Question 1

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

Accepted Answer

The answer of An important role of proprioceptive feedback in...

Question 2

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.

Accepted Answer

This statement is true. It is known as the nasal-temporal division of retinal ganglion cells and is responsible for the lateralization of visual perception.

Question 3

A sensory neuropathy involving a limb provides a non-surgical technique for the investigation of deafferented humans.

Accepted Answer

A sensory neuropathy involving a limb, such as diabetic neuropathy, can be used as a non-surgical technique to investigate how the brain adapts to the loss of sensory input from the affected limb. This can provide insights into sensory processing and plasticity in humans.

Question 4

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

Accepted Answer

The answer of The clear surface that is the most...

Question 5

Peripheral vision provides essential information during a discus throw.

Accepted Answer

The answer of Peripheral vision provides essential information during a...

Question 6

Monocular vision leads to better interception of a moving object than binocular vision.

Accepted Answer

Binocular vision provides depth perception and better spatial awareness, which are crucial for accurately intercepting moving objects. Monocular vision lacks the depth cues that come from binocular disparity, making it harder to judge distances and speeds accurately.

Question 7

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.

Accepted Answer

The answer of When a researcher shows a video in...

Question 8

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.

Accepted Answer

The ventral visual stream is responsible for processing and identifying visual information relating to object recognition, color, texture, and shape. This information is consciously perceived and thus we are aware of it. On the other hand, the dorsal visual stream is responsible for processing spatial location, motion, and depth perception, which is not always consciously perceived, hence generally, we are not aware of it.

Question 9

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

Accepted Answer

Typing accuracy can be impaired when tactile sensory feedback from the fingertips is removed, as it is an important factor in detecting errors and making corrections while typing.

Question 10

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.

Accepted Answer

Peripheral vision is important in detecting potential obstacles or hazards on the sides of the pathway, such as other pedestrians or uneven terrain.

Question 11

________ perception is enhanced by the availability of binocular vision.

Accepted Answer

The answer of ________ perception is enhanced by the availability...

Question 12

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

Accepted Answer

The answer of The are proprioceptors located within the fibers...

Question 13

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

Accepted Answer

Visual feedback is only effective in correcting a movement if there is enough time to make the correction based on the information provided by the feedback. If the movement is too quick or the feedback is delayed, the correction may not be possible.

Question 14

The optic nerves from the two eyes meet near the base of the brain and form the optic.

Accepted Answer

The answer of The optic nerves from the two eyes...

Question 15

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

Accepted Answer

Perception-action coupling is the coordination between visual perception and limb movement. It refers to the ability of an organism to use visual information to guide actions, such as reaching for an object or avoiding an obstacle. This coupling allows for efficient and effective movement in the environment.

Question 16

The optical variable ________ has been shown to influence the control of time-to-contact in locomotor skills.

Accepted Answer

The answer of The optical variable ________ has been shown...

Question 17

Peripheral vision helps people maintain their postural balance while walking by utilizing patterns of _________ in the environment.

Accepted Answer

The answer of Peripheral vision helps people maintain their postural...

Question 18

In the experiment by Sivak and MacKenzie,when participants' peripheral vision was blocked,the grasping phase of a prehension action was disrupted.

Accepted Answer

The answer of In the experiment by Sivak and MacKenzie,when...

Question 19

The retina is actually an extension of the brain.

Accepted Answer

The retina is considered an extension of the brain because it is made up of neural tissue and functions as a specialized part of the central nervous system. Its nerve cells process visual information before sending it to the brain for further interpretation.

Question 20

The rods are the photoreceptors in the retina that respond to low levels of light,whereas cones respond to bright light.

Accepted Answer

This statement is correct. The rods are responsible for vision in low light conditions, while cones are responsible for color vision and vision in bright light.
