The present research examined the possibility that repeated exposure may si
multaneously produce specific and diffuse effects. bt Study 1, participants
were presented with 5-ms exposures of 25 stimuli each shown once (single-e
xposure condition) or with five repetitions of 5 stimuli (repeated-exposure
condition). Participants ill the repented-exposure condition subsequently
rated their own mood more positively than those in the single-exposure cond
ition. Study 2 examined whether affect generated by subliminal repented exp
osures transfers to unrelated stimuli. After a subliminal exposure phase, a
ffective reactions to previously exposed stimuli, to new but similar stimul
i, and to stimuli from a different category were obtained Previously expose
d stimuli were rated most positively and novel different stimuli least posi
tively. All stimuli were rated more positively in the repeated-exposure con
dition than in the single-exposure condition. These findings suggest that a
ffect generated by subliminal repeated exposure is sufficiently diffuse to
influence ratings of unrelated stimuli and mood.
