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).
