The visual control of goal-directed arm movements

The visual control of goal-directed arm movements

I will talk about how visual information about a target’s position and motion is used to guide one’s hand to the target. I will present several experiments that examined how movements are influenced by small perturbations and by sequential regularities. I will present evidence that people continuously update their movements on the basis of the latest available information about the target’s position. People appear to consider the target’s velocity across extended periods of time. They do not consider acceleration at all. They get away with using such incomplete information by compensating for recent errors. I will argue that precise interception is achieved using rather limited but constantly updated visual information.
