KNES 371 Motor Control Exam 1 Ch. 1-4
questions with verified answers
Assumptions to the theories of motor control: REFLEX - correct answer ✔✔1. Individual is a passive
recipient of externally produced sensory input.
2. Physical events occurring in the environment are the only things serving as the stimulus for action.
Assumptions to the theories of motor control: Hierarchical - correct answer ✔✔1. Representations of
movement are stored in memory in the form of plans or programs of movement.
2. The control of movements occurs in a "top-down" manner.
Assumptions to the theories of motor control: Dynamical Systems - correct answer ✔✔1. Changes in
movement behavior can occur in a nonlinear and abrupt fashion.
2. New movement patterns are facilitated by changes in one or more control parameters.
Assumptions to the theories of motor control: Ecological - correct answer ✔✔1. Motor behavior
emerges from a perceptual interface between individual and environment.
A preferred pattern of behavior or coordination. - correct answer ✔✔Attractor State
Allows the performance of movements in the absence of feedback - correct answer ✔✔Open Loop
motor control
The study of postures and movements and the mechanisms underlying them - correct answer ✔✔Motor
Control
A system of that is used to perform slow and precise movements - correct answer ✔✔Closed Loop
motor control
The ability to perform the same movement using different muscle groups - correct answer ✔✔Flexibility
, A variable, that when altered, can lead to changes in the pattern of coordination - correct answer
✔✔Control of Parameter
A variable used to quantify the effect of the change in behavior - correct answer ✔✔Order parameter
The ability to change a movement pattern - correct answer ✔✔Modifiability
Abstract memory representation of a movement - correct answer ✔✔Generalized motor program
According to the Dynamical Systems approach, what leads to the change in sitting pattern observed
when women reach late stages of pregnancy - correct answer ✔✔Changes in the characteristics of the
individual
The Hierarchical Theories are said to be better at explaining: - correct answer ✔✔Rule-Based
movements
The characteristic of human action that explains how certain aspects of a movement are relatively stable
from one performance to the next is: - correct answer ✔✔Consistency
A situation in football where the coach instructs the quarterback to throw to a particular receiver even
though other response choices could be made is an example of a: - correct answer ✔✔Discrimination
reaction time situation
The component of fractionated reaction time that measures the cognitive processes associated with
movement planning is called: - correct answer ✔✔Premotor time
Reaction time is increased when - correct answer ✔✔THe complexity of the response is increased
Motor time is defined as the - correct answer ✔✔Time interval from the first change in electrical activity
in the muscle to the actual start of the movement.
