Question 1

Hearing is to _____ as smell is to _____.

Accepted Answer

Hearing involves detecting sound waves, while smelling involves detecting airborne molecules that carry odor. Therefore, the correct pair would be sound waves and airborne odor molecules. Choices A, C, and D are incorrect because they do not correctly match hearing and smell.

Question 2

The kinesthetic sense involves:

Accepted Answer

The kinesthetic sense involves the proprioceptors, which are sensory receptors located in muscles, tendons, and joints. These receptors provide information about the position, movement, and tension of our body parts, which allows us to perceive body position and movement.

B, C, and D are not related to the kinesthetic sense. Nociceptors detect pain, substance P is a neuropeptide involved in pain transmission, and C-fibers are unmyelinated nerve fibers that transmit pain and temperature information.

Question 3

The term kinesthetics means feelings of:

Accepted Answer

The term kinesthetics refers to the sense of motion and physical movement. It is related to the awareness and perception of bodily movement and position. Thus, the best choice is D - motion.

Question 4

Your exercise teacher instructs you to do five deep knee bends. Your ability to do knee bends without toppling over involves your:

Accepted Answer

The answer of Your exercise teacher instructs you to do...

Question 5

When we draw on our knowledge, experiences, expectations, and other cognitive processes to arrive at meaningful perceptions, we are using:

Accepted Answer

Top-down processing refers to the use of higher-level cognitive processes, such as prior knowledge and expectations, to interpret incoming sensory information and arrive at meaningful perceptions. Bottom-up processing, on the other hand, refers to the processing of incoming sensory information from the lower-level features to higher-level perceptual representations. Proprioception refers to the sense of body position and movement, and accommodation refers to the adjustment of the lens of the eye to focus on near or distant objects. Therefore, the best choice in this scenario is B (top-down processing).

Question 6

Flying across the country, you encounter turbulent, rough air. The plane begins to bounce and sway. You begin to feel nauseated and airsick. Your motion sickness is caused by:

Accepted Answer

Motion sickness is caused by conflicting sensory information from the eyes and vestibular system. The eyes tell the brain that the body is not moving, while the vestibular system senses motion. This conflicting information results in nausea and other symptoms of motion sickness.

Question 7

You are able to bring a cup to your lips and sip your coffee without looking at your face or hand because of your _____ sense.

Accepted Answer

The kinesthetic sense is the sense of the position and movement of body parts, including the ability to sense the location of one's own body parts without visual feedback. This allows us to bring a cup to our lips and sip without needing to look at our hand or face. The vestibular sense is related to balance and spatial orientation, while the sense of equilibrium is part of the vestibular system. The visual sense is not directly involved in the act of bringing a cup to one's lips and sipping.

Question 8

The flow of sensory data from the sensory receptors to the brain is called _____ processing.

Accepted Answer

Bottom-up processing refers to the flow of information from sensory receptors to the brain, with the brain constructing perceptions from this raw sensory data. Choice A and D are not accurate terms for this type of processing, and top-down processing refers to the brain using prior knowledge and higher-level cognitive processes to interpret sensory input, which is not the same as the flow of sensory data from receptors to the brain.

Question 9

According to your text phantom limb pain seems to be the result of:

Accepted Answer

Phantom limb pain is thought to be the result of sensitization of the pain transmission pathways in the nervous system. This can occur due to the rewiring of the neural pathways after amputation, leading to abnormal signaling that can be interpreted by the brain as pain. Pain gates being stuck in the open position (A) is a theory related to chronic pain, and may not be specifically applicable to phantom limb pain. Lack of kinesthetic awareness (B) may contribute to muscle weakness or imbalance, but is not directly linked to phantom limb pain. Damage to the somatosensory or motor cortex in the brain (D) can result in other types of sensory or motor impairments, but is not necessarily linked to phantom limb pain.

Question 10

Bottom-up processing is to top-down processing as _____ is to _____.

