Dark Triad and Person Perception

Dark Triad and Person Perception

Person perception is influenced by both external behaviors and the observer’s internal characteristics, including personality traits. Individuals with dark personality traits, comprising psychopathy, Machiavellianism, and narcissism — collectively known as the dark triad – exhibit manipulative and exploitative tendencies in social contexts. These traits affect how they perceive others and how they are perceived.The Role of Dark Personality Traits in Person PerceptionBlack et...

Personality Disorders: Paranoid and Schizoid

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.

Personality Theory by Eysenck and Eysenck

Personality Theory by Eysenck and Eysenck

Hans and Sybil Eysenck developed a widely recognized theory of personality, which emphasizes the role of temperament and genetically based differences in shaping individual traits. Their theory posits that biological factors primarily determine personality and can be understood through two main dimensions: extroversion/introversion and neuroticism/stability.
In the extroversion/introversion dimension, highly extroverted people are sociable, outgoing, and easily connect with others. In contrast,...

Personality Disorders: Narcissistic and Avoidant

Personality Disorders: Narcissistic and Avoidant

Narcissistic and avoidant personality traits represent two contrasting patterns of behavior that significantly influence social interactions and self-perception. While individuals with narcissistic disorder seek admiration and validation, individuals with avoidant personality disorder withdraw due to fear of judgment.
Characteristics of Narcissistic Personality Disorder
Narcissistic individuals exhibit an inflated sense of self-importance and an excessive need for admiration. They are often...

Traits and States

Traits and States

Personality traits represent consistent patterns in behavior, thoughts, and emotions, reflecting an individual's tendencies across various situations. For example, extraversion, a well-known trait, manifests in individuals as talkative, energetic, and enthusiastic behaviors. These traits are stable over time, offering a reliable framework for predicting how people might act in different contexts. However, they do not define every moment of an individual's life. In contrast to traits,...

Psychodynamic Perspectives on Personality

Psychodynamic Perspectives on Personality

The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.
Psychodynamic theorists argue that unconscious...

Area of Science:

Psychology
Sleep Science
Behavioral Genetics

Background:

Sleep is crucial for overall health.
The relationship between maladaptive personality traits and sleep remains under-explored.
Existing research primarily focuses on adaptive traits and their sleep impact.

Purpose of the Study:

To investigate the genetic and environmental links between sleep and four maladaptive personality domains (Negative Affectivity, Detachment, Disinhibition, Psychoticism).
To analyze these associations within the DSM-5 Alternative Model of Personality Disorders (AMPD) framework.
To determine the extent to which genetic factors influence the relationship between maladaptive traits and sleep.

Main Methods:

Utilized a twin study approach to estimate phenotypic, genetic, and environmental variance and covariance.
Employed multilevel regression analysis with a co-twin control design.
Assessed associations between four maladaptive domains and sleep duration, efficiency, and quality.

Main Results:

Phenotypic and genetic correlations revealed significant associations between maladaptive domains and sleep parameters, particularly sleep quality.
Negative Affectivity and Detachment showed the strongest correlations with sleep.
Genetic factors partially explained the observed relationships, indicating a role for environmental influences as well.

Conclusions:

Maladaptive personality traits are significant predictors of sleep health.
Both genetic and environmental factors contribute to the interplay between personality and sleep.
Future research should consider maladaptive traits when examining sleep disturbances.
