Both the speed and the accuracy of a perceptual judgment depend on the strength of the sensory stimulation. When stimulus strength is high, accuracy is high and response time is fast; when stimulus strength is low, accuracy is low and response time is slow. Although the psychometric function is well established as a tool for analyzing the relationship between accuracy and stimulus strength, the...

Patients with borderline personality disorder have unstable emotions, difficulty maintaining relationships and a high probability of self-inflicted damage. A recent experiment of Posner et al. that measured reaction-time differences derived from a simple task, revealed that alerting and orienting is normal in these patients. By contrast, and perhaps at the root of this personality disorder, the...

Since W. Wundt (1904) and H. J. Watt (1906), researchers have found no agreement on how goals direct word retrieval. A prevailing associative account (E. K. Miller & J. D. Cohen, 2001) holds that goals bias association strength, which determines retrieval latency and whether irrelevant words interfere. A symbolic account (A. Roelofs, 2003) holds that goals enable retrieval rules and predicts no...

In the development of safety-critical embedded systems, the ability to formally analyze system behavior models, based on timing and causality, helps the designer to get insight into the systems overall timing behavior. To support the design and analysis of real-time embedded systems, the UML modeling profile MARTE provides CCSL – a time model and a clock constraint specification language. CCSL ...

In this paper, several experiments on F0 transformation within the voice conversion framework are presented. The conversion system is based on a probabilistic transformation of line spectral frequencies and residual prediction. Three probabilistic methods of instantaneous F0 transformation are described and compared. Moreover, a new modification of inter-speaker residual prediction is proposed ...
