Introduction Enhanced auditory perception in musicians is likely to result from auditory perceptual learning during several years of training and practice. Many studies have focused on biological processing of auditory stimuli among musicians. However, there is a lack of literature on temporal resolution and active auditory discrimination skills in vocal musicians. Objective The aim of the pres...

Two groups of rabbits were trained on a brightness discrimination task. A two-choice discrimination apparatus was used. By means of food reward one group of rabbits was trained to open the darkest gate, the other was trained to open the brightest gate. The second group learned significantly faster than the first one.

Area under an ROC curve plays an important role in estimating discrimination performance – a well-known theorem by Green (1964) states that ROC area equals the percentage of correct in two-alternative forcedchoice setting. When only single data point is available, the upper and lower bound of discrimination performance can be constructed based on the maximum and minimum area of legitimate ROC c...

With training, an observer's ability to discriminate similar directions of motion gradually improves. A series of studies reveals that this improvement, (1) is restricted to the trained direction and other, similar directions, (2) persists for at least several months, (4) shows appreciable, but not complete, transfer between the two eyes, and (5) is largely restricted to the stimulated region o...

Disability, Gender and the Labour Market Using data from the 2002 LFS, we examine the impact of disability on labour market outcomes by gender. Our results indicate that substantial differences in both the likelihood of employment and levels of earnings exist, despite several years of operation of the Disability Discrimination Act. Significant heterogeneity within the disabled group is identifi...

A comprehensive account of wavelength discrimination and colour saturation discrimination is given in terms of optimum probabilistic signal detection. The theory is a logical deduction from statistical estimation theory of the visual estimate of the spectral parameters of the stimulus. In place of geometrical concepts associated with colour-space geometry, stimulus discriminability is determine...

Musical priming research has reported that sensory consonance/dissonance judgements for a target chord were faster when targets were musically related to a musical prime context. The present study extended this context effect to a timbre discrimination task. This new task allowed us to investigate whether musical priming results from congruency effects similar to those reported in other domains...

OBJECTIVE The two most frequent hypochromic microcytic anemias are β- thalassemia minor (BTM) and iron deficiency anemia (IDA). Several discrimination indices have been proposed to quickly discriminate these similar entities via parameters obtained from automated blood count analyzers. The aim of this study to evaluate the diagnostic reliability of ten discrimination indices in the differentiat...

The association between racial discrimination and mental health was examined using Wave 2 (1987–1988) and Wave 3 (1988–1989) panel data from the National Survey of Black Americans (NSBA). Mental health status was assessed by psychological distress and depression. In cross-sectional analyses, the perception of * Direct all correspondence to Tony N. Brown, P.O.

The effect of task duration on odor discrimination in aging was studied. Twenty-seven young male adults and 24 young female adults between 18 and 30 years of age, and 17 older male adults between 45 and 65 years of age completed an odor discrimination task. The odor discrimination task consisted of two parts of 16 trials each in which, from three bottles consisting of two identical and one aber...
