States of Consciousness 13/11/2007 04:26:00 I. What is consciousness? Working definition: our moment-to-moment awareness of  ourselves and of our environment. Alternate definition: our awareness of the  sensations, thoughts, and feelings that we are attending to at any given moment. A. Basic Characteristics Subjective/Private Dynamic (not static). Changes over time, even rapidly Self-reflective (self-aware) Central to our sense of “self” or sense of “identity” Closely related to the process of selective attention  (the process that focuses  awareness on some stimuli to the exclusion of other stimuli) II. Freudian vs. Cognitive Perspectives A. Freud’s Model Conscious mind = thoughts/perceptions of which we are currently aware Preconscious mind = mental events. Outside current awareness but which  can be brought to awareness easily Unconscious Mind = mental events/instinctual urges that cannot easily be  brought to conscious awareness B. Cognitive Perspective Controlled processing (effortful) = the conscious use of attention and effort (to  process information) Automatic processing (unconscious/non-conscious) = activities that are  performed without conscious awareness + effort o Divided attention = capacity to perform more than one activity at a time III. Dissociations of Consciousness A. Dissociative Identity Disorder (D.I.D.) A. Dissociative Disorders: A portion of one’s life become dissociated from one’s  normal identity, consciousness, and/or memory B. D.I.D.: The existence within the individual of 2 or more identities, each of  which is dominant at a particular time

Onset: usually in childhood, but may not be diagnosed until adolescence G. Why does it develop: Trauma-dissociation theory o Sample of DID patients (100 people) o 87-97% of these patient were exposed to severe, prolonged abuse  during childhood I.  Sleep A. Stages of Sleep H. Stage 1: Light Sleep I. 1-2% of sleep time spent in stage 1 J. Brainwaves begin to slow down (theta waves 4-7 cycles per second vs. 14  c.p.s. alpha waves when awake) K. Easy to awaken L. Vivid images are possible M. No subjective feeling of having been asleep N. Stage 2 O. 40-60% of nightly sleep time spent in stage 2 P.
