PSYC 140 MODULE 3 EXAM 2026 FINAL
REVIEW EXAM
◉ Levels of Consciousness. Answer: 1. Normal Waking
2. Altered State (meditating, sleep, daydreaming)
◉ Cognitive Neuroscience. Answer: the interdisciplinary study of the
brain activity linked with cognition (including perception, thinking,
memory, and language)
◉ 23 year old woman study. Answer: -had accident resulting in no
outward signs of consciousness
-When asked to imagine playing tennis, fMRI showed brain activity
in areas that control arms and legs
◉ Even in a motionless body, the brain is still ________.. Answer: active
◉ Cocktail Party Effect. Answer: phenomenon of the brain's ability
to focus one's auditory attention on a particular stimulus while
filtering out a range of other stimuli
◉ Selective Attention. Answer: -focusing conscious awareness on a
particular stimulus
,-"flashlight" effect
ex. turning down the music to park lol me
◉ Inattentional Blindness. Answer: -failure to see objects when
attention is directed elsewhere
ex. not seeing the gorilla in that video
◉ change blindness. Answer: -failure to notice changes in the
environment
ex. not noticing line on road goes from dotted to solid
◉ sleep. Answer: periodic, natural loss of consciousness
◉ biological rhythms. Answer: -24 hour biological clock
-90 min sleep cycle for younger adults

cycle of day and night
◉ Body temperature. Answer: -rises as morning approaches
-peaks during the day
-dips in the early afternoon
, -begins to drop in evening
◉ suprachiasmatic nucleus (SCN). Answer: -structure that
"contains" 24 hour clock
-lesions to SCN = no circadian rhythm
◉ Babies sleep rhythm. Answer: -have no SCN
-takes around 3 months to develop
-"sleep trained"
◉ Sleep researchers measure. Answer: 1. brain-wave activity
2. eye movements
3. muscle tension
◉ Electroencephaiography (EEG). Answer: records electrical activity
in brain
◉ Electro-oculography (EOG). Answer: records eye movements
◉ Electromyography (EMG). Answer: records muscle activity
◉ Brain Waves. Answer:
