This study involved playing and listening (using recorded sounds) experiments to investigate how changes in soundpost length (for a fixed position) affect the perceptual qualities of violin what threshold change is below which players luthiers do not perceive differences. A length-adjustable carbon fiber was employed. During experiment, subjects played provided on modified by experimenter find ...

A focus group study with 37 residents of Manhattan, Kansas, was conducted to examine consumers' risk perceptions of foodborne illnesses from eating beef. The four focus-group sessions were designed to determine (1) relative preferences for alternative combinations of public food safety measures (Hazard Analysis Critical Control Points [HACCP], carcass pasteurization, irradiation) and private pr...

We studied perception in three patients with prosopagnosia of childhood onset. All had trouble with other 'within-category' judgments. All were deficient on face matching tests and severely impaired on tests of perception of the spatial relations of facial features and abstract designs, indicating a deficit in the encoding of coordinate relationships, similar to adult-onset prosopagnosia with l...

For testing the programs students were screened for their space perception, and then performed paper tests. One group was permitted to practice using the virtual reality programs; the other used only traditional tutorial methods. A second paper test was then performed. The evaluation of the two tests showed that the possibility of using the virtual reality programs increased the space perceptio...

Background: Variability in speech performance is a major concern for children with cochlear implants (CIs). Spectral resolution is an important acoustic component in speech perception. Considerable variability and limitations of spectral resolution in children with CIs may lead to individual differences in speech performance. The aim of this study was to assess the correlation between auditory ...

Affect perception deficits have been extensively documented in schizophrenia and are associated with the social dysfunction that is characteristic of this disorder. The two previous studies examined facial affect perception in genetically at-risk samples and yielded mixed results. The current study was designed to provide a rigorous test of affect perception abilities among schizophrenia patien...

BACKGROUND Drug name confusion is a common type of medication error and a persistent threat to patient safety. In the USA, roughly one per thousand prescriptions results in the wrong drug being filled, and most of these errors involve drug names that look or sound alike. Prior to approval, drug names undergo a variety of tests to assess their potential for confusability, but none of these preap...

This study aims at investigating the perception and production of the English nasals /m/ and /n/ in syllable-final position by 20 Brazilian EFL learners and 3 native speakers of American English. Perception was assessed by means of both a discrimination and an identification test. Production data was collected by means of a Sentence Reading Test. The results from the perception tests revealed t...
