Impact of Multi-tasking Situations on the Dismounted Soldier's Cognitive Load (SiMuCCoDé)

The increased complexity of the dismounted combatant's equipment can result in a strain on the various senses (e.g., visual, auditory) that can exceed an individual's limited information processing abilities. The combatant may thus be cognitively overloaded in multi-tasking operational situations.

There has been a great deal of research conducted on cognitive load. A battery of multitasking tests has been developed in the field of aeronautics, but, to our knowledge, no measurement of cognitive load specifically dedicated to combatants has been conducted yet.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Cognitive load level	Cognitive load level will be measured using NASA-TLX questionnaire. NASA-TLX questionnaire comprises 6 dimensions (mental demands, physical demands, time demands, performance, effort and frustration). Each dimension has a score ranging from 0 (low cognitive load) to 100 (high cognitive load), except for the "performance" dimension, whose score ranges from 0 (good performance) to 100 (low performance).
