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.
