STRAIGHTERLINE PSY120 FINAL PAPER 2026
FULL QUESTIONS AND CORRECT
ANSWERS
◉ science.
Answer: psychology uses systematic methods to observe human
behavior and draw conclusions
◉ behavior.
Answer: everything we do that can be directly observed
◉ mental process.
Answer: The thoughts, feelings, and motives that each of us
experiences privately but that cannot be observed directly
◉ critical thinking.
Answer: thinking that does not blindly accept arguments and
conclusions. Rather, it examines assumptions, discerns hidden
values, evaluates evidence, and assesses conclusions.
◉ empirical method.
,Answer: gaining knowledge through the observation of events, the
collection of data, and logical reasoning
◉ structuralism.
Answer: focus on identifying the elemental parts or structures of the
human mind; William Wundt
◉ functionalism.
Answer: 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
◉ natural selection.
Answer: 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.
Answer: a nerve cell; the basic building block of the nervous system
◉ glial cells.
Answer: cells in the nervous system that support, nourish, and
protect neurons
,◉ cell body.
Answer: Largest part of a typical neuron; contains the nucleus and
much of the cytoplasm
◉ dendrites.
Answer: Branchlike parts of a neuron that are specialized to receive
information.
◉ axon.
Answer: the extension of a neuron, ending in branching terminal
fibers, through which messages pass to other neurons or to muscles
or glands
◉ myelin sheath.
Answer: fatty layer that covers the axon of some neurons and helps
speed neural impulses
◉ resting potential.
Answer: The difference in electric charge between the inside and
outside of a neuron's cell membrane; neg inside, pos outisde
◉ action potential.
Answer: a neural impulse; a brief electrical charge that travels down
an axon
, ◉ all or nothing principle.
Answer: 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.
Answer: tiny gaps between dentrites and axons of different neurons
◉ Neuraltransmitters.
Answer: transmit, or carry, information across the synaptic gap to
the next neuron
◉ Acetylcholine (ACh).
Answer: stimulates the firing of neurons and is involved in the action
of muscles, learning, and memory
◉ Alzheimer's disease.
Answer: degenerative brain disorder that involves a decline in
memory, have an acetylcholine deficiency
◉ GABA.
Answer: a major inhibitory neurotransmitter
