Knh 184 Study guides, Class notes & Summaries

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

KNH 184 Exam 2 (from actual exam)

What are the three subdisciplines of motor behavior? - 1. Motor Control 2. Motor Learning 3. Motor Development Motor Control - Study of how movements are controlled Motor Learning - Study of how motor skills are acquired Motor Development - Study of how motor skills are developed The term motor skill can be conceptualized i

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

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

According to Hick's Law, what happens every time the number of stimulus-response alternatives doubles? - 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. - generalized motor program / novelty / storage The inverted-U hypothesis suggests t...

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
