I study human perception and action. The work uses a variety of methods including behavioral measurements, functional magnetic resonance imaging (fMRI) of brain activity, and computational models of the underlying behavior. The work centers on several different research areas.
- Sensory decision-making: I study how people set the criterion for a perceptual decision and estimate their confidence in that decision.
- Sensory cue integration: I'm interested in how people combine information from multiple sensory cues both within a sensory modality (e.g., multiple visual cues to depth) or across multiple sensory modalities (e.g., combining visual, tactile and/or auditory cues to stimulus location).
- Spatial vision and texture perception: I'm interested in how people represent and work with spatial pattern information to estimate local pattern orientation, detect the presence of boundaries between different regions, and how they adapt to scene statistics. I also study perception of natural texture properties such as roughness or gloss.
- Visually guided action: I have looked at how visual information is used to guide where you look and where you reach, and how these actions are guided by expectations, uncertain visual information and the costs and benefits of different movement outcomes.
- Depth perception: I have studied various visual cues to the 3-dimensional layout of the environment including binocular stereopsis (as in 3-d movies), motion parallax, texture perspective and lighting cues.
