Psychodynamic theorists argue that unconscious...

    Summary

    Psychogenic trance, once viewed as conversion hysteria, is now classified under dissociative disorders. This condition involves impaired psychic integration, affecting memory, identity, and sensory functions.

    Area of Science:

    • Psychiatry
    • Psychology
    • Neuroscience

    Context:

    • Historically, psychogenic trance was misclassified as 'conversion hysteria'.
    • Current understanding places psychogenic trance within the spectrum of dissociative disorders.
    • Dissociative disorders are characterized by disruptions in the integrative functions of the psyche.

    Purpose:

    • To re-evaluate the classification and understanding of psychogenic trance.
    • To differentiate psychogenic trance from other dissociative disorders.
    • To outline the common characteristics and subtypes of dissociative disorders.

    Summary:

    • Psychogenic trance involves a temporary loss of habitual identity while maintaining some awareness of surroundings.
    • Dissociative disorders feature impaired control over memory, identity, sensory, and motor functions.
