目的：在双任务范式下，利用两个言语任务，探讨绩效理论和先前的双任务结果。背景资料：随着时间的推移，警觉性表现下降，或警觉性递减，以及有限的双重任务处理能力可能是由有限的心理资源。资源理论家会建议删除任务要求，以避免认知超载，而无意识理论家可能会建议增加引人入胜的任务要求，以防止无聊。先前的研究表明，言语自由回忆和语义警戒任务之间的干扰，但探索更大的生态有效性的任务是必要的。方法：采用叙事记忆任务和语义警戒任务同时进行。相对性能损伤进行了比较，以前的双任务配对。结果：语义警戒任务导致叙事记忆任务的成绩下降，反之亦然。没有观察到的警惕递减，干扰的程度比语义警戒任务与自由回忆任务配对。结论：资源理论得到支持，虽然被动学习的影响，在语义警戒任务与新的刺激可能会阻止警戒递减。这种干扰比之前类似的双任务配对要少，但即使是听对话或故事这样的常规任务也会损害其他任务的表现。适用范围：更好地理解资源理论和双任务绩效结果可以帮助告知可行的任务负载，并提高高风险和其他职业操作员的效率和安全性。
Objective: Two verbal tasks were utilized in a dual-task paradigm to explore performance theories and prior dual-tasking results. Background: Both the decline in vigilance performance over time, or vigilance decrement, and limited dual-tasking ability may be explained by limited mental resources. Resource theorists would recommend removing task demands to avoid cognitive overload, while mindlessness theorists may recommend adding engaging task demands to prevent boredom. Prior research demonstrated interference between a verbal free recall and semantic vigilance task, but exploring tasks with greater ecological validity is necessary. Method: A narrative memory task and semantic vigilance task were performed individually and simultaneously. Relative performance impairments were compared to a previous dual-task pairing. Results: The semantic vigilance task caused performance degradation to the narrative memory task and vice versa. A vigilance decrement was not observed, and the interference was to a lesser extent than when the semantic vigilance task was paired with a free recall task. Conclusion: Resource theory was supported, though passive learning effects during a semantic vigilance task with novel stimuli may prevent a vigilance decrement. The interference was less than that of a previous similar dual-task pairing, but even tasks as routine as listening to a conversation or story can impair other task performance. Application: A better understanding of resource theory and dual-task performance outcomes can help inform feasible task loads and improve efficiency and safety of operators in high-risk and other professions.
