词切分对印-英双语者阅读影响的眼动研究

以25名印-英双语者为被试,采用EyeLink2000眼动仪,探讨词切分对印-英双语者阅读的影响。实验一要求被试阅读印地语句子,实验二要求被试阅读英语句子,词切分方式有三种：正常条件、无空格隔词加灰条件和无空格条件。结果发现：（1）对印-英双语者阅读自己的两种官方语言来说,空格因素在其阅读中发挥着积极作用,删除空格会明显影响他们的阅读;（2）在无空格隔词加灰条件和无空格条件下,印-英双语者阅读英语时下降的速度显著低于阅读印地语的,这表明空格因素的作用会受语言特点的制约。     

When spiders appear suddenly: spider-phobic patients are distracted by task-irrelevant spiders

Fear is thought to facilitate the detection of threatening stimuli. Few studies have examined the effects of task-irrelevant phobic cues in search tasks that do not involve semantic categorization. In a combined reaction time and eye-tracking experiment we investigated whether peripheral visual cues capture initial attention and distract from the execution of goal-directed eye movements. Twenty-one spider-phobic patients and 21 control participants were instructed to search for a color singleton while ignoring task-irrelevant abrupt-onset distractors which contained either a small picture of a spider (phobic), a flower (non-phobic, but similar to spiders in shape), a mushroom (non-phobic, and not similar to spiders in shape), or no picture. As expected, patients' reaction times were longer on trials with spider distractors. However, eye movements revealed that this was not due to attentional capture by spider distractors; patients more often fixated on all distractors with pictures, but their reaction times were delayed by longer fixation durations on spider distractors. These data do not support automatic capture of attention by phobic cues but suggest that phobic patients fail to disengage attention from spiders.     

Why good thoughts block better ones: the mechanism of the pernicious Einstellung (set) effect

The Einstellung (set) effect occurs when the first idea that comes to mind, triggered by familiar features of a problem, prevents a better solution being found. It has been shown to affect both people facing novel problems and experts within their field of expertise. We show that it works by influencing mechanisms that determine what information is attended to. Having found one solution, expert chess players reported that they were looking for a better one. But their eye movements showed that they continued to look at features of the problem related to the solution they had already thought of. The mechanism which allows the first schema activated by familiar aspects of a problem to control the subsequent direction of attention may contribute to a wide range of biases both in everyday and expert thought - from confirmation bias in hypothesis testing to the tendency of scientists to ignore results that do not fit their favoured theories.     

Social Change Movements and the Struggle Over Meaning-Making: A Case Study of Domestic Violence Narratives

Social movement theorists have emphasized the important role of meaning-making for social change movements (e.g., D. A. Snow and R. D. Benford, 1992, In: A. D. Morris & C. M. Mueller (Eds.) Frontiers in social movement theory. Yale University Press, New Haven, CT, pp 133-155; C. M. Mueller, 1992, In: A. D. Morris & C. M. Mueller (Eds.) Frontiers in social movement theory. Yale University Press, New Haven, CT, pp 3-26). Using the domestic violence movement as a case study, this study undertakes a close analysis of advocates' narratives about the phenomenon of domestic violence. This analysis sheds light on the current status of the movement as a social change movement attempting to promote alternative understandings of domestic violence as a social, rather than individual, problem. Study findings provide some evidence that the domestic violence movement has become increasingly de-politicized by documenting a range of narratives that convey an apolitical, degendered, individual-level analysis of domestic violence.     

