QUIZ 3 Flashcards
Interocular Suppression
an image presented to one eye suppresses another image presented to the other eye
Mind Wandering
state of consciousness in which random (purposeless) flow of thoughts comes to mind
Default Mode Network (DMN)
activations of brain areas when people daydream
Freudian Slip
when an unconscious (typically suppressed, according to Freud) though is suddenly expressed at an inappropriate time or in an inappropriate social context
Modern Take on Freudian Slip
some reveal unconscious thoughts & desires but many cases are simply cases of misremembering, mis-retrieval, lapses, language mistakes

Stages of Sleep (5)
- dozing off
- light sleep
- deep sleep
- deeper sleep
- REM sleep
Freud’s View of Why We Dream
dream hold meaning (represent hidden wishes/anxiety), represent inappropriate thoughts
Activation Synthesis Model
brain imposes meaning on random neural activity, dreams produced when brain attempts to make sense of activation that occur randomly during sleep
What is the difference between the Freud’s theory and the Activation Synthesis Model?
In Freud’s theory, dreams begin with meaning, whereas in the activation-synthesis theory, dreams begin randomly, then meaning can be added
Types of Psychoactive Drugs (4)
Depressants, Stimulants, Narcotics, Hallucinogens
Expectancy Theory
alcohol effect can be produced by people’s expectations of how alcohol will influence them in particular situations
Alcohol Myopia Theory
alcohol hampers attention, leading people to respond in simple ways to complex situation
Depressants
reduce CNS activity, increase activity of neurotransmitter GABA (alcohol, king of depressants)
Stimulants
substances that excite the CNS, heightening arousal & activity levels, increase levels of dopamine & norepinephrine in brain (caffeine, amphetamines, nicotine, cocaine)
Narcotics
highly addictive drugs derived from opium that relieve pain (heroin, morphine, codeine)
Hallucinogens
drugs that alter sensation & perception; often cause visual & auditory hallucinations (LSD, Ketamine)
Unresponsive Wakefulness Syndrome
when people emerge from a coma; their eyes open; have sleep/wake cycles; do not respond to external stimuli for more than a month; still activity in regions of brain stem; vegetative state
Minimally Conscious State
when people emerge from a coma; make deliberate movements (following object with eyes
Brain Death
irreversible loss of brain function; no brain activity
Locked-in Syndrome
full awareness but cannot demonstrate it (no voluntary muscles), not consciousness problem, problem with muscles
Encoding
transforming what we perceive, think, or feel into an enduring memory
Storage
