Test of competing explanations of the bizarre response bias in recognition memory.
Recent research has demonstrated that a more liberal response criterion is used when people make judgments about bizarre items than about common items in old-new tests of recognition. The present study was designed to test 2 possible explanations of the bizarre response bias. The bizarre-relations explanation suggests that the bizarre response bias is triggered by the bizarre relations depicted in test items. The target-constituent explanation suggests that the bizarre response bias is the result of a sense of familiarity with constituents of bizarre test items. These explanations were tested by examining the influence of lure manipulations on memory discrimination and response bias for common and bizarre hand-drawn pictures. The results indicated support for the target-constituent explanation by reversing the response bias (obtaining a common response bias) in a recognition test that used common lures containing constituents from bizarre target items and bizarre lures containing constituents from common target items. The results also indicated that increased verbal elaboration enhanced memory discrimination and reduced response bias for both common and bizarre stimuli. The implications of these results are discussed with regard to the false memory controversy.
