A word's predictability in context has a well-established effect on fixation durations in reading. To investigate how this effect is manifested in distributional terms, an experiment was carried out in which subjects read each of 50 target words twice, once in a high-predictability context and once in a low-predictability context. The ex-Gaussian distribution was fit to each subject's first-fixation durations and single-fixation durations. For both measures, the μ parameter increased when a word was unpredictable, while the τ parameter was not significantly affected, indicating that a predictability manipulation shifts the distribution of fixation durations but does not affect the degree of skew. Vincentile plots showed that the mean ex-Gaussian parameters described the typical distribution shapes extremely well. These results suggest that the predictability and frequency effects are functionally distinct, since a frequency manipulation has been shown to influence both μ and τ. The results may also be seen as consistent with the finding from single-word recognition paradigms that semantic priming affects only μ. 相似文献

Visual search for a target object is facilitated when the object is repeatedly presented within an invariant context of surrounding items ("contextual cueing"; Chun & Jiang, Cognitive Psychology, 36, 28-71, 1998). The present study investigated whether such invariant contexts can cue more than one target location. In a series of three experiments, we showed that contextual cueing is significantly reduced when invariant contexts are paired with two rather than one possible target location, whereas no contextual cueing occurs with three distinct target locations. Closer data inspection revealed that one "dominant" target always exhibited substantially more contextual cueing than did the other, "minor" target(s), which caused negative contextual-cueing effects. However, minor targets could benefit from the invariant context when they were spatially close to the dominant target. In sum, our experiments suggest that contextual cueing can guide visual attention to a spatially limited region of the display, only enhancing the detection of targets presented inside that region. 相似文献

Background . Although recent research has provided evidence for the predictive validity of personality traits in academic settings, the path to an improved understanding of the nature of personality influences on academic achievement involves a reconceptualization of both criterion and predictor construct spaces. Aims . For the criterion space, one needs to consider student behaviours beyond grades and level of educational attainment, and include what the student does among other things outside of the classroom. For the predictor space, it is possible to bring some order to the myriad personality constructs that have been developed over the last century, by focusing on common variance among personality and other non‐ability traits. Methods . We review these conceptual issues and several empirical studies. Conclusions . We demonstrate the possible increments in understanding non‐ability determinants of academic achievement that may be obtained by focusing on areas where there is a theoretical convergence between predictor and criterion spaces. 相似文献

Many studies demonstrate that mortality salience can increase negativity toward outgroups but few have examined variables that mitigate this effect. The present research examined whether subtly priming people to think of human experiences shared by people from diverse cultures increases perceived similarity of members of different groups, which then reduces MS-induced negativity toward outgroups. In Study 1, exposure to pictures of people from diverse cultures engaged in common human activities non-significantly reversed the effect of MS on implicit anti-Arab prejudice. In Study 2, thinking about similarities between one's own favorite childhood memories and those of people from other countries eliminated MS-induced explicit negative attitudes toward immigrants. In Study 3, thinking about similarities between one's own painful childhood memories and those of people from other countries eliminated the MS-induced reduction in support for peace-making. Mediation analyses suggest the effects were driven by perceived similarity of people across cultures. These findings suggest that priming widely shared human experiences can attenuate MS-induced intergroup conflict. 相似文献

Despite much commentary on "psychiatric skepticism", there remains a dearth of appropriate psychometric scales for the measurement of this concept. To overcome this limitation, the present study examined the psychometric properties and correlates of the recently developed Psychiatric Scepticism Scale (PSS). A total of 564 individuals from the community in London, England, completed the PSS along with measures of anti-scientific attitudes, attitudes to authority, knowledge of mental health disorders, and demographics. Results showed that the PSS has a one-dimensional factor structure with very good internal consistency. In addition, it showed adequate convergent (anti-scientific attitudes, knowledge of mental health disorders) and construct validity (attitudes to authority, religiosity). Results also showed that there were small but significant differences in psychiatric skepticism by ethnicity and education, but not sex or previous diagnosis of mental health disorder. These results confirm that the PSS has adequate psychometric properties for the measurement of psychiatric skepticism. 相似文献

