1. What is Perceptual Fluency? The study of Reber et al. (2004):Reber et al. (2004) Perceptual fluency is the subjective experience of ease with which an incoming stimulus is processed; it is a kind of processing fluency. It has been shown to influence different kinds of judgments, such as affective judgments (Reber et al., 1998) or judgments of truth (McGlone & Tofighbakhsh, 2000; Reber & Schwarz, 1999)processing fluencyjudgmentsReber et al., 1998McGlone & Tofighbakhsh, 2000 Reber & Schwarz, 1999 Contributor© POSbase 2004

2. What is Perceptual Fluency? © POSbase 2004 The question arises how perceptual fluency is related to objective processing speed. One hypothesis is that speed at different perceptual stages contribute jointly to the subjective experience of ease of processing.

3. What is Perceptual Fluency? In an experiment, the authors showed words that were written (1) in high versus low figure-ground contrast; (2) in a well-readable versus a moderately readable font (Times versus Tremor). There were three groups of participants who solved different tasks: (1) Judgment of ease with which a word could be perceived; (2) Detection of masked words (early stage in perception); (3) Identification of words (later stage in perception). © POSbase 2004

4. What is Perceptual Fluency? The results supported the notion that speed at different perceptual stages contribute jointly to the subjective experience of ease of processing: © POSbase 2004  Both contrast and font contributed to the judged ease of perception. Figure ground contrast and font yielded a double dissociation:double dissociation  Figure-ground contrast influenced detection performance, but not identification performance.  Font influenced identification performance, but not detection performance.
