三个实验检验了已知会破坏面部感知的图像处理是否也会破坏视觉语言感知。研究表明，一张嘴巴倒着的直立脸看起来非常怪异，而一张倒立的脸和一张嘴巴倒着的倒立脸看起来相对正常。目前的研究考察了对直立面部环境的类似敏感性是否在视觉语言感知中起作用。在4种呈现条件下测试视觉和视听音节识别任务：直立脸-直立嘴、倒立脸-倒立嘴、倒立脸-直立嘴和直立脸-倒立嘴。结果表明，对于某些视觉音节，只有直立的脸-倒嘴图像会干扰识别。这些结果表明，直立的面部环境可以在视觉语音感知中发挥作用。一项后续实验测试了孤立的嘴巴，支持了这一结论。
Three experiments examined whether image manipulations known to disrupt face perception also disrupt visual speech perception. Research has shown that an upright face with an inverted mouth looks strikingly grotesque whereas an inverted face and an inverted face containing an upright mouth look relatively normal. The current study examined whether a similar sensitivity to upright facial context plays a role in visual speech perception. Visual and audiovisual syllable identification tasks were tested under 4 presentation conditions: upright face-upright mouth, inverted face-inverted mouth, inverted face-upright mouth, and upright face-inverted mouth. Results revealed that for some visual syllables only the upright face-inverted mouth image disrupted identification. These results suggest that upright facial context can play a role in visual speech perception. A follow-up experiment testing isolated mouths supported this conclusion.
