Some systems are strange, near-bugs that turn out upon deeper analysis to be absolutely fundamental. This paper develops the notion of strangeness with respect to one class of AI system, cognitive architectures. It describes the detection of strange new architectures and their synthesis with conventional architectures. It also inventories strategies for the deliberate design of strange new arch...

Within the general objective of conceiving a cognitive architecture for image interpretation able to generate outputs relevant to several target user profiles, the paper elaborates on a set of operations that should be provided by a cognitive space to guarantee the generation of relevant descriptions. First, it attempts to define a working definition of contrast operation. Then, revisiting well...

OBJECTIVE The effects of fatigue on multiple-task performance were explored through computational cognitive modeling. BACKGROUND Fatigue typically has a negative impact on human performance. Biomathematical models exist that characterize the dynamics of human alertness, but the link between alertness and in situ performance on specific tasks is tenuous. Cognitive architectures offer a princip...

While computational cognitive modeling has made great strides in addressing complex dynamic tasks, the modeling of individual differences in complex tasks remains a largely unexplored area of research. In this paper we present a straightforward approach to modeling individual differences, specifically age-related cognitive differences, in complex tasks, and illustrate the application of this ap...

In this chapter we discuss how the ACT-R cognitive architecture can be used in combination with fMRI data. ACT-R is a cognitive architecture that can provide a description of the processes from perception through to action for a wide range of cognitive tasks. It has a computational implementation that can be used to create models of specific tasks, which yield exact predictions in the form of r...

Herein I sketch out the foundations of a computational theory of pretense, where pretense is broadly defined as pretend-play. In keeping with the sizable literature on the topic, I assume that pretending involves a number of distinct features that include the intentional decoupling of pretense from reality. A scenario is presented that involves all of what have been claimed to be necessary cond...

This paper aims to determine whether iconic tracing gestures produced while speaking constitute part of the speaker’s communicative intention. We used a picture description task in which speakers must communicate the spatial and color information of each picture to an interlocutor. By establishing the necessary minimal content of an intended message, we determined whether speech produced with c...

The traditional view of intelligent behaviours as products of pure rational processes fails when trying to explain most of human behaviours, in which emotion plays a key role. However, emotional factors add an extra complexity to agent architectures, making them, hitherto, either few efficient or few reusable. This paper presents a context independent cognitive architecture for agents combining...
