Becoming famous overnight: Limits on the ability to avoid unconscious influences of the past.

Nonfamous names presented once in an experiment are mistakenly judged as famous 24 hr later. On an immediate test, no such false fame occurs. This phenomenon parallels the sleeper effect found in studies of persuasion. People may escape the unconscious effects of misleading information by recollecting its source, raising the criterion level of familiarity required for judgments of fame, or by changing from familiarity to a more analytic basis for judgment. These strategies place constraints on the likelihood of sleeper effects. We discuss these results as the unconscious use of the past as a tool vs its conscious use as an object of reflection. Conscious recollection of the source of information does not always occur spontaneously when information is used as a tool in judgment. Rather, conscious recollection is a separate act.

Becoming famous without being recognized: Unconscious influences of memory produced by dividing attention.

The familiarity of names produced by their prior presentation can be misinterprete d as fame. We used this false fame effect to separately study the effects of divided attention on familiarity versus conscious recollection. In a first experiment, famous and nonfamous names were presented to be read under conditions of full vs. divided attention. Divided attention greatly reduced later recognition memory performance but had no effect on gains in familiarity as measured by fame judgments. In later experiments, we placed recognition memory and familiarity in opposition by presenting only nonfamous names to be read in the first phase. Recognizing a name as earlier read on the later fame test allowed Ss to be certain that it was nonfamous. Divided attention at study or during the fame test reduced list recognition performance but had no effect on familiarity. We conclude that conscious recollection is an attention-demanding act that is separate from assessing familiarity. Folk wisdom suggests that we benefit from experience by consciously remembering those experiences and applying the knowledge gained from them to the current situation. In contrast, research shows that many effects of prior experience on later performance can occur independently of the ability to consciously recollect the experience (see Richardson-Klavehn & Bjork, 1988, for a review). In this article, we provide further evidence that the past can be used to influence present performance without the intervention of conscious recollection. We show that divided attention, in comparison with full attention, can radically reduce a person's ability to recognize an item as previously presented while leaving intact the effects of that prior presentation on judgment. Furthermore, this potential for unconscious influence of the past leads to a role for conscious recollection that is directly counter to that advanced by folk wisdom. Rather than being a prerequisite for producing effects of the past, conscious recollection can be a means of escaping misleading effects of the past. The task that we used required subjects to judge whether a name was famous. In the first phase of each experiment, people read a list of names. Then those old names were mixed with new famous and new nonfamous names in a test of fame
