Parents' Explanations of Their Child's Performance in Mathematics and Reading: A Replication and Extension of Yee and Eccles

This study was conducted to examine whether Finnish parents would endorse the the classic gender-related attribution pattern and explain their son's mathematical performance in terms of talent and their daughter's in terms of effort. In addition, we examined whether the pattern of attributions would be the opposite in regard to parental explanations of their child's reading performance. A group of parents (N = 486), both mothers and fathers, were requested to assess the level of competence of their 1st grader in mathematics and reading. The parents were also asked to recall events from their child's 1st school year in which the child succeeded and failed in mathematics and reading; they were then asked to evaluate the importance of talent, effort, and task to the child's outcomes. The parents of boys assessed their child's mathematical competence to be higher than did the parents of girls. Furthermore, the parents of boys rated talent as a more important reason for their child's mathematical success than did the parents of girls. In contrast, the parents of girls rated effort as a more important reason for their child's mathematical success. Although the girls were perceived to surpass boys in reading, the girls' positive outcomes in reading were explained by effort more than the boys' outcomes, and at the highest level of assessed competence, the boys' verbal talent was rated as a more significant cause of success in reading than the girls' verbal talent. In sum, our results suggested that in both mathematics and reading, girls were not entitled to ability-based attribution to the same extent as were boys.     

On the capacity of attention: its estimation and its role in working memory and cognitive aptitudes

Working memory (WM) is the set of mental processes holding limited information in a temporarily accessible state in service of cognition. We provide a theoretical framework to understand the relation between WM and aptitude measures. The WM measures that have yielded high correlations with aptitudes include separate storage-and-processing task components, on the assumption that WM involves both storage and processing. We argue that the critical aspect of successful WM measures is that rehearsal and grouping processes are prevented, allowing a clearer estimate of how many separate chunks of information the focus of attention circumscribes at once. Storage-and-processing tasks correlate with aptitudes, according to this view, largely because the processing task prevents rehearsal and grouping of items to be recalled. In a developmental study, we document that several scope-of-attention measures that do not include a separate processing component, but nevertheless prevent efficient rehearsal or grouping, also correlate well with aptitudes and with storage-and-processing measures. So does digit span in children too young to rehearse.     

自由目标效应与样例效应对学生写作成绩影响

“自由目标效应”和“样例效应”是认知负荷理论为解决学习者的认知资源限制而提出的两个重要的教学设计原则。通过两个实验,研究“自由目标效应”和“样例效应”对不同写作水平学生写作成绩的影响。被试为406名初中一年级学生。结果表明,“自由目标效应”和“样例效应”受学生写作水平的影响。“自由目标效应”对高水平写作者有促进作用,但会降低低水平写作者的成绩;“样例效应”对低水平写作者有促进作用,但对高水平写作者的写作成绩无显著影响。     

大学生人格特质、社会适应能力与网络成瘾倾向的关系

运用问卷调查法探讨了人格特质、社会适应能力和网络成瘾倾向的关系。对211位大学生(男120人,女91人)的调查结果表明:(1)精神质和社会适应能力对大学生网络成瘾倾向有直接影响;(2)精神质还通过社会适应能力间接影响网络成瘾倾向。     

作文中借助书语优势进行口语表达策略的研究

本研究采用自然实验与实验室实验结合的方法,探讨作文中借助书语优势进行口语表达的策略及机制。结果表明,运用笔述后口述策略借助书语优势没有总体意义上的效果．但能够显著提高高水平学生与说劣写优水平学生的口述质量。这一研究可以解释作文教学中多用口述后笔述而少用笔述后口述的原因。同时指出,对于那些写作水平较高但由于某种原因口头表达较差的学生,可以运用笔述后口述的策略,借助其自身较强的笔述优势改善并提高口述质量。     

Instructor Feedback for College Writing Assignments in Introductory Classes

We compared three instructor feedback protocols to determine whether minimal instructor feedback could improve undergraduate students' writing skills in large introductory classes. The three feedback conditions were specific feedback, nonspecific feedback, and grade only. Sixty community college students participated in the study. Sections of an Introduction to Human Services course were randomly assigned to the three feedback conditions. Students wrote 9 timed essays during the semester. Pretest data were collected from the first essay at the beginning of the semester. Posttest data were taken from the final essay. Data for each student's essays consisted of the number of words written, the number of spelling errors, and the number of syntax grammar errors. Between the pretest and the posttest, students wrote 7 timed essays during class periods. Students in the specific feedback condition received a tally of spelling and grammar errors on grade criteria sheets and the location of the errors marked on their essays. In the nonspecific feedback condition, students received a tally of the errors on their grade criteria sheets but the locations of the errors were not marked on the essays. In the grade only condition, students received feedback on the number of points they had earned for each essay. Significant differences were found for pretest–posttest difference (gain) scores for the proportion of errors to the number of words written between the specific feedback condition and the grade only condition. Specific feedback decreased the proportion of errors to words written. The grade only condition maintained the same proportion of errors to words written from pretest to posttest. Significant differences were also found between difference (gain) scores for total errors between the specific feedback condition and the grade only condition and between the nonspecific feedback condition and the grade only condition.     

Flexible spatial mapping of different notations of numbers in Chinese readers

The spatial component of numerical and ordinal information has been explored in previous research. However, how such mapping emerges and how it is affected by the learning experience are issues still under debate. In the current study, we examined the orientation of the mental number line for different numerical notations (e.g., “1”, “—-”, “”) in Chinese readers. Our data demonstrated that Arabic numbers are mentally aligned horizontally with a left-to-right directionality, while Chinese number words are aligned vertically with a top-to-bottom directionality. These findings indicate that different notations of the same concept have flexible mappings within space, which is plausibly shaped by the dominant context in which the numerical notations appear.     

Genetic and environmental influences on the Verbal-Perceptual-Image Rotation (VPR) model of the structure of mental abilities in the Minnesota study of twins reared apart

In previous papers [Johnson, W., & Bouchard Jr., T. J. (2005a). Constructive Replication of the Visual-Perceptual-Image Rotation (VPR) Model in Thurstone's (1941) Battery of 60 Tests of Mental Ability. Intelligence, 33, 417–430.] [Johnson, W., & Bouchard Jr., T. J. (2005b). The Structure of Human Intelligence: It's Verbal, perceptual, and image rotation (VPR), not Fluid and Crystallized. Intelligence, 33, 393–416.] we have proposed the Verbal, perceptual, and image rotation (VPR) model of the structure of mental abilities. The VPR model is hierarchical, with a g factor that contributes strongly to broad verbal, perceptual, and image rotation abilities, which in turn contribute to 8 more specialized abilities. The verbal and perceptual abilities, though separable, are highly correlated, as are the perceptual and mental rotation abilities. The verbal and mental rotation abilities are much less correlated. In this study we used the twin sample in the Minnesota Study of Twins Reared Apart to estimate the genetic and environmental influences and the correlations among them at each order of the VPR model. Genetic influences accounted for 67–79% of the variance throughout the model, with the exception of the second-stratum Content Memory factor, which showed 33% genetic influence. These influences could not be attributed to assessed similarity of rearing environment. Genetic correlations closely mirrored the phenotypic correlations. Together, these findings substantiate the theory that the entire structure of mental abilities is strongly influenced by genes.
