Abstract

Our two eyes receive different views of a visual scene, and the resulting binocular disparities enable us to reconstruct its three-dimensional layout. However, the visual environment is also rich in monocular depth cues. We examined the resulting percept when observers view a scene in which there are large conflicts between the surface slant signaled by binocular disparities and the slant signaled by monocular perspective. For a range of disparity–perspective cue conflicts, many observers experience bistability: They are able to perceive two distinct slants and to flip between the two percepts in a controlled way. We present a Bayesian model that describes the quantitative aspects of perceived slant on the basis of the likelihoods of both perspective and disparity slant information combined with prior assumptions about the shape and orientation of objects in the scene. Our Bayesian approach can be regarded as an overarching framework that allows researchers to study all cue integration aspects—including perceptual decisions—in a unified manner.

  25. Although eye movements play a role, the perceptual bistability seems to be predominantly central. We are currently measuring eye movements while subjects experience bistability in our grid stimuli. Our preliminary findings reveal that switching between the two percepts can occur by effort of will while subjects keep strict fixation. When eye movements are allowed, there is no clear correlation between perceptual flips and both eye movements and blinks.26

  29. A sensible objection to this metrical slant-estimation method is that it is hard to interpret the data because a slant angle that is estimated at 35 deg in one trial might look like 40 deg in another trial. Previous work has demonstrated, however, that subjects have a relatively constant internal reference and that they do not regard this task as difficult. This estimation method has been used previously for real planes10and when subjects wore distorting lenses.30In addition, a similar metrical depth-estimation method was successfully used for volumetric stimuli.31

  55. It is of historical interest to note that Bayes died in 1761 and that an essay that Bayes wrote had been published by the Royal Society56two years after his death. Bayes’s theorem was originally developed to model human conscious judgments during the playing of games, but it has proven to be wrong for this purpose.37In modern vision science, Bayes’s work has been attached to the following equation: p(S|I)∝p(I|S)p(S).It therefore comes as a surprise that this equation is not present in Bayes’s essay. According to Dale,57Laplace’s58formulations have mistakenly been applied as those of Bayes. This is not to say that Bayes does not deserve the name for the theory.

  59. To decide which of the peaks corresponds to the weak rectangularity mode and which of the peaks corresponds to the strong rectangularity mode, we compared the peaks in the expected gain distribution with the highest peaks in the individual posterior distributions. It is relatively straightforward to shift the bifurcation point by applying a different gain function, producing bifurcation points that perfectly fit the obtained data. However, the coefficient goodness of fit that we generally applied (see Table 1) becomes then slightly worse relative to the best fit of the model.
