通常，视觉系统对世界提供了一种明确的表示。然而，有时会出现对给定刺激的另一种似是而非的解释，导致不同解释的动态感知交替，通常被称为双稳态或竞争性感知。最近的研究表明，共同的神经机制可能涉及到非常不同类型的双稳现象的动力学。此外，有证据表明，遗传因素可能参与了决定至少一种形式的双稳态知觉的转换速度，即所谓的双眼竞争。目前的研究评估了遗传因素是否对同一参与者样本中明显不同的双稳态知觉变体的转换动力学起到了作用。MZ和DZ双胞胎参与者在两种不同的双稳态知觉任务--双眼竞争任务和Necker Cube任务中记录了转换率。对于MZ双胞胎和DZ双胞胎来说，两个任务的切换率之间的强烈一致性是显而易见的，这表明遗传因素确实有助于多种形式的双稳态知觉的动态变化。
Ordinarily, the visual system provides an unambiguous representation of the world. However, at times alternative plausible interpretations of a given stimulus arise, resulting in a dynamic perceptual alternation of the differing interpretations, commonly referred to as bistable or rivalrous perception. Recent research suggests that common neural mechanisms may be involved in the dynamics of very different types of bistable phenomena. Further, evidence has emerged that genetic factors may be involved in determining the rate of switch for at least one form of bistable perception, known as binocular rivalry. The current study evaluated whether genetic factors contribute to the switching dynamics for distinctly different variants of bistable perception in the same participant sample. Switching rates were recorded for MZ and DZ twin participants in two different bistable perception tasks, binocular rivalry and the Necker Cube. Strong concordance in switching rates across both tasks was evident for MZ but not DZ twins, indicating that genetic factors indeed contribute to the dynamics of multiple forms of bistable perception.
