audition - ANS the sense or act of hearing
autism - ANS a disorder that appears in childhood and is marked by deficient communication,
social interaction, and understanding of others' states of mind
automatic processing - ANS unconscious encoding of incidental information, such as space,
time, and frequency, and of well-learned information, such as word meanings
autonomic nervous system - ANS the part of the peripheral nervous system that controls the
glands that the muscles of the internal organs. Its sympathetic division arouses; its
parasympathetic division calms
availability heuristic - ANS estimating the likelihood of events based on their availability in
memory; if instances come readily to mind, we presume such events are common
aversive conditioning - ANS a type of counterconditioning that associates an unpleasant state
(such as nausea) with an unwanted behavior (such as drinking)

messages pass to other neurons or to muscles or glands
babbling stage - ANS beginning at about 4 months, the stage of speech development in which
the infant spontaneously utters various sounds at first unrelated to household language
barbituarates - ANS drugs that depress the activity of the centeral nervous system, reducing
anxiety but imparing memory and judgment
