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.
People develop two or more distinct identities, with a dissociation between the personalities, Tierney says. Dissociative amnesia involves an inability to recall information, beyond forgetfulness.
A second area of discussion surrounds the question of whether there is a qualitative or quantitative difference between dissociation as a defense versus pathological dissociation. Experiences and symptoms of dissociation can range from the more mundane to those associated with post traumatic stress disorder (PTSD) or acute stress disorder (ASD ...
The effects of dissociatives can include sensory dissociation, hallucinations, mania, catalepsy, analgesia and amnesia. [4] [5] [6] According to Pender (1972), "the state has been designated as dissociative anesthesia since the patient truly seems disassociated from his environment."
Relationships between childhood abuse, disorganized attachment, and lack of social support are thought to be common risk factors leading to dissociative identity disorder. [29] Although the role of a child's biological capacity to dissociate remains unclear, some evidence indicates a neurobiological impact of developmental stress.
The only difference between dissociative amnesia, dissociative identity disorder and dissociative fugue is that the person affected by the latter travels or wanders. This traveling or wandering is typically associated with the amnesia-induced identity or the person's physical surroundings.
Dissociative amnesia or psychogenic amnesia is a dissociative disorder "characterized by retrospectively reported memory gaps. These gaps involve an inability to recall personal information, usually of a traumatic or stressful nature."
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 ...
