Dissociative Disorders01:27

Dissociative Disorders

1.1K
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.

Dissociative Identity Disorder

2.4K
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...

Dissociative Amnesia01:21

Dissociative Amnesia

1.2K
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...

Deindividuation00:57

Deindividuation

22.4K
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.

Subconsciousness and No Awareness01:15

Subconsciousness and No Awareness

864
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...

High-Level and Low-Level Awareness01:19

High-Level and Low-Level Awareness

989
Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

Area of Science:

  • Psychology
  • Sleep Science
  • Trauma Studies

Background:

  • Dissociative symptoms are sometimes linked to irregular sleep-wake cycles.
  • Dissociation shares overlaps with fantasy proneness and cognitive failures, suggesting potential underlying mechanisms.

Purpose of the Study:

  • To test two conceptual models explaining the relationship between unusual sleep experiences, fantasy proneness, cognitive failures, and trait dissociation.
  • To investigate the role of trauma in dissociative experiences and its connection to sleep.

Main Methods:

  • Path analysis was used to examine data from a nonclinical sample (N=139) predominantly composed of females.
  • A cross-sectional design was employed to evaluate the proposed conceptual models.

Main Results:

  • Both tested models provided a reasonable fit to the data.
  • Unusual sleep experiences were identified as significant antecedents of trait dissociation in both models.
  • The findings suggest a link between sleep disturbances and dissociative tendencies.

Conclusions:

  • Unusual sleep experiences play a crucial role in the development of trait dissociation.
  • Interventions focused on sleep normalization may be beneficial for individuals experiencing dissociative symptoms.
  • Further research into the sleep-dissociation link is warranted.
