In Exp. I, 20 Ss trained to finger lift to a light of 490 mMU (labeled "green" by E) responded more in generalization testing to longer ("greener") and less to shorter ("bluer") wavelengths than 20 Ss told that it was "blue." In Exp. II, 77 Ss were trained to finger lift to 490 mMU, as in Exp. I, except that Ss were 1st told that "a group of college Ss in a previous experiment" had judged the CS "mostly green," and they were required to state their level of agreement with the group judgment. The greater their stated level of agreement with the mostly green label, the greater was their subsequent tendency to respond to longer ("greener") wavelengths during generalization testing.
