In two experiments, a multicue probability learning task was used to train participants in relating judgments to a criterion, on the basis of several cues that could or could not be relevant. The outcome feedback had 25% added noise to simulate real-world experience-based learning. Judgmental strategies acquired were measured by individual multiple linear(More)

Fluorescent-labeled microspheres (FM) are a new tool for the determination of organ blood flow. However, the FM-method is labor intensive, because of the necessity to recover the microspheres from the tissue samples. The aim of this study was to automate the FM-method. A Zymate-Robotic System (Zymark, Idstein, Germany) was modified to handle a novel(More)
The need for evaluation of community psychogeriatric programs is stressed. The results of the evaluation of an outpatient service, with a liaison component, based in a community general hospital are presented. The use of treatment outcome scales, user satisfaction surveys, and a study of cost effectiveness are discussed. The issues of needs assessment,(More)
The orthogonal polarization spectral (OPS) imaging technology is a new non-invasive method to directly visualize multiple conditions of the microcirculation which has several clinical applications in humans. Quantitative measurement of the diameter of vessels, the velocity of red blood cells and functional capillary density (FCD) can be made. Activation of(More)
We report two experiments in which participants are trained using a multicue probability learning (MCPL) task, which attempts to simulate the acquisition of expert judgement by experience in the real world. Participants were asked to predict performance in certain occupations given a profile of personality test results with trial-by-trial outcome feedback.(More)
To establish the state of protonation of quinonoid species formed nonenzymically from pyridoxal phosphate (PLP) and diethyl aminomalonate, we have studied absorption spectra of the rapidly established steady-state mixture of species. We have evaluated the formation constant and the spectrum of the mixture of Schiff base and quinonoid species. For(More)
Speech endpoint detection continues to be a challenging problem particularly for speech recognition in noisy environments. In this paper, we address this problem from the point of view of fractals and chaos. By studying recurrence time statistics for chaotic systems, we find the nonstationarity and transience in a time series are due to non-recurrence and(More)
In 1989 the Bicentennial Youth Foundation (BYF) was established with the budget surplus (812.4M) of the Australian Bicentennial Authority as an independent, incorporated, non-government organisation. The Foundation's mission is to assist young Australians who are socially, financially, physically or intellectually disadvantaged to reach their full(More)
