In the present research, we examined the relative roles of domain-general and domain-specific individual difference characteristics in complex cognitive task performance. Specifically, we examined the impact both of working memory (WM) capacity and of acquired skills used to encode presented information in an accessible form in long-term working memory (LTWM) on performance in a complex aviation task environment. Measures of WM capacity and LTWM skill served as performance predictors. A criterion measure of task performance was related to the predictor measures. The results indicated that an increase in LTWM skill decreases the role of WM capacity as the determinant of complex task performance, although both measures are important performance predictors. We discuss how the two distinct WM constructs coexist and interact to support complex task performance.
在本研究中，我们考察了一般领域和特定领域个体差异特征在复杂认知任务表现中的相对作用。具体而言，我们考察了工作记忆（WM）容量以及用于将呈现的信息以可访问的形式编码到长期工作记忆（LTWM）中所习得的技能，对复杂航空任务环境中表现的影响。WM容量和LTWM技能的测量作为表现预测指标。任务表现的标准测量指标与预测指标相关。结果表明，LTWM技能的提高降低了WM容量作为复杂任务表现决定因素的作用，尽管这两个指标都是重要的表现预测指标。我们讨论了这两种不同的WM结构如何共存和相互作用以支持复杂任务表现。
