42
Dissociative disorder
What is happening here?
Hypnosis and the study of “dual consciousness”
“Pre-attentive Processing”
1. “Dry”: the research in the lab
... the how of “implicit perception and memory”
2. “Wet”: the experience of everyday life
... the why of “intentional not-thinking”
43
Dissociative disorder
Autobiographies: “deep” and “superficial” memories
... the facts, feelings and fictions
Demonstrations of dissociation: group & personal ones
... the Dissociative Experiences Scale
44
Dissociative disorder
1. Dissociative Amnesia
 Motivated lack of awareness
 Recovered Memories
1. “Dry”: the learning theory view of memory
... how learning and memory serve external, adaptive needs
2. “Wet”: the psychodynamic view of memory
.
.. how learning and memory serve internal, personal needs
The lesson from life:
“the complexity of awareness about highly traumatic events”
45
Dissociative disorder
2. Dissociative Fugue
 Motivated lack of awareness and movement
 Episodic, declarative and procedural memory
46
Dissociative disorder
3. Dissociative Identity Disorder

 Sociocognitive view

4. Depersonalization Disorder