Studying the variability of handwriting patterns using the Kinematic Theory

The variability observed in handwriting patterns is analyzed from the perspective of integrating the resulting motor control knowledge in the design of more powerful handwriting recognizers in personal digital assistants (PDAs) and smartphones. Using the highest representational level of the Kinematic Theory of Rapid Human Movement, the Sigma-Lognormal model, this article reports basic theoretical and practical results that could be taken into account in the design of such systems. The main movement variability introduced by the neuromuscular system (NMS) and induced through the scheduling of motor tasks by the central nervous system (CNS) is divided into global and local fluctuations. From a fiducial action plan decoded by this model, a wide range of handwriting distortions are artificially generated by acting on the Sigma-Lognormal parameters. The resulting patterns are studied to understand scale changes and rotational deformations, the two basic features that a recognizer has to take into account. An experiment based on the writing of the same word by six writers is also reported. The results, obtained by an ANOVA analysis, corroborate the predictions and support the relevance of the Kinematic Theory for the analysis and synthesis of handwriting disruptions. These findings consolidate the results of previous studies on single strokes using the Sigma-Lognormal model. Overall, this report provides new insights into our understanding of motor control, as well as into practical cues for the development of huge databases of letters and words to train and test on-line handwriting classifiers and recognizers.     

Influence of handedness and bilateral eye movements on creativity

We investigated the effects of increased inter-hemispheric interaction (IHI) on five creativity dimensions (appropriateness, detail, categorical distinctiveness, fluency, and originality) of the Alternate Uses Task. Two methods were used to indicate degree of IHI. Trait IHI was indicated by individual differences in handedness, mixed-handers showing greater IHI than strong-handers. State IHI was directly manipulated by central (control group) and bilateral viewing conditions of a 30 s eye movement task (EM). Results indicate significantly higher creativity for mixed-handers, as compared to strong-handers, for all five sub-scores separately and linearly combined. Bilateral EM increased originality and categorical distinctiveness (i.e., flexibility) of strong-handers, but had no effect on mixed-handers. Strong-handers in the bilateral EM group were not different from mixed-handers. Additionally, the bilateral EM effect on strong-handers had different durations for originality (up to 7–9 min) and categorical distinctiveness (up to 3 min). The results suggest that greater IHI can facilitate creativity of strong-handers, but that the characteristically higher IHI of mixed-handers was unaffected by the bilateral EM manipulation.     

The moderating effect of parental warmth on the association between spanking and child aggression: a longitudinal approach

Using data from the Early Head Start Research and Evaluation Study, this study analysed the stability of child aggressive behaviour beginning in infancy and tested whether spanking when the child was 36 months was associated with aggressive child behaviour among three ethnic groups and whether maternal warmth moderated the effect of spanking on aggressive behaviour in each ethnic group at 36 months, after controlling for earlier aggressive behaviour. Participants included 693 Hispanic parent–child dyads, 1013 African‐American dyads and 1086 Caucasian dyads who met qualifications for participation in the Early Head Start programme. Findings suggest that infant temperament was associated with aggressive behaviour at 24 and 36 months and that child aggression remained stable. Among the three ethnic groups, spanking was only associated with aggressive behaviour for children who had Caucasian mothers and maternal warmth did not moderate the effect of spanking on aggressive behaviour.

Eye movement correlates of younger and older adults' strategies for complex addition

This study examined performance measures and eye movements associated with complex arithmetic strategies in young and older adults. Participants added pairs of three-digit numbers using two different strategies, under choice and no-choice conditions. Older adults made more errors but were not significantly slower than young adults, and response times and errors showed no interaction between age and the number of carries. Older adults chose strategies less adaptively than young adults. Eye movements were consistent with use of required strategies on no-choice trials and reported strategies on choice trials. Eye movement data also suggested that young adults more successfully distinguished between strategies. Implications of these findings for understanding aging effects in complex arithmetic are discussed.     

Executive career management: Switching organizations and the boundaryless career

There has been little research examining executives who change jobs by specifically following these individuals both before and after their employer changes. By incorporating research on the boundaryless career [Arthur, M. B., & Rousseau, D. M. (Eds.). (1996). The boundaryless career: A new employment principle for a new organizational era. New York: Oxford University Press; Sullivan, S. E., & Arthur, M. B. (2006). The evolution of the boundaryless career concept: Examining physical and psychological mobility. Journal of Vocational Behavior, 69, 19-29] and applying Frank’s theory of relative standing (1985), this study examined factors that may cause executives to change jobs in the context of managing their careers. Our findings revealed that factors, such as age and compensation, were related to the likelihood of job movements as well as declining organizational health. Post-hoc analyses also indicated that executive job-changers received significantly greater increases in total compensation and were more likely to receive increases in organizational status.
