Biography

Leslie Welch is an Associate Professor in the Cognitive Psychological Sciences at Brown University. His research focuses on visual information processing, specifically investigating the available information in parts of the visual system and how that information is utilized. Welch conducts psychophysical experiments with adult human observers trained to perform tasks with feedback to enhance learning, comparing performance across different tasks to assess the specific discrimination and detection of information used. A significant aspect of his research involves understanding the perception of speed and direction of moving objects, aiming to discover the limitations of the motion perception system and how relative position and depth influence observers' visual experiences. Welch collaborates with a wide community of visual system scientists in psychophysics, physiology, and computational modeling, working to uncover the mechanisms the brain employs to resolve perceptual challenges.
