When dissimilar figures are presented to the two eyes individually, perception alternates spontaneously between each monocular view. This phenomenon, designated binocular rivalry, has been used by many scientists as a tool for investigating visual awareness. Some recent studies have suggested involvement of serotonergic neural systems in this phenomenon. We explored the relationship between binocular rivalry and anxiety, a state thought to be associated with serotonergic neural activity. Perceptual alternation rate in dominance of binocular rivalry were compared between normal volunteers with high and low general anxiety as measured using the harm avoidance (HA) scale of the Tridimensional Personality Questionnaire. Perceptual alternation rate and rhythmicity in the high-HA group was significantly greater than that in the low-HA group. The perceptual alternation rate in binocular rivalry was accelerated in anxious subjects, suggesting that binocular rivalry and anxiety may share some common serotonergic neural substrates.
当不同的图像分别呈现给两只眼睛时，感知会在每个单眼视图之间自发交替。这种现象被称为双眼竞争，许多科学家已将其用作研究视觉意识的一种工具。最近的一些研究表明血清素能神经系统参与了这一现象。我们探究了双眼竞争与焦虑之间的关系，焦虑是一种被认为与血清素能神经活动相关的状态。使用三维人格问卷的回避伤害（HA）量表，比较了高一般性焦虑和低一般性焦虑的正常志愿者在双眼竞争优势中的感知交替率。高HA组的感知交替率和节律性显著高于低HA组。焦虑受试者的双眼竞争感知交替率加快，这表明双眼竞争和焦虑可能共享一些共同的血清素能神经基质。
