“…The development of multidimensional measures led inevitably to an inclusive framework for mental workload. The cost of this integration is dissociation between different measures of mental workload, e.g., Yeh and Wickens (1988), and an integrated workload concept that remains poorly defined from a psychometric perspective (Matthews et al, 2015).…”

“…But this notion has always been problematic because resources are a general-purpose metaphor with limited explanatory powers (Navon, 1984) that incorporate both cognitive processes (e.g., attention, memory) and energetical constructs (e.g., mental effort) in ways that are difficult to delineate or operationalize. The allegorical basis of resources almost guarantees an abstract level of explanation (Van Acker et al, 2018) that is accompanied by divergent (Matthews et al, 2015), and sometimes contradictory operationalizations (Yeh and Wickens, 1988;Annett, 2002).…”

“…Thus, two tasks demanding perceptual-central resources will interfere more if one of them only requires response-related resources. Furthermore, different MWL measures do not always produce similar results (de Waard and Lewis-Evans 2014; Matthews et al 2015;Yeh and Wickens 1988). This could indicate that different measures may be sensitive to different levels of task demands (de Waard 1996), but also to demands placed on different processing resources (Wickens 2008).…”

“…En deuxième lieu, les études montrent plusieurs similitudes entre le stress et le TME en ce qui concerne les paramètres physiologiques (augmentation du cortisol, accélération du rythme cardiaque, instabilité glycémique) (Chaput et al, 2008;Fairclough & Houston, 2004;Matthews, Reinerman-Jones, Barber, & Abich IV, 2015). En ce qui a trait à l'autorégulation, les auteurs exposent toutefois que le stress et le TME sont gérés de façon bien distincte : alors que la réponse à une émotion est automatique, sans effort et toujours prioritaire (voie automatique) par rapport aux buts cognitifs, le TME exige un effort conscient et volontaire, consumant par le fait même de l'énergie psychologique (voie volontaire) (Carver & Scheier, 2011;Mischel & Ayduk, 2011).…”
