edge theory

a theory proposing that death anxiety has a survival function that emerges when individuals perceive themselves to be in life-threatening situations. Edge theory attempts to resolve the apparent discrepancy between other theoretical claims that death anxiety is a major motivational force and empirical studies that reveal only low to moderate levels of death anxiety in the general population. It suggests that death anxiety is the subjective or experiential side of a holistic preparation to deal with danger (symbolic of standing at the edge of the void). Heightened arousal is turned on by anxiety surges in emergency situations; psychological difficulties arise when the emergency response has permeated the individual’s everyday functioning. See also terror management theory. [introduced by Robert J. Kastenbaum]

topographic model

the original division of the psyche into three regions or systems as proposed by Sigmund Freud in 1900. The divisions are (a) the unconscious (Ucs), made up of unconscious impulses clustering around specific drives or instincts, such as hunger, thirst, and sex, as well as any repressed childhood memories associated with them; (b) the conscious (Cs), which enables the individual to adapt to society, distinguish between inner and outer reality, delay gratification, and anticipate the future; and (c) the preconscious (Pcs), which stands between the conscious and unconscious and is made up of logical, realistic ideas intermingled with irrational images and fantasies. Also called descriptive approach; systematic approach; topographic hypothesis. Compare dynamic model; economic model. See also structural model.
