Psychology
which of the following is most useful for helping survey researchers avoid false generalizations
random sampling

clear memory of an emotionally significant moment or event
to discover the extent to which economic status can be used to predict political preferences, researchers are most likely to use
correlational measures
parkinson's disease is associated with shortage of
dopamine
norepinephrine
helps control alertness and arousal (undersupply = depressed mood)
the chemical messengers released into the spatial junctions between neurons are called
neurotransmitters
storage
process of retaining encoded info over time
hippocampus
processes explicit memories for storage
somatosensory cortex
registers and processes body touch and movement sensations
medulla
the base of the brainstem; controls heartbeat and breathing
glutamate
a major excitatory neurotransmitter; involved in memory (oversupply = overstimulated brain, producing migraines or seizures)
the case study is a research method in which
a single indiv. is studies in depth
serotonin
affects mood, huner, sleep, and arousal (undersupply = depression)
endorphins
explains "runner's high" or the painkilling effects of acupuncture, the indifference to pain in some severely injured people
cerebral cortex
intricate fabric of interconnected neural cells covering the cerebral hemispheres; body's ultimate control and info-processing center
amygdala
linked to emotion; 2 lima bean structures
pituitary glands
under the influence of the hypothalamus, regulates growth and controls other endocrine glands
dopamine
influences movement, learning, attention, and emotion (under supply = parkinson's disease, oversupply = schizophrenia)
the localization of a function such as speech production to the right or the left side of the brain is called
lateralization
the function of dendrites is to
receive incoming signals from other neurons
parietal lobes
receives sensory input for touch and body position
reflex
simple, automatic response to a sensory stimulus, such as the knee-jerk response
psychology
study of mental/behavioral process
encoding
processing of info into the memory system
jose has just played a long, bruising football game but feels little fatigue or discomfort. his lack of pain is most likely caused by the release of
endorphins
which technique involves repeating the essence of an earlier research study w diff participants and in diff cirumstance
replication
a hypothesis is a(n)
testable prediction that gives direction to research
occipital lobes
includes areas that receive info from the visual fields
acetylcholine
enables muscle action, learning, and memory (alzheimer's disease)
pons
helps coordinate movement and control sleep
frontal lobes
involved in speaking and muscle movements and in making plans and judgments
which of the following is the component of the limbic system that plays an essential role in the processing of new memories a. hypothalamus b. thalamus c. hippocampus d. medulla
C HIPPOCAMPUS
motor cortex
area at the rear of frontal lobes that controls voluntary movements
association areas
areas of the cerebral cortex that are not involved in primary motor or sensory functions; involved in higher mental functions such as learning, remembering, thinking, speaking
which of the following body parts is associated with the greatest amount of brain tissue in the motor cortex? a. arms. b. face c. trunk d. knees
b. face
proactive interference
forward-acting disruptive effect of prior learning on the recall of new info
the corpus callosum is a wide band of axon fibers that
transmits info between the cerebral hemispheres
drugs to treat alzheimer's disease slow the breakdown of
actylcholine
retroactive interference
backward-acting disruptive effect of new learning on the recall of old info
thalamus
brain's sensory control center, located on top of the brainstem; directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla
Addictive disorders are likely to be associated with reward centers in the a. thalamus b. cerebellum c. reticular formation d. limbic system
d limbic system
in a psychological experiment, the factor that may be influenced by the manipulated experimental treatment is called the _______ variable
dependent
sensory memory
immediate, very brief recording of sensory info in the memory system
corpus callosum
large band of fibers connecting the 2 brain hemispheres and carrying messages between them
GABA
major inhibitory neurotransmitter (oversupply = seizures, tremors, insomnia) f
brain stem
oldest part and central core of the brain, beginning where the spinal cord swells as it enters the skull; responsible for automatic survival functions
adrenal glands
pair of endocrine glands that sit above the kidneys and secrete epinephrine and norepinephrine that helps arouse the body in times of STRESS
reconsolidation
process in which previously stored memories, when retrieved, are potentially altered before being stored again.
retrieval
process of getting info out of memory storage
cerebellum
processes sensory input, coordinating movement output and balance, and enabling nonverbal learning and memory
when an eyewitness to an auto accident is asked to desribe what happened, whcih test of memory is being used
recall
the magical nymber seven, plys or minus two, refers to the storage capacity of ________ memory
short-term
repression
the basic defense mechanism that banishes from consciousness anxiety-arousing thoughts, feelings, and memories
sympathetic nervous system
the division of the automatic nervous system that arouses the body, mobilizing its energy
parasympathetic nervous system
the division of the automatic nervous system that calms the body, conserving its energy
long-term memory
the relatively permanent and limitless storehouse of the memory system; includes knowledge, skills, and experience
hypothalamus
directs several maintenance activities (eating, drinking, body temp); emotion and reward (remember: rats kept wanting reward to hypothalamus)
temporal lobes
each receiving info primarily from opposite side; includes auditory areas
statistical significant
a statistical statement of how likely it is that an obtained result occurred by chance
short-term memory
activated memory that holds a few items briefly, before the info is stored or forgotten
reticular formation
nerve network that travels through the brainstem into the thalamus and plays an important role in controlling arousal
limbic system
neural system (hippocampus, amygdala, hypothalamus); associated with emotions and drives
to decide whether observe diff between samples reflect actual diff between pop, you should determine the _____ of the observed diff
statistical significance
