Behaviors and characteristics that contributed to survival and reproduction persist --> traits become more common (i.e. sex differences in aggression) How do evolutionary psychologists explain ...

Relevant Background - Sleep is hard to study Dreaming is hard to study Psychological measures are required In 1955 - used EEG to measure brain activity and eye movement during sleep We go through several stages of sleep during the night Go in and out of REM and NREM sleep Vivid dreams are more likely to be remember during REM sleep EEG produces chart showing frequency and amplitude of activity changes over time The EEG can also be used to measure eye movement How many aims? -...

Stages of sleep : 1, 2, 3, 4 (all NREM) and REM Stage 1 sleep : light sleep, muscle activity slows down, occasional muscle twitching NREM Stage 2 sleep : Breathing pattern and heart rate slows, decrease in body temperature NREM Stage 3 sleep : Deep sleep begins, slow delta waves generated NREM Stage 4 sleep 2 | P a g e : very deep sleep, rhythmic breathing, limited muscle activity, brain produces delta waves REM sleep : Brainwaves speed up, dreaming occurs, muscles relax, heart rat...

Sensation correct answer: characteristics of incoming stimuli Perception correct answer: processes used to create a meaningful interpretation of sensations Transduction correct answer: external messages translated into language we can understand Light correct answer: transduced in vision; form of electromagnetic signals Anatomy of the Eye (Vision) correct answer: cornea and lens -> pupil -> retina -> receptor cells (rods and cones) -> optical nerve -> brain Dep...

What does EEG activity show? correct answer: the summed ionic flow (current) of thousands or even millions of neurons that have similar spatial orientation (if not similar spatial orientation, won't line up and waves not created) Do EEG recordings only reflect the electrical activity of neurons directly under the scalp electrodes are placed? correct answer: NO; because voltage decreases over distance, those deep in brain are less contributory BUT multiple areas are generally active during...
