Color name as a function of surround luminance and stimulus duration

A color-naming experiment was performed in which both surround luminance and exposure duration were varied. The data showed substantial effects from these changes; however, none could be interpreted to indicate the presence of a Bezold-Brucke shift or tritanopia.     

Discrimination of checkerboard patterns by rats

Fifteen rats were trained to discriminate between a regular checkerboard pattern and a similar pattern containing a “mistake.” The animals subsequently transferred to many other pairs of regular and irregular patterns differing widely from the originals. The results suggest that rats can induce and store highly abstract rules describing input patterns.
