschild (1983) and it refers to the expression of organizationally desirable emotions to influence the interactions with clients at work. The results show a 6-factor structure: Requirement to display Positive, Negative and Neutral Emotions, Sensitivity Requirements, Interaction Control and Emotional Dissonance. The analysis of the sub-scale scores reveals that the most frequently expressed emotions are positive, whereas negative emotions are expressed less frequently.  相似文献

In this longitudinal study, we examined the role of work characteristics (creative requirement, job control, coworker and supervisor support) and personal initiative for teachers' idea generation, idea promotion, and idea implementation. Eighty-nine teachers responded to two surveys with an interval of two weeks. Hierarchical regression analyses showed that creative requirement and job control predicted idea generation, whereas support from coworkers and the supervisor predicted idea promotion. Coworker and supervisor support, as well as teachers' personal initiative, predicted idea implementation.  相似文献

Previous studies in rodents showed that chronic stress induces structural and functional alterations in several brain regions, including shrinkage of the hippocampus and the prefrontal cortex, which are accompanied by cognitive and emotional disturbances. Reduced expression of the neural cell adhesion molecule (NCAM) following chronic stress has been proposed to be crucially involved in neuronal retraction and behavioral alterations. Since NCAM gene polymorphisms and altered expression of alternatively spliced NCAM isoforms have been associated with bipolar depression and schizophrenia in humans, we hypothesized that reduced expression of NCAM renders individuals more vulnerable to the deleterious effects of stress on behavior. Here, we specifically questioned whether mice in which the NCAM gene is inactivated in the forebrain by cre-recombinase under the control of the calcium-calmodulin-dependent kinase II promoter (conditional NCAM-deficient mice), display increased vulnerability to stress. We assessed the evolving of depressive-like behaviors and spatial learning and memory impairments following a subchronic stress protocol (2 weeks) that does not result in behavioral dysfunction, nor in altered NCAM expression, in wild-type mice. Indeed, while no behavioral alterations were detected in wild-type littermates after subchronic stress, conditional NCAM-deficient mice showed increased immobility in the tail suspension test and deficits in reversal spatial learning in the water maze. These findings indicate that diminished NCAM expression might be a critical vulnerability factor for the development of behavioral alterations by stress and further support a functional involvement of NCAM in stress-induced cognitive and emotional disturbances.  相似文献

This study analyses the relationships between patients' dispositional optimism and pessimism and the coping strategies they use. In addition, the coping strategies repercussions on adjustment to chronic pain were studied. Ninety-eight patients with heterogeneous chronic pain participated. The assessment tools were as follows: Life Orientation Test (LOT), the Vanderbilt Pain Management Inventory (VPMI), the McGill Pain Questionnaire (MPQ), Hospital Anxiety and Depression Scale (HADS), and the Impairment and Functioning Inventory for Chronic Pain Patients (IFI). The hypothetical model establishes positive relationships between optimism and the use of active coping strategies, whereas pessimism is related to the use of passive coping. Active coping is associated with low levels of pain, anxiety, depression and impairment and high levels of functioning. However, passive coping is related to high levels of pain, anxiety, depression and impairment and low levels of functioning. The hypothetical model was empirically tested using the LISREL 8.20 software package and the unweighted least squares method. The results support the hypotheses formulated regarding the relations among optimism, pessimism, coping and adjust of chronic pain patients. By analysing optimism among chronic pain patients, clinicians could make better predictions regarding coping and adjustment.  相似文献

The Theory of Planned Behavior (TPB) is one of the main theoretical models in the study of the different variables, which influence in the practise of physical activity. The aim in this study was to develop a questionnaire based on TPB in physical activity context providing evidence for the validity of the obtained measures. The instrumental project included three independent studies. The first study entailed the construction and qualitative assessment of the items. In the second study, the analysis of factorial structure was performed by means of exploratory measures, and it showed that the reliability of measures was adequate. The third study provided evidence on the dimensionality of the scale. The confirmatory factorial analysis guaranteed the stability of factorial structure proposed by the TPB and provided evidence for the internal validity of the inventory. Moreover, this study provided evidence of its external validity.  相似文献

The objective of this study is to see whether Immigrant (IM) and Spanish (National) students (SP) need different kinds of help from teachers due to differences in motivation, family expectancies and interests and classroom-motivational-climate perception. A sample of Secondary Students -242 Spanish and 243 Immigrants- completed questionnaires assessing goal orientations and expectancies, family attitudes towards academic work, perception of classroom motivational climate and of its effects, satisfaction, disruptive behavior and achievement. ANOVAs showed differences in many of the motivational variables assessed as well as in family attitudes. In most cases, Immigrant students scored lower than Spanish students in the relevant variables. Regression analyses showed that personal and family differences were related to student's satisfaction, achievement and disruptive behavior. Finally, multi-group analysis of classroom-motivational-climate (CMC) showed similarities and differences in the motivational value attributed by IM and SP to each specific teaching pattern that configure the CMC. IM lower self-esteem could explain these results, whose implications for teaching and research are discussed.  相似文献

ABSTRACT

Faces belonging to the same category as the perceiver are better recognised than faces from different categories when tested immediately. After a delay, the same-category benefit persists and response bias becomes more liberal for other-category but not same-category faces. These effects are typically attributed to better encoding of same-category than other-category faces. To determine whether bias effects after a delay persist when immediate accuracy differences are minimised, Hispanic and Caucasian participants were given more study time for other-category than same-category faces. Memory was tested immediately and after a two-day delay. Discrimination accuracy was higher for other-category than for same-category faces during both test sessions. Bias was equivalent immediately, but after the delay, bias was more conservative for same-category than for other-category faces, especially in Caucasian participants. These results suggest that post-encoding processes differentially influence face memories from different categories, which may have implications for evaluating face memory in everyday situations.  相似文献
