    Perhaps the best known hallucinogen is

    • cocaine.

    • Alcohol.

    • LSD.

    • Nicotine

    Correct Answer
    A. LSD.
    Explanation
    LSD is the best known hallucinogen because it gained significant popularity during the counterculture movement in the 1960s. It became associated with the hippie movement and was widely used for its psychedelic effects. LSD is a powerful hallucinogenic drug that alters perception, thoughts, and feelings. It is known for producing intense visual hallucinations and can cause profound changes in consciousness. Its widespread use and cultural impact have made it the most well-known hallucinogen.

    Substances capable of altering human consciousness are classified as

    • pharmacologic drugs.

    • Addictive.

    • Psychoactive drugs.

    • narcotics

    Correct Answer
    A. Psychoactive drugs.
    Explanation
    Pharmacologic drugs refer to substances that have an effect on the body and its functions. While addictive substances can also alter human consciousness, the term "pharmacologic drugs" is a broader classification that includes both addictive and non-addictive substances. Narcotics specifically refer to drugs that have pain-relieving properties. Therefore, the most appropriate classification for substances capable of altering human consciousness is "psychoactive drugs," as they directly affect the brain and can change perception, mood, and behavior.

    The chief characteristic of hypnosis is

    • heightened arousal.

    • increased suggestibility.

    • Enhanced creativity.

    • Increased clairvoyance

    Correct Answer
    A. increased suggestibility.
    Explanation
    Hypnosis is known for inducing a state of heightened suggestibility in individuals. During hypnosis, a person becomes more open and receptive to suggestions and instructions given by the hypnotist. This increased suggestibility allows the hypnotist to influence the individual's thoughts, feelings, and behaviors in a way that they may not be able to do in their normal waking state. Therefore, the correct answer is increased suggestibility.

    A sleep disturbance in which one awakens several times during the night and has difficulty returning to sleep is

    • narcolepsy.

    • sleep apnea.

    • somnambulism.

    • Insomnia.

    Correct Answer
    A. Insomnia.
    Explanation
    Insomnia is the correct answer because it refers to a sleep disturbance where a person wakes up multiple times during the night and has difficulty falling back asleep. Narcolepsy is a sleep disorder characterized by excessive daytime sleepiness and sudden attacks of sleep. Sleep apnea is a disorder where a person's breathing is interrupted during sleep. Somnambulism, also known as sleepwalking, is a sleep disorder where a person engages in activities while asleep.

    According to Freud, dreams are very often a means of

    • Wish fulfillment.

    • Solving daytime problems

    • Telling oneself what's missing in one's life.

    • Categorizing one's experience.

    Correct Answer
    A. Wish fulfillment.
    Explanation
    Freud believed that dreams serve as a way for individuals to fulfill their unconscious wishes and desires that are not fulfilled in their waking life. Dreams allow individuals to experience and satisfy their deepest desires and fantasies. This theory suggests that dreams are a reflection of our unconscious mind and provide insight into our hidden desires and motivations.

    Rate this question:

  • 7. 

    Which stage of sleep typically has spindles?

    • First

    • Second

    • Third

    • Fourth

    Correct Answer
    A. Second
    Explanation
    The second stage of sleep typically has spindles. Spindles are brief bursts of rapid brain activity that last for a few seconds. They are characterized by a distinctive wave pattern on an electroencephalogram (EEG). During this stage, the body starts to relax even more, heart rate and body temperature decrease, and the brain waves become slower with occasional bursts of rapid activity. This stage is important for transitioning from light sleep to deeper sleep.

    Dissociation or a split in awareness is an experience commonly associated with

    • Hypnotic induction.

    • Amphetamine intoxication.

    • withdrawal symptoms.

    • relaxation training.

