Sudden onset of subjective dimensionality: a case study.
For 45 years, Bob had no subjective sense of depth; the world appeared two-dimensional to him. Then, when he was viewing mountain vistas while using marijuana, he suddenly was able to see three dimensions. This case, apparently unique in the literature, suggests that subjective dimensionality may be functionally separate from use of distance cues.
