A major focus of research into visually guided action (VGA) is the identification of control strategies that map optical information to actions. The traditional approach to this research has been to test the behavioral ...

Previous accounts of how humans locomote have focused on movements and perceptualjudgments along the 2D ground plane, such as when driving automobiles or walking over various types of terrain. Humans, however, can also ...

When realizing a motor goal, actors have access to a large number of redundant action possibilities from which a particular movement must be selected. Comfort has been shown to play an important role in the selection of ...

This thesis explores the impact of information processing constraints on models of human learning and decision making. This is achieved through altering existing methods within the fields of economic decision making and ...

I conducted two studies that explore the implications of the efficient coding hypothesis on neural mechanisms in primate MT and MSTd. The efficient coding hypothesis holds that neuronal populations, particularly those in ...

I present three related studies which examine the features and theoretical structures associated with extreme expertise in the complex, real-time cognitive task of Tetris. To facilitate this research, I developed a platform ...

In order to take action in the world, humans require coordination between per- ceptual information about the environment and the action capabilities endowed to us by the structure of our bodies. Within the context of ...

In Experiment 1, I demonstrated that two step lengths of visual look ahead is sufficient for humans to walk over complex terrain while exploiting the inverted-pendulum-like structure of bipedal gait as efficiently as they ...
