I am intersted in how the brain controls movement. My research has focused on several topics:
Observing cognitive processes through arm movements
Reaction times have commonly been used as a way of studying various cognitive processes. We can modify the input and see the effect on the output (e.g. it takes longer to decide if uncommon words are words compared to common words), and hopefully inform our understanding about cognitive processes. But by using arm movements rather than reaction times, we can observe parts of the process leading up to the final decision, which can provide us much more information about how these processes work.
My research has involved using my backgroun in motor control to inform these studies. We have used these techniques in stuides of maksed priming (Finkbeiner & Friedman, 2011) and the role of spatial frequencies in face detection (Awasthi, Friedman & Williams, 2011). I am also developing models to predict how we use partially accumulated evidence to produce these movements.
Grasping
The human hand has amazing ablities to grasp and dextrously manipulate objects, which until today have not been reproduced using robotic hands. My research has looked at some of the ways we exploit the redundancy in the human hand (in that we have more degrees of freedom than necessary) to successfully use our hands. I have looked at the kinematics (movements) of grasping: how the graps we select are affected by the task (Friedman & Flash, 2007), and the trajectories we choose when grasping (Friedman & Flash, 2009). I have also looked at how we coordinate forces during grasping (Friedman, Latash & Zatsiorsky, 2009, Latash et al. 2010) and how the variance is coordinated when using multiple fingers during force production (Kapur et al., 2010, Friedman et al., 2009).
