It has been shown that learned temporal information can be exploited to help facilitate the target identification in the attentional blink task. Here, we tested whether similar exploitation also worked on short-term temporal information, even when it did not reliably predict the target onset. In two experiments, we randomly manipulated either the interval between targets (T1 and T2; Experiment 1) or the temporal regularity of stimulus presentation (Experiment 2) in each trial. The results revealed evidence of effects of immediate temporal experience mainly on T2 performances but also occasionally on T1 performances. In general, the accuracy of T2 was enhanced when a longer inter-target interval was explicitly processed in the preceding trial (Experiment 1) or the temporal regularity, regardless of being explicitly or implicitly processed, was present in the stimulus stream, especially after T1 (Experiment 2). These results suggest that, under high temporal uncertainty, both interval and rhythmic cues can still be exploited to regulate the allocation of processing resources, thus, modulating the target identification in the attentional blink task, consistent with the view of flexible attentional allocation, and further highlighting the importance of the interplay between temporal processing and attentional control in the conscious visual perception.
研究表明,在注意瞬脱任务中,已习得的时间信息可被用于帮助促进目标识别。在此,我们测试了即便短期时间信息无法可靠地预测目标出现,类似的利用方式是否也适用于短期时间信息。在两项实验中,我们在每次试验中随机操控目标(T1和T2;实验1)之间的间隔或刺激呈现的时间规律性(实验2)。结果显示,即时时间体验的影响主要体现在T2的表现上,但偶尔也会体现在T1的表现上。总体而言,在前一次试验中明确处理了较长的目标间间隔时(实验1),或者刺激流中存在时间规律性(无论是否被明确或隐含地处理),尤其是在T1之后(实验2),T2的准确性会提高。这些结果表明,在高度的时间不确定性下,间隔和节奏线索仍可被用于调节加工资源的分配,从而在注意瞬脱任务中调节目标识别,这与灵活注意分配的观点一致,并进一步凸显了时间加工与注意控制之间的相互作用在有意识视觉感知中的重要性。
