Adjustment, in psychology, the behavioral process by which humans and other animals maintain an equilibrium among their various needs or between their needs and the obstacles of their environments. A sequence of adjustment begins when a need is felt and ends when it is satisfied. Hungry people, for example, are stimulated by their physiological state to seek food. When they eat, they reduce the stimulating condition that impelled them to activity, and they are thereby adjusted to this particular need.
In general, the adjustment process involves four parts: (1) a need or motive in the form of a strong persistent stimulus, (2) the thwarting or nonfulfillment of this need, (3) varied activity, or exploratory behaviour accompanied by problem solving, and (4) some response that removes or at least reduces the initiating stimulus and completes the adjustment.
Social and cultural adjustments are similar to physiological adjustments. People strive to be comfortable in their surroundings and to have their psychological needs (such as love or affirmation) met through the social networks they inhabit. When needs arise, especially in new or changed surroundings, they impel interpersonal activity meant to satisfy those needs. In this way, people increase their familiarity and comfort with their environments, and they come to expect that their needs will be met in the future through their social networks. Ongoing difficulties in social and cultural adjustment may be accompanied by anxiety or depression.
