The linguistic properties of the first (critical) character of a two-character Chinese word were manipulated when the eyes moved to the right of the critical character during reading to determine whether character processing is strictly unidirectional. In Experiment 1, the critical character was replaced with a congruent or incongruent character…

There has been considerable interest in nonlinear latent variable models specifying interaction between latent variables. Although it seems to be only slightly more complex than linear regression without the interaction, the model that includes a product of latent variables cannot be estimated by maximum likelihood assuming normality.…

The Mantel-Haenszel (MH) and logistic regression (LR) differential item functioning (DIF) procedures have inflated Type I error rates when there are large mean group differences, short tests, and large sample sizes.When there are large group differences in mean score, groups matched on the observed number-correct score differ on true score,…

Hybrid treatment models within prisons are staffed by both criminal justice and treatment professionals. Because these models may be indicative of future trends, examining the perceptions of prisoners/participants may provide important information. This study examines the perceptions of male and female inmates in three prisons, comparing those in…

This study evaluates the concurrent validity of an on-line Yes/No test of recognition vocabulary as a placement tool at an Australian English language school. Newly entering students (n = 88) completed a Yes/No test, which measured accuracy and speed of response, and a school placement battery consisting of grammar, writing, speaking and listening…

Objective: The purpose of this study was to apply Ajzen's theory of planned behavior (TPB) and a measure of past physical activity behavior to predict first-year students' physical activity intentions and behavior. Participants and Methods: First-year university students (N = 212) completed measures of TPB variables and past physical activity at…

Objective: This study explored whether specific dimensions of spiritual well-being (religious well-being and existential well-being) relate to reduced suicidal ideation, and whether associations persisted after controlling for religiosity and psychosocial variables associated with suicide. Participants: Participants were 457 college students who…

This methodological note illustrates how a commonly used calculation of the Delta-p statistic is inappropriate for categorical independent variables, and this note provides users of logistic regression with a revised calculation of the Delta-p statistic that is more meaningful when studying the differences in the predicted probability of an…

To understand the conditions that give rise to parenting self-efficacy in Japan and the United States, the authors have investigated its relation to the perceptions of support available to mothers of children in the final year of preschool (N = 235; n = 121 in United States, n = 114 in Japan). Hierarchical regression analysis indicates that in…

This article examines the use of clinicians' ratings of batterer program participants to predict their reassaults during a 6-month posttreatment follow-up and a longer and more inclusive postintake follow-up period (n = 380). The ratings consist of 10 items that reflect the behavioral criteria used by clinicians in making judgment about treatment…

We explain how to simulate both univariate and bivariate raw data sets having specified values for common summary statistics. The first example illustrates how to "construct" a data set having prescribed values for the mean and the standard deviation--for a one-sample t test with a specified outcome. The second shows how to create a bivariate data…

Part-time faculty clearly serve a valuable purpose in higher education; however, their increased use raises concerns for administrators, faculty, and policy makers. Part-time faculty members spend a greater proportion of their overall time teaching, but the initial evidence suggests that these instructors are less available to students and are…

In three large samples (N = 1248) of children learning to read German we investigated the correlations between rapid automatized naming (RAN), phonological awareness (PA), phonological decoding (nonword reading fluency), and orthographic processing (word reading fluency and spelling). In a series of hierarchical regression analyses, RAN explained…

This study focused on individual differences in maternal style and children's developing recall abilities in early memory conversations. Within a longitudinal design, a sample of 56 mother-child dyads was observed while reminiscing, and the children's language skills were assessed when they were 18, 24, and 30 months old. In contrast to mothers…

The current study examined the associations among trait dimensions of perfectionism, test performance, and levels of positive and negative affect after taking a test. A sample of 92 female university students completed the Multidimensional Perfectionism Scale one week prior to an actual class test. Measures of positive affect and negative affect…
