Successful performance in complex dynamic environments depends on domain-dependent factors, such as situational awareness (SA). Underlying SA in a domain are domain-independent cognitive abilities in perception, memory, attention and executive control. Individuals with lower underlying ability perform relatively poorly in complex dynamic real-world tasks. The first experiment examined whether cognitive skills training could overcome limitations in underlying SA ability that impact on complex dynamic task performance. Participants were taught a mix of cognitive management strategies (e.g. divided and focused attention and visual search) in a simulated air traffic control task. A second experiment investigated the link between underlying SA ability, TRACON and SAGAT, a widely used measure of domain-specific SA. In a third experiment, the focus was on encouraging participants to plan ahead and consider the interrelations of elements (aircraft) in the environment. Whilst both training methods ameliorated the negative impact that lower SA ability had on complex dynamic task performance, the results of the third study indicated that this may have been achieved through improved planning behaviour. Finally, participants with higher underlying SA ability performed well irrespective of training condition.
在复杂动态环境中的成功表现取决于领域相关因素,如态势感知(SA)。一个领域的基础态势感知是感知、记忆、注意力和执行控制方面与领域无关的认知能力。基础能力较低的个体在复杂动态的现实世界任务中表现相对较差。第一个实验研究了认知技能训练是否能克服基础态势感知能力的局限,这些局限会影响复杂动态任务的表现。在模拟空中交通管制任务中,向参与者传授了多种认知管理策略(如分散和集中注意力以及视觉搜索)。第二个实验研究了基础态势感知能力、终端雷达管制区(TRACON)和态势感知全局评估技术(SAGAT,一种广泛使用的特定领域态势感知测量方法)之间的联系。在第三个实验中,重点是鼓励参与者提前规划并考虑环境中各元素(飞机)之间的相互关系。虽然两种训练方法都减轻了较低态势感知能力对复杂动态任务表现的负面影响,但第三项研究的结果表明,这可能是通过改善规划行为实现的。最后,基础态势感知能力较高的参与者无论训练条件如何都表现良好。
