Recent neuropsychological literature has provided evidence for the phenomenon of perception without awareness, also referred to as covert (or implicit) knowledge or tacit awareness. Yet little is known to date about the fate of extinguished stimuli in patients with unilateral spatial neglect. Six right brain-damaged patients with USN and one control subject were presented with single lateralized visual stimuli and with pairs of same or different visual stimuli (one right, one left). A same/different judgement and a multiple choice recognition task were performed on overtly unidentified left-sided stimuli, to unveil possible phenomena of covert knowledge. Some evidence of covert knowledge was observed, and its relation to stimulus characteristics and task demands is discussed.
最近的神经心理学文献为感知无觉察现象提供了证据,也称为隐性(或内隐)知识或隐性意识。然而,迄今为止,人们对单侧空间忽略患者中已消除刺激的命运知之甚少。6 名右脑损伤伴单侧空间忽略的患者和 1 名对照者被呈现单侧视觉刺激和相同或不同的视觉刺激对(一右,一左)。对未被识别的明显左侧刺激进行相同/不同判断和多项选择识别任务,以揭示可能的隐性知识现象。观察到一些隐性知识的证据,并讨论了其与刺激特征和任务要求的关系。
