In this context, humans make continuous sequences of sensory-motor decisions to satisfy current behavioral goals, and the role of vision is to provide the relevant information for making good decisions in order to achieve those goals. Components of a good decision include the goals, the rewards and costs associated with those goals, uncertainty about the state of the world, memory, and prediction. I will discuss these factors in the context of walking and interception tasks in both real and virtual environments. Keynote Speakers Keynote Speaker: Motor Development Infants’ actions broaden their mind Gustaf Gredebäck, University of Uppsala, Sweden Three suggestions are presented that aim to illustrate different ways in which actions broaden the mind. (Suggestion 1) Action prediction develops through co-opting. A well-developed motor system allows infants to use their own motor plans to calculate the goal of other people’s actions. In other words, we use our own knowledge about our bodies and actions to make sense of other people. (Suggestion 2) The foundations of mathematics develop through play. Highly proficient manual motor abilities allow infants to actively interact and learn about the world. Reaching and grasping provide opportunities for learning about forms, weights, sizes, and other action-related properties that enhance spatial cognition and strengthen the foundations of the number sense (the approximate number system). (Suggestion 3) Executive functions develop via interactive specialization from motor control. A successful interaction with the environment, through reaching and locomotion, require prediction, selection and inhibition. It is possible that a common process dedicated to structuring and supporting actions develop over the first years of life into separate processes controlling action and long term planning. Together these three suggested processes create a foundation for an embodied cognitive development that allows infants to learn about the world as well as illustrate the importance of active exploration and play for cognitive growth early in life.

A player can skate past a defensemen and shoot a puck over the glove of a goalie. Even if the defensemen knocks the player while going past, great players quickly adjust or even change where they shoot the puck to his or her advantage. Our ability to make such rapid motor ‘decisions’ is captured within the framework of optimal feedback control, in which a control policy specifies how one ought to move given the present state of the body (position and motion). My presentation will highlight the use of small mechanical and/or visual disturbances to probe how the motor system deals with a variety of behavioural contexts. These studies demonstrate that the motor system can generate surprisingly complex motor corrections to mechanical disturbances in as little as 60ms, including the influence of goal redundancy and avoidance of obstacles. In contrast, visual feedback begins at ~90ms, but only considers task- related factors at ~120ms. Importantly, the fact that visual feedback is slower than proprioceptive feedback makes the latter dominate feedback control during motor actions. I will also describe experiments demonstrating a role of frontoparietal cortical circuits in these fast feedback processes. Taken together, this work suggests that the voluntary motor system does not simply generate a pattern of muscle activity to attain a goal (i.e. motor program). Rather, it creates a broad range of strategies and
