stereogram: Stereogram fusion

In fastR: Foundations and Applications of Statistics Using R

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).

Format

A data frame with 78 observations on the following 2 variables.

• Time time until subject was able to fuse a random dot stereogram

• Group treatment group: NV(no visual instructions) VV (visual instructions)
