Two pigeons were trained on a six-key modified oddity-from-sample procedure. The stimuli were olor pictures of birds, butterflies, and human faces. Initially, the third peck on the sample key which presented one of three different bird pictures) lit only one comparison key. Every three dditional pecks on the sample illuminated another comparison key. Fifteen sample pecks produced he maximum of five comparison stimuli. A peck on the comparison key that presented the non-atching bird picture produced grain. Pecks on matching keys turned off all the comparison keys nd repeated the trial. The birds learned to peck each sample until the non-matching comparison timulus was produced, and then to peck that key. After acquisition (70%–90% accuracy), the hree bird stimuli were replaced by a new set of three bird pictures. Subsequent phases provided ew sets of bird, butterfly, and human face stimuli. Both birds showed transfer of oddity learning o the novel samples. The data suggest that the birds may have been engaging in conceptual-type oddity learning, rather than learning discrete five-key discriminations or a series of two component chains. 相似文献

A core assumption of response to instruction or intervention (RTI) models is the importance of measuring growth in achievement over time in response to effective instruction or intervention. Many RTI models actively monitor growth for identifying individuals who need different levels of intervention. A large-scale (N=23,438), two-year longitudinal study of first grade children was carried out to compare the predictive validity of measures of achievement status, growth in achievement, and their combination for predicting future reading achievement. The results indicate that under typical conditions, measures of growth do not make a contribution to prediction that is independent of measures of achievement status. These results question the validity of a core assumption of RTI models. 相似文献

This paper considers the relationship between architecture and construction management students’ overall academic abilities (as measured by Weighted Average Marks [WAMs]), their peer ratings for contributions to team design assignments (as measured by an online Self-and-Peer-Assessment [SAPA] tool), and their specific abilities as building designers (as measured by grades in individual design assignments). The research was conducted to determine whether a student’s prior academic achievements might indicate how well they will work in teams. The research demonstrates a statistically significant relationship between WAMs and SAPA ratings indicating that academically successful students more often than not make good teammates. However, the study also highlights that when peers are assessing contributions to teamwork they are assessing skills and qualities in their teammates other than overall academic ability or the ability to design well. Whilst this study is largely located within the field of design, the findings are relevant to any group work where teachers aim to design assessment that unravels group and individual contribution. 相似文献

ABSTRACTMoral Foundations Theory (MFT) and the Model of Intuitive Morality and Exemplars (MIME) contend that moral judgments are built on a universal set of basic moral intuitions. A large body of research has supported many of MFT’s and the MIME’s central hypotheses. Yet, an important prerequisite of this research—the ability to extract latent moral content represented in media stimuli with a reliable procedure—has not been systematically studied. In this article, we subject different extraction procedures to rigorous tests, underscore challenges by identifying a range of reliabilities, develop new reliability test and coding procedures employing computational methods, and provide solutions that maximize the reliability and validity of moral intuition extraction. In six content analytical studies, including a large crowd-based study, we demonstrate that: (1) traditional content analytical approaches lead to rather low reliabilities; (2) variation in coding reliabilities can be predicted by both text features and characteristics of the human coders; and (3) reliability is largely unaffected by the detail of coder training. We show that a coding task with simplified training and a coding technique that treats moral foundations as fast, spontaneous intuitions leads to acceptable inter-rater agreement, and potentially to more valid moral intuition extractions. While this study was motivated by issues related to MFT and MIME research, the methods and findings in this study have implications for extracting latent content from text narratives that go beyond moral information. Accordingly, we provide a tool for researchers interested in applying this new approach in their own work. 相似文献

Abstract One hundred high school girls (N = 20 per group) were initially given 10 trials on the Bachman ladder-climb task; each group was given a different length of lay-off (10 min., or 1 day, or 1 week, or 4 weeks, or 13 weeks) before being retested with another 10 trials. Correlations between individual differences across the lay-off decreased as the length of the lay-off period increased (from r = .89 to r = .69). Correlations between adjacent trials remained relatively constant at r =.90 as practice progressed. As remoteness increased, the relation decreased regularly, from r =.92 to r =.68. Individuals became increasingly different from each other as a result of motor learning; intraindividual variance did not change appreciably. 相似文献
