Consciousness What does it mean to have free will? -that we are consciously controlling our lives. What is Consciousness? What is your state of awareness? – Drowsy, attentive, day dreaming… What is your self-aware content? Sights, sounds, what do you feel (touch) Consciousness comes from the Latin meaning to know. Can refer to your current awareness of surroundings The mind, held by the brain, holds our consciousness. The dimensions of Consciousness There are two dimensions of consciousness: wakefulness and awareness - Wakefulness id how alert you are in conjunction with how awake you are. - Awareness is the how well you are comprhendng or monitoring the information around you - EX: You can be awake but not aware (for example a drunk person is defiantly awake but not very aware of what he or she is doing) The threaded cognitive theory - posits that streams of thought can be represented as threads of processing coordinated by a procedural resource, without the need for task-specific executive processes.
