This study aimed to investigate to what extent reading and spelling share cognitive processes at different phases of literacy acquisition. The contributions of phonological awareness, letter-sound matching skills, and rapid naming (RAN) to spelling and reading were measured in a large sample with Dutch children (N?=?1,284) covering all primary school grades. The results indicated a different developmental pattern for spelling than for reading. At initial phases of literacy acquisition, phonological awareness and letter-sound matching skills contributed to both reading and spelling performance. However, in contrast to the declining influence of phonological awareness and letter-sound matching skills on fluent word reading (see also Vaessen & Blomert, 2010 Vaessen, A. and Blomert, L. 2010. Long term cognitive dynamics of fluent reading development. Journal of Experimental Child Psychology, 105: 213231. doi:10.1016/j.jecp.2009.11.005[Crossref], [PubMed], [Web of Science ®] [Google Scholar]), the contributions of these skills to spelling performance were stable over the years, suggesting an ongoing reliance on orthography/phonology mappings during spelling. RAN did not contribute to spelling performance in any of the grades, in contrast to its strong contribution to reading performance, suggesting that RAN captures a cognitive skill that is unique for reading acquisition.  相似文献

Social-psychological research conducted over the past 15 years provides compelling evidence that pervasive psychological threats are present in common academic environments—especially threats that originate in negative intellectual stereotypes—and that these threats undermine the real-world academic performance of non-Asian ethnic minority students and of women in math and science. As a consequence, common measures of academic performance, including both grades and test scores, systematically underestimate the intellectual ability of ethnic minority students and of women in quantitative fields (Walton & Spencer, 2009 Walton, G. M. and Spencer, S. J. 2009. Latent ability: Grades and test scores systematically underestimate the intellectual ability of negatively stereotyped students. Psychological Science,, 20,: 11321139. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]). We review evidence for these psychological threats, discuss their implications for the meaning and interpretation of common performance measures used in important admissions decisions, and address their implications for the efforts of colleges and universities to create positive academic environments that allow all students to thrive.  相似文献

Human beings have a fundamental need to belong, for ongoing positive interactions with others who provide companionship and caring (Baumeister & Leary, 1995 Baumeister, R. F., & Leary, M. R. (1995). The need to belong: Desire for interpersonal attachments as a fundamental human motivation. Psychological Bulletin, 117, 497529. doi: 10.1037/0033-2909.117.3.497.[Crossref], [PubMed], [Web of Science ®] [Google Scholar]). Children may hit, exclude, or harass others electronically because when their own needs for belongingness are threatened, or when they want to enhance their own status, they lash out and hurt others in the way they think will be most painful, by engaging in behaviors that undermine the target's sense of belongingness. For reasons discussed herein, children and adolescents might be especially vulnerable to desperate needs for belongingness. Viewing bullying as motivated by the need to belong has profound implications for prevention and intervention programs to reduce bullying.  相似文献

Andrew Elby (this issue) argues that researchers in the field of personal epistemology should beware insistence on a narrow definition of epistemology to guide this work. His argument is a response to suggestions (Hofer & Pintrich, 1997 Hofer, B. K. and Pintrich, P. R. 1997. The development of epistemological theories: Beliefs about knowledge and knowing and their relation to learning.. Review of Educational Research, 67(1): 88140. [Crossref], [Web of Science ®] [Google Scholar]; Sandoval, 2005 Sandoval, W. A. 2005. Understanding students' practical epistemologies and their influence on learning through inquiry.. Science Education, 89: 634656. [Crossref], [Web of Science ®] [Google Scholar]) that the study of personal epistemology should focus on people's views about knowledge and knowing and not conflate those with views about learning. His main concern is that learners' views about knowledge and their views about learning may, in fact, be conflated and that an insistence on definitional clarity could lead to a mischaracterization of cognitive structures. In this response I argue that clarity in the definition of theoretical constructs does not imply exclusion of views about learning from the study of personal epistemology. Furthermore, given the history of this area of research, failing to more clearly define our constructs makes real theoretical progress difficult.  相似文献

