Persistent Biases in Binocular Rivalry Dynamics within the Visual Field

摘要: Binocular rivalry is an important tool for measuring sensory eye dominance—the relative strength of processing in individual’s left and right eye. By dichoptically presenting images that lack corresponding visual features, one can induce perceptual alternations measure the visibility each eye’s image. Previous results indicate observers demonstrate reliable preferences several image these biases vary within field. However, evidence about persistence mixed, with some suggesting they affect only onset (i.e., first second) rivalry, others lasting effects during prolonged viewing. We directly investigated individuals’ color field interestingly found mirrored somewhat contradictory pattern literature. Each observer demonstrated idiosyncratic patterns both field, but consistent, presentation (sensory dominance, SED). Furthermore, predicted one’s performance on a stereoacuity task. This finding supports idea binocular other functions may rely shared mechanisms, emphasizes importance SED as vision.
