Question 1

When Clyde is pricked by a needle,the sharp pain signal is carried to the brain by ____fibers.The next day,Clyde feels a dull ache around the spot where he was pricked; this information is carried by ____ fibers

Accepted Answer

A-delta fibers are responsible for carrying the fast, sharp pain signals, while C fibers carry slower, dull, and aching pain signals.

Question 2

You are walking across campus and you notice an odor that is coming from livestock in the area.Due to neural pathways,the smell is most likely to evoke a(n)____.

Accepted Answer

The odor of livestock is likely to evoke an emotional response due to the amygdala, a part of the brain responsible for processing emotions such as fear, disgust, and anger. The odor may trigger memories or associations with previous experiences and cause an emotional reaction.

Question 3

In his Pilates class,Ben's instructor explains how to change focus away from the external world and instead focus on the internal senses.In other words,his instructor is asking the class to pay attention to their ____ senses.

Accepted Answer

The instructor is asking the class to focus on their internal senses, which refers to proprioception - the ability to sense the position, movement, and orientation of the body. Exteroceptive senses relate to the external world (such as touch or temperature), olfactory senses relate to smell, and gustational senses relate to taste.

Question 4

While randomly searching through Wikipedia,you read an article on the cutaneous senses.You now understand that the cutaneous senses consist of all of the following except____.

Accepted Answer

As per the given options, the cutaneous senses consist of touch, temperature, and pain, but flavor is not a part of cutaneous senses. Flavor is a perception that is a combination of taste and the sense of smell.

Question 5

While watching a Food Network marathon,you learn from Rachel Ray that papillae are groups of ____ that play an important role in taste perception.

Accepted Answer

Papillae are small bumps on the tongue that house taste buds, which contain receptors that detect different tastes such as sweet, sour, salty, bitter, and umami. Therefore, papillae are groups of receptors that play an important role in taste perception. Accessory structures, feature detectors, and C-fibers are not directly related to taste perception.

Question 6

During an intense game of volleyball,Shay slipped and banged her knee on the floor."Ouch!" she cried,as she wishes her brain would produce more ____.

Accepted Answer

Endorphins are hormones naturally produced by the body that act as painkillers and provide a sense of well-being. They are released during exercise and other physically demanding activities and can help reduce the pain Shay is feeling.

Question 7

As soon as Rashidat catches a whiff of the cologne of the woman sitting in front of him in class,he is attracted to her.Though she is a complete stranger,her smell is familiar.He is unable to place the smell,but it brings back good memories.Why?

Accepted Answer

The olfactory bulb, responsible for detecting smells, has strong connections to the amygdala, which is involved in emotions and memory. This explains why the scent triggered good memories in Rashidat despite him not being able to place the smell. The other options are less likely. Option A refers to pheromones, which are chemical signals that trigger a response in the opposite sex, but it is unlikely that Rashidat's attraction to the woman was solely due to pheromones. Option C refers to a different system for detecting pheromones, which is not believed to play a significant role in humans. Option D is speculative and unlikely without more information about the specific odor type.

Question 8

While at a party,you notice an attractive person staring at you.According to principles of perceptual organization,you are likely to focus on this attractive person as the ____ and relegate other people at the party to be the ____.

Accepted Answer

According to principles of perceptual organization, when visual attention is drawn to one object, that object becomes the figure and the background becomes the ground. Therefore, in this scenario, the attractive person staring at you would be perceived as the figure, while the other people at the party would be perceived as the background or ground. Choice C captures this concept.

Question 9

Doctor Payne,a dentist,is trying to decide if he should explain to his patients the kind of pain they will endure before performing certain procedures.According to your text,if Doctor Payne does this,the patients will be more likely to ____.

Accepted Answer

According to the text, if Doctor Payne explains the kind of pain his patients will endure before performing certain procedures, they will be more likely to cognitively prepare for the pain and therefore object less to it. It does not mention that they will report a higher degree of pain, find difficulty focusing on pleasant distractions, or release endorphins to block the painful experience.

Question 10

After falling from his perch,the Scarecrow has difficulty sensing where his body parts are in relation to each other.This makes it difficult for him to move easily,but eventually he is able to adapt,thanks to special cells in his joints and muscles called ____.