A total of 383 participants (aged 19 to 66 years) completed the Raven's Progressive Matrices, the Myers‐Briggs Type Indicator (MBTI), the Fundamental Interpersonal Relations Orientation‐Behavior (FIRO‐B), and the California Psychological Inventory‐434 (CPI‐434). Results showed that IQ was positively correlated with perceiving (MBTI), control (FIRO‐B), intellectual efficiency (CPI‐434), achievement via independence (CPI‐434), and negatively correlated with sensing (MBTI), internality (CPI‐434) and norm‐favouring (CPI‐434), supporting the majority of the hypotheses. Participants' age was correlated with many measures, particularly intelligence and accounted for a third of the variance in IQ scores. Limitations are considered. 相似文献

In three experimental tasks Stephen and Mirman (2010) measured gaze steps, the distance in pixels between gaze positions on successive samples from an eyetracker. They argued that the distribution of gaze steps is best fit by the lognormal distribution, and based on this analysis they concluded that interactive cognitive processes underlie eye movement control in these tasks. The present comment argues that the gaze step distribution is predictable based on the fact that the eyes alternate between a fixation state in which gaze is steady and a saccade state in which gaze position changes rapidly. By fitting a simple mixture model to Stephen and Mirman's gaze step data we reveal a fixation distribution and a saccade distribution. This mixture model captures the shape of the gaze step distribution in detail, unlike the lognormal model, and provides a better quantitative fit to the data. We conclude that the gaze step distribution does not directly suggest processing interaction, and we emphasize some important limits on the utility of fitting theoretical distributions to data. 相似文献

This study explored a longitudinal data set of nearly 5000 adults examining the effects of childhood cognitive ability (measured at age 11), parental social class (measured at birth), and personality on current occupational prestige (all measured at age 50), taking account the effects of education and the previous occupational levels (both measured at age 33). Participants' levels of occupational attainment significantly went up from age 33 to age 50. Correlational analysis showed childhood cognitive ability, parental social class, education and occupation, and personality traits (openness, conscientiousness, extraversion, emotional stability) were all significantly associated with current occupational prestige. The strongest correlates of current occupational levels were educational qualifications, followed by childhood cognitive ability, parental social class, and personality traits. Structural equation modelling showed that for the change of occupation over 17 years, the strongest predictor was education, followed by childhood intelligence. Personality traits (extraversion, conscientiousness, and openness) had modest but significant influence in the upgrading of occupational attainment over the period of time, and parental social status predicted occupational change mediated through education and initial occupational levels. Education and childhood intelligence are more powerful predictors of current occupational prestige than personality factors or family social background. The implications for policy making and equal opportunities for education are discussed. 相似文献

School connectedness is central to the long term well-being of adolescents, and high quality parent–child relationships facilitate
school connectedness. This study examined the extent to which family relationship quality is associated with the school connectedness
of pre- and early teenagers, and how this association varies with adolescent involvement in peer drinking networks. The sample
consisted of 7,372 10–14 year olds recruited from 231 schools in 30 Australian communities. Participants completed the Communities that Care youth survey. A multi-level model of school connectedness was used, with a random term for school-level variation. Key independent
variables included family relationship quality, peer drinking networks, and school grade. Control variables included child
gender, sensation seeking, depression, child alcohol use, parent education, and language spoken at home. For grade 6 students,
the association of family relationship quality and school connectedness was lower when peer drinking networks were present,
and this effect was nonsignificant for older (grade 8) students. Post hoc analyses indicated that the effect for family relationship
quality on school connectedness was nonsignificant when adolescents in grade 6 reported that the majority of friends consumed
alcohol. The results point to the importance of family-school partnerships in early intervention and prevention. 相似文献
