Neglect patients are not aware of stimuli in the contralesional space. We aimed to simulate neglect-like behaviour in healthy participants, by asking them to orient their visuospatial attention in two conditions: non-hypnotic suggestion and post-hypnotic suggestion. Results showed that directing visuospatial attention to one side of space caused neglect of stimuli in the opposite side of space, but only when participants were under post-hypnotic suggestion. Furthermore, directing visuospatial attention to the right side of space caused more neglect of left-sided stimuli than directing visuospatial attention to the left side of space did for right-sided stimuli. We propose that post-hypnotic suggestion can be a useful tool for (de)activating neurocognitive mechanisms underlying visuospatial awareness, a function that is fundamental for our survival. The use of post-hypnotic suggestion could be applied to the study of many domains of cognitive neurosciences (e.g., neurocognitive rehabilitation).
忽略症患者无法感知对侧空间中的刺激。我们旨在通过让健康参与者在两种条件下将其视空间注意力转向来模拟忽略症行为：非催眠暗示和催眠后暗示。结果表明，将视空间注意力引导到空间的一侧会导致对另一侧空间刺激的忽略，但仅在参与者处于催眠后暗示时才会发生这种情况。此外，将视空间注意力引导到右侧空间会导致对左侧刺激的忽略程度大于将视空间注意力引导到左侧空间对右侧刺激的忽略程度。我们提出，催眠后暗示可以成为（激活/去激活）与视空间意识相关的神经认知机制的有用工具，而视空间意识是我们生存的基本功能。催眠后暗示的使用可以应用于认知神经科学的许多领域的研究（例如，神经认知康复）。
