Typically, falls in older adults occur when 2 tasks are performed simultaneously, due to the increased motor demand required to maintain stability and attention to perform the other task. The authors' purpose was to investigate walking while grasping, transporting, and placing a dowel on a predetermined target while manipulating difficulty levels of the manual task. Faller and nonfaller older adults performed a walking block (manual tasks combined with gait) and a stationary block (upright stance combined with manual tasks). The manual task involved grasping, transporting, and placing the dowel over a target. The results showed that fallers underperformed when compared with nonfallers in the task of placing the dowel over the target. The main difference observed between the groups was found in the condition that required allocation of attention between tasks and greater accuracy in the final placement of the object. Fallers showed gait stability similar to the nonfallers, but fallers were less accurate than nonfallers in the object placement task, especially for the highest level of difficulty. Thus, fallers seem to use a stability-first strategy. Fallers had problems in executing the manual tasks, which suggests a more global change in motor behavior rather than specific changes to balance control.  相似文献

This article aimed to investigate the role of Decent Work as a predictor of different types of Work Motivation and to explore the possible role of Psychological Capital in mediating this relationship. The Decent Work Questionnaire, the Multidimensional Work Motivation Scale, and the Psychological Capital Questionnaire were administered to 3004 knowledge workers, in Portugal and Brazil. Results from Structural Equation Modeling analyses support the hypothesized model, showing the predictor role of Decent Work and complete and partial mediation effects of PsyCap in different relationships between DW and Work motivation variables. The results also support the idea that a decent work context predicts more autonomous work motivations again with the mediation of PsyCap. In sum, the results suggest that decent work plays an important role in promoting a positive approach to work, and that Psychological Capital is an important mediating variable in the promotion of autonomous Work motivation. Limitations and practical implications conclude the article.  相似文献

We tested how anticipated emotions interact with personal experience in risk behavior to improve predictions from TPB on behavioral intention (BI) and behavioral expectation (BE) for sex without condom (Study 1) and excessive drinking (Study 2). In the moderate-high experience group, anticipated emotional profiles (AEPs) improve TPB prediction from 28% to 45% in the case of BI and from 19% to 40% in that of BE in relation to sexual risk behavior (Study 1), and from 23% to 36% in the case of BI and from 17% to 31% in that of BE in relation to binge drinking (Study 2). However, in the low-experience group (Study 2) AEPs improve TPB predictions for BI (12% to 34%) but not for BE, showing that in less experienced people BI and BE are not equivalent: anticipated emotions have different relevance in their prediction. These results were replicated using a general negative anticipated emotion index (averaging emotional categories).  相似文献

In recent years there has been an increasing interest among researchers and practitioners to analyze what makes a firm attractive in the eyes of university students, and if individual differences such as personality traits have an impact on this general affect towards a particular organization. The main goal of the present research is to demonstrate that a recently conceptualized narrow trait of personality named dispositional resistance to change (RTC), that is, the inherent tendency of individuals to avoid and oppose changes (Oreg, 2003), can predict organizational attraction of university students to firms that are perceived as innovative or conservative. Three complementary studies were carried out using a total sample of 443 college students from Mexico. In addition to validating the hypotheses, our findings suggest that as the formation of the images of organizations in students' minds is done through social cognitions, simple stimuli such as physical artifacts, when used in an isolated manner, do not have a significant impact on organizational attraction.  相似文献

We investigated the prevalence of body image dissatisfaction (BID) and associated factors in Florianopolis, Brazil. BID was analyzed in a sample (N = 1720) of adults through the Figure Rating Scale. The independent variables were sociodemographic factors, health behaviors, and morbidities. A multinomial logistic regression analysis was used. More men (14.2%) than women (6.1%) presented BID by being lighter than ideal (LI). Conversely, more women (66.6%) than men (46.3%) showed BID by being heavier than ideal (HI). BID by being HI was higher among older women, those with high BMI and those with a partner. In men, lower BMI and the presence of common mental disorders were associated with BID due to being LI. Advanced ages, alcohol abuse, physical inactivity, and obesity were associated with BID due to being HI. We must consider different public health interventions for men and women to reduce BID in Brazilian adults.  相似文献

