Based on previous neuroscientific evidence indicating activation of the mirror neuron system in response to dynamic facial actions, we hypothesized that facial mimicry would occur while subjects viewed dynamic facial expressions. To test this hypothesis, dynamic/static facial expressions of anger/happiness were presented using computer-morphing…

Although structural equation modeling (SEM) is one of the most comprehensive and flexible approaches to data analysis currently available, it is nonetheless prone to researcher misuse and misconceptions. This article offers a brief overview of the unique capabilities of SEM and discusses common sources of user error in drawing conclusions from…

Previous studies have reported working memory deficits in autism, but this finding has been inconsistent. One possibility is that deficits in this domain may be present only when working memory load exceeds some limited capacity. High-functioning individuals with autism performed the CANTAB computerized test of spatial working memory. Individuals…

Computer algebra systems (CASs) have been used by thousands of teachers and students for teaching and learning algebra. They have the ability to perform efficiently almost all of the algebraic expansions and simplifications. Nevertheless, the traditional approach of using paper and pencil in acquiring procedural knowledge is still widely…

We examined rates of HIV testing of persons with disabilities relative to HIV testing rates of people without disabilities in the United States. Using data from the 2002 NHIS we examined the association between self-reported disability and having ever been tested for HIV. Adults with disability were more likely than nondisabled adults to report…

Just about everyone suspects that the rush to enrol distance-learning students in on-campus degrees tends to disadvantage them. Monir Mir and Abu Shiraz Rahaman set out to test this intuition, using accounting students as their guinea-pigs. (Contains 6 figures and 5 tables.)

Two eye-tracking studies assessed effects of grammatical and conceptual gender cues in generic role name processing in German. Participants read passages about a social or occupational group introduced by way of a generic role name(e.g., "Soldaten"/soldiers, "Kunstler"/artists). Later in the passage the gender of this group was specified by the…

Background: Activity level is an important component of children's temperament, as well as being part of the core symptom domain of hyperactivity-impulsivity within attention deficit hyperactivity disorder (ADHD). Yet it is poorly understood, due partly to limitations on parent and teacher ratings, which are typically used as measurements of these…

Educational accommodations for students with vision impairments are alterations in the way that an assessment or a test is administered. These alterations are not made to give the student an advantage, but to level the playing field with sighted peers. The authors provide for the educational practitioner a taxonomy of these types of accommodation…

Based on common aspects of recent models of career decision making (CDM), a six-phase model of CDM for secondary students is presented and empirically evaluated. The study tests the hypothesis that students who are in later phases possess more career-choice readiness and consider different numbers of career alternatives. Two hundred sixty-six…

This study assesses the adequacy of item gradients and ceilings for the subtests of the Woodcock-Johnson III (WJ III) Cognitive and Achievement batteries, including the Diagnostic Supplement, in their use with participants ages 16 to 25 and Grades 10 to 18. Of the 52 subtests, 18 contain adequate item gradients and ceilings for the entire age and…

In response to Lissitz and Samuelsen (2007), the author reconstructs the historical arguments for the more comprehensive unitary concept of validity and the principles of scientific inquiry underlying it. Her response is organized in terms of four questions: (a) How did validity in educational measurement come to be conceptualized as unitary, and…

Research protocols involving children often include psychological testing as part of an assessment battery. Inclusion of such testing raises the question of whether parents (or others) should be offered the individualized results of their children's psychological testing conducted for research purposes. The purpose of this article is to provide a…

J. Brooks-Gunn, W. J. Han, and J. Waldfogel (2002) and the National Institute of Child Health and Human Development Early Child Care Research Network (ECCRN; 2000b) came to different conclusions about the effects of maternal employment--although they were addressing similar questions using the same data set. Brooks-Gunn et al. concluded that…

There's accountability and then there's the testing craze an iatrogenic practice that undermines real learning. Hedrick documents the negative effects of testing, giving teachers another weapon in their arsenal against mindless preparation for high-stakes tests.
