“…These variations can be independent of amplitude. Recent findings (LeDuc et al, 2005;Di Stasi et al, 2010) have demonstrated that mental workload and/or fatigue affect the dynamics of saccades and that PV could be an appropriate measure of this relationship. Here we report further results supporting the idea that PV represents an alternative measure for assessing mental workload in complex environments.…”

“…In the cognitive field, it has been shown that fatigue makes arousal gradually decrease, whereas load is arousing (Di Stasi et al, 2010. However, both effort and fatigue are hedonically negative.…”

“…Following the analogy, we distinguish between mental fatigue (namely, a reduction in mental performance, mainly, but not only, attributable to sustained cognitive effort) and cognitive effort. Recent studies have actually dissociated mental effort from mental fatigue, by measuring their differential effects on eye motility (Di Stasi, Antolí, & Cañas, 2011;Di Stasi, Renner, Staehr, Helmert, Velichkovsky, Cañas, Catena, & Pannasch, 2010).…”

Título: El efecto de la carga de trabajo mental en la intensidad y la dinámi-ca emocional del esfuerzo percibido. Resumen: El esfuerzo percibido, medido por escalas psicométricas, ha demostrado ser una herramienta válida para evaluar la carga de entrenamiento, que correlaciona altamente con dimensiones fisiológicas y mecáni-cas del esfuerzo físico. Sin embargo, poco se sabe sobre los correlatos emocionales del esfuerzo, y cómo la percepción del esfuerzo es influenciada por la carga de trabajo mental. En los dos experimentos descritos, se encontró que la valoración del esfuerzo percibido (RPE) estaba significativamente influenciada por la carga mental (generada por medio de una tarea cognitiva, sin relación, pero temporalmente superpuesta con la tarea física) durante la recuperación activa después de haber alcanzado el agotamiento durante el ejercicio, pero no durante el ejercicio incremental. Es importante destacar que el esfuerzo percibido correlacionó fuertemente con los valores emocionales / hedónicos de valencia, pero no así con los valores de la activación. Estos hallazgos refuerzan el valor motivacional del esfuerzo percibido y su vinculación con otros constructos psicológicos. Palabras claves: Carga mental; esfuerzo percibido; esfuerzo físico; fatiga; ejercicio; motivación.Abstract: Perceived exertion, as measured by psychometric scales, has been proven to be a valid tool to assess training load, and to highly correlate with physiological and mechanical dimensions of physical effort. However, little is known about the emotional correlates of exertion, and how perceived exertion is influenced by mental workload. In the two experiments reported here, ratings of perceived exertion (RPE) were found to be significantly influenced by mental workload (generated by means of a cognitive task, unrelated to, but temporally overlapping with the physical task) during active recovery after exhausting exercise, but not during incremental exercise. Importantly, perceived exertion was found to strongly correlate with reported emotional/hedonic valence, but not so tightly with reported arousal. These findings strengthen the motivational value of perceived exertion, and its linkage to other psychological constructs

“…Selon Reimer, Mehler, Coughlin, Roy et Dusek (2011), le passage d'une simple tâche de conduite à une double tâche augmente la charge de travail (hausse de la fréquence cardiaque moyenne) et dégrade les performances avec une perte du contrôle latéral du véhicule sur la voie. De plus, plusieurs études ont montré que les environnements très complexes menaient à une hausse subjective de la charge de travail et à des dégradations de performances (De Waard, Brookhuis, & Hernandez-Gress, 2001;Baldauf, Burgard, & Wittmann, 2009;Di Stasi et al, 2010).…”

SUMMARY OVERLOAD AS A FUNCTION OF DRIVING ENVIRONMENT, DRIVERS' EXPERIENCE AND THEIR INTERNAL STATEThe factors that lead to young drivers having accidents have been the subject of much research. In this article, we review the current literature concerning the links between the complexity of the driving environment, driving experience, workload, anxiety, vigilance, and driving performance. First, we outline the features that characterize the environment complexity and the drivers' experience. Automatic and controlled processing is typically found in simple and complex environments, respectively. It varies as a function of driving experience automation that increases with experience. The lowest levels of cognitive load and best performance are found among more experienced drivers compared to novices. Secondly, overload can be explained as a function of the environment complexity and driving experience. Several studies confirm theories stating that simple and very complex environments are particularly prone to overload; at the same time, workload is lower, and performance is better for experienced drivers compared to novices. Finally, we examine the literature in order to understand how levels of anxiety and vigilance modulate the effects of environmental complexity and a driver's experience on overload. According to the literature, costly environments (i.e. simple and very complex), combined with a lack of experience can result in high energy expenditure. A high level of anxiety and a lack of vigilance can thus impair performance through an increase in workload. Moreover, the increased workload may be directly due to the costly environment and lack of experience, which can increase energy expenditure, raise anxiety, and lower vigilance. Drawing up on various theories and empirical studies that find a link between these factors, the aim is to establish a model of the links between the characteristics of the driving environment and the individual characteristics that lead to road accidents. That will make it possible to develop specific ways to raise awareness, and new driving training modules.

Saccadic Peak Velocity Sensitivity to Variations in Mental Workload

Abstract: Saccadic peak velocity is affected by variations in mental workload during ecologically valid tasks. We conclude that saccadic peak velocity could be a useful diagnostic index for the assessment of operators' mental workload and attentional state in hazardous environments.
