Selection history is widely accepted as a vital source in attention control. Reward history indicates that a learned association captures attention even when the reward is no longer presented, while statistical learning indicates that a learned probability exerts its influence on attentional control (facilitation or inhibition). Existing research has shown that the effects of the reward history and statistical learning are additive, suggesting that these two components influence attention priority through different pathways. In the current study, leveraging the temporal resolution advantages of EEG, we explored whether these two components represent independent sources of attentional bias. The results revealed faster responses to the target at the high-probability location compared to low-probability locations. Both the target and distractor at high-probability locations elicited larger early Pd (50-150 ms) and Pd (150-250 ms) components. The reward distractor slowed the target search and elicited a larger N2pc (180-350 ms). Further, no interaction between statistical learning and the reward history was observed in RTs or N2pc. The different types of temporal progression in attention control indicate that statistical learning and the reward history independently modulate the attention priority map.
选择历史被广泛认为是注意力控制的重要来源。奖励历史表明，即使奖励不再出现，习得的关联也会吸引注意力，而统计学习表明，习得的概率会对注意力控制（促进或抑制）产生影响。现有研究表明，奖励历史和统计学习的效果是累加的，这表明这两个成分通过不同途径影响注意力优先级。在本研究中，利用脑电图的时间分辨率优势，我们探讨了这两个成分是否代表注意力偏差的独立来源。结果显示，与低概率位置相比，对高概率位置的目标反应更快。高概率位置的目标和干扰项均引发了更大的早期Pd（50 - 150毫秒）和Pd（150 - 250毫秒）成分。奖励干扰项减缓了目标搜索并引发了更大的N2pc（180 - 350毫秒）。此外，在反应时间或N2pc中未观察到统计学习与奖励历史之间的相互作用。注意力控制中不同类型的时间进程表明，统计学习和奖励历史独立调节注意力优先级图谱。
