The thousands of deaths and disabilities due to workplace accidents and injuries each year emphasize the importance of safety research. Despite occupational safety research that has contributed to identifying antecedents of safety, little is known about why and how safety knowledge leads to safety behaviours and how personal and situational factors interact to promote occupational safety. Using a multilevel, multisource, and time-lagged research design, the present study investigates whether safety knowledge affects safety behaviours through safety attitudes and further tests whether supervisory safety attitudes can impact the strength of these relationships and play a role as moderators of the proposed mediated relationship. Data were collected from workers (= 177) and supervisors (= 42) in a construction company in the energy industry at two time points. Results indicate full support for the moderated mediation model, demonstrating that worker safety attitudes partially mediate the relationship between safety knowledge and safety behaviours. Moreover, when supervisors had positive attitudes towards safety, both the direct relationship between worker safety attitudes and safety behaviours and the indirect relationship between safety knowledge and safety behaviours were more positive compared to when supervisors had negative safety attitudes. Theoretical and practical implications for occupational safety are discussed.  相似文献

Children are exposed to a gender-specific environment on an everyday basis through media, books, school supplies and especially toys. Children’s movies and television programs were found to portray protagonists’ occupational and private roles in a very traditional, gender-stereotypical way. The present two studies aimed to investigate gender-specific preferences in childhood and early adolescence. Cross-sectional data (study 1) were compared to longitudinal one (study 2) as we specifically aimed to investigate changes in gender preferences over time. A person-oriented approach, namely Configural Frequency Analysis was applied, to categorically analyze the relationship and development of gender-stereotyped preferences throughout childhood and early adolescence. Consistent with former studies, study 1 showed that gender-stereotypical preferences increased by age, for boys to a higher extent than for girls. By the age of twelve, these preferences had decreased supporting the theory of Kohlberg that children’s gender-stereotypic preferences continuously grow until around six years of age to finally lower thereafter. Gender-specific preferences generally became much more flexible over time.  相似文献

This research examined whether induced joy influences fifth graders’ performance in literacy tasks. Children were asked to recall a joyful experience, used as a joy induction, before completing either a grammar (Study 1) or textual comprehension task (Study 2). The grammar task involved understanding at the surface level and retrieval of appropriate declarative and procedural knowledge, but limited elaboration unlike the textual comprehension task, which tackled inference generation. By differentiating tasks based on depth of processing required for completion we aimed at testing the validity of two concurrent hypotheses: that of a facilitating effect and that of a detrimental effect of induced joy. Compared to controls, joy induced children showed better performance on the grammar task – specifically children with lower language ability. No differences across groups emerged as a function of joy induction on the text comprehension task. Results are discussed with respect to emotion effects on cognition.  相似文献

The current study represents the first quantitative investigation of the psychological ramifications of euthanasia‐related work. Results indicate that perceived euthanasia‐related strain is prevalent among shelter employees and is associated with increased levels of general job stress, work‐to‐family conflict, somatic complaints, and substance use; and with lower levels of job satisfaction. Analyses provide evidence that euthanasia‐related work has a significant negative relation with employee well‐being independent of its relation with generalized job stress. Exploratory analyses also suggest that individual, work, and organizational differences may influence the level of perceived stress and appear to be associated with certain aspects of employee well‐being. The need for future research of this topic and its relevance to a wide range of applied psychologists is discussed.  相似文献

Both working and immediate memories were assessed every 4h by specific short-term memory tasks over sustained wakefulness in 12 patients with obstructive sleep apnea and hypopnea syndrome (OSAHS) and 10 healthy controls. Results indicated that OSAHS patients exhibited lower working memory performances than controls on both backward digit span and complex Sternberg tasks. Speed and accuracy on Sternberg tasks were affected by memory load in both groups. However, immediate memory was not impaired in OSAHS patients. Diurnal and nocturnal SaO(2) were correlated with speed and accuracy high-speed memory scanning performance on Sternberg tasks in patients. These results suggest specific working memory deficits associated with OSAHS over sustained wakefulness with a possible deficiency in the central executive responsible for the higher information processing, in addition to a potentially insufficient storage capacity. Among OSAHS patients, working memory ability involved in high-speed memory scanning may be impaired by chronic hypoxemia.  相似文献

Background

According to several studies the application of different media in inpatient psychotherapy and psychiatry has proven to be a useful and effective addition to conventional methods of intervention. This study is the first to catalogue the current spread of media in inpatient treatment as well as the evaluations of media-supported interventions by therapists and patients.

Sample and method

In a representative survey conducted in all psychiatric and psychosomatic clinics in North-Rhine/Westphalia (response: 40 psychologists/doctors and 289 patients from 39 clinics) media equipment, usage of media in different areas, evaluation of and satisfaction with the media usage were measured by a questionnaire which was constructed especially for this purpose.

Results

A widespread usage and acceptance of media could only be found in some areas. The study identified large differences in equipment standards and media usage depending on the type of media, the area of usage and the specific clinic.

Conclusion

Recommendations for the further development and optimization of media usage in inpatient psychotherapy are derived from the results of this study.  相似文献

High social anxiety is a risk factor for the incidence of social anxiety disorder (SAD). Early diagnosis and intervention may prevent more severe psychiatric courses. Self-help programs may be a convenient, accessible, and effective intervention. This study examined the efficacy of a newly developed self-help program for SAD in individuals with subthreshold social anxiety. A total of 24 highly socially anxious individuals were randomly assigned to a DVD-based self-help program or to a wait-list control group. The self-help program is based on the cognitive model according to Clark and Wells (1995; adapted to German by Stangier, Clark, & Ehlers, 2006) and comprises eight sessions. ANOVAs based on an intention-to-treat model were used for data analyses. The self-help program was well accepted; just one person withdrew during the intervention. There were significant Time × Group interactions on all primary outcome measures. For the intervention group moderate to high within-groups effect sizes up to Cohen's d = 1.05 were obtained. Between-groups effect sizes ranged from 0.24 to 0.65 in favor of the active intervention. The newly developed DVD-based self-help program seems to be a promising intervention for highly socially anxious individuals as it reduces social anxiety symptoms.  相似文献

Predicting the consequences of actions is fundamental for skilled motor behavior. We investigated whether motor prediction is influenced by the fact that some movements are easier to perform and stabilize than others. Twelve subjects performed a bimanual rhythmical task either symmetrically or asymmetrically (the latter being more difficult and less stable) while oscillating in each hand an object attached to an elastic cord. Motor prediction was monitored through the adequacy of anticipatory grip force adjustments with respect to the elastic resisting force. Results showed less adequate predictive control during asymmetrical movements (compared with symmetrical ones). Furthermore, switching between modes of coordination induced even larger alterations. An interesting finding was that grip force control did not always stabilize around the expected value after voluntary transition. We conclude that motor prediction is affected by the degree of coordination between the upper limbs and by phase transitions and is prone to carryover effects.  相似文献
