Of 500 left brain-damaged patients with educational level above elementary school investigated with a standard quantitative battery for dissociation between oral and written expression, speech was found to be selectively impaired in seven (three with "pure anarthria," two with anarthria in the context of Broca's aphasia, and two with fluent aphasia with remarkable sparing of writing), and writi...

The Fluent Calculus has largely been focused on building agents that work individually. However, agents often need to interact with each other to learn more about their environment as well as to achieve their goals. One form of interaction is by means of communication. Effective, goal–oriented communication requires knowledge of other agents. This paper studies the problem of endowing agents wi...

The present study examined whether infant-directed (ID) speech facilitates intersensory matching of audio-visual fluent speech in 12-month-old infants. German-learning infants' audio-visual matching ability of German and French fluent speech was assessed by using a variant of the intermodal matching procedure, with auditory and visual speech information presented sequentially. In Experiment 1, ...

Williams Syndrome (WS) is a neurodevelopmental disorder of known genetic origin, characterized by serious delays in language onset yet relatively verbose, intelligible and fluent speech in late childhood and adulthood. How do motor abilities relate to language in this group? We investigated planning and co-ordination of the movement of the speech articulators (oromotor praxis) in 28 fluent-spea...

This work involves two areas of research in computer science, namely Knowledge Representation and Logic Programming. Starting from the formalism proposed in Features & Fluents by Erik Sandewall for describing and reasoning about Inhabited Dynamical Systems, we try to reconstruct it within a Logic Programming framework. The result is an extended logic programming language called Fluent Logic Pro...

When drawing conclusions about narratives, minimizing|to a reasonable extent|the occurrence of events is crucial. We argue that unguided minimization is insuucient in case events are causally connected, for it easily fails to distinguish unmotivated event occurrences from those that have a cause. Two solutions are ooered, the rst of which has the advantage of being straightforwardly realized bu...

We introduce a new action language, CARD, which allows defeasible dynamic causal laws, default fluents, concurrent and non-deterministic actions, and actions which use resources. We give syntax and semantics of the language and several simple examples of its use. Comparison with some other languages is also given though limited by space requirements.

We discuss the persistence of the indirect effects of an action—the question when such effects are subject to the commonsense law of inertia, and how to describe their evolution in the cases when inertia does not apply. Our model of nonpersistent effects involves the assumption that the value of the fluent in question is determined by the values of other fluents, although the dependency may be ...

We describe the new version of the PDDL-to-ASP translator plasp. First, it widens the range of accepted PDDL features. Second, it contains novel planning encodings, some inspired by SAT planning and others exploiting ASP features such as well-foundedness. All of them are designed for handling multivalued fluents in order to capture both PDDL as well as SAS planning formats. Third, enabled by mu...
