The contribution of different harmonics to pitch salience in a musical context was examined by requiring subjects to discriminate a small (1/4 semitone) pitch change in one note of a melody that repeated in transposition. In Experiment 1, performance was superior when more harmonics were present (first five vs. fundamental alone) and when the second harmonic (of tones consisting of the first tw...

Rabbits were trained to discriminate striated patterns of different orientation in a two-choice discrimination box. After the 90% correct level had been reached, motor behaviour was studied during visual discrimination. It was found that the animals made their decision after seeing one of the two stimuli. This finding is in disagreement with an earlier study from which it was concluded that the...

Fifteen patients with prominent positive symptoms of schizophrenia and 15 normal controls performed verbal prosodic and pure musical discrimination tasks, with changes in pitch and timing parameters. The patients' performance was comparable to that of controls on the discrimination of terminal pitch changes, but significantly poorer on the more difficult internal pitch discrimination. The latte...

Music and language share many attributes and a large body of evidence shows that sensitivity to acoustic cues in music is positively related to language development and even subsequent reading acquisition. However, such association was mainly found in alphabetic languages. What remains unclear is whether sensitivity to acoustic cues in music is associated with reading in Chinese, a morphosyllab...

The effects of aging on decision time were examined in a brightness discrimination experiment with young and older subjects (ages, 60-75 years). Results showed that older subjects were slightly slower than young subjects but just as accurate. Ratcliff's (1978) diffusion model was fit to the data, and it provided a good account of response times, their distributions, and response accuracy. There...

n engl j med 368;18 nejm.org may 2, 2013 1670 missible, whereas discrimination on other grounds is only morally blameworthy, but these cases are newsworthy precisely because they are so unexpected from a profession with a strong tradition of helping people in need and rejecting the stigmas that may bias other members of society. Fortunately, most physicians take this tradition and their profess...

This paper describes techniques for massively parallel parsing where sequences of lexical categories are assigned to single processors and compared in parallel to a given input string. Because ven small grammars result in full expansions that are much larger than the largest existing massively parallel computers, we need to develop techniques for "doubling up" sequences on processors so that th...

The aims of this study were to identify the level of interexaminer agreement among preclinical operative dentistry faculty members when grading Class II preparations performed by first-year dental students; to develop discrimination exercises for specific preparation components where interexaminer agreement was poor; and to evaluate if the discrimination exercises were able to improve inter- an...

Based on the resource theory for quantifying coherence of quantum channels, we introduce a new quantifier channels via maximum relative entropy. We prove that entropy is directly related to maximally coherent under particular class superoperations, which results in an operational interpretation channels. also conception sub-superchannels and sub-superchannel discrimination. For any show advanta...

In this paper we consider discrimination-aware classification of educational data. Mining and using rules that distinguish groups of students based on sensitive attributes such as gender and nationality may lead to discrimination. It is desirable to keep the sensitive attributes during the training of a classifier to avoid information loss but decrease the undesirable correlation between the se...
