Psychological construction constitutes a different paradigm for the scientific study of emotion when compared to the current paradigm that is inspired by faculty psychology. This new paradigm is more consistent with the post-Darwinian conceptual framework in biology that includes a focus on (a) population thinking (vs. typologies), (b) domain-general core systems (vs. physical essences), and (c...

Nowadays, more and more artificial agents integrate emotional abilities, for different purposes: expressivity, adaptability, believability... Designers mainly use Ortony et al.’s typology of emotions, that provides a formalization of twenty-two emotions based on psychological theories. But most of them restrain their agents to a few emotions among these twenty-two ones, and are more or less fai...

Emotional agents are an active research domain, with direct application in several industrial fields such as video games, interactive environments or enhanced human computer interactions. Emotional behavior should consider both the representation of the emotions and the mood states. There are two mostly accepted, and used, cognitive psychological models for this: OCC model and PAD model.Based o...

Although popular among computer scientists, the OCCmodel of emotions contains a number of ambiguities that stand in the way of a truthful formalization or implementation. This paper aims to identify and clarify several of these ambiguities. Furthermore, a new inheritance-based view of the logical structure of emotions of the OCC model is proposed and discussed.

This paper describes how personalities influence the behaviour of emotional agents. Two different emotional models are discussed, namely the OCC emotion model and the emotion-connectionist model. In both models personalities changes the behaviour on a different way. This paper also presents an implementation of a prototype to evaluate the performance of the different personalities in the emotio...

The One Class Classification (OCC) problem is different from the conventional binary/multi-class classification problem in the sense that in OCC, the negative class is either not present or not properly sampled. The problem of classifying positive (or target) cases in the absence of appropriately-characterized negative cases (or outliers) has gained increasing attention in recent years. Researc...

In trying to build increasingly believable autonomous characters for virtual environments, researchers successfully explored the use of emotional systems to endow their agents with emotional capabilities. Of relevant notice are the ability to experience and express emotions, and the ability to use its emotions to influence decision-making. These systems are often based in appraisal theories, su...

In this paper, we provide a logical formalization of the emotion triggering process and of its relationship with mental attitudes, as described in Ortony, Clore, and Collins’s theory. We argue that modal logics are particularly adapted to represent agents’ mental attitudes and to reason about them, and use a specific modal logic that we call Logic of Emotions in order to provide logical definit...

This paper presents an educational system that incorporates two theories namely SAW and OCC in order to provide an improved affective e-learning environment. Simple additive Weighting (SAW) is used for the recognition of possible emotional states of the users, while the cognitive theory of emotions (OCC) is used for the generation of emotional states by educational agents. The system bases its ...
