Document Summary
John watson: consciousness: not observable, not scientific. Sensory neglect (hemispatial neglect)-damage to right parietal lobe, not aware of left side of their body or vision. Simultanangnosia- they cannot attend to two objects at once. If they focus on one thing, they are not aware of any other objects: sleep behavior: type of unconsciousness. Measures the net sum of electrical activity over the entire cerebral cortex. From this, you get electrical activity that shoes sleep stages. When people are awake, brain waves and choppy quick, low voltage waves. In your deepest sleep, the amplitude is great and the waves are slow. As you fall into deeper and deeper sleep, more neurons fire in unison so more of the positives are adding together, so the amplitude gets greater. Synchronicity- neurons fire together so amplitudes add together. Rem sleep-rapid eye movement, also called paradoxical sleep. Percentage of rem sleep is greatest in species that sleep a lot.
