Sensorimotor strategy selection under time constraints in the presence of two motor targets with different values

Abstract Goal-directed movements often require choosing an option from multiple potential goals under time constraints. However, there are limited studies on how humans change their time spent on decision-making and movement patterns according to time constraints. Here, we examined how sensorimotor...
