For safety reasons, in-vehicle dialogue systems should be able to take the cognitive load of the driver into consideration. However, it is important to distinguish between two types of cognitive load, namely if the cognitive load is affecting the driving behaviour or not. We will present findings from a data collection carried out in the DICO project1, where the dialogue behaviour under high co...

Cognitive load measurement during handwriting has broad prospects both for computer-assisted education and for user interface adaptation, but it is difficult to achieve due to the lack of established methods for extracting behavioral information from writing that is indicative of cognitive load variations. This study aimed to measure cognitive load with the direct information available from the...

In this paper we use pupil diameter as an indicator for measuring cognitive load for six different tasks on common web maps. Two eye tracking data sets were collected for different basemaps (37 participants and 1,328 trials in total). We found significant differences in mean pupil diameter between tasks, indicating low cognitive load for free exploration, medium cognitive load for search, polyg...

Problems in hypertext learning seem to relate with high levels of cognitive load that learners suffer during hypertext reading. One important factor that can increases cognitive load is the number of links per page (DeStefano & LeFevre, 2007). Several navigation support techniques, such as link suggestions, have been proposed to reduce cognitive load. In an experiment we tested the effects of n...

the present study aims to investigate language learners’ cognitive processes in on-line esp courses. three modes of inquiry are used: think-aloud protocol analysis, screen capture analysis, and correlation analysis. the theoretical foundations for the evaluation of the cognitive aspect of ferdowsi univeristy of mashhad e-learning system are drawn from cognitive load theory, cognitive apprentice...

Cognitive load theory (CLT) provides us guiding principles in the design of learning materials. CLT differentiates three different kinds of cognitive load -intrinsic, extraneous and germane load. Intrinsic load is related to the learning goal, extraneous load costs cognitive resources but does not contribute to learning. Germane load can foster learning. Objective methods, such as eye movement ...

Cognitive Load Theory is one of the most powerful research frameworks in educational research. Beside theoretical discussions about the conceptual parts of cognitive load, the main challenge within this framework is that there is still no measurement instrument for the different aspects of cognitive load, namely intrinsic, extraneous, and germane cognitive load. Hence, the goal of this paper is...

In this article, we discuss cognitive load measurement techniques with regard to their contribution to cognitive load theory (CLT). CLT is concerned with the design of instructional methods that efficiently use people’s limited cognitive processing capacity to apply acquired knowledge and skills to new situations (i.e., transfer). CLT is based on a cognitive architecture that consists of a limi...

In natural situations, speech perception often takes place during the concurrent execution of other cognitive tasks, such as listening while viewing a visual scene. The execution of a dual task typically has detrimental effects on concurrent speech perception, but how exactly cognitive load disrupts speech encoding is still unclear. The detrimental effect on speech representations may consist o...

OBJECTIVE This study investigates the effect of cognitive load on guidance of visual attention. BACKGROUND Previous studies have shown that cognitive load can undermine driving performance, particularly drivers' ability to detect safety-critical events. Cognitive load combined with the loss of exogenous cues, which can occur when the driver briefly glances away from the roadway, may be partic...
