Alcohol's psychological, cognitive, and motor effects contribute to rape. Based on theory and past research, we hypothesized that there would be a curvilinear relationship between the quantity of alcohol consumed by perpetrators and how aggressively they behaved. Moderate levels of intoxication encourage aggressiveness; however, extreme levels…

Background: Depressed adults may show impairment in switching attention from one task to another. Rumination on negative thoughts is associated with the onset and persistence of depressive episodes. It is unclear if such mood-related ruminations are specifically associated with slowed ability in switching attention from one task to another.…

Background: Behavioral genetic studies provide strong evidence that attention-deficit/hyperactivity disorder (ADHD) has a substantial genetic component. Yet, due to the complexity of the ADHD phenotype, questions remain as to the specific genes that contribute to this condition as well as the pathways from genes to behavior. Endophenotypes, or…

While some research has been conducted on the manner in which Christian athletes utilize their faith to cope with the dominant culture of winning, there appears to be a relative paucity of investigation on the manner in which elite coaches function in this environment. The purpose of this study was to describe an elite intercollegiate coach's…

Most research in the area of Computer Algebra Systems (CAS) has been designed to compare the effectiveness of instructional technology to traditional lecture-based formats. While results are promising, research also indicates evidence of the steep learning curve imposed by the technology. Yet no studies have been conducted to investigate this…

This paper focuses on the cognitive processes that occur while students are exploring motion graphs. In a classroom experiment, we examine how high-school students (aged 17), with backgrounds in calculus and physics, interpret the graphs they create through drawing the path of the movement of their hand with a computer mouse. Based on recent, and…

Technology in secondary schools has become of increasing interest as the power of the micro chip has developed. For the students of Mathematics, computers and hand held graphic calculators need to be accessible to all. They are relevant to the needs of the students' courses and to support and develop their Mathematical learning (Smith, 1997).…

Decision-makers in organizations often make what appear as being intuitively obviously and reasonable decisions, which often turn out to yield unintended outcomes. The cause of such ineffective decisions can be a combination of cognitive biases, poor mental models of complex systems, and errors in thinking provoked by anxiety, all of which tend to…

Detection thresholds for two visual- and two auditory-processing tasks were obtained for 73 children and young adults who varied broadly in reading ability. A reading-disabled subgroup had significantly higher thresholds than a normal-reading subgroup for the auditory tasks only. When analyzed across the whole group, the auditory tasks and one of…

This study evaluated a model of reading skills among early adolescents (N=174). Measures of family history, achievement, cognitive processes and self-perceptions of abilities were obtained. Significant relationships were found between family history and children's single-word reading skills, spelling, reading comprehension, orthographic processing…

Two experiments investigated whether young and old adults can temporarily remove information from a capacity-limited central component of working memory (WM) into another component, the activated part of long-term memory (LTM). Experiment 1 used a modified Sternberg recognition task (S. Sternberg, 1969); Experiment 2 used an arithmetic…

Little is known about the way that teachers articulate notions of variation in their own words. The study reported here was conducted with 17 prospective secondary math and science teachers enrolled in a preservice teacher education course which engaged them in statistical inquiry of testing data. This qualitative study examines how these…

The purpose of this paper is to present a participatory multimedia learning model for use in designing multimedia learning environments that support an active learning process, creative participation, and learner engagement. Participatory multimedia learning can be defined as learning with systems that enable learners to produce part of the…

Our editor-at-large puts questions to a political scientist--the former higher-education advisor to the Coalition Provisional Authority in Iraq--who replies with skepticism about prospects for our efforts to restore a university system in Iraq and reconstitute that troubled society in our image. Building an informed democracy, John Agresto…

This article reports the findings of part of a major study exploring the disciplinary writing processes and perceptions of 15 Chinese graduate students in sciences and engineering at a major Canadian university. The findings relate to the thinking languages of the participants in writing disciplinary assignments. The study reveals that whether an…
