The relationship between attentional control and episodic representation was investigated in six experiments that employed a variant of the classic attentional blink paradigm. We introduced a task-irrelevant (unpredictive) color match between the first and second target stimulus in a three-stream rapid serial visual presentation task. When this match was present, the first target reliably elicited a priming benefit to the identification of the second, lateralized target. However, this was only the case when the identities of the targets did not belong to the same category (digits, letters, or symbols). When targets did belong to the same category, interference was observed instead of priming, particularly at Lag 1. Furthermore, when color was the target-defining feature, interference at Lag 1 gave way to priming at longer lags. The interference effect is attributed to partial overlap between competing episodic target representations, which affects the availability of their overlapping features for successive attentional selection in rapid serial visual presentation.
在六个实验中，研究了注意力控制和情景再现之间的关系，这些实验采用了经典的注意瞬脱范式的变体。我们在三通道快速序列视觉呈现任务中引入了第一个和第二个目标刺激之间的任务无关（不可预测）的颜色匹配。当这种匹配存在时，第一个目标可靠地引发了对第二个、偏向侧目标的识别的启动优势。然而，只有当目标的身份不属于同一类别（数字、字母或符号）时才会出现这种情况。当目标属于同一类别时，观察到的是干扰而不是启动，特别是在滞后 1 时。此外，当颜色是目标定义特征时，滞后 1 处的干扰让位于更长滞后处的启动。干扰效应归因于竞争情景目标表示之间的部分重叠，这会影响它们重叠特征在快速序列视觉呈现中连续注意力选择的可用性。
