The present work examined whether secrets are experienced as physical burdens, thereby influencing perception and action. Four studies examined the behavior of people who harbored important secrets, such as secrets concerning infidelity and sexual orientation. People who recalled, were preoccupied with, or suppressed an important secret estimated hills to be steeper, perceived distances to be f...

A relation between two secrets, known in the literature as nondeducibility, was originally introduced by Sutherland. We extend it to a relation between sets of secrets that we call independence. This paper proposes a formal logical system for the independence relation, proves the completeness of the system with respect to a semantics of secrets, and shows that all axioms of the system are logic...

We study logical principles connecting two relations: independence, which is known as nondeducibility in the study of information flow, and functional dependence. Two different epistemic interpretations for these relations are discussed: semantics of secrets and probabilistic semantics. A logical system sound and complete with respect to both of these semantics is introduced and is shown to be ...
