Document Summary

Consciousness- our awareness of ourselves and our environment. Cognitive neuroscience: the interdisciplinary study of the brain activity linked with cognition (including perception, thinking, memory, language) Sensation: the brain receives input from the sensory organs. Perception: the brain makes sense out of the input from sensory organs. Dual processing: the principle that information is often simultaneously processed on separate conscious and unconscious tracks. Bottom-up processing: taking sensory information and then assembling and integrating it (what we are seeing) How we sense the world is the base of how we can connect to the outside world whether it is physical or social. Top-down processing: using models, ideas, and expectations to interpret sensory information. (is that something you have seen before?) Absolute threshold: the minimum level of stimulus intensity needed to detect a stimulus half the time. Subliminal: below our threshold for being able to consciously detect a stimulus, but still registered by the sensory organ.
