Abstract:

Using the method of pair comparisons, subjects judged 12 stimulus configurations comprised of horizontal Mueller-Lyer M-L figures bordered above and below by shorter or longer anchoring lines. From the pooling model of adaptation-level theory, it was predicted that perceived length of the M-L figures would be assimilated toward anchor length. Results confirmed the prediction. Author