Accepted Answer

Proprioceptors are specialized cells present in joints and muscles that provide information about the position and movement of body parts. They play a crucial role in maintaining balance, coordination, and body awareness. In the case of the Scarecrow, the proprioceptors help him adapt to his difficulty in sensing the position of his body parts, allowing him to eventually move easily. Options A, B, and C are not directly related to the Scarecrow's condition.

Question 11

During a war,soldiers wear camouflage clothing to avoid being perceived by enemies.The perceptual cue that is being manipulated in this case is ____.

Accepted Answer

Figure-ground discrimination involves separating an object from its background. Camouflage clothing is designed to blend in with the surroundings, thus making it difficult for the enemy to discern the soldier from the background, and to identify the figure hiding in the ground. Therefore, the perceptual cue being manipulated in this case is figure-ground discrimination.

Question 12

Which statement about the taste buds is correct?

Accepted Answer

Each taste bud contains specialized cells that respond most strongly to one or two types of taste (sweet, sour, salty, bitter, umami) but can also detect other taste sensations to some degree. This is why food can have a complex mix of flavors.

Question 13

Which effect most likely causes astronauts to become nauseated in space?

Accepted Answer

The vestibular system, which helps us maintain balance and orientation in space, becomes confused in the absence of gravity. This can lead to motion sickness, including nausea and vomiting.

Question 14

After smashing his foot,Gwo-Ling feels no pain because messages from his brain block incoming pain messages.This effect is called ____.

Accepted Answer

Analgesia is the inability to feel pain while still being conscious. It can result from various causes, including the brain's ability to block incoming pain messages. This phenomenon is a type of pain inhibition, where the brain sends signals that prevent the transmission of pain signals to the conscious mind. Therefore, the best answer is A) analgesia.

Question 15

"While watching a crowd of people,one does not focus on individual colors,movements,and shapes.Instead,one perceives the event as a whole." This statement has most likely been made by a ____.

Accepted Answer

The statement relates to the concept of Gestalt psychology, which emphasizes the importance of perceptual organization and the tendency of the brain to group stimuli into a whole. Cognitive psychology also deals with perception, but it focuses more on the underlying mental processes. Functionalism and structuralism are early schools of psychology that are no longer as relevant to modern psychology as Gestalt and cognitive psychology.

Question 16

Shawn's leg has fallen asleep and now he has trouble walking because he cannot determine the position of his leg in space.Shawn has lost his ____.

Accepted Answer

Kinesthetic perception, also known as proprioception, is the ability to perceive the position and movement of one's body parts. Losing kinesthetic perception would make it difficult for Shawn to determine the position of his leg in space and thus affect his ability to walk. Losing the sense of equilibrium would affect his balance, which is not the case here. Olfactory perception and gustation are related to smell and taste respectively and not relevant to Shawn's leg sensation.

Question 17

Little Erika picks up a spider,carries it to her mother,and asks,"Mommy,what is this little,soft,cuddly thing?" Little Erika's inability to recognize what the spider is or the potential danger of picking it up demonstrates that perception is ____.

Accepted Answer

Perception is knowledge-based because it relies on prior knowledge and experiences to interpret sensory information. Little Erika's lack of knowledge about spiders leads to her misperception.

Question 18

Dyanna is meeting her friends at the football game.When she arrives late at the stadium,she automatically looks for a cluster of people wearing colorful jester hats.Dyanna is relying on ____to find her friends more easily.

Accepted Answer

Dyanna is using the principle of grouping, which is the perceptual tendency to organize stimuli into coherent groups based on proximity, similarity, continuity, and closure. In this case, she is looking for a cluster of people wearing the same type of hat, which is an example of grouping based on similarity.

Question 19

After riding several roller coasters,you find that you feel nauseous.You feel the nausea because your ____ has been overstimulated.

Accepted Answer

The sense of equilibrium, also known as the vestibular system, helps us maintain balance and sense movement. This system is responsible for sending signals to our brain about changes in motion and position. When we ride roller coasters or experience other sudden changes in motion, our sense of equilibrium can become overstimulated, leading to feelings of nausea.

Question 20

If sensation equals raw data,then perception equals ____.

Accepted Answer

Perception involves the analysis and interpretation of the raw data received through sensation. Therefore, perception is the process by which sensory information is organized and interpreted to form a meaningful experience. Internal noise (A) refers to the interference within an organism that may be caused by physiological or psychological factors, and is not related to perception. Statistical significance (C) and psychophysics (D) are related to the quantitative measurement and analysis of sensory information, but are not equivalent to perception.
