Background: Intraindividual variability in reaction times (RT variability) has garnered increasing interest as an indicator of cognitive and neurobiological dysfunction in children with attention deficit hyperactivity disorder (ADHD). Recent theory and research has emphasized specific low-frequency patterns of RT variability. However, whether…

While dehydration has negative effects on memory and attention, few studies have investigated whether drinking water can enhance cognitive performance, and none have addressed this in a real-world setting. In this study we explored the potential benefits of the availability of water for undergraduates. The exam performance of students who brought…

This study explored the effectiveness of external representations presented together with compare word problems, and whether such effectiveness was moderated by working memory. Participants were 49 secondary school students. Each participant solved 48 problems presented in 4 presentation types that included 2 difficulty treatments (number of steps…

An investigation was carried out to examine the effects of cognitive style on learners' performance and interaction during complex problem solving with a computer modeling tool. One hundred and nineteen undergraduates volunteered to participate in the study. Participants were first administered a test, and based on their test scores they were…

The present article examines how suitable expository films are for learning. This question was motivated by the assumption that films are processed in a superficial manner. However, previous research has been dominated by the analyses of outcome measures and has never taken a look at online measures so that no clear conclusions have been drawn.…

The present article focuses on 13-year-old girls' meaning-making processes during participation in a manual-based psycho-educational course at school. Drawing on childhood studies and ethnographic investigations of subjectivity, the author explores how the course is realized in practice. The analysis, based on video-recordings of 13 classes, shows…

This study reports the result of literature review in regards to learning outcome studies and presents a framework that integrates content types with learning outcomes. Analysis of learning outcome studies between 1992 and 2006 using the ERIC database indicated that most empirical studies have assessed the learning outcome at lower levels of…

Language and oculomotor disturbances are 2 of the best replicated findings in schizophrenia. However, few studies have examined skilled reading in schizophrenia (e.g., Arnott, Sali, Copland, 2011; Hayes & O'Grady, 2003; Revheim et al., 2006; E. O. Roberts et al., 2012), and none have examined the contribution of cognitive and motor processes that…

The use of computers for learning is often a complex issue which involves cognitive and metacognitive concerns. This gives rise to our interest in examining the intention to use technology with relation to regulation of cognition. The use of technology for learning would necessarily require learners to exercise a certain level of regulation over…

For accurate reading comprehension, readers must first learn to map letters to their corresponding speech sounds and meaning, and then they must string the meanings of many words together to form a representation of the text. Furthermore, readers must master the complexities involved in parsing the relevant syntactic and pragmatic information…

Objective:This retrospective study used A Quick Test of Cognitive Speed (AQT) processing-speed and efficiency measures for evaluating sensitivity and monitoring effects during pharmacological treatment of adults with ADHD. Method: Color (C), form (F), and color-form (CF) combination naming were administered to 69 adults during outpatient…

This dissertation proposes a dynamical computational model of the timecourse of phonological parameter setting. In the model, phonological representations embrace phonetic detail, with phonetic parameters represented as activation fields that evolve over time and determine the specific parameter settings of a planned utterance. Existing models of…

Although a large part the Physics Education Research (PER) literature investigates students' conceptual understanding in physics, these investigations focus on qualitative, conceptual reasoning. Even in modeling expert problem solving, attention to conceptual understanding means a focus on initial qualitative analysis of the problem; the equations…

Previous cognitive models of memory have not comprehensively taken into account the internal cognitive load of chunking isolated information and have emphasized the external cognitive load of visual presentation only. Under the Virk Long Term Working Memory Multimedia Model of cognitive load, drawing from the Cowan model, students presented with…

Students with attention-deficit/hyperactivity disorder (ADHD) make up approximately 5% of the school-aged population and they often experience significant difficulties in school, particularly in the areas of academics, disruptive behavior, and social relationships. A diagnosis of ADHD does not provide guidance for creating interventions to address…
