Consciousness: awareness of self and environment, look at chart of the altered states of consciousness. History of consciousness: 1880-defined as description and explanation of consciousness, first half of 20th century-direct observation of behavior, 1960"s-conciousness nearly lost; science of behavior, after 1960"s- Cognitive neuroscience: interdisciplinary study of the brain activity linked with cognition (including perception, thinking, memory, and language) Owen: observed people imagining playing tennis to test memory, hippocampus-memory, showed brain activity and consciousness, watched video of guy asking other guy if he was in pain. Dual processing: the two-track mind, information is often simultaneously processed on separate conscious (explicit-trying to solve a problem) and unconscious (implicit-automatic functions like walking, we aren"t necessarily aware of it, another example is anxiety) tracks. Perceptions, memory, attitudes, and other cognitions are affected. Selective attention: focusing conscious awareness on a particular stimulus, ex: cocktail party- loud environment and we are able to focus on the person we are talking to.
