Multitasking Induced Contextual Blindness
通过三个实验（序列反应时、空间线索搜索、驾驶模拟）发现，执行次要任务会抑制和掩盖时间与空间序列学习，导致无法利用环境线索引导注意力，对驾驶、航空等复杂技能领域有启示。
OBJECTIVE: To examine the impact of secondary task performance on contextual blindness arising from the suppression and masking of temporal and spatial sequence learning. BACKGROUND: Dual-task scenarios can lead to a diminished ability to use environmental cues to guide attention, a phenomenon that is related to multitasking-induced inattentional blindness. This research aims to extend the theoretical understanding of how secondary tasks can impair attention and memory processes in sequence learning and access. METHOD: We conducted three experiments. In Experiment 1, we used a serial reaction time task to investigate the impact of a secondary tone counting task on temporal sequence learning. In Experiment 2, we used a contextual cueing task to examine the effects of dual-task performance on spatial cueing. In Experiment 3, we integrated and extended these concepts to a simulated driving task. RESULTS: Across the experiments, the performance of a secondary task consistently suppressed (all experiments) and masked task learning (experiments 1 and 3). In the serial response and spatial search tasks, dual-task conditions reduced the accrual of sequence knowledge and impaired knowledge expression. In the driving simulation, similar patterns of learning suppression from multitasking were also observed. CONCLUSION: characterized by impairments in the ability to use environmental cues to guide attention and anticipate future events. APPLICATION: These findings have implications for both skill acquisition and skilled performance in complex domains such as driving, aviation, manufacturing, and human-computer interaction.
