Orthographic transparency metrics for opaque or deep languages, such as French and English, have tended to focus on feedforward and/or feedback directions, with claims made for the influence of both on reading. In the present study, data for five transparency metrics for southern British English, three of which are neither feedforward nor feedback, are presented, demonstrating the complex relationships between the metrics and offering an explanation for feedback effects in children’s reading accuracy. The structure of such metrics from a variety of corpus sizes and origins is investigated, and it is concluded that large corpus sizes do not make a substantial contribution to the value of such metrics, when compared with smaller samples, and that adult and child corpuses have very similar profiles. Probabilities of occurrence for the phonemes, graphemes, and sonographs in this study may be downloaded from brm.psychonomic-journals.org/content/supplemental.  相似文献

We designed and tested a novel technology that enables us to capture the entire stream of behavior in perseverative reaching tasks. Beyond fitting the criteria of the conventional A-not-B task, the novel technology gives us better access to the core features of perseverative reaching, such as timing, behavior history, and reinforcement. The technology allows us to quantitatively manipulate reinforcement characteristics, to accurately program onsets, delays, and stimulus durations as well as locations and salience of the targets, and to automatically record the number of reaches to each target and compute timing. We did a validation study on this new technology, investigating the influence of a number of novel factors on perseverative reaching. We replicated the A-not-B phenomenon and associated developmental changes. In addition, results demonstrated that the new technology offers insights into infants' behavior beyond the first reaching action. Moreover, data collection is fully automated, yielding precise, quantitative data. Future studies using this technology will capitalize on the salient advantages of this technology to more precisely measure goal-directed actions and understand the development of reaching skill.  相似文献

This article reports a calibration procedure that enables researchers to track movements of the eye while allowing relatively unrestricted head and/or body movement. The eye—head calibration algorithm calculates fixation point based on eye-position data acquired by a head-mounted eyetracker and corresponding head-position data acquired by a 3-D motion-tracking system. In a single experiment, we show that this procedure provides robust eye-position estimates while allowing free head movement. Although several companies offer ready-made systems for this purpose, there is no literature available that makes it possible for researchers to explore the details of the calibration procedures used by these systems. By making such details available, we hope to facilitate the development of cost-effective, nonproprietary eyetracking solutions.  相似文献

Prior research often emphasized a stimulus‐based or bottom‐up view of product category representations. In contrast, we emphasize a more purposeful, top‐down perspective and examine categories that consumers might construct in the service of salient (i.e., highly accessible) goals. Specifically, we investigate how the point of view imposed by salient consumer goals might affect category representations assessed by participants’ similarity judgments of food products. A key factor in our study is that we examine both individual and situational sources of variability in goal salience. In addition, we also vary the surface‐level, visual resemblance of the stimulus pairs of foods used in the study. The results suggest that personal goals (e.g., health) and situational goals (e.g., convenience) act in conjunction and exert a systematic impact on category representations. Both types of goals, when salient, enhanced the perceived similarity of goal‐appropriate products and reduced the similarity of product pairs when only one product was ideal for the particular goal. The similarity‐enhancing effect was most pronounced when the surface resemblance between the products was low, and the similarity‐diminishing effect was more apparent when surface resemblance was high. Implications are discussed for current theoretical assumptions regarding categorization in consumer research.  相似文献

Maternal psychopathology has long been recognized as a risk factor for psychopathology in offspring; however, some resilient youth achieve a favorable outcome in the presence of maternal psychopathology. We identified factors that predicted resilience among youth who were exposed to adverse life events, and also examined whether the same factors protected youth against maternal psychopathology and adverse life events. Main and interaction effects of child and family factors were examined employing cross-sectional data from a household probability sample of 1285 youth aged 9 through 17 collected at four sites. On average, children exhibited a greater degree of resilience when they had higher IQ, closer parental monitoring, better family functioning, higher educational aspiration, and were female. Interaction between maternal psychopathology and IQ was significant, and there was a trend between maternal psychopathology and gender. A higher IQ is a protective factor against both maternal psychopathology and adverse life events; whereas being a girl seems to be a protective factor against maternal psychopathology, but not adverse life events.  相似文献

