Question
rtance, especially when we have to quickly react to a espe e way in which we can optimize our environment so that Timing of movements is of utmost perceived stimuli. A) What is on more quickly to stimuli? Describe this process in full. B) Some standard simple reaction time when movements are sequenced. Name and d strategy that people can use to quickly perform a second movement after a f of the six motor skills that requires speed and accuracy to perform, and describea that helps us understand how people can be both fast and accurate movements are shorter than a we react describe a movement rst one.C Choose one theory or modelExplanation / Answer
A. The one way to optimise our environment so that we can react to stimuli is cognitive ability. Reaction time is nothing but the amount of time taken between when we perceive something to when we respond to it. It depends on various factors like perception, processing and response. It necessarily includes a motor component unlike processing speed .
Reaction time can vary sometime depending on factors like :
* the complexity of stimulus
* stimulated sensory modality
* stateof organism
* familiarity, preparations and expectations .
B. A person can perform movements at same speed or at different speed. During the second movement, the inertial load increases four fold unexpectedly.Then the speed of movement will falls apparently. This movement drop will be reflected in the activity levels of peripheral receptors.
The dual strategy hypothesis successfully describes the regulation in the first EMG burst during single joint movements. The idea behind this is straight forward .
C. The speed and accuracy phenomenon is one of the most often observed occurrences in movement behaviour. It is a characteristic of motor skill performance in which the speed at which a skill is performed is influenced by movement accuracy demand.
The goal and nature of task determines how speed and accuracy will effect the performance. Many tasks has both speed and accuracy requirements. The beat way to approach these tasks is to try to move as fast as you can without sacrificing accuracy.
The model of neural mechanisms can be considered in speed and accuracy.They balance speed of responding with accuracy of making decisions.
