Exam 6: Sensory Components of Motor Control

________ perception is enhanced by the availability of binocular vision.

When you are walking on a pathway,central vision provides the information you need to stay on the pathway but peripheral vision provides no important information as you walk.

A person can use visual feedback to correct a movement only when there is a sufficient amount of time to make the correction.

The greatest concentration of __________ sensory receptors is in the fingertips.

The are proprioceptors located within the fibers of most skeletal muscles;they detect changes in muscle length.

The procedure in which a person's body parts are masked on film or video frames so that they cannot be seen by an observer is known as the:

We are generally consciously aware of the information provided by the ventral visual stream but not aware of the information provided by the dorsal visual stream.

In the experiment by Spencer and others (2005)in which two sensory neuropathy patients were compared to control participants,the repetitive circles drawn by the patients were:

Typing accuracy is generally not impaired when tactile sensory feedback from the fingertips is removed.

Which of the following techniques that researchers use to study the role of proprioception in motor control does not remove proprioceptive feedback but only distorts it?

Perception-action coupling is confined to the hands and feet.

When used to refer to vision,the term "perception-action coupling" refers to the coordination between visual perception and limb movement.

The retina is actually an extension of the brain.

Which of the following movement characteristics is influenced by tactile sensory information?

The optic nerve fibers associated with the nasal part of the visual field cross over to the opposite hemisphere whereas the fibers associated with the temporal part of the visual field do not cross to the opposite hemisphere.

The clear surface that is the most anterior part of the eye is the.

When a researcher shows a video in which certain parts of a person's movements are masked,the research uses the occlusion procedure for investigating the role of vision in performing motor skills.

Although people can use monocular vision to reach and pick up objects,movement accuracy and efficiency decrease as the:

The procedure in which a film simulation of a skilled performance is stopped and the person is asked to indicate the outcome of the performance is known as the:

An important role of proprioceptive feedback in the control of movement is to provide information about the ________ of the movement.
