In Experiment 1 (change blindness), participants received either intermixed or blocked presentations of two visual stimuli that contained several common (X) and unique (A or B) features. On the critical trial after exposure, the stimulus AX was presented but included an unexpected visual event (a change in the size of a stimulus feature). We found that participants readily detected the change when it involved an A-unique feature that had been preexposed intermixed. However, if the change involved an A-unique feature preexposed in blocks, or an X-common feature (preexposed either intermixed or in blocks), the level of the detections considerably decreased. In Experiment 2, after either intermixed or blocked preexposure to AX and BX, all the participants were instructed to search for an unrelated visual target item. In the distractor condition, during the development of the search task, the A-unique feature emerged at an unpredictable location that was different to that occupied by this feature during the preexposure. In the control condition, the target was presented on its own during the entire task. The presence of the A-unique feature only produced a detrimental effect on search performance when the AX and BX had been preexposed intermixed. These results are discussed as indicative of the intermixed preexposure schedule enhancing the ability of the stimulus unique features to capture involuntary attention.

重新考虑刺激独特特征吸引注意力的能力:来自变化盲目性和视觉搜索范式的证据。

在实验 1(变化失明)中,参与者收到两种视觉刺激的混合或屏蔽演示,其中包含几个常见的 (X) 和独特的 (A 或 B) 特征。在暴露后的关键试验中,呈现刺激 AX 但包括意外的视觉事件(刺激特征大小的变化)。我们发现,当涉及预先混合的 A 级独特特征时,参与者很容易发现这种变化。但是,如果更改涉及在块中预曝光的 A 独特特征,或 X 共同特征(混合或在块中预曝光),则检测水平会显着降低。在实验 2 中,在对 AX 和 BX 进行混合或阻止预暴露后,所有参与者都被要求搜索一个不相关的视觉目标项目。在干扰条件下,在搜索任务的开发过程中,A-unique 特征出现在一个不可预测的位置,与预曝光期间该特征所占据的位置不同。在控制条件下,目标在整个任务中单独呈现。当 AX 和 BX 被预混合预曝光时,A-unique 特征的存在只会对搜索性能产生不利影响。这些结果被讨论为混合暴露前时间表的指示,增强了刺激独特特征捕捉非自愿注意力的能力。(PsycInfo 数据库记录 (c) 2021 APA,保留所有权利)。在整个任务期间,目标是单独呈现的。当 AX 和 BX 被预混合时,A-unique 特征的存在只会对搜索性能产生不利影响。这些结果被讨论为混合暴露前时间表的指示,增强了刺激独特特征捕捉非自愿注意力的能力。(PsycInfo 数据库记录 (c) 2021 APA,保留所有权利)。在整个任务期间,目标是单独呈现的。当 AX 和 BX 被预混合时,A-unique 特征的存在只会对搜索性能产生不利影响。这些结果被讨论为混合暴露前时间表的指示,增强了刺激独特特征捕捉非自愿注意力的能力。(PsycInfo 数据库记录 (c) 2021 APA,保留所有权利)。
