The status of perceptual priming and word-completion priming in patients with Alzheimer's disease (AD) was examined. Experiment 1 established the reliability of the perceptual priming measure in normal subjects. In Experiment 2, AD patients showed a normal magnitude of perceptual priming. In Experiment 3, a single group of AD patients showed a normal magnitude of perceptual priming and impaired...

When items are presented sequentially, the evaluation of current item is biased by both previous item’s value (perceptual bias) and response given (response bias). While these biases have been identified in judgements facial attractiveness, it unclear as to whether they produce assimilation and/or contrast effects. Here, two tasks were employed measure each bias isolation. By presenting a prece...

The perception of speech is notably malleable in adults, yet alterations in perception seem to have little impact on speech production. However, we hypothesized that speech perceptual training might immediately influence speech motor learning. To test this, we paired a speech perceptual-training task with a speech motor-learning task. Subjects performed a series of perceptual tests designed to ...

Perceptual load has been found to be a powerful determinant of distractibility in laboratory tasks. The present study assessed how the effects of perceptual load on distractibility in the laboratory relate to individual differences in the likelihood of distractibility in daily life. Sixty-one subjects performed a response-competition task in which perceptual load was varied. As expected, indivi...

Image restoration algorithms are typically evaluated by some distortion measure (e.g. PSNR, SSIM) or by human opinion scores that directly quantify perceived perceptual quality. In this paper, we prove mathematically that distortion and perceptual quality are at odds with each other. Specifically, we study the optimal probability for discriminating the outputs of an image restoration algorithm ...

Instead of using citations or marketing academics’ perceptual ranking of journals, this article examines the ranking of marketing journals using Australian university library holdings, in either hard copy or full-text electronic format. This measure was used as a proxy for broad-based accessibility of marketing journals. The study found that the accessibility rankings differed significantly fro...

This paper describes a method for analysing the perceptual relevance of parameter variations of the Liljencrants– Fant (LF) model for the glottal pulse. A perceptual distance measure based on excitation patterns was developed and evaluated in order to predict audibility discrimination thresholds for small changes to the R-parameters of the LF model. For a number of R-parameter sets, taken from ...