Recent findings (Keysar, 1994 Keysar, B. 1994. The illusory transparency of intention: Linguistic perspective taking in text.. Cognitive Psychology, 26: 165208. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]; Weingartner & Klin, 2005 Weingartner, K. M. and Klin, C. M. 2005. Perspective taking during reading: An on-line investigation of the illusory transparency of intention.. Memory & Cognition, 33: 4858. [Crossref] [Google Scholar]) have shown that readers are not always accurate at taking a story character's perspective. When readers evaluated a character's understanding of a written message, they mistakenly took into account information that was inaccessible to that character. The results from the three experiments reported here demonstrate that this “illusory transparency of intention” is not dependent on the message readers' communicative role: Even when the message was composed for one character but read by another, readers assumed that the message was understood as it was intended. The results are discussed in the context of two theoretical accounts for these perspective-taking errors: the “knowledge projection hypothesis,” which appeals to readers’ expectations about cooperative behavior during communication, and “construal,” which attributes the illusory transparency of intention to a general cognitive bias that occurs during the perception of ambiguous stimuli.  相似文献

Relevant aspects of the example provided by Raykov and Marcoulides (2001) Raykov, T. and Marcoulides, G. A. 2001. Can there be infinitely many models equivalent to a given covariance structure model?. Structural Equation Modeling, 8: 142149. [Taylor & Francis Online], [Web of Science ®] [Google Scholar] are emphasized, specifically the distinctiveness of infinitely many members of its sequence of equivalent structural equation models. This emphasis appears to be needed in light of recent statements by Markus (2002) Markus, K. A. 2002. Statistical equivalence, semantic equivalence, eliminative induction and the Raykov–Marcoulides proof of infinite equivalence. Structural Equation Modeling, 9: 503522. [Taylor & Francis Online], [Web of Science ®] [Google Scholar], whose intended counterexamples do not present a disconfirmation of any of the developments of Raykov and Marcoulides (2001) Raykov, T. and Marcoulides, G. A. 2001. Can there be infinitely many models equivalent to a given covariance structure model?. Structural Equation Modeling, 8: 142149. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]. Issues pertaining to differentiation between equivalent models are also discussed.  相似文献

This study used statistical simulation to calculate differential statistical power in dynamic structural equation models with groups (as in McArdle & Prindle, 2008 McArdle, J. J. and Prindle, J. J. 2008. A latent change score analysis of a randomized clinical trial in reasoning training. Psychology and Aging, 23: 702719. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]). Patterns of between-group differences were simulated to provide insight into how model parameters influence power approximations. Chi-square and root mean square error of approximation (RMSEA) power approximation procedures were used to compare the effects of parameter manipulations and how researchers should interpret findings. The chi-square power of perfect fit calls for at least 270 individuals to detect moderate differences, whereas the RMSEA procedure of close fit seems to require as many as 1,450 participants. It is shown that parameters that provide input into the change score that the transfer leads to affect power versus indirect pathways. A discussion of differences in approximation values and future research directions follows.  相似文献

The objective of this study was to evaluate the reliability and validity of the Hebrew version of Kogan's (1961 Kogan , N. ( 1961 ). Attitudes Toward Old People: The development of a scale and an examination of correlates . Journal of Abnormal and Social Psychology , 62 ( 1 ), 4454 . doi: 10.1037/h0048053 [Crossref], [PubMed], [Web of Science ®] [Google Scholar]) Attitudes Toward Old People scale. A self-administered questionnaire in Hebrew was given to a convenience sample of 300 people under the age of 65 who resided in three neighborhoods in Tel Aviv. The Hebrew version of the Attitudes toward Old People scale demonstrated good psychometric properties. Internal consistency of Cronbach's alpha was high (α = .89). Factor analysis showed five loading factors. The Israeli version of the scale was found to be a valid and reliable instrument for measuring the general population's attitudes toward older people. It can be a useful instrument for studies in Israel as well as for cross-national and comparative studies to assess the degree of ageism towards older people.  相似文献

There is limited research demonstrating direct instruction (DI) as an effective language intervention for students with autism spectrum disorders (ASD) and developmental disabilities (DD). Existing research has shown that instruction using partial implementation of DI programs resulted in student learning (Ganz, 2007 Ganz, M. L. (2007). The lifetime distribution of the incremental societal costs of autism. Archives of Pediatrics & Adolescent Medicine, 161, 343&349.[Crossref], [PubMed], [Web of Science ®] [Google Scholar]) and instruction using whole lessons resulted in positive instructional effects for students with ASD and DD (Ganz, 2007 Ganz, M. L. (2007). The lifetime distribution of the incremental societal costs of autism. Archives of Pediatrics & Adolescent Medicine, 161, 343&349.[Crossref], [PubMed], [Web of Science ®] [Google Scholar]). However, it is not known whether DI is more effective than other language interventions. The purpose of this study was to compare DI to an established intervention, discrete trial teaching. Thirteen students with ASD or participated in the study and data were collected using curriculum-based assessment. An independent samples t-test indicated that there was a statistically significant difference in student performance for the group who received DI. Results and their implications will be discussed.  相似文献

