Previous work on the long-term effects of early reading focuses on whether children can read early (i.e. capability) not on whether this is beneficial (i.e. optimality). The Luke Effect is introduced to predict long-term reading development as a function of when children learn to read. A review of correlational, intervention, and comparative…

The main aim of this paper is to develop an amalgamated conceptual model of technology acceptance that explains how individual, social, cultural and organizational factors affect the students' acceptance and usage behaviour of the Web-based learning systems. More specifically, the proposed model extends the Technology Acceptance Model (TAM) to…

Forgiveness has received widespread attention among psychologists from social, personality, clinical, developmental, and organizational perspectives alike. Despite great progress, the forgiveness literature has witnessed few attempts at empirical integration. Toward this end, we meta-analyze results from 175 studies and 26,006 participants to…

In the United States, racial-ethnic differences on tests of school readiness and academic achievement continue. A complete understanding of the origins of racial-ethnic achievement gaps is still lacking. This article describes social equity theory (SET), which proposes that racial-ethnic achievement gaps originate from two kinds of social process,…

The authors of this article test hypotheses derived from Irwin's rabble management thesis. The analysis uses data from 47,592 interviews conducted with jailed adults in 30 U.S. cities as part of the Arrestee Drug Abuse Monitoring program. Clearly, homeless persons are overrepresented among those arrested and booked into local jails. Bivariate…

An experiment compared asynchronous versus synchronous instruction in an online quantitative course. Mann-Whitney U-tests, correlation, analysis of variance, t tests, and multivariate analysis of covariance (MANCOVA) were utilized to test the hypothesis that more high-quality online experiential learning interactions would increase grade.…

This study compares perceptions of domestic violence for college students planning to work in law enforcement with students aspiring to careers in social work and non-law-enforcement criminal justice (N = 491). The study involves students attending four public universities across one Southern state who completed a survey (spring of 2006) measuring…

As the transition to adulthood becomes more protracted and less orderly, fewer young people occupy adult roles and experience the social control associated with these roles. One might therefore expect behaviors associated with the teenage years to spill over into older age groups, reflecting postponed entrance into full social adulthood. We test…

Objective: The present article tests the hypothesis of a sustained attention deficit in children and adults suffering from ADHD. Method: Vigilance and sustained attention of 52 children with ADHD and 38 adults with ADHD were assessed using a computerized vigilance task. Furthermore, the attentional performance of healthy children (N = 52) and…

The authors tested hypotheses concerning personality differences in treatment-seeking suicide attempters (AT; n = 60) and a community sample of suicides (SU; n = 43) over age 50. On the basis of prior research, the authors hypothesized that SU would be lower in Neuroticism and Openness and higher in Conscientiousness. A 2-group (AT vs. SU)…

Kohlberg's (1966) hypothesis that the attainment of gender constancy motivates children to attend to gender norms was reevaluated by examining these links in relation to age. Ninety-four 3- to 7-year-old children were interviewed to assess whether and how constancy mediates age-related changes in gender-related beliefs. As expected, results…

General normal ogive and logistic multiple-group models for paired comparisons data are described. In these models, scale value and discriminal dispersion parameters are allowed to vary across stimuli and respondent populations. Model fitting and hypothesis testing are illustrated using health care coverage data from two age groups. (SLD)

The counterintuitive developmental trend in the Deese-Roediger-McDermott (DRM) illusion (that false-memory responses increase with age) was investigated in learning-disabled and nondisabled children from the 6- to 14-year-old age range. Fuzzy-trace theory predicts that because there are qualitative differences in how younger versus older children…

E-learning is significant breakthrough in teaching and learning. Internet or web technologies are important because they facilitate and enhance communications among instructors and learners and provide tools to encourage creativity and initiative. If internet-based learning environments are to benefit students, then it is important from the…

This article examined emotion competence in children exposed to domestic violence (DV). It also examined the hypothesis that children's emotional competence mediates relations between DV and children's later difficulties with peers and behavioral adjustment. DV was assessed when children were at the age of five, emotional competence was assessed…
