Exam 3 Flashcards
consciousness
our subjective awareness of ourselves and our environment
change blindness
failure to notice changes in the environment; a form of inattentional blindness.
dual processing
the principle that information is often simultaneously processed on separate conscious and unconscious tracks
inattentional blindness
failure to notice/encode features when our attention is elsewhere
selective attention
focusing conscious awareness on a particular stimuli
blindsight
the ability of people who are cortically blind to respond to visual stimuli that they do not consciously see due to lesions in the primary visual cortex
sleep
a complex reversible neurobiological state characterized by closed eyes, behavioral quiescence, and perceptual disengagement from one’s surroundings
circadian rhythm
The natural cycle of physical, mental, and behavior changes that the body goes through in a 24-hour cycle.
electroencephalogram EGG
a test that measures electrical activity in the brain using small, metal discs (electrodes) attached to the scalp
sleep stages
Stage one, stage two, stage three, stage two, stage one REM.
beta waves
waking waves. these are tight lines
alpha waves
waking waves, but your brain is relaxed and typically preparing for sleep. these waves are spread apart but still tight
NREM 1 initial sleep stage
the brain waves look like beta but less tight. less brain activity. you can see random images as well.
NREM 2 stage 2
the waves start to go up, down, but are still a little tight and starting to go further apart. your body is in a deep state of relaxation.
NREM 3 stage 3
“slow waves” these waves are very far apart and very up and down. this stage is for memory consolidation. It’s hard to wake up.
REM emergent stage 1
these waves closely resemble alpha waking waves. this is the most important part of sleep. without it, people can’t seem to function well. we seem to have dreams during REM.
REM rebound
REM sleep is so important that if missed your brain will keep you in REM sleep longer the next time you sleep.
dreams
a state of consciousness characterized by sensory, cognitive and emotional occurrences during sleep
activation synthesis theory
when humans dream, the mind is trying to comprehend the brain activity that is taking place in the brain stem
information processing theory
sleep allows us to consolidate and process all of the information and memories that we have collected during the previous day
developmental psychology
a field of study that focuses on people’s change and growth across their lifespan
nature vs nurture
genes vs how one was raised
genes
The basic unit of heredity passed from parent to child
continuity vs stages
if someone’s personal evolutions happen in stages like pokémon or slowly evolve overtime