The purpose of this study was to examine persistence in school among students with Foetal Alcohol Spectrum Disorder (FASD) from the perspectives of the students themselves and their parents. Tinto’s (1975 Tinto, V. 1975. Dropout from higher education: a theoretical synthesis of recent research. Review of Educational Research, 45(1): 89125. [Crossref], [Web of Science ®] [Google Scholar], 1997 Tinto, V. 1997. Classrooms as communities: exploring the educational character of student persistence. Journal of Higher Education, 68(6): 599623. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]) Student Integration Model (SIM) provided the theoretical framework for this research. This model involves an interplay between (1) background characteristics and attributes affecting the level of goal commitment, (2) level of academic integration, and (3) level of social integration into the institution that determine whether or not a student will graduate. The findings showed limited support for Tinto’s SIM and that parental advocacy is strongly linked with persistence among adolescents with FASD. A new model showing the parents’ role in encouraging persistence through their actions at home and advocacy at the schools is presented.  相似文献

We highlight critical conceptual and statistical issues and how to resolve them in conducting Satorra–Bentler (SB) scaled difference chi-square tests. Concerning the original (Satorra & Bentler, 2001 Satorra, A. and Bentler, P. M. 2001. A scaled difference chi-square test statistic for moment structure analysis. Psychometrika, 66: 507514. [Crossref], [Web of Science ®] [Google Scholar]) and new (Satorra & Bentler, 2010 Satorra, A. and Bentler, P. M. 2010. Ensuring positiveness of the scaled chi-square test statistic. Psychometrika, 75: 243248. [Crossref], [Web of Science ®] [Google Scholar]) scaled difference tests, a fundamental difference exists in how to compute properly a model's scaling correction factor (c), depending on the particular structural equation modeling software used. Because of how LISREL 8 defines the SB scaled chi-square, LISREL users should compute c for each model by dividing the model's normal theory weighted least-squares (NTWLS) chi-square by its SB chi-square, to recover c accurately with both tests. EQS and Mplus users, in contrast, should divide the model's maximum likelihood (ML) chi-square by its SB chi-square to recover c. Because ML estimation does not minimize the NTWLS chi-square, however, it can produce a negative difference in nested NTWLS chi-square values. Thus, we recommend the standard practice of testing the scaled difference in ML chi-square values for models M 1 and M 0 (after properly recovering c for each model), to avoid an inadmissible test numerator. We illustrate the difference in computations across software programs for the original and new scaled tests and provide LISREL, EQS, and Mplus syntax in both single- and multiple-group form for specifying the model M 10 that is involved in the new test.  相似文献

This mixed-methods study develops, operationalizes, and tests a new conceptual model of community college student engagement. Themes emerging from participant observations and semistructured interviews with 30 adult students enrolled at a Large Best Practices Community College (LBPCC) over the 2005–2006 academic year are used to guide selection of Self-Determination Theory (Deci & Ryan, 1985 Deci , E. L. & Ryan , R. M. ( 1985 ). Intrinsic motivation and self-direction behavior . New York : Plenum .[Crossref] [Google Scholar], 2000 Deci , E. L. & Ryan , R. M. ( 2000 ). Intrinsic and extrinsic motivations: Classic definitions and new directions . Contemporary Educational Psychology , 25 , 5467 .[Crossref], [PubMed], [Web of Science ®] [Google Scholar], 2002 Deci , E. L. & Ryan , R. M. ( 2002 ). Handbook of self-determination research . Rochester , NY : University of Rochester . [Google Scholar]) to frame the new conceptual model. Structural equation modeling techniques confirm that variables and relationships proposed by the new model represent a good fit with data from over 1,000 students surveyed in the Community College Survey of Student Engagement. Findings from this study suggest that community college engagement and related outcomes can be fostered by tuning campus policies, practices, and climates to promote students' senses of belonging, competence, and autonomy.  相似文献

