This lesson explores dissociative disorders — conditions in which memory and identity become profoundly disrupted through psychological, not physical, causes. From dissociative amnesia and fugue states to depersonalization, derealization, and Dissociative Identity Disorder (DID), the section walks through each condition, the fierce scientific debates surrounding them, and what modern neuroscience is revealing. The discussion closes with a thought-provoking look at the non-pathological multiplicity spectrum and what it means for how we define a "normal" identity. In this video: • Dissociative disorders defined: a split from one's core sense of self with psychological — not physical — causes • Dissociative amnesia and fugue states: blocking out trauma, wandering, and temporarily adopting a new identity • The validity debate: 'psychiatric folklore' vs. clinical data showing ~10% of psychiatric outpatients meet criteria • Depersonalization (feeling robotic, detached from oneself) vs. derealization (surroundings feel foggy or artificial) • Dissociative Identity Disorder (DID): two or more distinct personality states, memory gaps, and its diagnostic history • The 1980s spike in DID diagnoses and the influence of the book and film Sybil on clinicians and the public • fMRI evidence showing objective brain-activity differences between DID patients and people faking the disorder, plus the emerging non-pathological multiplicity spectrum #OpenStax #Psychology #DissociativeDisorders #MentalHealth #DID OpenStax Content adapted from "OpenStax Psychology 2e", by OpenStax licensed under CC BY 4.0.
