Sensory impairments are widely reported in autism, but remain largely unexplained by existing models. This article examines Kanner's causal reasoning and identifies unsupported assumptions implicit in later empirical work. Our analysis supports a heterogeneous causal model for autistic characteristics. We propose that the development of a…

This study examined how the manifestation of overt aggression changes during early adolescence using Hierarchical Linear Modeling. The distinct courses of physical and verbal aggression identified in this study provide support for developmental transformations in overt aggression, which would have been obscured unless aggression had been defined…

This article uses simulation to compare two test equating methods under the common-item nonequivalent groups design: the frequency estimation method and the chained equipercentile method. An item response theory model is used to define the true equating criterion, simulate group differences, and generate response data. Three linear equating…

This study examined the student and high school contextual factors associated with high school students' enrollment in Hispanic-Serving Institutions (HSIs). The authors drew on a conceptual framework of college choice involving the concepts of multiple capitals and individual and organizational habitus to examine the postsecondary trajectories of…

While withdrawal from higher education may be the result of many reasons both within and beyond the control of the student or the institution, the intent of not returning to higher education indicates the acceptance of a permanent disassociation with the pursuit of the higher education endeavor. It is of paramount importance in understanding the…

Many studies of changes in learning approaches have used data from different age groups at one point in time only (Gow and Kember, High Educ 19:307-322, 1990; Watkins and Hattie, Br J Educ Psychol 51:384-393, 1981) or have analyzed the effects of just two or three factors using single level analytical techniques (Cano, Br J Educ Psychol…

In this theoretical essay, the author addresses the existence of divergent evidence, portraying both competence and lack of competence in a fundamental realm of higher order thinking--causal and scientific reasoning--and explores the educational implications. Evidence indicates that these higher order reasoning skills are not ones that can be…

Mental health disparities refer to the disproportionate amount of psychopathology found among persons of disadvantageous social standing, such as persons of low socioeconomic status (SES). Although social and self selection cannot entirely be ruled out as explanations for these differences, the accumulation of evidence supports a social causation…

The potential association between psychosis and violence to others has long been debated. Past research findings are mixed and appear to depend on numerous potential moderators. As such, the authors conducted a quantitative review (meta-analysis) of research on the association between psychosis and violence. A total of 885 effect sizes (odds…

Background: The connection between childhood violence exposure and antisocial behavior in adolescence has received much attention and has important implications for understanding and preventing criminal behavior. However, there are a limited number of well-designed prospective studies that can suggest a causal relationship, and little is known…

This study explored the relationship between ethnic identity, emotional empathy, multicultural sensitivity and dimensions of burnout among schoolteachers working with students from diverse ethnic groups. Based on the self-stereotyping principles and tendencies for ingroup favoritism of social identity approaches, it was hypothesized that…

In this article, the authors have 2 aims. First, hierarchical, nonhierarchical, and nonstandard log-linear models are defined. Second, application scenarios are presented for nonhierarchical and nonstandard models, with illustrations of where these scenarios can occur. Parameters can be interpreted in regard to their formal meaning and in regard…

We examined the effect of studying a causal diagram on comprehension of causal relationships from an expository science text. A causal diagram is a type of visual display that explicitly represents cause-effect relationships. In Experiment 1, readers between conditions did not differ with respect to memory for main ideas, but the readers who…

In this article we introduce a usage-goal framework within which task design can be guided and analyzed. We tell a tale of one task, the Pentomino Problem, and its evolution through predictive analysis, trial, reflective analysis, and adjustment. In describing several iterations of the task implementation, we focus on mathematical affordances…

When people make causal judgments from contingency information, a principal aim is to account for occurrences of the outcome. When 2 causes are under consideration, the capacity of either to account for occurrences is judged from how likely the cause is to be present when the outcome occurs and from the rate at which the outcome occurs when that…
