Social penetration theory

Altman is famous for his work with Taylor resulting in the social penetration theory, which generally states that as relationships develop, communication moves from relatively shallow, non-intimate levels to deeper, more personal levels. If conversation is pleasant and rewarding, people will offer more information about themselves to each other that covers more areas of their life and is more sensitive to them.

Environmental psychology Altman also did work in the field of environmental psychology. He believes there is a strong relationship between environmental psychology and social psychology and that the two disciplines have much to offer each other. Altman's Human Behavior and the Environment series added volumes on intellectual traditions (Altman & Christensen 1990), place attachment (Altman & Low 1992), and women and the environment (Altman & Churchman 1994). Much of his work following his Social Penetration Theory looked at human behavior and interactions with the environment.
