This paper advocates for the adoption of Nexus Analysis as a robust analytical framework in Problem-Based Learning (PBL) research. Developed by Scollon and Scollon, Nexus Analysis offers a unique lens for examining the intricate dynamics of PBL by seamlessly integrating micro-level interactions with macrolevel societal discourses. The approach…

Epigenetics provides the opportunity to revolutionize our understanding of the role of genetics and the environment in explaining human behavior, although the use of epigenetics to study human behavior is just beginning. In this introduction, the authors present the basics of epigenetics in a way that is designed to make this exciting field…

Empirical research examining the situational characteristics of gambling and their effect on gambling behaviour is limited but growing. This experimental pilot investigation reports the first ever empirical study into the combined effects of both music and light on gambling behaviour. While playing an online version of roulette, 56 participants…

Individuals with Prader-Willi syndrome (PWS) are at risk for excessive daytime sleepiness (EDS) and disruptive behavior. This pilot study explores temporal characteristics of EDS and severe disruptive behavior across time of day and day of week in seven individuals with PWS (aged between 33 and 49 years) of whom five were matched to controls.…

Objective: Evidence is steadily accumulating that a preventable environmental hazard, child maltreatment, exerts causal influences on the development of long-standing patterns of antisocial behavior in humans. The relationship between child maltreatment and antisocial outcome, however, has never previously been tested in a large-scale study in…

This article presents new methods for modeling the strength of association between multiple behaviors in a behavioral sequence, particularly those involving substantively important interaction patterns. Modeling and identifying such interaction patterns becomes more complex when behaviors are assigned to more than two categories, as is the case…

The methodology of many studies that have identified specific genetic loci for disorders associated with mental retardation is criticized as failing to demonstrate an association between the behavior phenotype and the genetic marker. A more appropriate methodology using a multitrait-multimethod approach is suggested. (Author/JDD)

This paper on the behavioral manifestations of child sexual abuse first reviews previous research concerning child variables, parent/family variables, sexual abuse in combination with other maltreatment, and physiological outcomes. Criteria for future research are offered and specific research needs in the areas of developmental progression,…

Describes a simple, confidentiality-preserving, data-collection technique the Context-Determined, Rule-Generated, Pseudonym (CDRGP) Technique, capable of generating correlational data across multiple time-points. Experiments showed that students would respond to alcohol consumption questions using the technique and that no significant response…

How the nervous system encodes learning and memory processes has interested researchers for 100 years. Over this span of time, a number of basic neuroscience methods has been developed to explore the relationship between learning and the brain, including brain lesion, stimulation, pharmacology, anatomy, imaging, and recording techniques. In this…
