In this study a driving simulator was used to determine changes in mental effort in response to manipulations of steering demand. Changes in mental effort were assessed by using subjective effort ratings, physiology, and the standard deviation of the lateral position. Steering demand was increased by exposure to narrow lane widths and high density oncoming traffic while speed was fixed in all conditions to prevent a compensatory reaction. Results indicated that both steering demand factors influence mental effort expenditure and using multiple measures contributes to effort assessment. Application of these outcomes for adaptive automation is envisaged.
在这项研究中，使用驾驶模拟器来确定在操纵转向需求时心理努力的变化。通过使用主观努力评分、生理学和横向位置的标准偏差来评估心理努力的变化。通过在所有条件下保持速度固定而将车道变窄和迎面交通密度增加来增加转向需求，以防止补偿反应。结果表明，两个转向需求因素都影响心理努力的支出，并且使用多种措施有助于进行努力评估。预计这些结果将应用于自适应自动化。
