A previous study by Pollatsek et al. ( 1993 ) claims that the perceptual span in reading is restricted to the fixated line, i.e. readers typically focus their visual attention on the line of text being read. The present study investigated whether readers make use of content structure signals (paragraph indentations and topic headings) present several lines away from the currently fixated line. We reasoned that as these signals are low-resolution visual objects (as opposed to letter and word identity), readers may attend to them even if they are located some distance away from the fixated line. Participants read a hierarchically organized multi-topic expository text containing structure signals in either a normal condition or a window condition, where the text disappeared above and below a vertical 3° gaze-contingent region. After reading, participants were asked to produce a written recall of the text. The results showed that the overall reading rate was not affected by the window. Nevertheless, the headings were reread more in the normal condition than in the window one. In addition, more topics were recalled in the normal than in the window condition. We interpret the results as indicating that the readers visually attend to useful text layout features while considering bigger units than single text lines. The perception of topic headings located away from the fixated line may favour long-range regressions towards them, which in turn may favour text comprehension. This claim is consistent with previous studies that showed that look-back fixations to headings are performed with an integrative intent.  相似文献

Two studies were designed to develop and obtain information about the psychometric properties of a shortened 54-item, Spanish version of Ryff's Scales of Psychological Well-being adapted to older people. In Study 1, 267 older people completed the scales, and data were submitted to a principal components analysis. Then, 22 items were selected and grouped into four components (Self-confidence, Orientation to present, Stress, and Social tension) to form the Simplified Ryff's Well-being Scales. In Study 2, the new scales were administered to 107 older people. While internal consistency estimates were similar to those generally obtained for the 54-item scale, results extracted from a confirmatory factor analysis did not support any factorial model. Although the simplified scales can distinguish between conceptually different approaches to well-being, further studies are needed to obtain estimates of reliability and validity.  相似文献

Building and extending on just world theory, this paper studies people's negative reactions to innocent victims of rape or sexual assault. Specifically, we focus on an as yet unexplored variable that may help to explain these reactions, namely whether the perpetrator of the crime was similar or dissimilar to people who observed what happened to the victim. Perpetrator similarity refers to whether the perpetrator belongs to the personal world of the observer or not, and in accordance with predictions derived from just world theory, findings of three studies reveal that especially men take more physical distance from an innocent victim (Study 1) and blame (Study 2) and derogate (Study 3) an innocent victim more when the perpetrator is similar to them as opposed to when the perpetrator is different from them. Implications are discussed. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

Although the importance of intrinsic motivation at work is already known, the relationship between organizational justice and employees’ motivation remains unexplored. Consequently, the purpose of the present study was to examine the predictive role of organizational justice on intrinsic motivation and the mediation effect of fundamental needs satisfaction in the study of organizational justice and employees’ intrinsic motivation. Key variables have been measured with a sample of 273 workers coming from numerous fields of work. Correlational analyses and multiples regression analyses have been conducted and have shown a significant positive relationship between the variables as well as a partial mediation effect of the basic psychological needs’ satisfaction in the relationship between procedural justice and intrinsic motivation. Results show significant positive relations between the three variables of interest and a partial mediation of the basic needs in the relation existing between procedural justice and intrinsic motivation. The role of justice for the development of intrinsic motivation at work is discussed.  相似文献

Rumination, or recursive self-focused thinking, has important implications for understanding the development and maintenance of depressive episodes. Rumination is associated with the worsening of negative mood states, greater affective responding to negative material, and increased access to negative memories. The present study was designed to use fMRI to examine neural aspects of rumination in depressed and healthy control individuals. We used a rumination induction task to assess differences in patterns of neural activation during ruminative self-focus as compared with a concrete distraction condition and with a novel abstract distraction condition in 14 participants who were diagnosed with major depressive disorder and 14 healthy control participants. Depressed participants exhibited increased activation in the orbitofrontal cortex, subgenual anterior cingulate, and dorsolateral prefrontal cortex as compared with healthy controls during rumination versus concrete distraction. Neural activity during rumination versus abstract distraction was greater for depressed than for control participants in the amygdala, rostral anterior cingulate/medial prefrontal cortex, dorsolateral prefrontal cortex, posterior cingulate, and parahippocampus. These findings indicate that ruminative self-focus is associated with enhanced recruitment of limbic and medial and dorsolateral prefrontal regions in depression.

Twinning projects between immigrants and local residents are often analyzed from the viewpoint of intercultural relations or adaptation to the host society. Our concern here is with the domestic processes at work in twinning projects implemented by community organizations and funded by the Ministère des Relations avec les Citoyens et de l'Immigration. This draws from a research project carried out among seventy-five twinned families, half of which are Quebecois and half immigrants of diverse origins. Our analysis centers around the different forms of appropriation open to actors: volunteer work, intervention, and mutual aid.  相似文献

Parenting practices have been previously linked to childhood externalizing behaviour. However, little attention has been given to the potential effect of individual personality differences among children on this relation. The current study assesses the additive effects of children's personality characteristics and explores the moderating effects of children's personality on relations between parenting practices and childhood externalizing behaviour using a proportional stratified sample of 599 nonclinical elementary‐school‐aged children. Multiple regression analyses reveal that in the mother data as well as in the father data, dysfunctional parenting and the children's personality characteristics Benevolence, Conscientiousness, and Extraversion were directly related to outcomes consistent with an additive model of their effects. Significant interactions indicate that children with low scores on Benevolence who were exposed to overreactive discipline practices exhibited higher levels of externalizing behaviour. Children characterized by low scores on Conscientiousness who were exposed to coercive parenting behaviour showed elevated levels of externalizing behaviour. These results suggest that integrating children's personality characteristics within parenting models can improve the understanding of the aetiology of childhood externalizing problem behaviour. The implications of such integrations for intervention are discussed. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献

In coincidence‐timing studies, children have been shown to respond too early to slower stimuli and too late to faster stimuli. To examine this velocity effect, children aged 6, 7.5, 9, 10.5, and adults were tested with two different velocities in a prediction‐motion task which consisted of judging, after the occlusion of the final part of its path, the moment of arrival of a moving stimulus towards a specified position. A similar velocity effect, resulting in later responses for the faster velocities than for the slower, was found primarily in the three younger groups of children (for the longer occlusion conditions: 600–1,320 milliseconds). However, this effect was not seen in all children in these groups. Individual analyses showed that this velocity effect, when present, is linked to the use of distance rather than time information, or to the confusion between these in extrapolating the occluded trajectories. The tendency to use one type of information or the other is a good predictor of accuracy and variability in this task and a good indicator of the development stage of the participants. Across development, children tend to initially use distance information with poor accuracy but relative consistency in responses. In a second stage, they use time and distance information alternatively across trials trying to find a better source of information with still poor accuracy and now great variability. In a final stage, they use time information to reach consistency and accuracy in their responses. This chronology follows the stages proposed by Savelesbergh and Van der Kamp (2000) explaining development with an initial stage of ‘freezing’ non‐optimal relationships between information and movement, then a ‘freeing’ stage during which new solutions are searched for, and finally an ‘exploiting’ stage with an optimal relationship between information and movement.  相似文献
