Viding, Essi – Journal of Child Psychology and Psychiatry, 2004
Background: Psychopaths are not only antisocial, but also have a callous and unemotional personality profile. This article selectively reviews evidence that psychopathic personality traits are an important factor in understanding and predicting the development of persistent antisocial conduct. Cognitive neuroscience research and more tentative…

Erduran, Sibel – Science & Education, 2005
Even though philosophical themes in science education have been advocated for several decades, little attention has been paid to how these themes can be contextualized in the teaching of a particular domain of science. The purpose of this paper is to provide an example theoretical framework for applying a philosophical theme, reduction, in…

Runyan, Jason D.; Moore, Anthony N.; Dash, Pramod K. – Learning & Memory, 2005
The prefrontal cortex is involved in the integration and interpretation of information for directing thoughts and planning action. Working memory is defined as the active maintenance of information in mind and is thought to lie at the core of many prefrontal functions. Although dopamine and other neurotransmitters have been implicated, the…

Caccavo, Frank, Jr.; Clegern, William; Miller, Isaac; Montoya, Crystal – American Biology Teacher, 2003
Metabolism, the sum of all chemical reactions within a living organism, is one of the most fundamental concepts presented in introductory microbiology courses. However, it is often difficult for instructors to effectively translate perfunctory diagrams of glycolysis, the Krebs cycle, and the electron transport chain in a way that is meaningful to…

Blair, R. J. R.; Peschardt, K. S.; Budhani, S.; Mitchell, D. G. V.; Pine, D. S. – Journal of Child Psychology and Psychiatry, 2006
The current review focuses on the construct of psychopathy, conceptualized as a clinical entity that is fundamentally distinct from a heterogeneous collection of syndromes encompassed by the term "conduct disorder". We will provide an account of the development of psychopathy at multiple levels: ultimate causal (the genetic or social primary…