The purpose of this study was to examine relationships among memory aging knowledge and memory self-appraisal in college students and community-dwelling older adults. Participants completed the Knowledge of Memory Aging Questionnaire ([KMAQ] Cherry, Brigman, Hawley, & Reese, 2003 Cherry , K. E. , Brigman , S. , Hawley , K. S. , & Reese , C. M. ( 2003 ). The knowledge of memory aging questionnaire: Effects of adding a ‘don't know’ response option . Educational Gerontology , 29 , 427446 . doi: 10.1080/713844360 [Taylor & Francis Online], [Web of Science ®] [Google Scholar]) and the Memory Functioning Questionnaire ([MFQ] Gilewski, Zelinski, & Schaie, 1990 Gilewski , M. J. , Zelinski , E. M. , & Schaie , K. ( 1990 ). The memory functioning questionnaire for assessment of memory complaints in adulthood and old age . Psychology and Aging , 5 , 482490 . doi: 10.1037/0882-7974.5.4.482 [Crossref], [PubMed], [Web of Science ®] [Google Scholar]). We hypothesized that poorer performance on the KMAQ stereotype scale, suggesting an ageist response bias, would be associated with more negative self-appraisals of memory. Results confirmed that responses on the KMAQ stereotype scale were significantly associated with responses on the MFQ Frequency of Forgetting scale and two shorter scales derived from the full MFQ, the memory self-efficacy scale (Zelinski & Gilewski, 2004 Zelinski , E. M. , & Gilewski , M. J. ( 2004 ). A 10-item Rasch modeled memory self-efficacy scale . Aging & Mental Health , 8 , 293306 . doi: 10.1080/13607860410001709665 [Taylor & Francis Online], [Web of Science ®] [Google Scholar]), and a revised Seriousness of Forgetting scale after controlling for age and educational level. Implications of these findings for the development of instructional materials to improve memory aging knowledge and memory self-appraisal in adulthood are discussed.  相似文献

The significant increase in the numbers of students with autism combined with the need for better trained teachers (National Research Council, 2001) call for research on the effectiveness of alternative methods, such as consultation, that have the potential to improve service delivery. Data from 2 randomized controlled single-blind trials indicate that an autism-specific consultation planning framework known as the collaborative model for promoting competence and success (COMPASS) is effective in increasing child Individual Education Programs (IEP) outcomes (Ruble, Dalrymple, & McGrew, 2010 Ruble, L. A., Dalrymple, N. J. and McGrew, J. H. 2010. The effects of consultation on Individualized Education Program outcomes for young children with autism: The collaborative model for promoting competence and success. Journal of Early Intervention, 32: 286301. doi:10.1177/1053815110382973[Crossref], [PubMed] [Google Scholar]; Ruble, McGrew, & Toland, 2011 Ruble, L., McGrew, J. and Toland, M. Randomized controlled study of teacher training in autism. Poster session presented at the meeting of the American Psychological Association. Washington, DC. August.  [Google Scholar]). In this study, we describe the verbal interactions, defined as speech acts and speech act exchanges that take place during COMPASS consultation, and examine the associations between speech exchanges and child outcomes. We applied the Psychosocial Processes Coding Scheme (Leaper, 1991 Leaper, C. 1991. Influence and involvement in children's discourse: Age, gender, and partner effects. Child Development, 62: 797811. doi:10.1111/j.1467-8624.1991.tb01570.x[Crossref], [PubMed], [Web of Science ®] [Google Scholar]) to code speech acts. Speech act exchanges were overwhelmingly affiliative, failed to show statistically significant relationships with child IEP outcomes and teacher adherence, but did correlate positively with IEP quality.  相似文献

A motor task that requires fine control of upper limb movements and a cognitive task that requires executive processing—first performing them separately and then concurrently—was performed by 18 young and 18 older adults. The motor task required participants to tap alternatively on two targets, the sizes of which varied systematically. The cognitive task required participants to generate a series of random numbers at fixed production rates. Participants' performance on the motor task decreased slightly from single- to concurrent-task condition, and the dual-task cost was age-independent. Older adults showed large cognitive dual-task costs as motor-control demands increased. Younger adults' cognitive performance was not affected by concurrent task demands. These results are discussed in light of the permeation model developed by Baltes and Lindenberger (1997 Baltes , P. B. & Lindenberger , U. ( 1997 ). Emergence of a powerful connection between sensory and cognitive functions across the adult life span: A new window to the study of cognitive aging? Psychology and Aging , 12 ( 1 ), 1221 .

