Dissociable effects of attention and crowding on orientation averaging
TL;DR: It is concluded that crowding and attentional load have dissociable perceptual consequences for orientation averaging, suggesting distinct neural mechanisms for both.

Evidence for two interacting temporal channels in human visual processing.
John Cass,David Alais +1 more
TL;DR: A two-channel model is proposed in which a non-orientation-selective high-frequency channel suppresses an orientation-tuned low- frequencies channel, which may equalise the over-representation of low temporal-frequency energy in natural stimuli and contribute to motion deblurring.

Probabilistic, positional averaging predicts object-level crowding effects with letter-like stimuli.
TL;DR: A set of seemingly "high- level" object-centered crowding effects that can arise from "low-level" interactions between the features of letter-like elements are demonstrated.
Audiovisual temporal recalibration occurs independently at two different time scales
TL;DR: It is found that perceived simultaneity on a given trial was found to shift in the direction of the preceding trial’s asynchrony, and a dissociation is shown in which sustained adaptation produces a large but decaying recalibration effect whilst inter-trial recalIBration produces large transient effects whose sign matches that of the previous trial.
Dynamics of collinear contrast facilitation are consistent with long-range horizontal striate transmission
John Cass,Branka Spehar +1 more
TL;DR: It is demonstrated that the minimum exposure duration required to induce facilitation increases monotonically with greater target-flanker separation, and dynamics strongly suggest that contrast facilitation is mediated via long-range horizontal striate connections.
