Contemporary concepts of dissociation

Area of Science:

• Psychology
• Neuroscience

Background:

• Dissociation was conceptualized by Pierre Janet in the late 19th century to explain phenomena like "double consciousness."
• Janet defined dissociation as a failure in integrating personality systems, linking it to genetics, illness, fatigue, and trauma.

Observation:

• By the late 20th century, dissociation concepts became varied and contradictory.
• Current understanding defines dissociation as a separation of behavior, thoughts, and emotions, encompassing normal and abnormal states.

Findings:

• The complete mechanisms underlying dissociation remain largely unknown.
• Research primarily investigates dissociation through studies on hypnosis and post-traumatic stress disorder (PTSD).

Implications:

• The ongoing controversies in defining dissociation suggest a need to revisit Janet's original conceptualization.
• Revisiting historical definitions may provide a foundational premise for future research and theoretical development in dissociation.
