“…Some studies have showed that perceptual reversal rate is influenced by various factors like figure size (Washburn et al 1931; Goldhamer 1934; Spitz and Lipman 1962), luminance (Mull et al 1954, 1956; Heath et al 1963), and room temperature (Heath et al 1963). These studies provided evidence for that reversals occur during primary visual processing, but other studies supported that reversals occur during higher-level processing (for a review, see Long and Toppino 2004).…”

How intermittent presentation affects conscious perceptual reversals of ambiguous figures

Continually observing an ambiguous figure, we can perceive reversals between different interpretations. How perceptual reversals change when an ambiguous stimulus is presented intermittently? Since no reversal can be consciously perceived during off-periods, we use net Average Reversal Interval (netARI) but not usual average reversal interval to measure the perceptual reversal rate. NetARI is calculated by dividing accumulated time of on-periods by the number of reversals. The results are: (1) presenting an ambiguous figure intermittently increased the perceptual reversal rate; (2) the longer the exposure of Necker cube, the slower the perceptual reversal rate was, and when on-periods were longer as 15 s, the perceptual reversal rate was slowed down and was almost same to that in the continuous case; (3) the length of off-periods (which ranged from 1 s to 5 s in the present study) did not affect the reversal rate.

“…The level of illumination is seldom reported in reversiblefigure experiments, and there is no clear-cut evidence of its effect on the results. Mull, Ord, & Locke (1954) and Mull, Armstrong, & Telfer (1956) found no relationship between illumination and reversals of the Necker Cube and Kohler Cross, respectively, while Cipywnyk (1959) found reversal rate to be an increasing function of illumination level in a study with the Necker Cube. However, it is difficult to compare the results of even these experiments in any direct way.…”

“…Generally, results are presented in the form of mean number of reversals per trial, although some workers have preferred alternative measures. Brown (1955) tested Ss for 10 trials of 30 sec duration, and compared the mean total number of reversals for each S. Mull, Ord, & Locke (1954) recorded the mean time to observe 10 reversals over 20 trials. In a study with a three-dimensional skeletal cube, Adams (1954) recorded the latency of the first reversal.…”

The lack of an adequate theory of reversible perspective is largely attributable to the haphazard methodology adopted by many workers in this area of research. After more than 60 years. no standard experimental procedure has evolved, and the comparison of results from different studies is difficult. Some representative experiments are reviewed in terms of the temporal, stimulus, and procedural factors involved. It is suggested that the general use of the reversal rate measure is the major single barrier to progress. and that a continuous recordingmethod be adopted in future experimentation.

“…Empirical research on the figure reversal phenomenon has concentrated primarily upon the establishment of psychophysical relationships. Several stimulus variables have been studied extensively, including luminance (Mull, Ord & Locke, 1954;Mull, Armstrong & Telfer, 1956;Chipywynk, 1959;Howard, 1961;Lynn, 1961;, size of the figure (Washburn, Mallay & Naylor, 1931;Dugger & Courson, 1968), and observation time (Brown, 1955(Brown, , 1962Cohen, 1959; Spitz & Lipman, 1962;Price, 1967).…”

Enhancement of Figure Reversal Rate in Intermittent Light

Magnussen S. Enhancement of figure reversal rate in intermittent light. Scand. J. Psychol., 1972, 13, 61–65.—The reversal rate of an ambiguous visual figure viewed in intermittent light increased with rate of intermittency up to a culminating point, whereafter it gradually fell off to the base level (steady light). The similarity between these results and the Brücke‐Bartley effect (enhancement of apparent brightness at lower flicker rates) is pointed out, and the possibility of a common physiological basis for the two phenomena is suggested.
