空间行为关系类比匹配中客体相似性的作用

客体相似性在类比匹配中的作用,是一直存在着争论的问题。该研究通过交叉匹配结合与分离的材料设计,控制类比源和类比目标之间不同相似性,探讨了客体相似性在儿童和成人空间行为关系类比匹配中的作用。实验一通过让儿童和成人完成单目标匹配任务,检验客体相似性对儿童和成人类比匹配影响的不同。实验二采用眼动技术对客体相似性在成人类比匹配过程中的作用进行分区域探讨。结果发现,客体相似性影响儿童空间行为关系类比匹配的成绩,但不影响成人的成绩。成人类比匹配的过程受到结合在关系结构之内的客体相似性的影响。我们提出优先-限制调整观点解释客体相似性在类比匹配中的作用。     

Ten-year-old girls' and boys' body composition and peer victimization experiences: prospective associations with body satisfaction

This study examined prospective associations between 10-year-olds’ weight and height, their perception of shape and stature, frequent experiences of peer victimization, and different aspects of body esteem at age 13. Participants were 474 girls and 400 boys participating in a two-wave longitudinal questionnaire study. Main results were that whereas actually being heavier built at age 10 was associated with girls’ increments in body dissatisfaction, the mere perception of being too heavy was associated with boys’ poorer body satisfaction. Also, boys who believed that they were too short were more dissatisfied at follow-up. Whereas frequent peer victimization had long-term associations with girls’ weight-esteem, teasing targeted towards appearance was associated with boys’ more negative beliefs about what others think about their appearance. Finally, participants had become significantly more dissatisfied at age 13, suggesting that this is a time in life when both girls and boys risk becoming increasingly critical towards their appearance.     

Self-Perceived Competence as a Mediator Between Maternal Feedback and Depressive Symptoms in Adolescents

Self-report, other-report, clinical interview, and behavioral observations of evaluative maternal feedback (e.g., positive feedback, criticism), adolescent depressive symptoms, and self-perceived competence were obtained from 72 adolescents and their mothers. Most path analyses supported the hypothesis that adolescent self-perceived competence completely mediates the relation between negative maternal feedback and adolescent depressive symptoms, even after controlling for prior levels of depression. Consistent with Cole's competency-based model of depression (D. A. Cole, 1990), these results suggest that high levels of negative maternal feedback (coupled with low levels of positive feedback) are associated with adolescent negative self-perceptions, which in turn place adolescents at risk for depressive symptoms.     

Sustainable and responsible design from a christian worldview

Many aspects of design require engineers to make choices based on non-quantifiable personal perspectives. These decisions touch issues in aesthetics, ethics, social impact, and responsibility and sustainability. Part of Baylor University’s mission is to provide a learning community in which Christian life values and worldviews might be integrated into academic disciplines. In view of this institutional commitment, members of the Engineering faculty are investigating how Christian worldviews might interact with elements of engineering design in such a way as to produce uniquely Christian insights and inform the non-quantifiable aspects of the engineering process.

Evil intent and design responsibility

Mass casualty attacks in recent years have demonstrated the need to include “evil intent” as a design consideration. Three recent actual or potential weapons of mass destruction (WMD) attacks did not involve nuclear bombs or other devices designed as weapons, but rather benign objects used with evil intent. Just as unplanned events such as hurricanes, earthquakes, fires, and user misuse have been codified into design requirements based on the likelihood and potential impact of the event, “evil intent” has to become part of the design process for buildings, vehicles, equipment, and other items. The endstate should be reasonable additions to existing codes and standards such that it is clear what is and is not designed for. In the absence of specific design guidance, professionals with appropriate expertise can assess potential for “evil intent” and provide recommendations to design out or warn against this potential harm to public safety, particularly when codified requirements are not present.

