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…

Acculturation and language proficiency have been found to be inter-related both from the perspective of second language acquisition (Schumann, 1978, 1986) and socio-psychological adaptation in cross-cultural contacts (Ward, Bochner, & Furnham, 2001). However, the predictions as to the effect of a particular strategy on success differ, with…

Objectives: Evaluators examining the same evidence often arrive at substantially different conclusions in forensic assessments of child sexual abuse (CSA). This study attempts to identify and quantify subjective factors that contribute to such disagreements so that interventions can be devised to improve the reliability of case decisions. Methods:…

In recent years there has been an unprecedented increase in support staff in schools in England and Wales. There were widespread expectations that this will be of benefit to teachers and pupils but there has been little systematic research to address the impact of support staff. This study used a naturalistic longitudinal design to investigate the…

Pubertal development is a nonlinear process progressing from prepubescent beginnings through biological, physical, and psychological changes to full sexual maturity. To tether theoretical concepts of puberty with sophisticated longitudinal, analytical models capable of articulating pubertal development more accurately, we used nonlinear…

Despite the necessity of the decision to terminate memory search in many real-world memory tasks, little experimental work has investigated the underlying processes. In this study, the authors investigated termination decisions in free recall by providing participants an open-ended retrieval interval and requiring them to press a stop button when…

When any object of external sense, or of thought, occupies the mind in such a degree that a person does not receive a clear perception from any other one, he is said to attend to it. The principle that is excited in his mind by a perception, or thought, is commonly called the faculty of attention; a faculty which may be justly said to be the…

The concept of approach to learning was first identified by Marton and Saljo in 1976. Numerous researchers have conducted studies on students' approaches to learning since 1976. There appears considerable confusion in the literature concerning the terms cognitive styles and learning styles. Therefore, there is a remarkable ambiguity about the…

This research investigated the cognitive processes underlying remember-know judgments in terms of contextual binding in multidimensional source memory. Stochastic dependence between the retrieval of different context attributes, which formed the empirical criterion of binding, was observed for remembered items but not for known items. Experiment 1…

Increasing interest in multiple forms of nonacademic intelligences in addition to the well-established intelligent quotient (IQ) to explain individual success has triggered a need for clear establishment of the theoretical and empirical connection among these constructs. As such, this article explores the interrelationship that exists among three…
