A ®eld experiment demonstrated that forming implementation intentions was e€ective in changing complex everyday behavior, in this case establishing a healthier diet. Implementation intentions concerned a speci®c plan for when and how to act. The e€ect of implementation intentions was additive to the prediction of healthy eating by behavioral intentions to eat healthily. Implementation intention...

We report on a study investigating the relationships among query reformulations and different search intentions during an information seeking session. Twenty-four participants were each asked to search for information useful for two (of four) different journalism tasks; after completing each search, the search was replayed, and participants were asked to specify what they intended to accomplish...

An online experiment (n=1,897) was carried out to understand how data disclosure practices in ubiquitous surveillance affect users' privacy concerns. Information about the identity and intentions of a data collector was manipulated in hypothetical surveillance scenarios. Privacy concerns were found to differ across the scenarios and moderated by knowledge about the collector's identity and inte...

The SharedPlans theory provides an axiomatic framework of collaborative plans based on four types of intentional attitudes. However, there still lacks an adequate semantics for the ‘potential intention’ operators. In this paper, we give a formal semantics to potential intentions, and examine models that can validate various relations between beliefs, intentions, and potential intentions. Introd...

We introduce a logic for temporal beliefs and intentions based on Shoham’s database perspective. We separate strong beliefs from weak beliefs. Strong beliefs are independent from intentions, while weak beliefs are obtained by adding intentions to strong beliefs and everything that follows from that. We formalize coherence conditions on strong beliefs and intentions. We provide AGMstyle postulat...
