![]() Consciousness is a complex, comprehensive brain function or a certain state of the mind of which we are aware; it enables activity inspired by knowledge and problem solving. On the other hand the unconsciousness includes mental processes that influence judgements, feelings, or behavior but are cut off from consciousness. Both states always work together. Yet the unconscious mind is the primary source of human behavior. Many of the major theories of psychology, ranging from the Freudian psychodynamic theories to contemporary work in cognitive psychology, argue that much of our behavior is determined by variables that we are not aware of. So how much of the time are we conscious when making decisions? Decisions in the brain are made gradually. But because the unconscious mind contains our biologically based instincts, much of the time we act without thinking consciously. The mind operates best by relaying a significant degree of high level, sophisticated processing to the unconscious. According to cognitive neuroscientists, we are conscious of only about 5 percent of our cognitive activity, so most of our decisions, actions, emotions, and behavior depends on the 95 percent of brain activity that goes beyond our conscious awareness. For example, the motor programs which tell the muscles what to do are all largely unconscious. These processes control which muscle fibers to contract for a certain amount of time. In addition, often times we are unaware of the exact words that will come out of our mouth as the brain chooses what to say when trying to get a point across. Similarly we are not always aware of how the vocal apparatus, which includes the voice box, lips, and tongue, produce the sounds that they produce. When speaking, we are unconscious of all the action that prompts the lips, jaw, and mouth to move the way that they do. This unconscious stimuli is what we call motor codes. Whether we like it or not, the unconscious mind takes control most of the time. But don’t worry, your brain knows what it's doing!