In this study, the romantic beliefs, styles of relating, sex-role traits, and social self-efficacy of 433 young people from three cultural groups were assessed and their links with relationship status and loneliness explored. A majority cultural group (Anglo-Australians) was compared with two minority groups (Chinese- and Southern European-background young people) within the same society. Chinese-background youth were less likely to be in a romantic relationship and more likely to be lonely than Anglo-Australian or Southern European-Australians. Greater loneliness was associated with non-secure relationship styles, lower social self-efficacy, and lower scores on psychosocial femininity and masculinity. Predictors of relationship status included romantic attitudes and relationship styles. Some evidence pointed to stronger social efficacy and more secure relationship styles being associated with greater acculturation but it was rather weak and inconsistent.  相似文献

Three studies examined how people maintain their self-images when they face threat to interpersonal aspects of the self. In Studies 1 and 2, we found evidence that low self-esteem people lower their estimates of their performance when they expect immediate feedback in order to protect themselves from the interpersonal threat inherent in such feedback, and that self-affirmation reduces this tendency among low self-esteem people. In Study 3, we found that when people are self-affirmed they are more likely to engage in upward social comparisons and less likely to engage in downward social comparisons. Together these findings suggest that people can cope with threats to interpersonal aspects of the self by affirming other important aspects of the self.  相似文献

From the rapidly growing literature on bullying, it is increasingly recognised that peer relationship problems as manifested in being bullied are associated with low self‐esteem. However, the literature on self‐esteem in relation to children who bully others is controversial. The objective of this paper is to elucidate further our understanding of the relationship between self‐concept and bullying behaviour. Data from a nationwide study of bullying behaviour carried out in Ireland during 1993‐1994 have been reviewed. The relevant results from 8,249 school children aged 8 to 18 years are presented. The paper examines the global and dimensional nature of self‐esteem and how it relates to children and adolescents who either have been victimised or bullied others. A distinction is made between “pure victims,” “pure bullies,” and children and adolescents who were both bullied and who bullied others. In other words, pure victims were those who had not bullied others, and pure bullies had not themselves been bullied. Those who were both bullied and bullied others were subdivided further into victims who bully occasionally, sometimes, and frequently and bullies who are victimised, occasionally, sometimes, and frequently. The results show that children of both primary and post‐primary age who were involved in bullying as victims, bullies, or both had significantly lower global self‐esteem than did children who had neither bullied nor been bullied. However, the pure bullies, in contrast to the pure victims, placed the same value on their physical attractiveness and attributes and on their popularity as did their peers who had not bullied others or been bullied. The bully‐victims of all ages had the lowest self‐esteem of the subgroups in the study. Also, the more frequently children were victimised or bullied others, the lower was their global self‐esteem. The typology and frequency of bullying and the age of the children when they were involved in bullying influenced the status of the specific domains of self‐esteem. There were, e.g., significant differences in anxiety between the pure bullies of post‐primary age and their peers who had not bullied others or been bullied. The post‐primary children who bullied most frequently were the least anxious. The results indicate that high self‐esteem protects children and adolescents from involvement in bullying. Thus, in view of the strong relationship between self‐esteem and bullying that has been found in the present paper, it is recommended that top priority be given by parents and teachers to preventing and reducing feelings of poor self‐worth among children and adolescents.

Although prior studies have found that people generally underweight advice from others, such discounting of advice is not universal. Two studies examined the impact of task difficulty on the use of advice. In both studies, the strategy participants used to weigh advice varied with task difficulty even when it should not have. In particular, the results show that people tend to overweight advice on difficult tasks and underweight advice on easy tasks. This pattern held regardless of whether advice was automatically provided or whether people had to seek it out. The paper discusses implications for the circumstances under which people will be open to influence by advisors. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献
