Context-based learning (CBL) environments are widely used in science education to create authentic learning opportunities. Contexts can be authentic through their relation to everyday life, to uncommon scientific phenomena, or to the chemical laboratory. Previous research revealed that students choose contexts that are authentic in different ways…

While the impact of behavioural and cognitive processes on online information searching behaviours have been studied in some depth, little is known about the impact of procedural and metacognitive processes on online information searching behaviours. In addition, although the literature contains studies examining online information searching…

This study investigated the factors underlying the estimation of learner self-confidence during explanations with a conversational agent in an online explanation task. Based on reviews of previous studies, we focused on how factors such as the learner's task activities and personal characteristics can be predictors. To examine these points, we…

Research into human decision-making has often sidestepped the question of search despite its importance across a wide range of domains such as search for food, mates, allies, visual targets or information. Recently, research on decisions from experience has made progress in finding out how individual characteristics shape search for information.…

Individuals with depressive symptoms typically show deficits in decision-making. However, most work has emphasized decision-making under gain-maximization conditions. A gain-maximization framework may undermine decision-making when depressive symptoms are present because depressives are generally more sensitive to losses than gains. The present…

This dissertation explores how participants express and interpret verbal cues of interaction involvement in dyadic conversations via text-based Instant Messaging (IM). Moreover, it seeks to discover differences in the way American participants and Chinese participants use verbal cues when they are highly, or lowly involved. Based on previous…

Cognitive performance is affected by an individual's characteristics and the environment, as well as by the nature of the task and the amount of practice at it. Mental performance tests range in complexity and include subjective estimates of mood, simple objective tests (reaction time), and measures of complex performance that require decisions to…

Impairments in either "cool" or "hot" processes may represent two pathways to deficient decision-making. Whereas cool processes are associated with cognitive and rational decisions, hot processes are associated with emotional, affective, and visceral processes. In this study, 168 boys were administered a card-playing task at ages 13 and 14 years…

Seven-year-olds completed a Posner cued attention task, under both neutral and affectively charged conditions. Compared to the traditional (affect-neutral) Posner task, performance in the affective Posner task was marked by dramatic decreases in reaction times (RTs), an increase in errors, an increased validity effect (difference in RTs to the…

The authors argue against the current view of task analysis which assumes that learning is a univariant process. They feel that learning is a multivariant process and that task analysis should also take into consideration an analysis of the learning task, the cognitive processes which affect the acquisition of the learning task, and the learner's…
