While spatial neglect most commonly occurs after right hemisphere lesions, damage to diverse areas within the right hemisphere may lead to neglect, possibly through different mechanisms. To identify potentially different causes of neglect, the visual information used (the 'perceptual template') in a cueing task was estimated with a novel technique known as 'classification images' for five norma...

The present paper describes a case of late pitch peak placement in West Swedish. In the Swedish prosodic typology this dialect type belongs to the double-peaked dialects, where the first pitch peak of a word in focus represents word accent proper and the second peak focal accent. In phrase-final position the focal accent H appears to seek the edge of the phrase, while in nonfinal position it se...

To examine three problems in the interpretation of the Luria-Nebraska Neuropsychological Battery (LNNB), the normal participants from four different studies were pooled to form a sample of 241 LNNB profiles. The first problem addressed was the LNNB's false positive rate. All five yes/no decision rules were applied simultaneously. Each individual rule had a 0% to 8% false positive rate: combinin...

Logistic regression is a statistical modelling technique which may be applied to estimate the simultaneous effect of a set of predictors (e.g. gestational age, birthweight) on the risk of a certain outcome variable (e.g. neonatal death) which can take either one of two possible values (yes/no, alive/dead) or in the situation where one wants to estimate the effect of a particular risk factor (e....

The capability to foster metacognitive evaluations (MEs) of oneself and others represents a major component of conscious awareness. Separate emerging lines of brain activation research examining ME have converged on the medial prefrontal cortex as a common finding. The current functional magnetic resonance imaging (fMRI) study utilized a task that directly compared ME associated with two refere...

INTRODUCTION The group practice physicians in Marathon, a small rural community in northwestern Ontario, discovered general lifestyle dissatisfaction with the traditional model for obstetric practice. The old model of doing the follow-up and delivery for one's own patients created perceived onerous on-call responsibilities. The providers created a new model of obstetric care. This involved the ...

Phonology provides a system by which a limited number of types of phonetic variation can signal communicative intentions at multiple levels of linguistic analysis. Because phonologies vary from language to language, acquiring the phonology of a language demands learning to attribute phonetic variation appropriately. Here, we studied the case of pitch-contour variation. In English, pitch contour...

While visual signals that accompany spoken language serve to augment the communicative message, the same visual ingredients form the substance of the linguistic system in sign languages. This article provides an analysis of visual signals that comprise part of the intonational system of a sign language. The system is conveyed mainly by particular actions of the upper face, and is shown to patte...

This paper describes a way of using intonation and dialog context to improve the performance of an automatic speech recognition (ASR) system. Our experiments were run on the DCIEM Maptask corpus, a corpus of spontaneous task-oriented dialog speech. This corpus has been tagged according to a dialog analysis scheme that assigns each utterance to one of 12 "move types," such as "acknowledge," "que...

The first work presented in this document studies the opacity of purely probabilistic systems. i.e. systems in which the non-deterministic choices have been replaced by probabilistic distribution over the set of states. The notion of opacity has been previously studied in the case of non-deterministic transition systems to determine whether a system respects some security properties. The idea i...
