"... the simultaneous occurrence of two sets of pressures such that compliance with one would make more difficult compliance with the other."

“Certain information is required for adequate role performance, that is, in order for a person to conform to the role expectations held by members of his role set.”

“When you’re 90 years old, you are somewhere near the end of your life; got to be... It doesn’t feel like the end yet, but statistically, demographically, there can’t be much left. But that’s not part of my daily baggage.”

“We define successful aging as including three main components: low probability of disease and disease-related disability, high cognitive and physical functional capacity, and active engagement with life.”

“Overload could be regarded as a kind of inter-sender conflict in which various role senders may hold quite legitimate expectations that a person perform a wide variety of tasks, all of which are mutually compatible in the abstract. But it may be virtually impossible for the focal person to complete all of them within given time limits. He is likely to experience overload as a conflict of priorities; he must decide which pressures to comply with and which to hold off. If it is impossible to deny any of the pressures, he may be taxed beyond the limits of his abilities. Thus overload involves a kind of person-role conflict and is perhaps best regarded as a complex, emergent type combining aspects of inter-sender and person-role conflicts.”

“Each sent pressure can be regarded as arousing in the focal person a psychological force of some magnitude and direction. Such forces will be called role forces. This is not to say that these motivational role forces are identical in magnitude and direction with the role pressures which evoked them. Especially when role pressures are seen as illegitimate or coercive, they may arouse strong resistance forces which lead to outcomes different from or even opposite to the expected behavior. Pressures to increase production rates sometimes result in slowdowns. Moreover, every person is subject to a variety of psychological forces in addition to those stimulated by pressures from his role set in the work situation. Role pressures are thus only a partial determinant of behavior on the job. In addition, to the motivational forces aroused by role pressures, there are important internal sources of motivation for role performance. One of these stems from the intrinsic satisfaction derived from the content of the role.”

“Associated with each office is a set of activities, which are defined as potential behaviors. These activities constitute the role to be performed, at least approximately, by any person who occupies that office.”
