This paper proposes an improved query by singing/humming (QBSH) system using both melody and lyrics information for achieving better performance. Singing/humming discrimination (SHD) is first performed to distinguish singing from humming queries. For a humming query, we apply a pitch-only melody recognition method that has been used for QBSH task at MIREX with rank-1 performance. For a singing ...

Absolute pitch (AP) is the rare ability of musicians to identify the pitch of tonal sound without external reference. While there have been behavioral and neuroimaging studies on the characteristics of AP, how the AP is implemented in human brains remains largely unknown. AP can be viewed as comprising of two subprocesses: perceptual (processing auditory input to extract a pitch chroma) and ass...

Musical pitch identification was investigated in two experiments in which absolute pitch (AP) possessors and nonpossessors categorized tones presented in isolation into predetermined pitch classes. Stimuli consisted of 60 different tones per octave (at intervals of 20 cents). The experiments were designed to minimize the possibility that subjects could use strategies other than AP in perfi~rmin...

Emotion discrimination, emotion regulation, and cognitive control are three related, yet separable processes that emerge over the course of development. The current study tested 100 children, adolescents, and adults on an Emotional Go/Nogo task, illustrating the ability of this paradigm to identify the unique developmental patterns for each of these three processes in the context of both positi...

Different groups of adult rats were subjected to discrete lesions in one of ten different areas of the brain which have previously been found to be implicated in retention of learned brightness and pattern discrimination habits. When tested for the rodent's predictable (instinctive) preference for the dark, eight groups showed deficient preference scores and two showed preference scores compara...

Vocalizations of blue whales were recorded with a cabled hydrophone array at Pioneer Seamount, 50 miles off the California coast. Most calls occurred in repeated sequences of two-call pairs (A, then B). The B call is a frequency-modulated tone highly repeatable in form and pitch. A model of this sound is described which permits detecting very small frequency shifts. B calls are found to be alig...

The present study tested Japanese 4.5- and 10-month old infants' ability to discriminate three German vowel pairs, none of which are contrastive in Japanese, using a visual habituation-dishabituation paradigm. Japanese adults' discrimination of the same pairs was also tested. The results revealed that Japanese 4.5-month old infants discriminated the German /bu:k/-/by:k/ contrast, but they showe...

BACKGROUND AND PURPOSE The aim of this study was to identify the mechanism underlying the auditory discriminatory process reflected in mismatch negativity (MMN), using time-frequency analysis of single-trial event-related potentials (ERPs). METHODS Two auditory tones of different probabilities (oddball paradigm) and the same probability (control paradigm) were used. The average dynamic change...

AND CONCRETE SCHIZOPHRENICS 331 formulated a mediating-response theory of human discrimination learning. Mediatingresponse theory postulates that, in the process of discrimination learning, an implicit mediating S-R association is forced by which Ss learn to respond to a particular stimulus dimension. Since, in an R shift, the relevant dimension does not change, an R shift should be learned fas...
