life space
in the field theory of Kurt Lewin, the “totality of possible events” for one person at a particular time; a person’s possible options together with the environment that contains them. The life space is a representation of the environmental, biological, social, and psychological influences that define one person’s unique reality at a given moment in time. Contained within the life space are positive and negative valences, that is, forces or pressures on the individual to approach a goal or move away from a perceived danger.
