These factors interact to create a threshold for the development of mental disorders. The types of coping and defense mechanisms used can either contribute to vulnerability or act as protective factors. [39] Coping and defence mechanisms work in tandem to balance out feelings of anxiety or guilt, categorizing them both as a "mechanisms of ...
Phebe K. Cramer (December 30, 1935 – April 2, 2021) was an American clinical psychologist who was Professor of Psychology, Emerita at Williams College. [1] She was known for her research on defense mechanisms, body image, and narcissism, and for her creation of a manual for coding defense mechanisms for purposes of psychological testing and personality assessment.
Chemical defense is a strategy employed by many organisms to avoid consumption by producing toxic or repellent metabolites or chemical warnings which incite defensive behavioral changes. [ 1 ] [ 2 ] The production of defensive chemicals occurs in plants, fungi, and bacteria, as well as invertebrate and vertebrate animals.
Narcissistic defenses are among the earliest defense mechanisms to emerge, and include denial, distortion, and projection. [4] Splitting is another defense mechanism prevalent among individuals with narcissistic personality disorder, borderline personality disorder, and antisocial personality disorder—seeing people and situations in black and white terms, either as all bad or all good.
These mechanisms were also called "ego defense mechanisms," as Sigmund Freud postulated that the ego uses these defense mechanisms to handle the conflict among the id, the ego and the super ego. Pages in category "Defence mechanisms"
Bacteria (and perhaps other prokaryotic organisms), utilize a unique defense mechanism, called the restriction modification system to protect themselves from pathogens, such as bacteriophages. In this system, bacteria produce enzymes , called restriction endonucleases , that attack and destroy specific regions of the viral DNA of invading ...
Each chemical element has a unique atomic number (Z— for "Zahl", German for "number") representing the number of protons in its nucleus. [4] Each distinct atomic number therefore corresponds to a class of atom: these classes are called the chemical elements. [5] The chemical elements are what the periodic table classifies and organizes.
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
