A pre-publication copy of 'Shape, perspective, and what is and is not perceived', soon to appear in Psychological Review, is now posted on psyArXiv. The article makes a number of pointed criticisms of Morales et al. (2020), 'Sustained representation of perspectival shape' PNAS. The article also makes multiple positive contributions. These include discussion of: i) the nature of explanation in perception science, ii) the 'dual character' of visual perception, iii) the distinctions between neural and perceptual representation, and iv) the importance of clearly distinguishing between sensation, perception, and conscious awarenesses associated with sensation and/or perception.

Paper posted by Daniel Herrera on the optimal computations for estimating motion-in-depth from natural image movies. The paper contains a beautiful set of results including, but not limited to, the spontaneous emergence of two distinct receptive field populations with functional specializations for estimating the two primary binocular cues to 3D motion: interocular velocity difference signals (IOVD)--best at fast speeds--, and changing disparity over time signals (CDOT)--best at slow speeds.

Paper posted on human stereo-depth discrimination in natural scenes. The research makes use of a high-fidelity stereo-image database of natural scenes with pixel-by-pixel laser-based distance data, two enormous double-pass experiments utilizing a within-subjects design, and a novel analytical method to determine the distinct sources of uncertainty in natural images and scenes that limit the percision of human stereo-depth perception in natural viewing.

New paper posted. Feature-specific (or tuned) normalization improves stimulus encoding for stereo-depth perception. We derive and apply new expressions for the Fisher information about binocular disparity in receptive field population responses to natural scenes. And we quantify the advantage of tuned over un-tuned normalization. The analysis establishes a new functional role for tuned divisive normalization in latent variable encoding / decoding in natural scenes. Congrats Long!
