Psychosurgery01:30

Psychosurgery

26
Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

Theoretical Approaches to Psychological Disorder

49
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...

Introduction to Personality Psychology

Personality encompasses a set of enduring traits and behavioral patterns that define how individuals think, feel, and interact, ultimately shaping their unique identities. The concept of personality has deep historical roots, deriving from the Latin term "persona," which means "mask." This term initially referred to the roles played by actors in ancient theater, signifying the different facets individuals display in various contexts.

Empathy

Some researchers suggest that altruism operates on empathy. Empathy is the capacity to understand another person’s perspective, to feel what he or she feels. An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor.

Self-Report Tests of Personality01:22

Self-Report Tests of Personality

272
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Area of Science:

  • Psychology
  • Forensic Psychology
  • Clinical Psychology

Background:

  • Psychopathy is a complex personality construct.
  • Previous research has utilized various methods to operationalize psychopathy.
  • A multi-method approach is crucial for a comprehensive understanding.

Purpose of the Study:

  • To examine the operationalization of psychopathy using a multi-method framework.
  • To identify underlying factors of psychopathy in a community sample.
  • To assess the construct validity of a proposed four-factor model of psychopathy.

Main Methods:

  • A community sample of 250 participants, oversampled for psychopathic traits.
  • Clinician-rated measures (Psychopathy Checklist: Screening Version, Comprehensive Assessment of Psychopathic Personality-Symptom Rating Scale).
  • Self-report measures (Triarchic Psychopathy Measure, CAPP-Self Report) and Exploratory Structural Equation Modeling.

Main Results:

  • A robust four-factor model of psychopathy emerged: Boldness, Disinhibition, Affective, and Interpersonal traits.
  • The model demonstrated general support for construct validity through associations with relevant scales.
  • The Interpersonal factor did not show incremental validity beyond Boldness and Affective factors.

Conclusions:

  • A four-factor structure provides a valid framework for understanding psychopathy.
  • Boldness and Affective traits are key components, with Disinhibition also significant.
  • The unique contribution of Interpersonal traits requires further investigation with broader criterion measures.
