The Perception and Neuroimaging laboratory studies the neural mechanisms of perceptual decision making.
One focus is the basic neural mechanisms of object recognition. A greater understanding of the perceptual mechanisms underlying object recognition provides a foundation on which to study higher-level cognitive mechanisms. The PANLab also studies the influence of conceptual knowledge on decision making and the influence of perceptual factors on the planning and execution of environmentally appropriate actions. All of the research is conceived in a framework that stresses four premises. First, sensory systems do not function in isolation, but converge at relatively low levels of perceptual processing.
Second, the processes involved in transforming sensory information for perceptual decision making are different from the processes involved in transforming sensory information for the execution of actions. Thus, processes involved in perception will be instantiated in distinct neural networks from processes involved in action.
Third, sensory, decision-making, and action-planning processes are all under the influence of conceptual knowledge.
Fourth, all of these processes are shaped by learning and reward mechanisms.