This paper presents empirical findings from a 10-year longitudinal study of the educational and occupational socialization of 445 participants who were about 7 years old when first tested, and about 17 years old at the fourth time of measurement. In addition to collecting psychological measurements from the participants, behavioral reports were collected from significant others, specifically parents and teachers. Findings demonstrated that the life/career evolution of the participants can be understood only when taking into account the dynamic interaction between the unique personal characteristics of individuality of each person and the psychosocial theatre within which the person’s development takes place. Using the life-span, life-space framework of Super, and the Developmental-Contextual model from Vondracek, different emerging early predictors with unique impact on the process of educational and occupational socialization were identified, especially with respect to the probability of dropping out of school. Results in terms of gender, parental influences, psychological characteristics, and social context are discussed with regard to their potential implications for psychological interventions in schools, families, and occupational settings, as well as with regard to personal counseling in what concerns the management of life circumstances and behavioral ecosystems.  相似文献

This study aimed to investigate characteristics of Brazilian mothers' beliefs system, in the dimensions of autonomy and interdependence. A group of 600 women, half from state capitals and half from small towns, participated in the study. They were individually interviewed with Scales of Allocentrism, Beliefs about Parental Practices and Socialization Goals. Paired and Independent samples t tests and Multivariate GLM were performed. The results indicate that although mothers from both contexts value autonomy, mothers inhabiting small towns considered the relational dimension as the most important; whereas mothers inhabiting capitals valued equally both dimensions, either in their beliefs about practices or in the socialization goals for their children. Mothers from small towns have a higher mean score for allocentrism than mothers living in capitals. Thus, place of residence proved to be a relevant variable in the modulation of maternal beliefs. Educational level was not a significant factor in the variables considered and with this group of mothers. The study results are discussed in terms of their contribution to the understanding of the complex relationship between dimensions of autonomy and interdependence in mothers' beliefs system.  相似文献

Four experiments investigate the differences between implicit and explicit sequence learning concerning their resilience to structural and superficial task changes. A superficial change that embedded the SRT task in the context of a selection task, while maintaining the sequence, did selectively hinder the expression of implicit learning. In contrast, a manipulation that maintained the task surface, but decreased the sequence validity, affected the expression of learning specifically when it was explicit. These results are discussed in the context of a dynamic framework (Cleeremans & Jiménez, 2002), which assumes that implicit knowledge is specially affected by contextual factors and that, as knowledge becomes explicit, it allows for the development of relevant metaknowledge that modulates the expression of explicit knowledge.  相似文献

The present study investigated the following issues: (1) the structure of Bryant's Empathy Index for children and adolescents in a Spanish sample of 408 boys and 424 girls (M age=14.4 yr.), and (2) sex differences, including effect sizes and internal consistency of the scale. A principal components factor analysis with oblimin rotation showed that 20 of the index's 22 items load on three robust factors, related to Feelings of Sadness, Understanding Feelings, and Tearful Reaction with regard to the emotions of others. The 3-factor structure obtained an adequate fit to the data in the confirmatory factor analysis. Coefficients alpha ranged between .72 and .78. The 3 factors accounted for 42% of variance. As expected, girls scored higher than boys. It was concluded that the Spanish version of Bryant's Empathy Index has an acceptable reliability and construct validity, making it useful for research.  相似文献

Interactive effects of two environmental stressors when simultaneous ly present, i.e., noise and crowding, were analyzed. Four experimental conditions with two intensities of stress for each stressor (high versus low) were created. The stressors were concurrently introduced in laboratory conditions and their effects analyzed using several methodological approaches. More intense and negative effects were expected when the two highest intensities of noise and crowding concurred. 40 people (20 men and 20 women) participated in a study with a 2 x 2 factorial design. Analysis showed an increase in the measures of hemodynamic, endocrine, and neuroendocrine values of participants after being exposed simultaneously to noise and crowding. Similarly, their performance on complex tasks decreased, and they reported a subjective increase in stress. Capacity to cope was indicated by a statistically significant lower mean on the Dimension of Stress scale, tolerance of frustration during the multiple stress condition.  相似文献