    Correct Answer
    A. Hypnotic induction.
    Explanation
    Dissociation or a split in awareness is commonly associated with hypnotic induction. This process involves inducing a trance-like state where the individual becomes highly focused and detached from their surroundings. During this state, they may experience a dissociation or a split in awareness, where they feel detached from their body or have an altered sense of time. This is a key characteristic of hypnotic induction and is not typically associated with amphetamine intoxication, withdrawal symptoms, or relaxation training.

  • 9. 

    The reduction in the body's response to a drug which may accompany drug use is called

    • Withdrawal.

    • Addiction

    • Dependence.

    • Tolerance.

    Correct Answer
    A. Tolerance.
    Explanation
    Tolerance refers to the reduction in the body's response to a drug that can occur with repeated use. This means that over time, a person may need to take higher doses of the drug in order to achieve the same effect that was initially experienced with a lower dose. Withdrawal, addiction, and dependence are related concepts, but they do not specifically refer to the reduction in the body's response to a drug.

    Rate this question:

  • 10. 

    Our sleep rhythms are tied to a 24-hour day because

    • The time of peak activity is invariant from person to person.

    • They are tied to external time markers like light and dark.

    • They have adapted to technological improvements made in the last century.

    • Everyone needs at least 8 hours of sleep every night.

    Correct Answer
    A. They are tied to external time markers like light and dark.
    Explanation
    Our sleep rhythms are tied to external time markers like light and dark. This is because our bodies have evolved to be synchronized with the natural light-dark cycle of the 24-hour day. Light exposure, particularly in the morning, helps regulate our internal body clock and signals to our brain when it is time to be awake and alert. Darkness, on the other hand, triggers the release of melatonin, a hormone that promotes sleep. This synchronization with external time markers helps to regulate our sleep-wake cycles and maintain a consistent pattern of sleep.

  • 11. 

    Which of the following is classified as a stimulant?

    • alcohol

    • Cocaine

    • Marijuana

    • Morphine

    Correct Answer
    A. Cocaine
    Explanation
    Cocaine is classified as a stimulant because it increases the activity of the central nervous system, resulting in increased alertness, energy, and euphoria. It works by blocking the reuptake of certain neurotransmitters, such as dopamine, norepinephrine, and serotonin, leading to their increased levels in the brain. This stimulation can have various effects on the body, including increased heart rate, blood pressure, and body temperature. In contrast, alcohol, marijuana, and morphine are classified as depressants because they slow down the activity of the central nervous system, leading to relaxation, sedation, and decreased cognitive function.

    Rate this question:

  • 12. 

    Nicotine is classified as a

    • narcotic.

    • depressant.

    • Relaxant.

    • Stimulant.

    Correct Answer
    A. Stimulant.
    Explanation
    Nicotine is classified as a stimulant because it increases the activity of the central nervous system, leading to increased heart rate, blood pressure, and alertness. It also enhances the release of dopamine in the brain, which produces feelings of pleasure and reward. These effects make nicotine a stimulant drug that can increase focus, attention, and arousal.

    Physical cravings for a drug and unpleasant reactions when the drug is withheld are signs of

    • Drug tolerance.

    • psychological dependence.

    • Emotional dependence.

    • Physical addiction.

    Correct Answer
    A. Physical addiction.
    Explanation
    Physical cravings for a drug and unpleasant reactions when the drug is withheld are characteristic symptoms of physical addiction. Physical addiction refers to the body's physical dependence on a drug, where the body becomes tolerant to the drug and requires increasing amounts to achieve the same effect. When the drug is withheld, withdrawal symptoms occur, which can include physical cravings and unpleasant reactions. Psychological dependence and emotional dependence, on the other hand, refer to the mental and emotional reliance on a drug, rather than the physical symptoms experienced.

    Some physicians believe that SIDS, or crib death, may be caused by

    • prematurity.

    • Sleep apnea.

    • Narcolepsy.

    • Snoring.

