I report results from an experiment on the relationship between visual website complexity and users' mental workload. Applying a pupillary based workload assessment as a NeuroIS methodology, I found indications that a balanced level of navigation complexity, i.e., the number of (sub)menus, in combination with a balanced level of information complexity, is the best choice from a user’s mental wo...

BACKGROUND The inclusion of new technologies in education has motivated the development of studies on mental workload. These technologies are now being used in the teaching and learning process. The analysis enables identification of factors intervening in this workload as well as planning of overload prevention for educational activities using these technologies. OBJECTIVE To analyze the men...

The present experiment tested the merits of 9 common workload assessment techniques with relatively short periods of workload in a car-driving task. Twelve participants drove an instrumented car and performed a visually loading task and a mentally loading task for 10,30, and 60 s. The results show that 10-s periods of visual and mental workload can be measured successfully with subjective ratin...

Mental workload is a concept central to a range of disciplines (including cognitive psychology and ergonomics) that has given rise to various theoretical and methodological debates. As a result, researchers have used a number of techniques for measuring mental workload. Traditionally, three categories of measurement technique have been recognized: performance measures (e.g., the dual-task parad...

The focus of this study is the introduction of the construct of Human Mental Workload (HMW) in Web design, aimed at supporting current interaction design practices. An experiment has been conducted using the original Wikipedia and Google web-interfaces, and using two slightly different versions. Three subjective psychological mental workload assessment techniques (NASA-TLX, Workload Profile and...

INTRODUCTION Two great changes in developed countries are taking place: populations are ageing and becoming increasingly overweight. Combination of these factors with shift work is a risk factor for work ability and mental workload that are dynamic processes which change greatly throughout an individual's work life. The aim of this study was to investigate mental workload and work ability in te...

$\underline{Objective}$: Investigate effects of interactions between biomechanical, psychosocial and individual risk factors on the body's immune inflammatory responses. $\underline{Background}$: Current theories for low back pain causation do not fully account for the body's response to tissue loading and tissue trauma. $\underline{Methods}$: Two groups possessing a preference for the sensor o...

A navigator efforts to handle the ship for safe navigation by judging navigational information on own ship’s condition, targets and current-wind effect, and he/she has the responsibility of human lives and economical values under the judgment. The navigator keeps a mental workload during the navigational watch keeping. Therefore, we need the development of a support system to reduce the mental ...

Task interruption often has a significant negative impact on a user’s productivity and affective state. Cognitive theorists have argued that interrupting the execution of primary tasks at moments of lower mental workload would mitigate effects of interruption, yet knowing just where these moments occur remains elusive. In this article, we present empirical results from three user experiments ai...
