Attachment01:20

Attachment

533
Attachment is vital for infant development, as warm social interactions support growth and well-being. In a classic 1958 study by Harry Harlow, the significance of warmth and comfort in forming attachments was examined. Harlow separated newborn monkeys from their mothers and provided two artificial "mothers": one made of cold wire and the other covered in soft cloth. Despite the wire mother offering food, the infant monkeys preferred the comfort of the cloth mother, demonstrating that...

Attachment is a long-standing connection or bond with others. While Attachment Theory was conceived in developmental psychology to describe infant-caregiver bonding, it's been extended into adulthood to include romantic relationships.

Attachment Styles01:24

Attachment Styles

452
Jeffrey Simpson's attachment theory suggests that early caregiver relationships shape lasting patterns of behavior and emotional regulation, known as attachment styles. These patterns are organized along two key dimensions: self-esteem and interpersonal trust. The intersection of these dimensions produces four primary attachment styles that typically persist throughout life and significantly influence how individuals form and maintain relationships.Secure Attachment StyleIndividuals with a...

Attachment of Sister Chromatids02:57

Attachment of Sister Chromatids

4.1K
As cells progress into mitosis, the nuclear envelope breaks down, and the condensed chromosomes are exposed to the array of bipolar microtubules of the mitotic spindle. The kinetochore, a large, disc-shaped protein complex, is present at the centromere region of the sister chromatids and acts as a binding site for the microtubules.  Usually, the plus-end of a single microtubule is embedded within the kinetochore. However, some kinetochores first establish lateral contact with the side-wall...

Drug Classes and Categories01:25

Drug Classes and Categories

3.1K
Drugs can be classified according to their chemical composition or their intended therapeutic application. For instance, anti-infective agents that possess the ability to eliminate pathogens or suppress their growth and reproduction can be grouped based on the organisms they target or their chemical structure. Furthermore, drugs can be divided into prescription, nonprescription, or controlled substances. Prescription medications, such as antibiotics, require oversight from a licensed healthcare...

Antibody Structure and Classes01:25

Antibody Structure and Classes

9.2K
Antibodies, also known as immunoglobulins, are produced by B cells in response to foreign substances, such as bacteria and viruses. These proteins are critical for recognizing and neutralizing these substances, protecting the body from potential harm.
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.

Area of Science:

  • Psychology
  • Mental Health
  • Attachment Theory

Background:

  • Bereavement significantly impacts mental health.
  • Attachment theory offers a framework for understanding grief.
  • The link between attachment styles and bereavement responses requires further investigation.

Purpose of the Study:

  • To identify subgroups of bereaved individuals based on prolonged grief and depression symptom patterns.
  • To examine the relationship between these subgroups and attachment anxiety and avoidance.

Main Methods:

  • Latent Class Analysis was employed.
  • 285 bereaved individuals were analyzed.
  • Attachment anxiety and avoidance were assessed.

Main Results:

  • Three distinct subgroups emerged: Prolonged Grief Disorder/Depression (PGD/Depression), Depression, and Low symptoms.
  • Attachment anxiety significantly predicted group membership.
  • Attachment avoidance correlated with increased depressive symptoms.

Conclusions:

  • Insecure attachment styles are relevant to understanding prolonged grief disorder.
  • Attachment anxiety is a key predictor for individuals experiencing PGD and depression.
  • Attachment avoidance is associated with higher levels of depressive symptoms in bereavement.
