PSYCH UNIT 2 TEST
Sleep deprivation increases levels of the hunger-arousing hormone
ghrelin.
The endocrine system consists of
glands
An experienced tennis player's brain and body respond with skilled accuracy to an oncoming serve before the person becomes consciously aware of the ball's trajectory. This best illustrates the value of
a two-track mind.
Alpha waves are associated with
a relaxed but awake state.
The vast majority of neurons in the body's information system are
interneurons.
The right hemisphere of Julie's brain is better than her left hemisphere at recognizing facial expressions of emotion. This best illustrates
lateralization.
The brain devotes more tissue within the ________ for body areas requiring the most precise movement control, such as the fingers.
motor cortex
Neurons that enable people to throw a baseball by relaying messages from their central nervous system to their skeletal muscles are called
motor neurons.
While listening to operatic solos, musicians process the lyrics and the tunes in separate brain areas. This most clearly illustrates the functioning of different
neural networks.
The processing of information on many parallel tracks at the same time is a skill most closely associated with
unconscious mental activity.
A recurring sleep stage during which most vivid dreams commonly occur is known as ________ sleep.
REM
Which of the following would be particularly useful for detecting the brain areas that are most active as a person performs mathematical calculations?
a PET scan
The messages neurons carry are nerve impulses called
action potentials.
The regions of the parietal lobes that are involved in mathematical and spatial reasoning are known as
association areas.
The brain's oldest region is the
brain stem
A neuron is best described as a
cell
After suffering an accidental brain injury, Kira has difficulty walking in a smooth and coordinated manner. She has probably suffered damage to her
cerebellum.
Coordinated brain-wide activity is a sign of
conscious awareness.
Natural, opiate-like neurotransmitters linked to pain control are called
endorphins
Which portion of the cerebral cortex is most directly involved in making plans and formulating moral judgments?
frontal lobes
The limbic system's hippocampus
helps process explicit memories for storage.
The limbic system structure that regulates hunger is called the
hypothalamus.
In one experiment, many of the research participants who were keeping track of basketball tosses between players failed to notice a gorilla-suited research assistant thumping his chest as he moved among the players. This failure best illustrated
inattentional blindness.
Bright light inhibits our feelings of sleepiness by influencing the production of
melatonin.
Which hormone enables contractions associated with birthing and milk flow during nursing?
oxytocin
Karen's years of experience navigating the streets of a very large city as a taxi driver have resulted in changes in her brain's spatial memory centers that support her detailed street location memory. This best illustrates the value of
plasticity.
Activation of the sympathetic nervous system ________ blood sugar levels and ________ the pupils of the eyes.
raises; dilates
The distinction between manifest content and latent content is central to an explanation of dreams that emphasizes
satisfaction of one's own wishes.
A teenager focused on texting while crossing the street is not likely to notice a car rounding the corner and about to cross her path. This best illustrates the unfortunate consequences of
selective attention.
Which of the following sleep disorders is most strongly associated with obesity?
sleep apnea
Drugs that block the reuptake of serotonin will thereby increase the concentration of serotonin molecules in the
synaptic gaps.
Which brain structure relays information from the eyes to the visual cortex?
thalamus
Staying up especially late on weekends is most likely to have an influence on
the circadian rhythm.
