In sign language research, technically it has been possible to investigate prominence around a unit of sign movements that realizes strong visual impression. Based on the researches of speech prominence, this study proposes techniques to delimit a sequential hand-movement into small units, and investigates the prominence by the comparisons of physical properties on each unit between emphasized ...

A novel connectionist model of sentence production is presented, which employs rich situation model representations originally proposed for modeling systematicity in comprehension (Frank, Haselager, & van Rooij, 2009). The high overall performance of our model demonstrates that such representations are not only suitable for comprehension, but also for modeling language production. Further, the ...

This study examines pragmatic language production deficits in people with Parkinson’s disease (PD). Participants (PD and non-PD) were interviewed and their responses coded for degree of informativeness. PD participants were more under-informative than non-PD participants. Response underinformativeness was associated with decreased executive control, mental status, and speech act comprehension m...

Abs t rac t : It has been claimed that product ion systems have severa l advantages over other representat ional schemes. These include the potent ial for general self-augmentat ion (i.e., learn ing of new behavior) and the abil i ty to funct ion in complex env i ronments. The product ion system language, OPS, was implemented to test these claims. In this paper we exp lo re some of the issues t...

Wikis represent a particular type of collaborative learning environment where collaboration can result in aggregated, collective products. This study makes the claim that such potential challenges language production practices in school where the individual learner’s output is often the focus of attention. The argument is put forth by juxtaposing theory, literature review, and videotaped wiki a...

Listeners use linguistic feedback to provide evidence of understanding to speakers. They, in turn, use it to reason about listeners’ mental states, to determine the groundedness of communicated information and to adapt subsequent utterances to the listeners’ needs. We describe a probabilistic model for the interpretation of listener feedback in its dialogue context that enables a speaker to eva...

The Congruent Interaction Matrix (CIM) model is being formulated to represent knowledge updating and language production. The line of research taken in this paper is limited to a set of questions restricted to concepts and actions that can be used in modeling human language behavior. The Congruent Interaction Matrix model introduced here proposes virtual structures represented as matrices. The ...

MUMBLE Is a general purpose subsystem Intended as the final output segment of the natural language interface of an expert system. As described in [1], it takes plans expressed in nearly any conceptual representation and realizes them as English texts, integrating the different parts of the plan linguistically as well as taking full responsibility for the grammatically of the output and its cohe...

The representation of speech goals was explored using an auditory feedback paradigm. When talkers produce vowels the formant structure of which is perturbed in real time, they compensate to preserve the intended goal. When vowel formants are shifted up or down in frequency, participants change the formant frequencies in the opposite direction to the feedback perturbation. In this experiment, th...
