chapter 6 Flashcards
type of relatively low frequency, relatively high amplitude brain wave that becomes synchronized; characteristic of the beginning of stage 1 sleep
alpha wave
internal cycle of biological activity
biological rhythm
lack of muscle tone or muscle weakness, and in some cases complete paralysis of the voluntary muscles
cataplexy
sleep disorder with periods of interrupted breathing due to a disruption in signals sent from the brain that regulate breathing
central sleep apnea
biological rhythm that occurs over approximately 24 hours
circadian rhythm
opiate with relatively low potency often prescribed for minor pain
codeine
psychotherapy that focuses on cognitive processes and problem behaviors that is sometimes used to treat sleep disorders such as insomnia
cognitive-behavioral therapy
theoretical repository of information shared by all people across cultures, as described by Carl Jung
collective unconscious
awareness of internal and external stimuli
consciousness
device used to treat sleep apnea; includes a mask that fits over the sleeper’s nose and mouth, which is connected to a pump that pumps air into the person’s airways, forcing them to remain open
continuous positive airway pressure (CPAP)
the process in which individuals attend to many sources of information at once
divided attention
type of low frequency, high amplitude brain wave characteristic of stage 3 and stage 4 sleep
delta wave
drug that tends to suppress central nervous system activity
depressant
feelings of intense elation and pleasure from drug use
euphoric high
discipline that studies how universal patterns of behavior and cognitive processes have evolved over time as a result of natural selection
evolutionary psychology
one of a class of drugs that results in profound alterations in sensory and perceptual experiences, often with vivid hallucinations
hallucinogen
tendency to maintain a balance, or optimal level, within a biological system
homeostasis
state of extreme self-focus and attention in which minimal attention is given to external stimuli
hypnosis
consistent difficulty in falling or staying asleep for at least three nights a week over a month’s time
insomnia
collection of symptoms brought on by travel from one time zone to another that results from the mismatch between our internal circadian cycles and our environment
jetlag
very high amplitude pattern of brain activity associated with stage 2 sleep that may occur in response to environmental stimuli
K-complex
hidden meaning of a dream, per Sigmund Freud’s view of the function of dreams
latent content
people become aware that they are dreaming and can control the dream’s content
lucid dream
storyline of events that occur during a dream, per Sigmund Freud’s view of the function of dreams
manifest content
