This essay uses a case study to explore some of the reasons why understanding failures associated with diagnosis seems to have lagged behind the attention and understanding directed at failures in other aspects of healthcare (e.g., wrong patient/procedure, medication misadministration, etc). The goal is not to pose an alternative to many of the…

Parenting behaviors have received ample support as a mediator of the relationship between maternal affect and child behavior problems. The majority of these research efforts were based on a uni-dimensional conceptualization of maternal mood, even though decades of theory and research suggest that mood is multidimensional. We examined the mediating…

The pattern of perceived dysfunction associated with symptoms composing the externalizing childhood disorder syndrome was compared to the pattern characterizing the internalizing syndrome. In Study 1, undergraduate students (N = 205) judged the social impairment, academic/occupational impairment and personal distress associated with symptoms from…

Mankind's capacity to consume the earth's resources has overwhelmed nature's capacity to replenish itself, and people are polluting at a rate that nature cannot repair. This road leads inevitably to serious, and potentially fatal consequences. In this article, the author suggests that educators need to go beyond merely enabling students to…

S. O'Malley and D. Besner (2008) showed that additive effects of stimulus degradation and word frequency in reading aloud occur in the presence of nonwords but not in pure word lists. They argued that this dissociation presents a major challenge to interactive computational models of reading aloud and claimed that no currently implemented model is…

This study examined whether negative parental attributions for adolescent behaviour mediate the association between parental and adolescent depressive symptoms, and whether this relationship is moderated by adolescent gender. Mothers and fathers and 124 adolescents (76 girls and 48 boys; ages 14 to 18) participated. Adolescents were primarily…

This study integrated object-oriented programming instruction with transfer training activities in everyday tasks, which might provide a mechanism that can be used for efficient problem solving. Specifically, a Visual BASIC embedded with everyday tasks group was compared to another group exposed to Visual BASIC instruction only. Subjects were 40…

A meta-analytic review of empirical studies that have investigated incubation effects on problem solving is reported. Although some researchers have reported increased solution rates after an incubation period (i.e., a period of time in which a problem is set aside prior to further attempts to solve), others have failed to find effects. The…

The objective of this study was to investigate loss and the experience of emotional distress through a series of three studies. In Study 1, results indicated that when controlling for the total number of traumas experienced, children with loss traumas did not differ significantly from children with other types of traumas in terms of the level of…

The purpose of this study was to investigate the effects of type of question prompt and level of prior knowledge on non-routine mathematical problem solving. A computer game was blended within the pattern reasoning tasks, along with question prompts, in order to demonstrate and enhance the connections between viable problem-solving strategies and…

Building on research conducted over the past twenty years, this study examines teachers' attitudes toward teaching controversial issues in the classroom. Teachers' perceptions, previous research, and this survey indicated that social studies teachers do find value in discussing controversial issues, but perceived consequences may limit teachers in…

The null result of the Michelson-Morley experiment and the constancy of the one-way speed of light in the "rest system" are used to formulate a simple problem, to be solved by elementary geometry techniques using a pair of compasses and non-graduated rulers. The solution consists of a drawing allowing a direct visualization of all the fundamental…

The current study is part of a larger study that focused on within-group classroom discourse patterns of children in special education classes for language impairment (LI). Eleven children with LI aged 7-9 were examined across 4 classroom contexts: dialogic journal-writing, group lesson, peer play and sharing time. Amount and complexity of…

Bullying has been increasingly identified as a significant social problem. Although much of this attention has centered on the context of schooling, researchers are now beginning to recognize that workplaces are also arenas rife with abusive, bullying behaviors. Personality attributes of bullies and victims have received attention, but much less…

Objective: This research examined whether additional forms of family violence (partner-child aggression, mother-child aggression, and women's intimate partner violence [IPV]) contribute to children's adjustment problems in families characterized by men's severe violence toward women. Methods: Participants were 258 children and their mothers…
