Chapter 4: Consciousness: The subjective experience of the world and of mental activity. It refers to moment-by-moment subjective experiences, such as reflecting on one’s current thoughts or paying attention to one’s immediate surroundings. Two contents of consciousness: Contents of consciousness (the things we are conscious of) Level of consciousness (such as coma, sleep, and wakefulness) Things are done consciously and unconsciously . Natural Variation = Sleep, Natural Manipulation = Meditation, & Artificial Manipulation = Drugs. Split Brain: A condition in which the corpus callosum* is surgically cut and the two hemispheres of the brain do not receive information directly from each other. *Corpus Callosum: The major connection between the hemispheres that may readily be cut without damaging the gray matter. The right side of the body is usually connected to the left hemisphere of the brain and the left side of the body is usually connected to the right hemisphere of the brain. (E.g. An image on our right goes to the left hemisphere of the brain and an image on our left goes to the right hemisphere of the brain) Interpreter: A left hemisphere process that attempts to make sense of events. It is the left hemisphere’s propensity to construct a world that makes sense. If a person has a split brain, the two halves of the hemisphere can communicate through an outside medium (e.g. paper if the person is drawing) and not within the person’s head. The left brain interpreter seems to compress its experiences into a comprehensible story and to reconstruct remembered details based on the gist of that story. Sometimes the left brain interpreter makes life more difficult than it needs to be. Leads people to search for patterns that might not even exist. The right brain interpreter seems simply to experience the worlds and remember things in a less distorted by narrative interpretation. Subliminal Perception: Information processed without conscious awareness. We are not very good at describing perceptual experiences; when we are forced to do so, the act of verbally labeling alters our memories. Although it is unclear exactly why thinking too much can impair judgment and memory, some things appear to be best left unsaid.

Prefrontal Cortex = “I understand plans.” Frontal Motor Cortex = “I’m all about movement.” Parietal Lobe = “I’m aware of space” Temporal Lobe = “I see and hear things” Occipital Lobe = “I see things” REM (Rapid Eye Movements) sleep: The stage of sleep marked by rapid movements, dreaming, and paralysis of motor systems.