    Correct Answer
    A. Sleep apnea.
    Explanation
    Sleep apnea is a sleep disorder characterized by pauses in breathing or shallow breaths during sleep. It has been suggested by some physicians that SIDS, or crib death, may be caused by sleep apnea. This is because sleep apnea can lead to a decrease in oxygen levels in the body, which can be harmful and potentially fatal, especially in infants. Therefore, sleep apnea is a plausible explanation for SIDS, making it the correct answer.

    Beta waves are characteristic in the EEG of a person who is

    • dreaming.

    • Asleep but not dreaming.

    • Awake and alert.

    • In Stage 2 sleep.

    Correct Answer
    A. Awake and alert.
    Explanation
    Beta waves are high-frequency brain waves that are typically associated with a state of wakefulness and alertness. These waves are commonly observed when a person is engaged in active mental activity, such as problem-solving or focused attention. Therefore, the presence of beta waves in an EEG suggests that the person is awake and alert rather than asleep or dreaming.

  • 16. 

    That there is a need for REM sleep is suggested by

    • REM rebound.

    • REM tolerance.

    • Eye movements accompanying REM sleep.

    • Emotional catharsis during REM sleep.

    Correct Answer
    A. REM rebound.
    Explanation
    The fact that there is a need for REM sleep is suggested by REM rebound. REM rebound refers to the phenomenon where a person experiences an increase in REM sleep after a period of REM sleep deprivation. This suggests that the body has a biological need for REM sleep and tries to make up for the lost REM sleep when given the opportunity.

    Night terrors most often occur during

    • Stage 1 NREM sleep.

    • Stage 2 REM sleep.

    • Stage 3 NREM sleep.

    • Stage 4 NREM sleep.

    Correct Answer
    A. Stage 4 NREM sleep.
    Explanation
    Night terrors most often occur during Stage 4 NREM sleep. This stage is characterized by deep sleep, and night terrors usually occur during the transition from this stage to waking up. During Stage 4 NREM sleep, the brain is less responsive to external stimuli, making it more likely for night terrors to occur without being easily awakened. Additionally, Stage 4 NREM sleep is associated with the occurrence of sleepwalking and sleep talking, which are often seen in individuals who experience night terrors.

  • 18. 

    During hypnosis, EEG (brain-wave) recordings

    • resemble those obtained during sleep.

    • Resemble those obtained when a person is awake.

    • Slow almost to a stop.

    • show clearly identifiable "trance waves."

    Correct Answer
    A. Resemble those obtained when a person is awake.
    Explanation
    During hypnosis, EEG recordings resemble those obtained when a person is awake because hypnosis is a state of focused attention and heightened suggestibility, rather than a state of sleep. The brain waves during hypnosis are similar to those when a person is awake, indicating that the individual is in a wakeful and receptive state of mind. This suggests that hypnosis involves a different state of consciousness than sleep, as the brain activity is different.

    Rate this question:

  • 19. 

    Immediately before sleep the EEG shifts to patterns of larger and slower waves called __________ waves.

    • Alpha

    • Beta

    • delta

    • Spindle

    Correct Answer
    A. Alpha
    Explanation
    During the transition from wakefulness to sleep, the brain's electrical activity, as measured by EEG, changes. Specifically, immediately before sleep, the EEG shows patterns of larger and slower waves called alpha waves. These alpha waves are associated with a relaxed and drowsy state, indicating that the individual is entering a state of sleep.

    Drugs with names like Xanax, Halcion, and Valium are

    • Barbiturates.

    • Stimulants.

    • Hallucinogens.

    • Tranquilizers.

    Correct Answer
    A. Tranquilizers.
    Explanation
    Drugs with names like Xanax, Halcion, and Valium are tranquilizers. Tranquilizers are a type of medication that is commonly used to treat anxiety, insomnia, and other related conditions. They work by depressing the central nervous system, producing a calming and sedating effect. Barbiturates, on the other hand, are a class of drugs that act as central nervous system depressants and are used as sedatives or hypnotics. Stimulants are drugs that increase alertness, attention, and energy. Hallucinogens are a class of drugs that alter perception, thoughts, and feelings, often causing hallucinations.
