In perceptual rivalry, ambiguous sensory information leads to dynamic changes in the perceptual interpretation of fixed stimuli. This phenomenon occurs when participants receive sensory stimuli that support two or more distinct interpretations; this results in spontaneous alternations between possible perceptual interpretations. Perceptual rivalry has been widely studied across different sensory modalities including vision, audition, and to a limited extent, in the tactile domain. Common features of perceptual rivalry across various ambiguous visual and auditory paradigms characterize the randomness of switching times and their dependence on input strength manipulations (Levelt’s propositions). It is still unclear whether the general characteristics of perceptual rivalry are preserved with tactile stimuli. This study aims to introduce a simple tactile stimulus capable of generating perceptual rivalry and explores whether general features of perceptual rivalry from other modalities extend to the tactile domain. Our results confirm that Levelt’s proposition II extends to tactile bistability, and that the stochastic characteristics of irregular perceptual alternations agree with non-tactile modalities. An analysis of correlations between subsequent perceptual phases reveals a significant positive correlation at lag 1 (as found in visual bistability), and a negative correlation for lag 2 (in contrast with visual bistability).

与振动触觉刺激的知觉竞争

在知觉竞争中,模糊的感官信息会导致对固定刺激的知觉解释发生动态变化。当参与者收到支持两种或多种不同解释的感觉刺激时,就会出现这种现象;这导致可能的感知解释之间的自发交替。感知竞争已在不同的感官模式中得到广泛研究,包括视觉、听觉,并在有限的范围内,在触觉领域。跨越各种模糊的视觉和听觉范式的感知竞争的共同特征表征了切换时间的随机性及其对输入强度操作的依赖(Levelt 的命题)。目前尚不清楚触觉刺激是否保留了知觉竞争的一般特征。本研究旨在引入一种能够产生知觉竞争的简单触觉刺激,并探讨其他方式的知觉竞争的一般特征是否延伸到触觉领域。我们的结果证实,Levelt 的命题 II 扩展到触觉双稳态,并且不规则感知交替的随机特征与非触觉模态一致。对后续感知阶段之间相关性的分析显示,在滞后 1 处显着正相关(如在视觉双稳态中发现的那样),在滞后 2 处呈负相关(与视觉双稳态相反)。我们的结果证实,Levelt 的命题 II 扩展到触觉双稳态,并且不规则感知交替的随机特征与非触觉模态一致。对后续感知阶段之间相关性的分析显示,在滞后 1 处显着正相关(如在视觉双稳态中发现的那样),在滞后 2 处呈负相关(与视觉双稳态相反)。我们的结果证实,Levelt 的命题 II 扩展到触觉双稳态,并且不规则感知交替的随机特征与非触觉模态一致。对后续感知阶段之间相关性的分析显示,在滞后 1 处显着正相关(如在视觉双稳态中发现的那样),在滞后 2 处呈负相关(与视觉双稳态相反)。
