Attribute amnesia (Chen & Wyble, 2015, 2016) demonstrates that we may not always be able to spontaneously retrieve a simple attribute of a visual object (e.g., its color) for conscious report, even though the object had just been the target in a visual task. Attribute amnesia has been suggested to reflect a lack of consolidation of the task-irrelevant attribute in visual working memory. Here we tested whether saccadic selection eliminates or attenuates attribute amnesia. Saccade targets have been shown to be preferentially encoded into visual working memory and may therefore be spared. We used simple color pop-out displays, asking participants to indicate the location of the color singleton letter target on each trial either by keypress or by making a saccade toward it. After a couple of trials and unannounced to the participants, we asked for the color and identity of the last target letter on a surprise trial. We found that saccade targets were not spared from attribute amnesia: Participants were as bad in correctly reporting the color in the saccade as in the keypress condition. For letter identity, the effect was attenuated but not abolished when the target was foveated for a short period of time. We argue that the current results do not refute an obligatory coupling between saccadic selection and encoding in visual working memory. However, the encoded information may not necessarily be stored in a manner that is robust enough to persist in the face of a surprise question.

属性遗忘(Chen & Wyble,2015,2016)表明,我们可能并不总是能够自发地回忆起视觉对象的简单属性(例如,其颜色)以供有意识地报告,即使该对象刚刚是视觉任务的目标。属性遗忘被认为反映了视觉工作记忆中与任务无关的属性的巩固不足。在这里,我们测试了眼跳选择是否消除或减轻了属性遗忘。眼跳目标已经被证明优先被编码到视觉工作记忆中,因此可能会被保留。我们使用简单的颜色弹出显示,要求参与者在每次试验中通过按键或向其进行眼跳来指示颜色单字母目标的位置。在几次试验后,我们在参与者不知情的情况下,在一个惊喜试验中询问最后一个目标字母的颜色和身份。我们发现,眼跳目标并没有免受属性遗忘的影响:参与者在正确报告眼跳条件下的颜色方面与按键条件一样糟糕。对于字母身份,当目标在短时间内被注视时,该效应被减弱但没有被消除。我们认为,当前的结果并没有反驳眼跳选择与视觉工作记忆中的编码之间的强制性耦合。然而,编码的信息可能不一定以足够稳健的方式存储,以在面对惊喜问题时保持不变。(PsycINFO 数据库记录(c)2019 APA,保留所有权利)。
