Description
Questions for Reading 16 1 a According to traditional theories of visual perception what does our ability to alter position of our body at a given point in space and to intercept a moving object depend onIt depends on our ability to process a number of movement variables eg distance velocity and acceleration during the early stages of executionb How is the basis for predicting when the body or an object that will arrive at a certain location formedThis early processing of visual information involves taking discrete retinal snapshots of the visual array that form the basis for predicting when the body or an object will arrive at a certain location2 What determines whether the performer is able to predict where an object or the body will be at a given time How accurately the performer is able to predict where an object or the body will be at a given time is largely determined by his or her existing knowledge of the movement situation and by the speed with which an appropriate action plan can be retrieved from the memory and then executed 3 a What according to Lee and Young provides us with a less complex estimate of time to contactA single optic variable provides us with an estimate of time to contactb Optic variable is also referred to as tauc What is the mathematical definition of tauDefined as the inverse of the rate of dilation of an image on the retina4 The faster an approaching object fills the visual field the faster the object will contact a particular point in space5 How would a performer use tau to his or her actionsPerformers can use tau to time their actions simply by determining how quickly the size of an approaching object fills the visual field6 TrueFalse If performers rely on timetocontact information to time their actions they would be able to adjust their hand movements to accommodate the changing ball size True7 What did the researchers from the Netherlands find in their experimentThe subjects were using the optical expansion rate of the oncoming ball to time their grasping movements particularly in the final 200ms before ball contactQuestions for Reading 171 What is action preparationWhat occurs between the intention to act and the initiation of movement to perform the action itself2 Define reaction time RTThe amount of time between the production of a signal telling a person to begin performing a skill3 a When considered in the context of action preparation what is RT The amount of time between the production of a signal telling a person to begin performing a skillb What is this interval time sometimes calledresponsedelay interval4 Why would a wide receiver in American football after planning his or her running route have difficulties following it in a gameBecause they may have difficulty remembering more complex tasks when there are other things that were not planned out going on around them5 TrueFalse As the number of response alternatives decreases The amount of time required to prepare the appropriate movement decreasesTrue6 Which situations do the fastest RTs occurThe fastest RTs occur in simpleRT situations which have only one stimulus and one response7 When would RT slow down