Accepted Answer

Bottom-up processing refers to data-driven processing, where sensory information is analyzed and combined to form a perception. Top-down processing, on the other hand, refers to conceptually driven processing, where prior knowledge and experience are used to interpret incoming sensory information. Kinesthetic processing and proprioceptive processing both refer to processing related to bodily movement and awareness of body position, but this is not relevant to the comparison between bottom-up and top-down processing. Similarly, perception and sensation are related concepts but do not capture the comparison between data-driven and conceptually-driven processing. Finally, while vision and audition are two sensory modalities that can be compared, this does not capture the comparison between bottom-up and top-down processing.

Question 11

Imagine trying to assemble a jigsaw puzzle one piece at a time without knowing what the final picture will be. To accomplish this task, you would work with the individual pieces to build the image using _____ processing.

Accepted Answer

Bottom-up processing involves constructing a whole perception from separate pieces of sensory information. In this scenario, the individual pieces of the jigsaw puzzle would be processed bottom-up to build the final image.

Question 12

You are able to maintain your equilibrium and balance because of the:

Accepted Answer

The vestibular sense is responsible for maintaining balance and equilibrium in the body. It involves the sensory organs in the inner ear that sense movements of the head and provide information about the body's position and orientation in space. The other options, kinesthetic sense, proprioceptors in the inner ear, and nociceptors in the inner ear, are not directly related to maintaining balance and equilibrium in the body.

Question 13

Jenny is looking at a picture in a newspaper and recognizes the person in the picture as her ex-boyfriend. What perceptual processing is she using?

Accepted Answer

Jenny is using top-down processing because she is using her prior knowledge and expectations (knowing what her ex-boyfriend looks like) to recognize him in the picture.

Question 14

After an injury has healed, it is still possible to experience pain signals from the injured site due to the process of:

Accepted Answer

Sensitization refers to an increased sensitivity of nerve fibers in response to injury or other stimuli. This can lead to the perception of pain even after the initial injury has healed. Adaptation refers to a decrease in sensitivity of nerve fibers over time, which would not contribute to continued pain signals. Hallucination refers to a perception of something that is not actually there, which is not relevant to physical pain sensations. Generalization refers to the spread of a response to stimuli that are similar to the original stimulus, which is also not relevant to the continued perception of pain signals after injury.

Question 15

This image depicts some of the key structures of the ear. Which structure plays a key role in the vestibular sense?

Accepted Answer

The semicircular canals play a key role in the vestibular sense, which is responsible for detecting changes in head position and movement, and maintaining balance and orientation. The other structures listed (cochlea, eardrum, pinna) are involved in hearing, but not the vestibular sense.

Question 16

Sensory adaptation is the opposite of:

Accepted Answer

Sensory adaptation is the decrease in sensitivity to a stimulus over time. Sensitization, on the other hand, is an increase in sensitivity to a stimulus. Therefore, A is the correct answer as it is the opposite of sensory adaptation. Generalization, exaptation, and survival are not related to sensory adaptation in this context.

Question 17

When pain pathways become more responsive to repeated stimulation over time, it is called:

Accepted Answer

When pain pathways become more responsive to repeated stimulation over time, it is called sensitization. This means that the body becomes more sensitive to pain, and even mild stimuli can trigger a painful response. This can lead to chronic pain conditions and can make it difficult to manage pain effectively.

Question 18

Phantom limb pain occurs when a person experiences pain:

Accepted Answer

Phantom limb pain is the sensation of pain or discomfort felt in a body part that has been amputated or is no longer there. It is a well-known and relatively common phenomenon experienced by amputees.

Question 19

In physical education class, your teacher instructs you to close your eyes and touch your toes. Your ability to touch your toes even though you can't see them is due to your _____ sense.

Accepted Answer

The kinesthetic sense, also known as proprioception, is the sense that helps us understand where our body parts are located in relation to each other and in space. It allows us to perform movements without having to look at our body, such as touching our toes with our eyes closed. The other senses listed, vestibular, nociceptor, and skin, do not directly contribute to our ability to touch our toes with our eyes closed.

Question 20

Changes in your body position are sensed by specialized receptors located in your muscles and joints which are called:

Accepted Answer

Changes in body position are sensed by proprioceptors located in the muscles and joints. Kinesthetic receptors and vestibular sacs exist, but they are involved in other aspects of sensing body position and movement, such as balance and orientation in space. Semicircular canals are involved in detecting rotational movement of the head.
