Abstract

Four bluejays received 700 problems of object-discrimination learning set. Acquisition of the task was shown by an average performance level of 72% correct for Trial 2 on the last 100 problems of the experiment. This figure is superior to asymptotic Trial 2 levels for many subprimate mammalian species and comparable to the marmoset (Warren, 1965). A detailed analysis of the data for “hypothesis behavior” (Levine, 1965) revealed several important features of the Ss’ responding, many of potential comparative significance. In particular, consistent decreases in responding due to stimulus preferences and third trial learning, a dramatic drop in random responding, and steady increases in WSLS-object (maximum strategy) coincided with increasing proficiency.
