Question 1

Mercedes just stubbed her toe on the edge of her bedpost.In response,her brain will most likely signal the release of

Accepted Answer

Endorphins are released in response to pain, and act as natural painkillers.

Question 2

Compared to fibers that carry signals about temperature and touch,pain fibers associated with dull or throbbing pain are

Accepted Answer

Pain fibers associated with dull or throbbing pain are thinner and slower than fibers that carry signals about temperature and touch. This is because pain fibers are unmyelinated, which slows down the transmission of signals.

Question 3

The process by which the brain interprets stimuli and turns them into meaningful representations of the external world is

Accepted Answer

Sensation is the process of detecting sensory information, while perception involves organizing and interpreting that information to create a meaningful experience. Attention is the process of focusing on specific stimuli, and memory involves the retention and retrieval of information over time. Psychokinesis refers to the alleged ability to move objects with the power of one's mind, which is not a recognized or accepted concept in mainstream psychology. Therefore, the best choice is B) perception, as it accurately describes the process of interpreting sensory information to create a meaningful experience.

Question 4

Limiting attention to certain stimuli and filtering out other stimuli is called

Accepted Answer

Selective attention refers to the ability to focus on certain stimuli while filtering out others.

Question 5

Regarding acupuncture,which of the following statements is FALSE?

Accepted Answer

While there is some scientific evidence supporting the effectiveness of acupuncture, there are also studies that have found it to be no more effective than a placebo. Therefore, it is not entirely ruled out that acupuncture could be a placebo effect.

Question 6

Receptors for kinesthesis are located in

Accepted Answer

Kinesthesis refers to our sense of movement and body position. Receptors for kinesthesis are located in the joints, ligaments, tendons, and muscles, which allow us to sense the position and movement of our body parts.

Question 7

When Clara interacts with her sister,Shirley,Clara's interpretations of Shirley's behavior and comments are influenced by preconceptions and expectations from their previous experiences.Which term describes this dynamic?

Accepted Answer

Clara's preconceptions and expectations from previous experiences are forming a psychological set that influences her perception of Shirley's behavior and comments. This is known as a perceptual set, which refers to a tendency to perceive and interpret sensory information in a particular way based on context and prior knowledge.

Question 8

Regarding perceptual processing,which of the following statements is FALSE?

Accepted Answer

Facial recognition is an example of top-down processing, as it involves using prior knowledge and expectations to interpret sensory input. Bottom-up processing involves starting with sensory input and building up to a perception or understanding.

Question 9

Austin experiences motion sickness on his first cruise vacation.From which two senses has Austin received conflicting information?

Accepted Answer

Austin is experiencing motion sickness, which occurs when there is conflicting information between the vestibular (balance) system and the visual system (eyes). This suggests that he is experiencing conflicting information between his vestibular and visual senses.

Question 10

The vestibular sensory system includes

Accepted Answer

The vestibular sensory system includes both the semicircular canals and the vestibular sacs. The semicircular canals detect rotational movement, while the vestibular sacs detect linear acceleration and head position relative to gravity. The olfactory receptors are part of the sense of smell and are not part of the vestibular system.

Question 11

Regarding attention,which of the following statements is FALSE?

Accepted Answer

Repeated exposure to a changing stimulus actually leads to sensitization, not habituation. Habituation refers to a decrease in response to a stimulus after repeated exposure, while sensitization refers to an increase in response to a stimulus after repeated exposure.

Question 12

Receptors for which of the following are located deepest in the skin?

Accepted Answer

Pressure receptors are located deepest in the skin. These receptors, known as mechanoreceptors, are specifically designed to detect mechanical pressure or distortions within the skin. They are situated deeper compared to other sensory receptors like those for hot, cold, pain, and light touch, which are more superficially located to quickly respond to external stimuli.

Question 13

Pain receptors are located in all but which of the following?

Accepted Answer

Pain receptors, also known as nociceptors, are not located in tooth enamel. They are located in muscles, ligaments, joints, skin, and other tissues throughout the body.

Question 14

Regarding perception,which of the following statements is TRUE?

Accepted Answer

Perception is the brain's interpretation and organization of sensory information from the environment. It involves applying past experiences and knowledge to make sense of the incoming data. Therefore, option A is the correct statement. Option B is incorrect because perception is an active process, not reactive. Option C is also incorrect because perception is subjective and can vary from person to person. Option D is incorrect because all sensory modalities have received research attention, not just auditory perception. Option E is incorrect because attention is an integral part of perception; it is not a separate step.

Question 15

When you are presented with the following visual information,"A," your brain sees a series of lines and angles in a particular format and interprets this visual information as the letter "A." This is an example of which concept from perception?

Accepted Answer

The answer of When you are presented with the following...

Question 16

In a research experiment,participants are shown a series of drawings before seeing an ambiguous picture that could be perceived as a rat or a man.Group 1 sees drawings of animals,while Group 2 sees drawings of humans.Perceptual set suggests which of the following results when participants are shown the ambiguous picture?

Accepted Answer

Perceptual set suggests that the participants in Group 1 will perceive the ambiguous picture as a rat because they have been primed by the drawings of animals they were shown before. Conversely, Group 2 will perceive the ambiguous picture as a man because they were shown drawings of humans. Therefore, Group 1 will report seeing a rat, while Group 2 will report seeing a man.

Question 17

When you perceive something,what is the first step you take?

Accepted Answer

The answer of When you perceive something,what is the first...

Question 18

Regarding the skin senses,which of the following statements is FALSE?

Accepted Answer

Not all skin receptors respond to more than one type of stimulation. Some receptors are specialized for detecting specific types of stimuli, such as temperature or pain.

Question 19

Which sense monitors the position of your body in space and helps maintain balance?

Accepted Answer

The vestibular sense is responsible for monitoring the position and movement of the head, as well as maintaining balance.

Question 20

Sensations of hotness result from

Accepted Answer

Sensations of hotness can result from the paradoxical effect when both warm and cold receptors are simultaneously stimulated, leading to the perception of heat.
