Emotion Space as a Predictor of Binocular Rivalry

Abstract

In our 1999 report, we examined robustness of a two-dimensional structure of facial expressions of emotion under the condition of some perceptual ambiguity, using a stereoscope. The current study aimed to replicate and extend the previous work by adding facial photographs of different persons and by measuring participants' perception of stereoscopically presented faces. Multidimensional scaling provided a two-dimensional configuration of facial expressions comparable with the previous studies. Although binocular rivalry was a less frequent phenomenon, it was suggested that the distances between facial expressions in the derived space were a contributing factor in eliciting binocular rivalry.
