Long-term Depression01:05

Long-term Depression

27.3K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Fundamental Attribution Error

12.8K
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

Avoidance Learning and Learned Helplessness

4.2K
Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...

Need for Self-Esteem01:27

Need for Self-Esteem

305
The human need for self-esteem has long intrigued psychologists, leading to the development of several theories that explore its evolutionary and functional significance. Among the most influential are the sociometer, hierometer, and terror management theories. Each offers a unique perspective on why people strive for self-worth and how it shapes behavior and social interaction.Sociometer TheoryAccording to sociometer theory, self-esteem functions as an internal gauge of social acceptance. It...

Self-Serving Bias01:29

Self-Serving Bias

374
Self-serving bias is a cognitive phenomenon in which individuals attribute positive outcomes to internal factors such as their abilities, intelligence, or effort while attributing negative outcomes to external circumstances. This cognitive distortion helps maintain self-esteem but can also impede objective self-assessment.Theoretical Explanations of Self-Serving BiasTwo primary theories explain the self-serving bias: the cognitive explanation and the motivational explanation.The cognitive...

Summary

This study differentiates post-aggression suicide from extended suicide. Understanding this distinction is crucial for accurate forensic psychiatric evaluations in legal cases involving violence and suicide.

Area of Science:

  • Forensic Psychiatry
  • Psychology
  • Criminology

Background:

  • Differential diagnosis of suicides following homicide is complex.
  • Existing definitions of post-aggression and extended suicide lack clear differentiation.
  • Forensic psychiatric assessments require precise categorization of such cases.

Purpose of the Study:

  • To clarify the diagnostic criteria distinguishing post-aggression suicide from extended suicide.
  • To provide a framework for forensic psychiatric evaluations in homicide-suicide cases.
  • To enhance the accuracy of legal and law enforcement assessments.

Main Methods:

  • Review of existing literature on homicide-suicide.
  • Analysis of case characteristics differentiating perpetrator motivations.
Keywords:
altruistic motivationextended suicideforensic psychiatric opinion

  • Comparative analysis of defining features of post-aggression and extended suicide.

    • Main Results:

    • Post-aggression suicide is characterized by perpetrator's long-standing violence, jealousy, revenge, hatred, or desire to inflict severe harm.
    • Extended suicide is defined by altruistic motives, severe mental disturbances, and transference of problems onto family.
    • Key differentiating factors include perpetrator's motivation and the nature of violence.

    Conclusions:

    • Accurate differentiation between post-aggression and extended suicide is vital for forensic psychiatric opinions.
    • This distinction impacts legal and law enforcement understanding of complex criminal cases.
    • Clearer diagnostic criteria improve the reliability of forensic assessments in homicide-suicide incidents.
