To strengthen a single dissociation, a researcher can establish a "double dissociation", a term that was introduced by Hans-Lukas Teuber in 1955. [2] This is the demonstration that two experimental manipulations each have different effects on two dependent variables; if one manipulation affects the first variable and not the second, the other manipulation affects the second variable and not ...
Dissociation is commonly displayed on a continuum. [18] In mild cases, dissociation can be regarded as a coping mechanism or defense mechanism in seeking to master, minimize or tolerate stress – including boredom or conflict. [19] [20] [21] At the non-pathological end of the continuum, dissociation describes common events such as daydreaming.
Dissociation constant. In chemistry, biochemistry, and pharmacology, a dissociation constant (KD) is a specific type of equilibrium constant that measures the propensity of a larger object to separate (dissociate) reversibly into smaller components, as when a complex falls apart into its component molecules, or when a salt splits up into its ...
Dissociative adsorption is a process in which a molecule adsorbs onto a surface and simultaneously dissociates into two or more fragments. This process is the basis of many applications, particularly in heterogeneous catalysis reactions. The dissociation involves cleaving of the molecular bonds in the adsorbate, and formation of new bonds with ...
Dissociation in chemistry is a general process in which molecules (or ionic compounds such as salts, or complexes) separate or split into other things such as atoms, ions, or radicals, usually in a reversible manner. For instance, when an acid dissolves in water, a covalent bond between an electronegative atom and a hydrogen atom is broken by ...
The Multiscale Dissociation Inventory (MDI) is a comprehensive, self-administered, multiscale instrument developed by Paul F. Dell. [1] It is designed to assess the domain of dissociative phenomena. [2] The MDI measures 14 major facets of pathological dissociation and uses 23 scales to diagnose dissociative disorders. [1][3]
Dissociative identity disorder [1] [2]; Other names: Multiple personality disorder Split personality disorder: Specialty: Psychiatry, clinical psychology: Symptoms: At least two distinct and relatively enduring personality states, [3] recurrent episodes of dissociative amnesia, [3] inexplicable intrusions into consciousness (e.g., voices, intrusive thoughts, impulses, trauma-related beliefs ...
Collision-induced dissociation (CID), also known as collisionally activated dissociation (CAD), is a mass spectrometry technique to induce fragmentation of selected ions in the gas phase. [1][2] The selected ions (typically molecular ions or protonated molecules) are usually accelerated by applying an electrical potential to increase the ion ...
