AP Psychology Examination sample prep Questions and
Answers; certified for accuracy 2025/2026
Hippocampus - correct answer A structure in the forebrain associated with
the formation of new memories.
Cerebral Cortex - correct answer The outer surface of the brain
Corpus Callosum - correct answer A massive bundle of fibers that connects
the right and left cerebral hemispheres and allows them to communicate with
each other.
Dopamine - correct answer A neurotransmitter used in the parts of the brain
involved in regulating movement and experiencing pleasure.
Serotonin - correct answer A neurotransmitter used by cells in parts of the
brain involved in the regulation of sleep, mood, and eating.
Sensations - correct answer Messages from the senses that make up the
raw information that affects many kinds of behavior and mental processes.
Amplitude - correct answer The difference between the peak and the
baseline of a waveform.
Wavelength - correct answer The distance from one peak to the next in a
waveform
Frequency - correct answer The number of complete waveforms, or cycles,
that pass by a given point in space every second.
, Cornea - correct answer The curved, transparent, protective layer through
which light rays enter the eye.

photoreceptors in the retina that allow vision even in dim light.
Cones - correct answer Photoreceptors in the retina that help us to
distinguish colors.
Blind Spot - correct answer The light-insensitive point at which axons from
all of the ganglion cells converge and exit the eyeball
