Exam 5: Motor Control Theories

When we consider the assessment of movement characteristics associated with the performance of a skill, it is necessary to use the term coordination to refer to the relationship among the joints and segments at any specific point in time during the skill performance.

Dynamical systems theories of motor control view the control of complex coordinated action from the perspective of ________ dynamics.

The dynamical systems theory indicates that skilled action is controlled by the nervous system constraining functionally specific collectives of muscles and joints, which are known as:

According to the dynamical systems theory, which of the following define, or identify, a specific movement pattern?

In Shapiro and others' experiment on relative timing patterns in walking and running, a motor program-based theory of motor control would conclude that:

Coordination should be considered in terms of body and limb movement patterns in relation to:

Coordinative structures can develop through practice.

The degrees of freedom problem, which the nervous system must solve so that a person can achieve the action goal of a complex motor skill, involves determining:

That people spontaneously change from a walking to a running coordination pattern at a certain speed demonstrates that patterns of movement coordination can self-organize.

Which of the following types of motor control theories emphasizes the role of a memory representation in the control of coordinated action?

According to a dynamical systems theory, the muscles and joints that act together to enable a person to reach and grasp a cup are known as a ________.

According to the dynamical systems theory, walking and running represent two distinct ________ states of coordination.

Dynamical systems theory de-emphasizes the role of executive commands to the musculature and emphasizes the role of the ______ properties of the body and limbs.

You perform a four-component movement in 10 sec, and then in 20 sec. If relative time is invariant, and component 1 takes 2.5 sec for the 10-sec movement time, component 1 would require ______ sec for the 20-sec movement time.

An important difference between the open- and closed-loop control systems is that the:

The action of throwing a dart at a dartboard is an example of a motor skill that is controlled by:

According to a dynamical systems view of motor control, skilled action occurs on the basis of action units:

The affordance concept suggests that we:

According to Schmidt's motor program-based theory of motor control, which of the following would be controlled by the same generalized motor program (GMP)?

A traffic signal that is preset to cycle through the time sequences for the onset of the green-yellow-red light sequence is a mechanical example of an open-loop control system.
