Bonanno's Theory of Grieving01:17

Bonanno's Theory of Grieving

1.5K
Grieving is a complex psychological and emotional process that varies significantly among individuals. George Bonanno's research on bereavement identified four distinct patterns of grieving, offering a nuanced understanding of how people cope with significant loss, such as the death of a spouse, over extended periods. These patterns — resilience, recovery, chronic dysfunction, and delayed grief — highlight the diversity in emotional responses and adaptive mechanisms.

Evolutionary Psychology

1.3K
Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the...

Kubler Ross's Stages of Dying

2.1K
Elisabeth Kübler-Ross significantly advanced psychology's understanding of the process of dying with her influential book, On Death and Dying (1969). She focused on studying terminally ill individuals and outlined five stages commonly experienced when coping with death: denial, anger, bargaining, depression, and acceptance.
In denial, individuals reject the reality of their condition, often thinking, "This isn't true; I feel fine," as a way to protect themselves from...

Evolution of New Traits in Microbes

199
Microorganisms evolve rapidly due to their large population sizes and short generation times, often exhibiting measurable changes within days under laboratory conditions. Natural selection acts on standing genetic variation, enabling the retention and amplification of beneficial traits that confer fitness advantages in changing environments.Adaptive Pigment Regulation in RhodobacterIn Rhodobacter, a genus of purple non-sulfur bacteria, light-harvesting pigments such as bacteriochlorophyll and...

What is Evolutionary History?

31.1K
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

Ending Relationships01:28

Ending Relationships

256
The dissolution of intimate relationships presents complex emotional and psychological challenges, particularly when emotional bonds are strong, the relationship is long-standing, and perceived alternatives are limited. This distress often intensifies in romantic breakups, where the initiator may experience greater turmoil than the rejected partner. Contributing factors include residual attachment, guilt over causing pain, and uncertainty about how to manage the situation. The stress is further...

    Summary
    This summary is machine-generated.

    Pathological grief, or complicated grief, remains controversial. While intense, prolonged grief can be disabling, it is not yet a distinct mental disorder in major classifications like ICD-10 and DSM-IV-TR.

    Area of Science:

    • Psychiatry
    • Psychology
    • Mental Health

    Context:

    • Bereavement is a universal human experience.
    • The association between bereavement and increased morbidity/mortality is established.
    • Current international classifications (ICD-10, DSM-IV-TR) do not recognize complicated grief as a distinct mental disorder.

    Purpose:

    • To explore the controversial concept of pathological grief.
    • To review the evolution of criteria for persistent complex bereavement disorder.
    • To present a case report illustrating clinical challenges.

    Summary:

    • Complicated grief, characterized by prolonged, intense, and disabling grief, is debated as a distinct mental disorder.
    • The Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) included proposed criteria for persistent complex bereavement disorder in its "conditions for further study" section.
    • A case report from a Geneva crisis center details the treatment of a woman experiencing complicated grief after her husband's sudden death.

    Impact:

    • Highlights the ongoing debate and diagnostic challenges surrounding pathological grief.
    • Informs clinicians about the evolving understanding and potential future classification of complicated grief.
    • Provides a clinical example for understanding and managing severe bereavement reactions.
