Psychosurgery01:30

Psychosurgery

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 Disorder01:29

Theoretical Approaches to Psychological Disorder

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...
Archival Research01:40

Archival Research

Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...
Humanistic Psychology01:24

Humanistic Psychology

Humanistic psychology emerged in the mid-20th century as a response to the deterministic and pessimistic nature of behaviorism and psychoanalysis. While behaviorism focused on observable behaviors influenced by the environment and psychoanalysis delved into unconscious motivations, both theories suggested that human actions lacked free will. In contrast, humanistic psychology offers a perspective that emphasizes the innate potential for goodness and growth within every individual.
This approach...
Contemporary Psychology01:29

Contemporary Psychology

Psychology explores human behavior and mental processes through various lenses, each offering unique insights. This overview examines key subfields, including biopsychology, evolutionary, developmental, personality, and social psychology, highlighting their approaches and contributions to understanding complex human behaviors.
Biopsychology
Biopsychology, also known as biological psychology or behavioral neuroscience, focuses on the biological underpinnings of behavior and mental processes. It...
Ethics in Research01:56

Ethics in Research

Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.

Area of Science:

  • Psychology
  • Psychiatry
  • Forensic Science

Background:

  • The psychological autopsy (PA) method is frequently used in suicide research.
  • Concerns exist regarding the methodological rigor of existing PA studies.

Purpose of the Study:

  • To review research utilizing the PA method in suicide studies.
  • To identify and discuss methodological problems within PA research.
  • To suggest future research directions and improvements.

Main Methods:

  • Literature review of studies employing the psychological autopsy method for suicide research.
  • Analysis of reported methodological shortcomings, including sampling, variable control, and assessment reliability.

Main Results:

  • Identified significant methodological problems in PA research.
  • Highlighted issues such as sampling biases in control subjects, confounding variables, and unreliable assessment instruments.
  • Noted a lack of procedural homogeneity and defined guidelines across studies.

Conclusions:

  • The validity and reliability of PA findings are compromised by current methodological inconsistencies.
  • Standardization of the psychological autopsy method is essential for improving the quality of suicide research.
  • Further empirical investigation is needed to address identified research questions.
