Various stimulus types have been investigated in pitch discrimination and pitch matching tasks. However, previous studies have not explored the use of recorded samples of an individual's own voice in performing these two tasks. The purpose of this study was to investigate pitch discrimination and pitch matching abilities using three stimuli conditions (participant's own voice, a neutral female ...

OBJECTIVE To investigate how anti-discrimination legislation in the form of the UK Disability Discrimination Act (DDA) affected socioeconomic disparities in the employment rates of people with a limiting long-term illness (LLTI) or disability. DESIGN National cross-sectional data on employment rates for people with and without an LLTI or disability were obtained from the General Household Sur...

A brightness discrimination experiment was performed to examine how subjects decide whether a patch of pixels is "bright" or "dark," and stimulus duration, brightness, and speed versus accuracy instructions were manipulated. The diffusion model (Ratcliff, 1978) was fit to the data, and it accounted for all the dependent variables: mean correct and error response times, the shapes of response ti...

Important to Western tonal music is the relationship between pitches both within and between musical chords; melody and harmony are generated by combining pitches selected from the fixed hierarchical scales of music. It is of critical importance that musicians have the ability to detect and discriminate minute deviations in pitch in order to remain in tune with other members of their ensemble. ...

Previous studies on tones suggest that Mandarin listeners are more sensitive to pitch direction and slope while English listeners primarily attend to pitch height. In this study, just noticeable differences were established for pitch discrimination using a three-interval, forced-choice procedure with a two-down, one-up staircase design. A high rising and a high falling Mandarin tone were manipu...

The study examined third-party listeners' ability to detect the Hellos spoken to prevalidated happy, neutral, and sad facial expressions. The average detection accuracies from the happy and sad (HS), happy and neutral (HN), and sad and neutral (SN) listening tests followed the average vocal pitch differences between the two sets of Hellos in each of the tests; HS and HN detection accuracies wer...

OBJECTIVE The Heidelberg Phoneme Discrimination Test (HLAD), developed and standardized in 1998, is widely used in the differential diagnosis of dyslexia. Normative data have only been available for children of the 2nd and 4th grades, while norms for the 3rd grade are still missing. PATIENTS AND METHODS We assessed three HLAD subtests [auditory phoneme discrimination, kinesthetic phoneme disc...

This study compares the efficiency and plausibility of published computational models of familiarity discrimination in the perirhinal cortex. Substantial evidence indicates that the perirhinal cortex is involved in both the familiarity discrimination aspect of recognition memory and in perceptual functions involved with representations of complete stimuli (i.e., object identification). Publishe...

Discrimination of the direction of motion of a noisy stimulus is an example of sensory discrimination under uncertainty. For stimuli that are extended in time, reaction time is quicker for larger signal values (e.g., discrimination of opposite directions of motion compared with neighboring orientations) and larger signal strength (e.g., stimuli with higher contrast or motion coherence, that is,...

The effect of Pavlovian discrimination training with two stimuli upon subsequent learning of an operant discrimination involving those stimuli was studied. After preliminary lever press training, the lever was removed and thirsty rats received noncontingent pairings between S(1) (a tone or a clicker) and water reinforcements, whereas S(2) (a clicker or a tone) occurred always without reinforcem...
