Motor learning - How do we acquire movement skills? Motor Skills - Movements are the component parts of... To produce adaptable and complex movements - According to Daniel Wolpert, what is the reason we have a brain? Cerebral Cortex - Which part of the brain initiates voluntary movement? Brainstem - In which part of the brain do the sensory and motor neurons cross from one side of the body to the other? Frontal - In which part of the brain does motor cortex exist? Reaction Time - The tim...

Physical guidance is a strong positive motor performance variable, but a weak positive motor learning variable. - Answer-True Augmented feedback should be provided to a learner instantaneously after a practice trial so she/he can quickly decide what to do differently on the next practice trial. - Answer-False One of the reasons a retention interval must be included in a transfer/retention design is to allow any temporary effects of practice to dissipate (go away). - Answer-True A performan...

The ______ controls communication between the cerebellum and the cerebrum/cerebral cortex - Answer-pons What is the ability to manipulate relatively large objects with your hands and arms - Answer-Manual Dexterity What happens during rapid elbow flexion.. the triceps muscle (two things) - Answer-is inhibited and acts as the antagonist What types of neurons convey information from the CNS to the periphery? - Answer-motor, descending, efferent If you found a correlation coefficient of .75 ...

Two fundamental Questions - Answer-How do we acquire movement skills? How do we control movement skills? Three sub disciplines of motor behavior - Answer-1) motor learning 2) motor control 3) motor development Motor Behavior - Answer-people do things by exerting muscular contractions Motor Control - Answer-examines the control mechanisms for movement Motor learning - Answer-set of internal and mental processes associated with practice or experience leading to relatively permanent gains in...

What are the three subdisciplines of motor behavior? - Answer-1. Motor Control 2. Motor Learning 3. Motor Development Motor Control - Answer-Study of how movements are controlled Motor Learning - Answer-Study of how motor skills are acquired Motor Development - Answer-Study of how motor skills are developed The term motor skill can be conceptualized in two ways. What are those? - Answer-1. Skill can be seen as a task EX: Swimming, Skating 2. Skill can be viewed as a level of performance...

According to Hick's Law, what happens every time the number of stimulus-response alternatives doubles? - Answer-1. the performer's response selection stage of information processing takes longer 2. the performer's RT increases by a constant amount The _________________________ theory was developed to address the ___________________ and ____________________ problems with the original concept of motor programs. - Answer-generalized motor program / novelty / storage The inverted-U hypothes...

Reaction Time - Answer-Time it takes to respond and initiate movement (average is 120-280 ms) Movement Time - Answer-Time from initiated movement until the end of the movement Response time - Answer-Time it takes to respond until the end of movement (Reaction time + Movement time) Stimulus Identification Stage - Answer-The stimulus is recognized and identified-- sensory stage (vision, audition, touch, kinethesis, smell) Parallel processing usually occurs during this stage Response Selectio...

Motor Behavior - Study of movement and processes that underlie motor performance Motor Control - Examines control mechanism of movement Motor Learning - Learning movements through practice History of Motor Skills - WWII- need for trained military with skillful movements Fritts' Law (1954) - Speed accuracy trade-off Dr. Franklin Henry - University of California Berkley, Father of motor behavior research Movement - Change in position of a body segment. Are a component part of motor skills ...

Reaction Time - Time it takes to respond and initiate movement (average is 120-280 ms) Movement Time - Time from initiated movement until the end of the movement Response time - Time it takes to respond until the end of movement (Reaction time + Movement time) Stimulus Identification Stage - The stimulus is recognized and identified-- sensory stage (vision, audition, touch, kinethesis, smell) Parallel processing usually occurs during this stage
