We present an application to study task-oriented reading processes called Read&Answer. The application mimics paper-and-pencil situations in which a reader interacts with one or more documents to perform a specific task, such as answering questions, writing an essay, or similar activities. Read&Answer presents documents and questions with a mask. The reader unmasks documents and questions so that only a piece of information is available at a time. This way the entire interaction between the reader and the documents on the task is recorded and can be analyzed. We describe Read&Answer and present its applications for research and assessment. Finally, we explain two studies that compare readers’ performance on Read&Answer with students’ reading times and comprehension levels on a paper-and-pencil task, and on a computer task recorded with eye-tracking. The use of Read&Answer produced similar comprehension scores, although it changed the pattern of reading times.  相似文献

Psychometric properties of an instrument for assessing cyber-sex addiction. Cyber-sex addiction is a ?new pathology? whose prevalence has grown rapidly in recent years. Therefore, it is important to have validated assessment instruments. The aim of this study was the adaptation and validation of the Internet Sex Screening Test (ISST) for its use in a Spanish population. The instrument was administered to 1239 Spanish college students. The results yielded five components that account for 47.5% of the variance. Internal consistency was .88 and temporal stability was .84. Moreover, the instrument had adequate convergent and discriminant validity and was related to other behaviors such as the use of pornography, internet addiction, number of hours online and sexual frequency. Therefore, this tool is proposed as an appropriate measure to assess cyber-sex addiction.  相似文献

A number of recent studies have questioned the conventional view regarding the existence of income-related inequalities in depression and have suggested that other factors have a more marked impact, most notably those socio-environmental effects linked to professional status and educational attainment. This paper seeks to measure and decompose the degree of socio-economic inequality in the factors underlying reported depression by drawing on data from Spain (Spanish National Health Survey, 2003), a country in which mental care coverage is somewhat limited, but where a marked social transformation has been apparent in recent decades. Contrary to recent evidence, our findings point towards the existence of significant income-related inequalities in the prevalence of reported (diagnosed) depression. However, the results from our decomposition analysis are more mixed. While a modest proportion of overall inequalities (6–13%) is accounted for by income alone, labour status, demographics and education appear to be more relevant. However, when controlling for potential endogeneity between income and depression by using instrumental variables (IV), income is found to account for more than 50% of overall inequality in reported depression.

Recently, researchers reported a bias for placing agents predominantly on the left side of pictures. Both hemispheric specialization and cultural preferences have been hypothesized to be the origin of this bias. To evaluate these hypotheses, we conducted a study with participants exposed to different reading and writing systems: Germans, who use a left-to-right system, and Israelis, who use a right-to-left system. In addition, we manipulated the degree of exposure to the writing systems by testing preschoolers and adults. Participants heard agent-first or recipient-first sentences and were asked to draw the content of the sentences or to arrange transparencies of protagonists and objects such that their arrangement depicted the sentences. Although preschool-age children in both countries showed no directional bias, adults manifested a bias that was consistent with the writing system of their language. These results support the cultural hypothesis regarding the origin of spatial-representational biases.  相似文献

Creationism implies that God imbued each category with a unique nature and purpose. These implications closely correspond to what some cognitive psychologists define as an essentialistic and teleological stance towards categories. This study assessed to what extent the belief in God as creator of categories is related to the mappings of these stances to categories in different domains. Israeli secular and orthodox Jewish 1st and 5th graders responded to questions assessing these three types of beliefs. The results revealed that secular children did not differ from orthodox children with respect to their essentialist beliefs about the stability of animal category membership, and their teleological construal of artifacts. In turn, secular children did differ from orthodox children with respect to their essentialist beliefs about the stability of social category membership, and their teleological construal of both animal and social categories. These findings intimate that while essentialist beliefs about animals, and teleological beliefs about artifacts do not require cultural input in order to emerge, essentialist beliefs about social categories, and teleological beliefs about both animal and social categories do.  相似文献

Category learning can be achieved by identifying common features among category members, distinctive features among non-members, or both. These processes are psychologically and computationally distinct, and may have implications for the acquisition of categories at different hierarchical levels. The present study examines an account of children’s difficulty in acquiring categories at the subordinate level grounded on these distinct comparison processes. Adults and children performed category learning tasks in which they were exposed either to pairs of objects from the same novel category or pairs of objects from different categories. The objects were designed so that for each category learning task, two features determined category membership whereas two other features were task irrelevant. In the learning stage participants compared pairs of objects noted to be either from the same category or from different categories. Object pairs were chosen so that the objective amount of information provided to the participants was identical in the two learning conditions. We found that when presented only with object pairs noted to be from the same category, young children (6 ? YO ? 9.5) learned the novel categories just as well as older children (10 ? YO ? 14) and adults. However, when presented only with object pairs known to be from different categories, unlike older children and adults, young children failed to learn the novel categories. We discuss cognitive and computational factors that may give rise to this comparison bias, as well as its expected outcomes.  相似文献

An experimenter-administered intervention involving prompts, self-monitoring, permanent product collection, rewards for plaque reduction, and corrective feedback was used to improve the flossing skills of four 7- to 11-year-old children. Parents were subsequently trained in the reward and feedback procedures to facilitate maintenance. In a multiple baseline across subjects design, all four subjects snowed improvement in plaque between teeth during experimenter-administered intervention. Three subjects maintained low plaque levels during the 3- to 4-month parent-administered rewards and feedback follow-up condition. Improved plaque levels on nontargeted tooth surfaces also were observed. Pediatric dentistry applications are discussed.  相似文献

This study presents self-report cross-sectional and longitudinal data on associations between drug use, suicide ideation, and attempts in a multiethnic sample of seventh- and eighth-grade male adolescents attending school in the greater Miami, Florida, area. African Americans had the highest prevalence of 6-month ideation (20.5%), and Haitians had the highest attempts (11.4%). For the total sample, tranquilizers had the highest odds ratio for ideation (3.4), and PCP for attempts (6.2). Psychoactive drug-use was consistently related to attempts among Hispanics, white non-Hispanics, and African Americans. Acculturation strains interacted with cocaine and crack to predict suicide attempts among Hispanic respondents.  相似文献

Many believe that the lack of correlation between happiness and income, first discovered by Richard Easterlin in 1974, entails the conclusion that well-being policies should be made based on happiness measures, rather than income measures. I argue that distinguishing between how well-being is characterized and how that characterization is measured introduces ways of denying the conclusion that policies should be made based on happiness measures. It is possible to avoid the conclusion either by denying that well-being hedonism is true or by denying that happiness measures are a better way of operationalizing hedonism than income measures are. By making these possibilities explicit, we find that less hinges on whether income and happiness are correlated than is often thought.  相似文献
