Question 1

Rowena is placed in a room and told to press a button each time she hears a sound become louder.In this test, Rowena's _____ is being measured.
A)difference threshold for sound
B)adaptation threshold for sound
C)absolute threshold for sound
D)level of auditory accommodation

Accepted Answer

The difference threshold, also known as the just noticeable difference (jnd), is the minimum difference in stimulation that a person can detect 50 percent of the time. In this scenario, Rowena is asked to press a button each time she perceives a change in the loudness of a sound, which directly relates to her ability to detect the difference in sound intensity, hence measuring her difference threshold for sound.

Question 2

A subliminal stimulus refers to any stimulus that _____.
A)is presented during a person's motivational need state
B)manipulates people without their knowing about it
C)is presented below the absolute threshold of a person's conscious awareness
D)goes undetected in more than 50% of its presentations

Accepted Answer

A subliminal stimulus is one that is presented below the absolute threshold of a person's conscious awareness, meaning it is not consciously detected.

Question 3

Sensory reduction refers to the process of _____.
A)reducing your dependence on a single sensory system
B)decreasing the number of sensory receptors that are stimulated
C)filtering and analyzing incoming sensations before sending a neural message to the cortex
D)reducing environmental sensations by physically preventing your sensory organs from seeing or hearing.

Accepted Answer

Sensory reduction involves filtering and analyzing incoming sensory information before it is sent to the brain's cortex, allowing the brain to focus on important stimuli and ignore irrelevant background noise.

Question 4

The difference threshold is the minimal _____.
A)physical difference needed to notice a change between two stimuli
B)stimulus energy that can be detected by different people
C)stimulus energy that can be detected at different times by the same person
D)difference needed to determine which senses are involved in a multisensory experience

Accepted Answer

The difference threshold, also known as the just noticeable difference (jnd), is the minimum amount of change needed in a stimulus for a person to detect a difference between it and another stimulus.

Question 5

The reason you are seeing this test, rather than smelling it, tasting it, or hearing it, is because your visual receptors are being stimulated and the information is being sent along the optic nerve to the occipital lobe in your brain.This process is called _____.
A)transduction
B)sensory reduction
C)transformation
D)coding

Accepted Answer

The answer of The reason you are seeing this test,...

Question 6

Jose twists his ankle quite badly in the last ten minutes of his school's championship soccer game.He continues to play and does not notice the pain in his ankle.This is probably because of an increase in his _____ levels.
A)testosterone
B)adrenalin
C)epinephrine
D)endorphin

Accepted Answer

Endorphins are natural painkillers produced by the body, which can also produce a feeling of euphoria. They are likely responsible for Jose not noticing the pain in his ankle, as they can be released in response to stress or pain, helping to mask the discomfort.

Question 7

The smallest magnitude of a particular stimulus energy that can be detected 50% of the time is called its _____ threshold.
A)signal
B)difference
C)absolute
D)detection

Accepted Answer

The smallest magnitude of a particular stimulus energy that can be detected 50% of the time is called its absolute threshold. This concept is fundamental in sensory psychology, referring to the minimum intensity of a stimulus that one can detect.

Question 8

Scientists use a(n)_____ to flash images too quickly for conscious recognition, but slowly enough to be registered.
A)osciloscopio
B)sensorscope
C)tachistoscope
D)sublimascope

Accepted Answer

A tachistoscope is used to flash images at a speed too quick for conscious recognition but slow enough for the brain to register them. This tool is often used in psychological experiments to study perception and memory.

Question 9

Which of the following is NOT prone to complete sensory adaptation?
A)Vision
B)Taste
C)Smell
D)Touch

Accepted Answer

Vision does not undergo complete sensory adaptation because the eyes constantly make small movements called saccades, preventing the visual sensory cells from fully adapting to a constant stimulus. This ensures that we continue to perceive visual stimuli over time.

Question 10

Which of the following neurotransmitters act(s)like morphine to inhibit pain perception?
A)GABA
B)Epinephrine
C)Endorphins
D)Norepinephrine

Accepted Answer

Endorphins act like morphine to inhibit pain perception by interacting with the opiate receptors in the brain to reduce our perception of pain and act similarly to drugs such as morphine and codeine.

