Summary
Pathological lying, characterized by frequent, compulsive deception, is supported as a distinct diagnostic entity. Individuals identifying as pathological liars report increased distress and impaired functioning, warranting further clinical consideration.
Area of Science:
- Psychological Science
- Clinical Psychology
- Psychopathology
Background:
- Pathological lying, or pseudologia phantastica, has a history in literature but lacks formal diagnostic recognition.
- The field is moving towards empirically supported diagnoses, necessitating research into pathological lying's diagnostic validity.
Purpose of the Study:
- To empirically investigate if pathological lying aligns with nosological definitions.
- To determine if pathological lying can be established as a distinct diagnostic entity.
Main Methods:
- Recruited 807 participants from mental health forums, social media, and a university; 623 completed the study.
- Utilized lie frequency prompts, lying behavior questionnaires, the Lying in Everyday Situations Scale, and the Distress Questionnaire-5.
Main Results:
- 13% of participants identified as pathological liars (daily lies for >6 months).
- Pathological liars reported significantly greater distress, functional impairment, and perceived danger.
- Lying behavior appeared compulsive and often without clear external motivation.
Conclusions:
- Empirical evidence supports the establishment of pathological lying as a distinct diagnostic entity.
- Recommendations for defining pathological lying, exploring its etiology, and guiding future research and practice are presented.

01:18False Memories
135
False memories represent a cognitive distortion in which individuals recall events that did not happen, or remember them in an altered form. This phenomenon highlights the brain's constructive nature in processing and recalling memories, emphasizing that memory is not a perfect representation of past events but rather a dynamic reconstruction influenced by various factors.
One primary source of false memories is misattribution, where individuals incorrectly associate external information...

01:27Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
894
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...

01:29Theoretical Approaches to Psychological Disorder
280
The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...

01:26Positive Symptoms Schizophrenia: Hallucinations and Delusions
119
Schizophrenia is a complex psychiatric disorder characterized by a range of symptoms that significantly impact cognition, behavior, and emotional regulation. Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.

183
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...

Research is what makes the difference between facts and opinions. Facts are observable realities, and opinions are personal judgments, conclusions, or attitudes that may or may not be accurate. In the scientific community, facts can be established only using evidence collected through empirical research.
