What has not been investigated much in previous literature is whether higher levels of distraction in lessons are more harmful to some learners than others. This…

This dissertation describes a research program focused on investigating learning strategies that could prevent individuals from showing inferior motor performance when performing under psychological pressure, a phenomenon known as "choking under pressure." Choking has been studied from the perspective of different theories. Each theory…

The purpose of this study was to explore the influence of curricular organization on student cognitive load and student performance in online learning environments. The findings of this study contribute to the development of usable instruction design principles for online education. This research study used the lens of cognitive load theory to…

The objective of this dissertation is to empirically test the effects of personalized gamification on individuals' performance. In order to achieve this objective, multiple experiments and case studies are conducted, and methods to help in the design of personalized and adaptive gamified applications are presented. Gamification aims to implement…

In Barkley's (1997a, 1997b) model of attention-deficit/hyperactivity disorder (ADHD), he proposes that working memory deficits resulting from ADHD may cause impairments in reading comprehension. ADHD has been associated with poorer processing speed and working memory as well as academic underachievement in some studies. However, more research is…

Three experiments investigated the effect of various kinds of reflection (within-task and post-task reflection) on learning a process control task. Also, two ways of providing learners with alternative ideas about task behavior, exposure to other's ideas and providing hints for task solution, were examined. The task involved a simulated…
