Description: Results of an experiment on the effect of prior information on the time to fuse random dot steregrams. One group (NV) was given either no information or just verbal information about the shape of the embedded object. A second group (group VV) received both verbal information and visual information (e.g., a drawing of the object).
Number of cases: 81
Variable Names:
  1. Time: Time to produce a fused image of the random dot steregram
  2. Group: Treatment group (NV or VV)
