Psychology- Memory and biology

STUDY
PLAY
action potential
A brief electrical charge that travels down the axon of a neuron
agonist
A drug that mimics the effects of a particular neurotransmitter or blocks its reuptake
axon
the extension of a neuron that carries messages away from the cell body
neurotransmitters
The chemical messengers released into the spatial junctions between neurons
dendrites
receive incoming signals from other neurons
endocrine system consists of a set of
glands
limbic system
drug cravings are likely in the reward centers of this system
corpus callosum
wide band of neural fibers that transmits information between the cerebral hemispheres.
The occipital lobes are to ________ as the temporal lobes are to ________.
seeing; hearing
After suffering an accidental brain injury, Kira has difficulty walking in a smooth and coordinated manner. It is most probable that she has suffered damage to her:
cerebellum.
hypothalamus
The limbic system structure that regulates hunger
frontal lobes
cerebral cortex is most directly involved in making plans and formulating moral judgments
Following massive damage to his frontal lobes, Phineas Gage was most strikingly debilitated by
irritablity
The _______ hemisphere typically excels in making subtle linguistic inferences and the _______ hemisphere typically excels in making quick, literal interpretations of language.
right; left
sensory memory
Storing an exact copy of incoming information for a few seconds; the first stage of memory
iconic memory
A fleeting mental image or visual representation (ex. lightening)
echoic memory
After a sound is heard, a brief continuation of the sound in the auditory system (ex. When your attention returns to class)
working memory
A newer understanding of short-term memory that involves conscious, active processing of incoming auditory and visual-spatial information, and of information retrieved from long-term memory
serial position effect
our tendency to
recall best the last and first items in a list, further illustrates the benefits of rehearsal.
explicit memory
refers to facts and experiences that one can consciously know and declare
implicit
involves learning an action while the individual does not know she knows.
threshold
the level of stimulation required to trigger a neural impulse.
synapse
the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron. The tiny gap at this junction is called the synaptic gap or cleft.
Neurotransmitters
(chemicals) released from the sending neuron travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing it to generate an action potential.
Somatic Nervous System
The division of the peripheral nervous system that controls the body's skeletal muscles. Intentional / conscious movements.
Autonomic Nervous System
Part of the PNS that controls the glands and other internal organs - heartbeat, digestion. Automatic / unconscious.
Adoptive parents are least likely to influence the ________ of their adopted children.
personality traits
Compared to women, men are ________ likely to feel comfortable about having casual sex with different partners and ________ likely to cite affection as a reason for their first sexual intercourse.
more; less
Intense and reactive infants become unusually anxious and aroused when facing new or strange situations. This best illustrates the importance of:
temperment
It has been suggested that men in all cultures tend to marry women younger than themselves because men are genetically predisposed to seek female features associated with youthful fertility. This suggestion best illustrates:
evolutionary perspective
At a social gathering, Latin Americans may behave in a manner that North Americans consider intrusive and overly expressive. This best illustrates the importance of being sensitive to differing:
norms
Concepts of maleness and femaleness that influence our perceptions are called gender:
schemas
Less than 10 percent of children's personality differences are attributable to the various ________ shared by family members.
backgrounds
The acquisition of a traditional masculine or feminine role is called:
gender-typing

smoking preferences on friendship choices.
The expectations that men initiate dates and that women select wedding gifts best illustrate aspects of:
gender roles
A measure of your memory in which you need to pick the correctly learned answer from a displayed list of options is known as a measure of:
recognition.
Many people can easily recall exactly what they were doing when they heard the news of the 9/11 terrorist tragedy. This best illustrates ________ memory.
flashbulb
When you have to make a long-distance call, dialing an unfamiliar area code plus a seven-digit number, you are likely to have trouble retaining the just-looked-up number. This best illustrates the limited capacity of ________ memory.
short-term

state-dependent memory.
Chunking
the organization of information into meaningful units.
meaningful encoding
In order to remember the information presented in her psychology textbook, Susan often relates it to her own life experiences. Susan's strategy is an effective memory aid because it facilitates:
Jamille performs better on foreign language vocabulary tests if she studies the material 15 minutes every day for 8 days than if she crams for 2 hours the night before the test. This illustrates what is known as:
the spacing effect

recall
a measure of memory in which the person need only identify times previously learned, as one a multiple choice test.
