Dissociative Disorders

Dissociative Disorders

Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.

Altered States of Awareness

Altered States of Awareness

Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.
The ingestion of substances like stimulants or hallucinogens leads to chemical alterations in the brain that...

Dissociative Amnesia

Dissociative Amnesia

Dissociative amnesia is a complex psychological condition that manifests as an inability to recall personal information, often tied to traumatic or stressful events. Unlike general amnesia, individuals with this condition retain the ability to perform routine activities and procedural tasks, such as operating a phone or navigating public transportation, yet experience profound gaps in autobiographical memory. These lapses may encompass significant life events, such as suicide attempts or...

Dissociative Identity Disorder

Dissociative Identity Disorder

Dissociative Identity Disorder (DID), previously termed multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states. Each identity exhibits unique patterns of behavior, voice, and mannerisms and may possess separate memories and emotional responses. The alternating control between identities can result in memory gaps and challenges in recalling daily activities, often exacerbating the individual's...

Subconsciousness and No Awareness

Subconsciousness and No Awareness

The concept of subconscious awareness refers to the processing of information below the level of conscious thought, which significantly influences both behaviors and decisions. It is also known as waking subconscious awareness. This complex level of cognition operates without the direct awareness of the individual, facilitating rapid and simultaneous handling of multiple information streams.
An illustrative example of subconscious processing is its role in problem-solving. Often, individuals...

Deindividuation

Deindividuation

Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

Area of Science:

Psychology
Neuroscience

Background:

Clark Hull's (1933) influential research on dissociation was based on a flawed premise, ignoring the established concept of dissociation as automatism.
This oversight led to a 60-year dominance of Hull's inaccurate view within the hypnosis field, overshadowing the phenomenon of dissociation.

Discussion:

This essay reintroduces the Janetian paradigm of dissociation as automatism, defining automatisms as involuntary behaviors that occur spontaneously.
It posits that the human experience of involuntariness is evolutionarily significant and fundamental to both hypnotic responses and dissociative symptoms.

Key Insights:

Hull's critique of dissociation was based on a misrepresentation, failing to acknowledge dissociation as automatism.
The experience of involuntariness is a crucial, evolutionarily selected trait central to hypnosis and dissociation.

Outlook:

The hypnosis and dissociation fields should collaborate on investigating the experience of involuntariness.
Recent neuroimaging suggests the parietal cortex plays a key role in the experience of involuntariness, warranting further study.
