This meta-analysis examined the validity of various theoretical assumptions about cognitive and behavioral change following a communication recommending condom use. The synthesis comprised 82 treatment and 29 control groups included in 46 longitudinal reports with measures of perceived severity and susceptibility, attitudes and expectancies, norms, perceptions of control, intentions, knowledge,...

How children understand the mental state of pretense has recently become an active area of inquiry, with some research suggesting that young children do not understand that pretending is based on mentally representing some alternate state of affairs. Because intention is thought to be understood earlier than mental representation generally, these experiments tested whether children understand p...

We describe the task of intention-based text understanding for scientific argumentation. The model of scientific argumentation presented here is based on the recognition of 28 concrete rhetorical moves in text. These moves can in turn be associated with higherlevel intentions. The intentions we aim to model operate in the limited domain of scientific argumentation and justification; it is the l...

Implementation intentions specifying the replacement of a habitual response with an alternative response in a critical situation can overrule habits. In three experiments the cognitive effects of such counterhabitual implementation intentions were investigated. Results showed that implementation intentions eliminated the cognitive advantage of the habitual means in the "horse race" with the alt...

A viable model of interactive discourse must explain how interlocutors share conversational control to construct the discourse, and recognize the contributions of others to it. The position that I take in this paper is from a narrower perspective, one in which there is a primary speaker who controls and directs the discourse, but that does so while trying to accommodate the informational needs ...

Ad hoc multiagent teamwork introduces the challenge of coordinating with a variety of potential teammates, including teammates with unknown behavior. We examine the communication of policy information for enhanced coordination between such agents. The proposed decision-theoretic approach examines the uncertainty within a model of an unfamiliar teammate, identifying and acquiring policy informat...

Q Several patients who had been receiving care at the same dental office recently transferred to our practice. Although their stories were slightly different, the results appeared to be the same. For example, 1 patient stated that she had seen a new dentist for her routine examination and cleaning, and the dentist found a cavity in her lower right molar as well as in several other teeth. After ...

Intelligent mobile robots need the ability to integrate robust navigation facilities with higher level reasoning. This paper is an attempt at combining results and techniques from the areas of robot navigation and of intelligent agency. We propose to integrate an existing navigation system based on fuzzy logic with a deliberator based on the so-called BDI model. We discuss some of the subtletie...
