Abstract
The pigeon''s threshold for discrimination of lines was at approximately 23 to 29 seconds. Even with the lines subtending large visual angles, however, discrimination was never consistent. Human subjects tested under similar conditions possessed an acuity about half that of the pigeons.This publication has 2 references indexed in Scilit:
