Personality Disorders: Paranoid and Schizoid01:22

Personality Disorders: Paranoid and Schizoid

Personality disorders represent enduring cognition, affect, and behavior patterns that significantly deviate from societal norms. These maladaptive traits often lead to difficulties in various domains, including interpersonal relationships, occupational settings, and overall psychological well-being. Paranoid personality disorder and schizoid personality disorder are two distinct conditions marked by odd or eccentric behavior.

Negative and Cognitive Symptoms of Schizophrenia01:30

Negative and Cognitive Symptoms of Schizophrenia

Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Positive Symptoms of Schizophrenia: Hallucinations and Delusions

Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.
Thought Disorders
Disorganized and unusual thought processes mark thought disorders in schizophrenia. One key feature is disorganized speech, where an individual's conversation includes loosely...
Schizophrenia01:17

Schizophrenia

Schizophrenia, a term introduced by Swiss psychiatrist Eugen Bleuler in 1911, describes a severe psychological disorder marked by profound disruptions in attention, thought processes, language, emotion, and interpersonal relationships. The core feature of schizophrenia is psychosis — a state characterized by a fundamental detachment from reality. This disconnection manifests through distorted logic, impaired perception, and atypical behavior, severely affecting the lives of those diagnosed.
Psychosexual Stages of Personality: Latency01:16

Psychosexual Stages of Personality: Latency

Following the phallic stage in Freud's theory of psychosexual development, children enter a phase called the latency period, which lasts from approximately six to twelve years of age. Unlike earlier stages, where sexual impulses played a central role, Freud believed these impulses are repressed during the latency period, becoming part of the unconscious. This stage is often described as a time of psychological calm after the turbulence of the phallic stage.
The latency period is not considered...
Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders01:27

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within the...

Area of Science:

  • Neuroscience
  • Psychiatry
  • Phenomenology

Background:

  • Temporal orientation is crucial for understanding voluntary action and selfhood.
  • Schizophrenia presents with passivity experiences, suggesting disruptions in agency and temporal awareness.
  • Existing neuroscience methods often overlook the 'immediate present' due to recording constraints.

Observation:

  • The immediate present is defined as the time before action confirmation.
  • The non-immediate present follows action confirmation.
  • Neuroscience findings show cerebral initiation precedes conscious intention for voluntary acts.

Findings:

  • Schizophrenic passivity mirrors the temporal lag observed in voluntary actions, with awareness of alien control occurring after external causation.
  • This suggests schizophrenic passivity is a disturbance in anchoring to the immediate present.
  • The self's relationship to the immediate present is elucidated through an anthropological concept of 'life'.

Implications:

  • Understanding the immediate present is key to comprehending agency and self-awareness in schizophrenia.
  • This research offers a novel phenomenological framework for studying passivity experiences.
  • Findings may inform therapeutic interventions targeting temporal disorientation in psychiatric disorders.
