In the wake of the information explosion and rapidly progressing technology [Mayer, R. E. (2001). "Multimedia learning". Cambridge: University Press] formulated a theory that focused on human cognition, rather than technology capacity and features. By measuring the effect of cognitive individual differences and display design manipulations on…

Current theorists stress the context-specificity of social behaviors and social cognitions. Although researchers have started to investigate the relationship as one context that might influence social cognitions, relatively little is known about the influence of relational context on the social goals endorsed by children and adolescents. The…

Item response theory modeling was applied to the data of 1,321 bereaved individuals who completed the Dutch version of the Inventory of Complicated Grief-Revised (ICG-R)--a 29-item self-report measure of complicated grief (CG). The authors aimed to examine the information that each of the ICG-R items contributes to the measurement of overall CG…

The author conducted a partial replication of Stanley Milgram's (1963, 1965, 1974) obedience studies that allowed for useful comparisons with the original investigations while protecting the well-being of participants. Seventy adults participated in a replication of Milgram's Experiment 5 up to the point at which they first heard the learner's…

To explore the possible neural foundations of individual differences in intelligence test scores, we examined the associations between Raven's Matrices scores and two tasks that were administered in a functional magnetic resonance imaging (fMRI) setting. The two tasks were an n-back working memory (N = 37) task and inspection time (N = 47). The…

Developmental research has examined individual differences, cognitive developmental bases, and psychosocial factors of adolescent risk-taking. The current paper presents a general adolescent risk-taking model that adopts aspects of each of these primarily independent areas. This model is based on the premise that adolescents take risks when (a)…

There is a strong association between pathological gambling and substance abuse. The objective of this study is to identify the differences between substance abusers with and without gambling problems. A cross sectional study was conducted interviewing with Addiction Severity Index (ASI) and South Oaks Gambling Screen (SOGS), alcohol and drug…

In this 2-experiment study, experimental analyses of phoneme blending and segmenting skills were conducted with four-first grade students. Intraindividual analyses were conducted to identify the effects of classroom-based instruction on blending phonemes in Experiment 1. In Experiment 2, the effects of an individualized intervention for the…

As indicated by the distance effect and the spatial-numerical association of response codes (SNARC) effect, natural numbers are mentally represented on a number line. Purportedly, this number line underlies children's number sense, which supports the acquisition of more advanced mathematical competencies. In 3 studies with a total of 429 fifth and…

Research has shown that animals and humans habituate on a variety of behavioral and physiological responses to repeated presentations of food cues, and habituation is related to amount of food consumed and cessation of eating. The purpose of this article is to provide an overview of experimental paradigms used to study habituation, integrate a…

This study takes an individual differences' perspective on performance feedback effects in psychometric testing. A total of 105 students in a mainstream secondary school in North East England undertook a cognitive ability test on two occasions. In one condition, students received item-specific accuracy feedback while in the other (standard…

This study examines whether disagreeable youth are distinct from aggressive youth, victimized youth, and withdrawn youth. Young adolescents (120 girls and 104 boys, M = 13.59 years old) completed personality and adjustment inventories. Aggression, withdrawal, and victimization scores were derived from peer nominations (N = 807). Cluster analyses…

After presenting some of the main arguments against certain narrow concepts of second language practice, this article argues that a broader concept of practice, still focused on form or even forms, but with due attention to form-meaning links and with appropriate sequencing of activities to ensure declarative knowledge first, followed by its…

Inequality, family and school characteristics were linked to student achievement as shown by multi-level analyses of 107,975 15 year olds' mathematics tests and questionnaires in 41 countries. Equal distribution of country and school resources were linked to higher mathematics scores. Students scored higher in families or schools with more…

Language development has long been associated with motor development, particularly manual gesture. We examined a variety of motor abilities--manual gesture including symbolic, meaningless and sequential memory, oral motor control, gross and fine motor control--in 129 children aged 21 months. Language abilities were assessed and cognitive and…
