Previous research has suggested that repeated exposure to novel stimuli produces changes in their connotative meaning, but that some delay may be required for this effect. Thirty-six undergraduates viewed nonsense syllables in various frequencies, then rated them for pleasantness following no delay (Condition 1) or following a delay which provided cognitive activity presumably facilitating or inhibiting rehearsal (Conditions 2 and 3). In all three conditions, both judged pleasantness and recall were a linear increasing function of log exposure frequency; no main effect of condition nor interaction of Condition by Frequency was found. The results suggest a rating delay may not always be needed for “mere exposure” effects. |
