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

Recruiting

• Conditions: Cognitive Load

• Registration Number: NCT05081544
• Lead Sponsor: Direction Centrale du Service de Santé des Armées

Brief Summary

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.

Primary Outcome Measures

Name	Time	Method
Cognitive load level	At enrollment (Day 1)	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).
