The complex relationship between attention and visual perception can be exemplified and investigated through the Attentional Blink. The attentional blink is characterised by impaired attention to the second of two target stimuli, when both occur within 200 - 500ms. The attentional blink has been well studied in experimental lab settings. However, despite the rise of online methods for behavioural research, their suitability for studying the attentional blink has not been fully addressed yet, the main concern being the lack of control and timing variability for stimulus presentation. Here, we investigated the suitability of online testing for studying the attentional blink with visual objects. Our results show a clear attentional blink effect between 200 to 400ms following the distractor including a Lag 1 sparing effect in line with previous research despite significant inter-subject and timing variability. This work demonstrates the suitability of online methods for studying the attentional blink with visual objects, opening new avenues to explore its underlying processes.
注意与视觉感知之间的复杂关系可以通过注意瞬脱(Attentional Blink)来举例说明和研究。注意瞬脱的特征是,当两个目标刺激在 200-500ms 内出现时,第二个目标刺激的注意力会受到损害。注意瞬脱在实验实验室环境中得到了很好的研究。然而,尽管在线方法在行为研究中兴起,但它们是否适合研究注意瞬脱尚未得到充分解决,主要问题是刺激呈现的缺乏控制和时间可变性。在这里,我们研究了在线测试对于研究视觉对象的注意瞬脱的适用性。我们的结果表明,尽管存在显著的个体间和时间可变性,但在分心物之后 200 到 400ms 之间存在明显的注意瞬脱效应,包括与先前研究一致的滞后 1 保护效应。这项工作证明了在线方法对于研究视觉对象的注意瞬脱的适用性,为探索其潜在过程开辟了新的途径。
