The extent to which an irrelevant distractor is processed during selective attention depends critically on the level of perceptual load on the relevant task. Here we show that perceptual load also affects the tendency of graspable objects to afford associated actions. Participants carried out a letter-search task and identified a target letter with the right or left hand while ignoring a graspable object with a handle oriented on the left or the right side of the object. The target letter was presented either on its own (low perceptual load) or alongside five nontarget letters (high load). Responses were faster when the action afforded by the ignored object was compatible (vs. incompatible) with the current target response, but only when the perceptual load of the letter search task was low. This finding is the first to demonstrate the role of perceptual load in action affordances by ignored objects. 相似文献

Building up on the socially induced model of burnout and the job demands-resources model, we examine how burnout can transfer without direct contagion or close contact among employees. Based on the social information processing approach and the conservation of resources theory, we propose that perceived collective burnout emerges as an organizational-level construct (employees' shared perceptions about how burned out are their colleagues) and that it predicts individual burnout over and above indicators of demands and resources. Data were gathered during the first term and again during the last term of the academic year among 555 teachers from 100 schools. The core dimensions of burnout, exhaustion, and cynicism were measured at the individual and collective level. Random coefficient models were computed in a lagged effects design. Results showed that perceived collective burnout at Time 1 was a significant predictor of burnout at Time 2 after considering previous levels of burnout, demands (workload, teacher-student ratio, and absenteeism rates), and resources (quality of school facilities). These findings suggest that perceived collective burnout is an important characteristic of the work environment that can be a significant factor in the development of burnout. 相似文献

Familial aggregation and the effect of parenting styles on three dispositions toward ridicule and being laughed at were tested. Nearly 100 families (parents, their adult children, and their siblings) completed subjective questionnaires to assess the presence of gelotophobia (the fear of being laughed at), gelotophilia (the joy of being laughed at), and katagelasticism (the joy of laughing at others). A positive relationship between fear of being laughed at in children and their parents was found. Results for gelotophilia were similar but numerically lower; if split by gender of the adult child, correlations to the mother’s gelotophilia exceeded those of the father. Katagelasticism arose independently from the scores in the parents but was robustly related to greater katagelasticism in the children’s siblings. Gelotophobes remembered punishment (especially from the mother), lower warmth and higher control from their parents (this was also found in the parents’ recollections of their parenting style). The incidence of gelotophilia was unrelated to specific parenting styles, and katagelasticism exhibited only weak relations with punishment. The study suggests a specific pattern in the relation of the three dispositions within families and argues for a strong impact of parenting styles on gelotophobia but less so for gelotophilia and katagelasticism. 相似文献

There is a phenomenon contributing to the current pattern of alcohol consumption among youngsters in Spain known as "botellon". From research financed by the National Plan on Drugs (2004-2007), data of 6009 youngsters (14-25 years old) were collected from three Spanish cities. Only individuals who engage in intensive consumption of alcohol (n = 2807) have been included. The purpose of this work has been to identify the different types of consumers at risk through a cluster analysis and to establish a profile for each particular group. Four groups were differentiated by age, gender, alcohol consumption and years of consumption. It was observed that adolescent students and university students of the same sex consume similar quantities of alcohol, and justify their consumption alluding to personal factors, whereas university students refer to issues related to control of leisure. The consumption by males is the highest, and they are the most likely to seek drunkenness. They associate to a lesser degree their consumption with the possibility of developing an addictive process. In general, all youngsters consider that their consumption will have no negative consequences. These results indicate the need to come up with different alternatives, addressing the particularities of each group. 相似文献

The main objective of this study was to build a model, which includes personal and social factors, that helps to highlight factors that promote health-related quality of Life (HRQoL) in children and in adolescents. A sample of 3195 children and adolescents was acquired from 5th and 7th graders from all five Portuguese regions. In this study three independent latent variables were specified--Physical, Psychological and Social and two dependent latent variables were measured: Health behavior and Quality of Life. The integrative model was composed by different components: (1) health-related quality of life, integrated by 8 dimensions from KIDSCREEN-52; (2) health behavior, (3) variables related to physical health; (4) variables related to social health; (5) variables related to psychological health. As results were found strong correlation between psychological dimensions and self-esteem and other factors and a structural equation model was developed. The model presented a RMSEA index of .08. Similarly, adjustment levels for the CFI, NFI and IFI vary above or around .90, which suggests a good adjustment for the hypothesized model. The model presented significant qui-square. This study showed that in all the samples studied, the psychological variables were those that contributed at a superior level to HRQoL. 相似文献

During reading, saccadic eye movements are generated to shift words into the center of the visual field for lexical processing. Recently, Krügel and Engbert (Vision Research 50:1532?C1539, 2010) demonstrated that within-word fixation positions are largely shifted to the left after skipped words. However, explanations of the origin of this effect cannot be drawn from normal reading data alone. Here we show that the large effect of skipped words on the distribution of within-word fixation positions is primarily based on rather subtle differences in the low-level visual information acquired before saccades. Using arrangements of ??x?? letter strings, we reproduced the effect of skipped character strings in a highly controlled single-saccade task. Our results demonstrate that the effect of skipped words in reading is the signature of a general visuomotor phenomenon. Moreover, our findings extend beyond the scope of the widely accepted range-error model, which posits that within-word fixation positions in reading depend solely on the distances of target words. We expect that our results will provide critical boundary conditions for the development of visuomotor models of saccade planning during reading. 相似文献

The current study analyzes the psychometric properties of an innovative three-dimensional (3D) simulation program, entitled Mii-School (MS), designed for the early detection of drug use and bullying in Secondary School children. This computer program showed adequate reliability and construct validity. The factorial structure, as well as the explanatory weight of the different factors, is presented. In addition, the results of a parallel version in paper and pencil format are also presented and compared with those of the computerized version (i.e., MS). There was a statistically significant difference between the two formats in the total (i.e., combined) sore of risk. When drug use and bullying were separately analyzed, differences were found only with regard to drug use. The relevance of these results as well as the suitability of this type of 3D instrument for the early detection of risky behaviors in young people are discussed. 相似文献

Adult male Wistar rats were bilaterally implanted with indwelling cannulae in the caudal region of the posterior cingulate cortex. After recovery, animals were trained in a step-down inhibitory avoidance task (3.0-s, 0.4-mA foot shock) and received, right after training, a 0.5-microl infusion of vehicle (phosphate-buffered saline, pH 7.4), of the GABA(A) receptor agonist muscimol (0.1 or 0.5 microg), of the cAMP-dependent protein kinase (PKA) stimulant Sp-cAMPS (0.1 or 0.5 microg), or of the PKA inhibitor Rp-cAMPS (0.1 or 0.5 microg). Animals were tested twice, 1.5 h and, again, 24 h after training, in order to examine the effects of these agents on short- and long-term memory, respectively. Muscimol (0.5 but not 0.1 microg) hindered retention for both short- and long-term memory (p <.05). Rp-cAMPS (0.1 or 0.5 microg) hindered retention for short-term memory (p <.05). In addition, these animals showed lower, but not significantly lower, latencies than controls in the test session for long-term memory (p >.10). A trend toward an amnesic effect on long-term memory was also observed after Sp-cAMPS infusion at 0.1 microg (p <.10). These results show that strong stimulation of GABAergic synapses in the caudal region of the rat posterior cingulate cortex right after training impairs short- and long-term memory (the latter less dramatically). The same occurs by inhibiting PKA activity with regard to STM and possibly to LTM. 相似文献
