Ocularity and adaptation in a depth discrimination task

1 May 1994


Depth perception and adaptation, as related to ocularity, are the topics of this experimental study. Subject samples consist of three groups- one binocular, one composed of unilaterally occluded binocular subjects, and one composed of two adapted monocular patients (one eye enucleated). Both speed and accuracy were measured using a modified Howard Dolman apparatus. Binocular individuals demonstrated significantly better performance than occluded binocular subjects in both accuracy and a measure of JND. There was no significant difference in speed of judgment between groups. Due to the small sample of adapted monocular subjects and their variable performance, no generalizations can be drawn from their results. Individual results are discussed as are implications for further research.
