Different case repetition still leads to perceptual blindness


, : Different case repetition still leads to perceptual blindness. Bulletin of the Psychonomic Society 26(1): 29-31

Jacoby and Dallas (1981) were the first to label the perceptual enhancement of a stimulus due to a prior presentation as "relative perceptual fluency." Our earlier work (Marohn and Hochhaus, in press) demonstrated that consecutive repetition priming and consecutive semantic priming have different effects on perceptual fluency, wherein repetition priming causes a phenomenon we call "perceptual blindness," in which the subject fails to perceive the second presentation. Is this failure simply a result of the exact physical repetition of the priming stimulus? The present epxeriment was a follow-up study designed to ascertain what effect a change in letter case format would have on the perceptual fluency of the repeated target word. Repetition in a different letter case showed that this "cognitive refractoriness" generalizes to different test conditions and goes beyond the physical features of the letters to the word as a whole unit.

RB was measured in rapid serial visual presentation (RSVP) streams, with th...