The transformation of consequential functions in accordance with the relational frames of more-than and less-than

Across three experiments, the transformation of consequential functions in accordance with a seven-member relational network (A-B-C-D-E-F-G) was investigated. In this network, the relational rankings ranged from A, ranked the least, to G, ranked the most. In the first phase, contextual cues for more-than and less-than were established by training participants across multiple exemplars to select comparisons containing larger quantities in the presence of the former cue, and fewer quantities in the presence of the latter cue. Participants then were trained in six conditional discriminations (i.e., AD, F>E, and G>F) with the contextual cues as samples and nonsense words as comparisons, and all possible derived relations were tested (e.g., B相似文献   

Callous–Unemotional Traits in Predicting the Severity and Stability of Conduct Problems and Delinquency

The current study tests whether the presence of callous–unemotional (CU) traits designates a group of children with conduct problems who show an especially severe and chronic pattern of conduct problems and delinquency. Ninety-eight children who were selected from a large community screening of school children in grades 3, 4, 6 and 7 were followed across four yearly assessments. Children with conduct problems who also showed CU traits exhibited the highest rates of conduct problems, self-reported delinquency, and police contacts across the four years of the study. In fact, this group accounted for at least half of all of the police contacts reported in the sample across the last three waves of data collection. In contrast, children with conduct problems who did not show CU traits continued to show higher rates of conduct problems across the follow-up assessments compared to non-conduct problem children. However, they did not show higher rates of self-reported delinquency than non-conduct problem children. In fact, the second highest rate of self-reported delinquency in the sample was found for the group of children who were high on CU traits but without conduct problems at the start of the study.     

The role of secondary covariates when estimating latent trait population distributions

The U.S. National Assessment of Educational Progress (NAEP), the Third International Mathematics and Science Study (TIMSS), and the U.S. Adult Literacy Survey collect probability samples of students (or adults) who are administered brief examinations in subject areas such as mathematics and reading (cognitive variables), along with background demographic (primary) and educational environment (secondary) questions. The demographic questions are used in the primary reporting, while the numerous explanatory secondary variables, or covariates, are only directly utilized in subsequent secondary analyses. The covariates are also used indirectly to create the plausible values (multiple imputations) that are an integral part of analyses because of the use of sparse matrix sampling of cognitive items. The improvement in the precision of the primary reporting due to the inclusion of the covariates is assessed here and contrasted with the precision of reporting using plausible values created using only the primary demographic variables.The results demonstrate that the improvement in precision depends on the matrix sampling designs for the cognitive assessments. The improvements range from essentially none for the most common designs, to moderate for some less common designs. Consequently, two potential changes in the reporting procedures that could improve the statistical and operational efficiency of primary reporting are (a) eliminate or reduce the collection of covariates and increase the number of cognitive items, (b) to avoid delays, eliminate the covariates from the creation of plausible values used for the primary reports, but include them later when creating public-use files for secondary analyses. The potential improvements in statistical and operational efficiency must be weighed against the intrinsic interest in the covariates, and the potential for small discrepancies in the primary and secondary reporting.Thanks to Donald Rubin, Robert Mislevy, and John Barnard for their helpful comments and computing assistance.

Students Aggress Against Professors in Reaction to Receiving Poor Grades: An Effect Moderated by Student Narcissism and Self‐Esteem

Laboratory evidence about whether students’ evaluations of teaching (SETs) are valid is lacking. Results from three (3) independent studies strongly confirm that "professors" who were generous with their grades were rewarded for their favor with higher SETs, while professors who were frugal were punished with lower SETs (Study 1, d = 1.51; Study 2, d = 1.59; Study 3, partial η² = .26). This result was found even when the feedback was manipulated to be more or less insulting (Study 3). Consistent with laboratory findings on direct aggression, results also indicated that, when participants were given a poorer feedback, higher self‐esteem (Study 1 and Study 2) and higher narcissism (Study 1) were associated with them giving lower (more aggressive) evaluations of the "professor." Moreover, consistent with findings on self‐serving biases, participants higher in self‐esteem who were in the positive grade/feedback condition exhibited a self‐enhancing bias by giving their "professor" higher evaluations (Study 1 and Study 2). The aforementioned relationships were not moderated by the professor's sex or rank (teaching assistant vs.professor). Results provide evidence that (1) students do aggress against professors through poor teaching evaluations, (2) threatened egotism among individuals with high self‐esteem is associated with more aggression, especially when coupled with high narcissism, and (3) self‐enhancing biases are robust among those with high self‐esteem.