Yuan and Hayashi (2010) Yuan, K.-H. and Hayashi, K. 2010. Fitting data to model: Structural equation modeling diagnosis using two scatter plots. Psychological Methods, 15: 335351. [Crossref], [Web of Science ®] [Google Scholar] introduced 2 scatter plots for model and data diagnostics in structural equation modeling (SEM). However, the generation of the plots requires in-depth understanding of their underlying technical details. This article develops and introduces an R package semdiag for easily drawing the 2 plots. With a model specified in EQS syntax, one only needs to supply as few as 2 parameters to generate the 2 plots using the semdiag package. Two examples are provided to illustrate the use of the package. Multiple figures are used to explain the elements of data and model diagnostics. Advice on selecting proper estimation methods following the diagnostics is also given.  相似文献

In structural equation modeling, Monte Carlo simulations have been used increasingly over the last two decades, as an inventory from the journal Structural Equation Modeling illustrates. Reaching out to a broad audience, this article provides guidelines for reporting Monte Carlo studies in that field. The framework of discourse is set by a number of steps to be taken in such research, matching outlines of experimental design by Paxton, Curran, Bollen, Kirby, and Chen (2001) Chen, F., Bollen, K. A., Paxton, P., Curran, P. J. and Kirby, J. 2001. Improper solutions in structural equation modeling: Causes, consequences, and strategies. Sociological Methods & Research, 29: 468508. [Crossref], [Web of Science ®] [Google Scholar] and Skrondal (2000) Skrondal, A. 2000. Design and analysis of Monte Carlo experiments: Attacking the conventional wisdom. Multivariate Behavioral Research, 35: 137167. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]. Throughout the article, reference is made to exemplary publications and, occasionally, to imperfect reporting.  相似文献

The purpose of this study was to assess the effectiveness of a short intervention program designed to enhance the educators' ability to identify children with developmental coordination disorder (DCD). Twenty early childhood and 20 physical education teachers (n = 40) participated in the study. Participants were randomly assigned into an experimental group (n = 20) and a control group (n = 20). A 3-week intervention program implemented, which comprised of four 2-hour lectures and two practice sections of the same duration and focused on the issue of DCD within the educational setting. After the completion of the program, each educator evaluated four children's motor performance using the Movement Assessment Battery for Children Checklist (Sugden & Sugden, 1991 Sugden, D. A. and Sugden, L. 1991. The assessment of movement skill problems in 7- and 9-year-old children. British Journal of Educational Psychology, 61: 329345. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]). Subsequently, another assessment took place using the Movement Assessment Battery for Children. The total number of evaluated children was 160. Results showed that the educators who attended the educational program showed higher identification ability. No significant differences were found between physical education and early childhood teachers of the experimental group. On the contrary, in the control group, early childhood teachers exhibited higher identification ability than the physical education teachers. The intervention program significantly enhanced the educators' ability to identify children with DCD. The implication of this study is that the education of school professionals should be a continuous process.  相似文献

Bandura's Social Learning Theory purports that early exposure to this social information may have an impact on children's schema development (e.g., Bandura, 2001 Bandura , A. ( 2001 ). Social cognitive theory: An agentic perspective . Annual Review of Psychology , 52 , 126 .[Crossref], [PubMed], [Web of Science ®] [Google Scholar]), which may influence how children and later adults think about what it means to age and get older (e.g., what it means to be an aging woman in society). By extension, if the portrayal of aging women characters in picture books contains both ageist and sexist attitudes, then the concern is that learned double jeopardy social schemas may influence both children's and the broader society's reactions to this aging sub-population (Chappell & Havens, 1980 Chappell , N. L. , & Havens , B. ( 1980 ). Old and women: Testing the double jeopardy hypothesis . The Sociological Quarterly , 21 ( 2 ), 157171 .[Crossref], [Web of Science ®] [Google Scholar]) and personal self-efficacy toward aging (Bandura, 2011 Bandura , A. ( 2011 , September). On the functional properties of perceived self-efficacy revisited. Journal of Management pp. 1–37. doi:10.1177/0149206311410606  [Google Scholar]). For the purpose of the current research, a possible double jeopardy portrayal was examined for older women characters in children's picture books. Using a stratified random sampling of 90 children's picture books, results found that older book characters were depicted in only about one-third of the sampled books, and older women portrayals were generally more negative (e.g., “hag”). The current study analyzed the biased aging portrayals in children's picture books, and found evidence for double jeopardy (e.g., both ageist and sexist attitudes combined) in how aging women characters were presented in both text and imagery. Implications toward future research and education interventions that convey more positive messages about aging and being a woman aging in society will be discussed.  相似文献
