ABSTRACT

Spatial distractor processing is impacted by the availability of spatial attention. What is less clear is the extent to which temporal selection alters such spatial selection, when considering response selection. The attentional blink (AB) paradigm is well-suited for studying this question. In this study, we adapted the AB task to measure response times. In Experiment 1, participants identified two targets (T1 and T2), where T2 was presented after T1 at varying lags. Temporal selection is said to select distractors only when T2 is presented within certain lags. Confirming this, an AB effect was found with slower responses to T2 at short lags. To test how temporal selection affects spatial selection in Experiments 2 and 3, response congruent and incongruent flankers were introduced beside T2 to determine if congruency effects change with lag. This was not observed, suggesting that spatial and temporal attention mechanisms may be separable.

摘要

空间注意力分散过程受空间注意力的可用性影响。当考虑响应选择时，尚不清楚的是时间选择在多大程度上改变了这种空间选择。注意眨眼（AB）范式非常适合研究此问题。在这项研究中，我们调整了AB任务以测量响应时间。在实验1中，参与者确定了两个目标（T1和T2），其中T2在T1之后以不同的滞后出现。据说只有在某些滞后内出现T2时，时间选择才会选择干扰因素。证实这一点，发现AB效应在短时滞下对T2的响应较慢。为了测试时间选择​​如何影响实验2和3中的空间选择，在T2旁边引入了响应一致和不一致的侧翼，以确定一致性效应是否随滞后而变化。