Question 11

Caleb and Amara sleep through a passing police siren and the blaring of their neighbor's stereo, but wake instantly when their newborn baby begins to whimper softly.This is an example of _____.
A)sensory reduction
B)parenting
C)sensory analysis
D)sensory adaptation

Accepted Answer

The answer of Caleb and Amara sleep through a passing...

Question 12

Your friend is thinking of using several subliminal tapes to improve his memory and self-esteem.He asks you what psychologists think about these tapes.What would be the MOST correct response you could make?
A)They provide a convenient and generally reliable form of self-help.
B)They promote mental and physical health.
C)They have been shown to be highly effective for some people.
D)They are not supported by scientific research.

Accepted Answer

Subliminal tapes have not been supported by scientific research in terms of their effectiveness for improving memory, self-esteem, or other psychological aspects. Studies have generally failed to show that these tapes have the claimed benefits, leading the scientific community to view them skeptically.

Question 13

When you first put your clothes on this morning you felt them on your skin, but within minutes you no longer noticed them.This is an example of _____.
A)sensory accommodation
B)sensory adaptation
C)feature detectors
D)habituation

Accepted Answer

This phenomenon is known as sensory adaptation, where the sensory receptors become less responsive to constant stimuli, leading to a decrease in the sensation over time.

Question 14

A phenomenon in which the perceived intensity of a repeated stimulus decreases over time is called sensory_____.
A)coding
B)assimilation
C)accommodation
D)adaptation

Accepted Answer

Sensory adaptation refers to the process by which the perceived intensity of a stimulus decreases when that stimulus is repeatedly presented. It's a form of neural adaptation that allows organisms to become less sensitive to constant stimuli, helping to focus on changes in the environment.

Question 15

These senses adapt most quickly to repeated stimulation.
A)smell and touch
B)vision and touch
C)vision and pain
D)smell and hearing

Accepted Answer

Smell and touch are the senses that adapt most quickly to repeated stimulation. This adaptation allows the brain to filter out non-essential information and focus on changes in the environment.

Question 16

The branch of psychology that studies the relation between attributes of the physical stimuli and our sensory experience of those attributes is called _____.
A)physical psychology
B)astropsychology
C)parapsychology
D)psychophysics

Accepted Answer

Psychophysics is the branch of psychology that studies the relationship between the physical characteristics of stimuli and the sensations and perceptions they evoke in a viewer.

Question 17

Dr.Shiguli wants to determine the lightest touch that can be felt by various animals compared to human beings.He would therefore be interested in finding the _____ threshold for touch.
A)absolute
B)difference
C)human
D)perception

Accepted Answer

The absolute threshold refers to the minimum intensity of stimulus that can be detected by the sensory receptors, which in this case relates to the lightest touch that can be felt.

Question 18

Using a headset that blocks auditory impulses from being sent to the brain to you sleep better works by _____.
A)sensory deprivation
B)sensory reduction
C)sensory elimination
D)coding

Accepted Answer

Using a headset that blocks auditory impulses from being sent to the brain to help you sleep better works by sensory reduction. This method reduces the amount of sensory input to the brain, rather than eliminating it entirely or depriving the senses in a more general sense.

Question 19

Experiments on subliminal perception have _____.
A)supported the existence of the phenomenon, but found it has little or no effect on persuasion
B)shown that subliminal perception occurs only among children and some adolescents
C)shown that subliminal messages affect only people who are highly suggestible
D)failed to support the phenomenon

Accepted Answer

Subliminal perception is a concept that suggests stimuli can influence our thoughts, feelings, or actions without us being consciously aware of them. Research in psychology has supported the existence of subliminal perception but has generally found that its effects on persuasion are minimal or negligible. This means that while subliminal messages can be perceived at some level below conscious awareness, they do not significantly alter people's attitudes or behaviors in the way that some might expect or fear.

Question 20

Our senses adapt to continuous, repetitive stimulation because this allows us to _____.
A)focus on more important, immediate stimuli
B)relax due to familiarity
C)multitask effectively
D)disregard things we never should have paid attention to in the first place

Accepted Answer

Our senses adapt to continuous, repetitive stimulation to help us focus on more important, immediate stimuli, ensuring that our attention is not constantly drawn to unchanging background information. This adaptation allows us to prioritize new and potentially important changes in our environment.
