Tuesday Night Lecture – I was going to record the lecture but turns out I have no voice left with this cold.  Therefore, I will ask that you write down the following points on your ppt notes that are attached to the sleep lab!  Also, watch Crash Course on Altered States.

NOTES:

Why do we dream?

1.  Freud’s Theory- (wish fulfillment) dreams are time for the id to express itself; they reflect our innermost desires that are too threatening to express directly.  Thus, dreams have manifest content (the literal narrative) and latent content (the underlying meaning)
2.  Information processing – dreams facilitate memory by rehearsing important events; dreams are bizarre because we incorporate other memories into them.
3.  Activation-Synthesis theory – the brain periodic “exercises” during the night by sending random electrical impulses; dreams are the brain’s interpretation of its own activity

Hypnosis

1.  an interaction in which on person suggests to another that certain perceptions, feelings, etc will occur spontaneously.
2. Theories of Hypnosis
   1. Social Influence Theory:  Hypnosis an extension of everyday social behavior
   2. Divided consciousness Theory:  hypnosis is a dissociation between our conscious awareness and our automatic behaviors.
