Border ownership-dependent tilt aftereffect for shape defined by binocular disparity and motion parallax.
Discerning objects from their surrounds (i.e., figure-ground segmentation) in a way that guides adaptive behaviors is a fundamental task of the brain. Neurophysiological work has revealed a class of cells in the macaque visual...
Explaining temporal qualia
Matt Farr
Jan 08, 2021
Abstract: Experiences of motion and change are widely taken to have a ‘flow-like’ quality. Call this ‘temporal qualia’. Temporal qualia are commonly thought to be central to the question of whether time objectively passes: (1)...
Separation in the visual field has divergent effects on discriminating the speed and the direction of motion.
Local motion in a visual scene allows the detection of prey or predator and predicts their future positions. Relative motion segregates objects and reveals their 3D relationships. 'Optic flow' - the motion of texture across the...
Counterfactual Reasoning Underlies the Learning of Priors in Decision Making.
Accurate decisions require knowledge of prior probabilities (e.g., prevalence or base rate), but it is unclear how prior probabilities are learned in the absence of a teacher. We hypothesized that humans could learn base rates...
Dissociation between perception and smooth pursuit eye movements in speed judgments of moving Gabor targets.
Anna E Hughes
Apr 23, 2018
The relationship between eye movements and subjective perception is still relatively poorly understood. In this study, participants tracked the movement of a Gabor patch and made perceptual judgments of its speed using a...
Multiple decisions about one object involve parallel sensory acquisition but time-multiplexed evidence incorporation.

The brain is capable of processing several streams of information that bear on different aspects of the same problem. Here, we address the problem of making two decisions about one object, by studying difficult perceptual...
Structural connectome and connectivity lateralization of the multimodal vestibular cortical network.

Unlike other sensory systems, the structural connectivity patterns of the human vestibular cortex remain a matter of debate. Based on their functional properties and hypothesized centrality within the vestibular network, the...

But Still It Moves
Seeing movement promotes survival. It results from an uncertain interplay between evolution and experience, making it hard to isolate the drivers of computational architectures found in brains. Here we seek insight into motion...
How multisensory neurons solve causal inference.
Sitting in a static railway carriage can produce illusory self-motion if the train on an adjoining track moves off. While our visual system registers motion, vestibular signals indicate that we are stationary. The brain is faced...
Mechanisms for extracting a signal from noise as revealed through the specificity and generality of task training.
Visual judgments critically depend on (1) the detection of meaningful items from cluttered backgrounds and (2) the discrimination of an item from highly similar alternatives. Learning and experience are known to facilitate these...
