PSY 101 STRAIGHTLINER FINAL EXAM LATEST UPDATES -
2025/2026- ACTUAL QUESTIONS WITH VERIFIED ANSWERS
ALREADY GRADED A+ GUARANTEED SUCCESS
structuralism
focus on identifying the elemental parts or structures of the human mind; William
Wundt
functionalism
A school of psychology that focused on how our mental and behavioral processes
function - how they enable us to adapt, survive, and flourish; William James
behavior
everything we do that can be directly observed
mental process
The thoughts, feelings, and motives that each of us experiences privately but that
cannot be observed directly
critical thinking
thinking that does not blindly accept arguments and conclusions. Rather, it
examines assumptions, discerns hidden values, evaluates evidence, and assesses
conclusions.
empirical method
gaining knowledge through the observation of events, the collection of data, and
logical reasoning
natural selection
, 2
A process in which individuals that have certain inherited traits tend to survive
and reproduce at higher rates than other individuals because of those traits;
Charles Darwin
neurons
a nerve cell; the basic building block of the nervous system
glial cells
cells in the nervous system that support, nourish, and protect neurons
cell body
Largest part of a typical neuron; contains the nucleus and much of the cytoplasm
dendrites
Branchlike parts of a neuron that are specialized to receive information.
axon
the extension of a neuron, ending in branching terminal fibers, through which
messages pass to other neurons or to muscles or glands
myelin sheath
fatty layer that covers the axon of some neurons and helps speed neural impulses
resting potential
The difference in electric charge between the inside and outside of a neuron's cell
membrane; neg inside, pos outisde
action potential
a neural impulse; a brief electrical charge that travels down an axon
all or nothing principle
The principle that once the electrical impulse reaches a certain level of intensity
(its threshold), it fires and moves all the way down the axon without losing any
intensity.
synapses
, 3
tiny gaps between dentrites and axons of different neurons
Neuraltransmitters
transmit, or carry, information across the synaptic gap to the next neuron
Acetylcholine (ACh)
stimulates the firing of neurons and is involved in the action of muscles, learning,
and memory
Alzheimer's disease
degenerative brain disorder that involves a decline in memory, have an
acetylcholine deficiency
GABA
a major inhibitory neurotransmitter
decreased GABA levels
lead to anxiety
glutamate
exciting many neurons to fire and is especially involved in learning and memory
norepinephrine
inhibits the firing of neurons in the central nervous system, but it excites the
heart muscle, intestines, and urogenital tract
dopamine
control voluntary movement and affects sleep, mood, attention, learning, and the
ability to recognize rewards in the environment
seratonin
involved in the regulation of sleep, mood, attention, and learning
endorphins
natural opiates that mainly stimulate the firing of neurons; block pain & increase
pleasure
