چکیده

OBJECTIVE In this study, we investigated the effects of mild motion sickness and sopite syndrome on multitasking cognitive performance. BACKGROUND Despite knowledge on general motion sickness, little is known about the effect of motion sickness and sopite syndrome on multitasking cognitive performance. Specifically, there is a gap in existing knowledge in the gray area of mild motion sickness. METHOD Fifty-one healthy individuals performed a multitasking battery. Three independent groups of participants were exposed to two experimental sessions. Two groups received motion only in the first or the second session, whereas the control group did not receive motion. Measurements of motion sickness, sopite syndrome, alertness, and performance were collected during the experiment RESULTS Only during the second session, motion sickness and sopite syndrome had a significant negative association with cognitive performance. Significant performance differences between symptomatic and asymptomatic participants in the second session were identified in composite (9.43%), memory (31.7%), and arithmetic (14.7%) task scores. The results suggest that performance retention between sessions was not affected by mild motion sickness. CONCLUSION Multitasking cognitive performance declined even when motion sickness and soporific symptoms were mild. The results also show an order effect. We postulate that the differential effect of session on the association between symptomatology and multitasking performance may be related to the attentional resources allocated to performing the multiple tasks. Results suggest an inverse relationship between motion sickness effects on performance and the cognitive effort focused on performing a task. APPLICATION Even mild motion sickness has potential implications for multitasking operational performance.

Yawning as a behavioral marker of mild motion sickness and sopite syndrome.

INTRODUCTION Severe motion sickness is easily identifiable with sufferers showing obvious behavioral signs, including emesis (vomiting). Mild motion sickness and sopite syndrome lack such clear and objective behavioral markers. We postulate that yawning may have the potential to be used in operational settings as such a marker. This study assesses the utility of yawning as a behavioral marker f...

Sleep Duration in Rough Sea Conditions.

INTRODUCTION Environmental motion can affect shipboard sleep of crewmembers. Slamming and similar harsh motion may interfere with sleep, whereas mild motion and sopite syndrome may enhance sleep. If sleep needs vary by sea condition, this factor should be considered when assessing human performance at sea. The goal of this study was to assess sleep duration in different sea conditions. METHOD...

Sopite syndrome: a revised definition.

In 1976, Graybiel and Knepton proposed the term "sopite syndrome" to describe a symptom complex centering on drowsiness and lethargy related to motion sickness. However, existing descriptions and definitions of sopite syndrome have limitations in fully conveying the appropriate information to the reader. Our objective is to propose a revised definition providing a more adequate conceptual frame...

Investigating the Effect of a Selected Exercise Training Course on the Motion Sickness in Pilots and Flight Crew Members of the Army of the Islamic Republic of Iran

Background and Aim: Motion sickness is a natural and temporary response to unfamiliar motor stimuli which reduces performance in complex tasks that require constant attention. The aim of this research was to study the effect of a special exercise training period on motion sickness in the pilots and flight crews of the Army of the Islamic Republic of Iran. Methods: In this study, 20 pilot studen...
