ABSTRACT

Recent research on change blindness phenomenon revealed contradictory findings about scene-object relationship. These discrepant results might be stemming from procedure and task constraints. Therefore, we aimed to investigate the effect of the type of paradigm on change blindness phenomenon during the natural scene viewing in the frame of high-level scene perception. For this purpose, we compared two frequently used change detection tasks; flicker and one-shot paradigms. Additionally, eye movements were recorded to investigate the active attention mechanisms during the change detection performance. Our results suggested that change detection performance and eye movements varied across the different paradigms. We interpreted this result as the influence of different stimuli exposures and different interruptions on processing of visual stimuli during the detection of change. We explained the inconsistent results revealed by the previous research in terms of attention mechanisms, namely attention attraction and attention disengagement that might differ while performing the different change detection tasks.

摘要

最近对变化盲目现象的研究揭示了关于场景-对象关系的矛盾发现。这些不一致的结果可能源于程序和任务限制。因此，我们旨在研究范式类型对高级场景感知框架中自然场景观看过程中变化盲视现象的影响。为此，我们比较了两个常用的变更检测任务；闪烁和一次性范式。此外，记录眼球运动以研究变化检测性能期间的主动注意机制。我们的结果表明，变化检测性能和眼球运动在不同的范式中有所不同。我们将此结果解释为不同刺激暴露和不同中断对变化检测过程中视觉刺激处理的影响。我们从注意力机制的角度解释了先前研究揭示的不一致结果，即在执行不同的变化检测任务时可能会有所不同的注意力吸引和注意力脱离。
