4. Consciousness Waking consciousness Altered States of Consciousness
Our awareness of ourselves and our environment
Thoughts, feelings, and perceptions that occur when we are awake and alert
Allows us to reflect and plan
Altered States of Consciousness
A mental state that differs noticeably from normal waking consciousness

5. Subconscious Processing
Well-learned tasks become automatic
Driving
Typing
When you meet people you unconsciously react to their gender, age and appearance
Subconscious processing
Bird (color, form, movement, distance)
Unconscious processing is parallel while conscious is linear but good at novel problems

6. Forms of Altered-Consciousness
Sleep

7. History of Consciousness
Psychology began as a science of consciousness. (Titchner and Structuralism)
Behaviorists argued about alienating consciousness from psychology.
However, after 1960, mental concepts (consciousness) started reentering psychology.
OBJECTIVE 1| Discuss the history of psychology’s study of consciousness and contrast conscious and unconscious information processing.

8. What is waking consciousness?
Picture this: It is a beautiful spring day and you are walking down a country lane, absorbed in thought. Birds are chirping, roses are in bloom and the sun feels warm on your face. Suddenly, you hear a dog bark and you switch your attention to seeing if the animal means to bite.
Adapted from How the Brain Might Work: A New Theory of Consciousness By SANDRA BLAKESLEE

9. What is waking consciousness?
How do you – (how does the brain)- bind these fragmented sensory signals and perceptions into a single coherent image? I am at the park about to get eaten by my uncle’s childhood dog.

10. Evolutionary Reason for Consciousness
Consciousness as an adaptation allowing us to get along with others in our group (humans)
Allows us to ‘see’ ourselves and therefore moderate our behavior.

11. Tripartite Theory - Freud

12. The Stream of Consciousness
Consciousness results from the activity of the thalamus which analyzes and interprets information in the cerebral cortex.
“sweeping or scanning” total a rate of 40 times per second
Each sweep results in a single image or “moment of consciousness”
Intralaminar nucleus, a kind of doughnut of cells within the thalamus, has nerve cells that send out long axons that reach to every part of the cerebral cortex. Significantly, there are also returning axons that come down from all areas of the cortex back to the intralaminar nucleus.

13. Consciousness: A Chord of Subconscious Brain Events
Neuroscientists believe that consciousness emerges from the interaction of individual subconscious brain events much like a chord that is created from different musical notes.
Move wrist seconds prior to moving your wrist, you must decide to move the wrist since it takes that long to travel to the wrist.
But it isn’t until 0.35 seconds after that your brain waves jump
If told to hit a button after a tone you can respond in 1/10th of a second, but won’t show the jump in brain waves until .35 seconds.
You live in the past – but only by a bit

14. Daydreaming and Fantasy
Spontaneous shifts attention away from the here and now into a make-believe world
Urge to daydream peaks about every 90 minutes and is highest between 12:00 and 2:00pm
Daydreams may provide stress relief and encourage creativity
