We present a probabilistic model to monitor a user’s emotions and engagement during the interaction with educational games. We illustrate how our probabilistic model assesses affect by integrating evidence on both possible causes of the user’s emotional arousal (i.e., the state of the interaction) and its effects (i.e., bodily expressions that are known to be influenced by emotional reactions)....

Many advances in argumentation theory have been made, but the exponential complexity of argumentation-based reasoning has made it impractical to apply argumentation theory. In this paper, we propose a binary decision diagram (BDD) approach to argumentation-based reasoning. In the approach, sets of arguments and defeats are encoded into BDDs so that an argumentation process can work on a set of ...

Backtracking influence is influence that zigzags in time. For example, backtracking influence exists when an event E1 makes an event E2 more likely by way of a nomic connection that goes from E1 back in time to an event C and then forward in time to E2. I contend that backtracking influence is redundant in the sense that any existing backtracking influence exerted by E1 on E2 is equivalent to E...

If the influence diagram (ID) depicting a Bayesian game is common knowledge to its players then additional assumptions may allow the players to make use of its embodied irrelevance statements. They can then use these to discover a simpler game which still embodies both their optimal decision policies. However the impact of this result has been rather limited because many common Bayesian games d...

This paper proposes a high-speed architecture to realize two-variable numeric functions. It represents the given function as an edgevalued multiple-valued decision diagram (EVMDD), and shows a systematic design method based on the EVMDD. To achieve a design, we characterize a numeric function f by the values of l and p for which f is an l-restricted Mp-monotone increasing function. Here, l is a...

The “Hedonistic Paradox” states that homo economicus, or someone who seeks happiness for himor herself, will not find it, but the person who helps others will. This study examines two questions in connection with happiness and generosity. First, do more generous people, as identified in dictator experiments, report on average greater happiness, or subjective well-being, as measured by responses...

Failure to express minority views may distort the behavior of company boards, committees, juries, and other decision-making bodies. Devising a new experimental procedure to measure such conformity in a judgment task, we compare the degree of conformity in groups with varying gender composition. Overall, our experiments offer little evidence that gender composition affects expression of minority...

A model of affect and learning for intelligent tutoring systems is proposed. The model considers both how a student feels and what a student knows, and then customizes how instruction is presented and how learning and performance are reinforced. The model was designed based on teachers’ expertise, which was obtained through interviews and interaction with an educational game on number factoriza...

We investigate the complexity of temporal defeasible logic, and propose an efficient algorithm to compute the extension of any theory. The logic and algorithm are discussed in regard to modeling deadlines and normative retroactivity.

In this paper, we present trends in IS research during a 10-year period (2004 to 2013). Much like its predecessor, Palvia et al. (2004), we provide a long-overdue update. We reviewed all papers from seven major IS journals and coded them based on topics studied, methodologies used, models rendered, and paradigmatic approaches taken. We captured trends in IS research and compared them to previou...
