Cognitive brain potentials in kindergarten children with subtyped risks of reading retardation

Cognition-related brain responses to meaningful and meaningless figures were registered in 5-year-old kindergarten children who either had been subtyped as being at-risk of developing an L- or P-type dyslexia (LAL versus LAP) or who were not at-risk. While identifying, naming, or categorizing pictures, event-related potentials (ERP) were registered. Three cognition-related components were found: the N460, the P780, and the Slow Wave (SW). LAP-children produced weak N460 activity across tasks, whereas LAL children, and to a lesser degree, non-risk children produced robust task-dependent activity. This finding may indicate that LAP-children lack semantic input while processing the figures. P780 latencies to frequently occurring figures were found hemisphere-dependent: LAP-children showed longer latencies in the right than in the left hemisphere, whereas the distribution was reversed in the LAL and non-risk children. It was also found that the right hemisphere is generally responsible for a lion's share of the processing of figures and therefore it seems that the right hemisphere of LAP-children invests ample time in doing so. Whereas LAP-children showed largest SW amplitude differences between frequent and infrequent stimuli at posterior locations, LAL children did so at frontal locations. Assuming that the SW represents working-memory processes, it may be that working-memory in LAP-children deals with figure-relevant visual-spatial information and with figure-derived concepts in LAL children. Overall, the findings suggest that LAL and LAP represent two different groups of kindergartners at risk of dyslexia and that these differences, to some degree, fit with the presumed etiology of L- and P-type dyslexia.     

Retooling Education: Testing and the Liberal Arts

The motivation and methodology for measuring intelligence have changed repeatedly in the modern history of large-scale student testing. Test makers have always sought to identify raw aptitude for cultivation, but they have never figured out how to promote excellence while preserving equality. They’ve settled for egalitarianism, which gives rise to “culturally fair” tests that substitute vagaries for knowledge, deprive students of any real appreciation for language, and trivialize education. Robert Jackson yearns for traditional oratorical approaches to schooling that venerate and imitate essential, time-tested masters. Unfortunately, he writes, such an education defies measurement with today’s multiple-choice instruments.

非形式逻辑与演绎主义

非形式逻辑出现于上个世纪70年代,它首先是一种寻求更好的大学逻辑教学方式的努力.进而,非形式逻辑学者们逐渐开始触及和探讨越来越多的理论议题,即发展不依赖于形式逻辑的关于论证以及好论证的理解方式.在1998年世界哲学大会上,布莱尔和我阐释了非形式逻辑为哲学所带来的理论后果,其中一点我们称之为"演绎主义的终结".那时我们并未给出演绎主义的定义,而只是把它等同于麦金泰尔的那个精炼的说法:"任何推理,不是演绎的,就是有缺陷的."但现在看来,我们在当时就作出"演绎主义的终结"这一论断,显然是有点为时过早了.因为演绎主义似乎至今都还很有生命力,甚至在那些倾向于非形式逻辑的学者那里它也能得到支持:恩尼斯长期以来都辩护演绎主义是一种论证重构策略,格罗尔克更是致力于辩护它是一种论证评价理论.在本文中我将论证,非形式逻辑最好被理解为一种不诉诸于演绎技巧和演绎规范的逻辑研究.当我们意识到演绎和演绎主义已经如何深深地扎根于我们的哲学发展史中,并且牢牢地控制了我们关于逻辑研究的理解,我们就能明白非形式逻辑这一理论努力是多么的困难和重要.我将首先澄清"演绎主义"的意思,然后再分别考察那些赞成和反对演绎主义的论证,最后,我将表明非形式逻辑是从演绎主义中挽救逻辑的理论尝试.     

An Entity Theory of Intelligence Predicts Higher Cortisol Levels When High School Grades Are Declining

Grades often decline during the high school transition, creating stress. The present research integrates the biopsychosocial model of challenge and threat with the implicit theories model to understand who shows maladaptive stress responses. A diary study measured declines in grades in the first few months of high school: salivary cortisol (N = 360 students, N = 3,045 observations) and daily stress appraisals (N = 499 students, N = 3,854 observations). Students who reported an entity theory of intelligence (i.e., the belief that intelligence is fixed) showed higher cortisol when grades were declining. Moreover, daily academic stressors showed a different lingering effect on the next day's cortisol for those with different implicit theories. Findings support a process model through which beliefs affect biological stress responses during difficult adolescent transitions.

Trends and practices in functional behavior assessments completed by school psychologists

Functional Behavior Assessments (FBAs) utilize direct and indirect methods to collect data on student behavior to generate a functional hypothesis and drive intervention development. School psychologists are trained to conduct FBAs and use them regularly in schools. However, no evidence exists describing the specific practices used by school psychologists when they conduct FBAs. In this study, 199 respondents completed a web‐based survey developed using expert review and cognitive pretesting. Most respondents reported their gender as female (87%), were between 30 and 39 years old (50%), and practiced at the Specialist level (57%). Respondents reported receiving training in FBA across multiple sources and utilizing multi‐method data collection methods when conducting FBAs. A large amount of variability was observed in the specific instruments used by school psychologists, with a substantial proportion using forms that were not standardized or pre‐constructed. Implications for current practitioners, trainers, and researchers are described.     

Instructor Humor as a Moderator of Instructors’ Inappropriate Conversations and Instructional Dissent

This study (N?=?326) was conducted to examine the associations among instructor humor, inappropriate conversations, and instructional dissent. First, results showed students are more likely to employ rhetorical dissent when they perceive their instructors as humorous in the classroom. Second, using expectancy violations theory as a guide, results also indicated that students’ perceptions of instructor-relevant humor moderated the relationships between enactment of inappropriate conversations and students’ expressive and vengeful dissent. These findings support the importance of employing relevant humor in course instruction, especially when instructors engage in inappropriate conversations in the college classroom.
