5. Percepção subjetiva de tempo durante a apreciação de música erudita ocidental: uma análise multidimensional / Subjective time perception during the appreciation of western erudite music: a multidimensional scaling
Music has been used in the research of subjective time perception because of its characteristics of temporal structure, as the rhythm, the tempo, the musical accents and others. The combination of these elements during musical listening task excite the activation of attention and memory processes involved in processing of the temporal perception. Due to the

6. Percussão e interatividade PRISMA : um modelo de esçao instrumento auto-organizado / Percussion and interactivity PRISMA : a model of a self-organized instrument-space
The contemporary development in technology makes it possible to create models for studying the correlations between stimuli and auditory, visual and spatial sensations. Numerous composers have already created compositional processes to explore these dimensions, but this is still incipient in the context of theoretical studies in music performance. Performers

8. Paradigma de equivalência de estímulos no ensino de leitura de seqüências de notas musicais
The present study investigated a procedure for teaching music notation for beginners based on the stimulus equivalence paradigm. Musical stimuli were sequences of three notes presented as sounds (A), notation in Treble Clef (B), notation in Bass Clef (C), and musical keyboard picture (D). Four undergraduate students participated in two experimental phases co

9. Atenção visual em músicos e não-músicos: um estudo comparativo
Recognition of the influence of music on cerebral function has incited neuroscientists and musicians to investigate the connections between these two areas since the 1990s. There is now a large amount of evidence indicating that cerebral neuroplastic processes can be modified as a result of musical training, which in turn can produce behavioral differences b

10. O uso da música e de estímulos vocais em pacientes em estado de coma: relação entre estímulo auditivo, sinais vitais, expressão facial e escalas de Glasgow e Ramsay. / The use of music and vocal stimuli in patients in coma state relations between auditory stimulus, vital signs, face expression and Scale of Glasgow or Scale of Ramsay.
The objectives of this work was: (1) to check the music and verbal message influence on the vital signs and face expression of the patients in physiological or induced coma; (2) connect the existence of patients responsiveness with Glasgow Coma Scale or with Ramsay Sedation Scale, considering the musical and verbal stimuli. It is a randomized controlled cl

11. Correct tonotopic representation is necessary for complex pitch perception
The ability to extract a pitch from complex harmonic sounds, such as human speech, animal vocalizations, and musical instruments, is a fundamental attribute of hearing. Some theories of pitch rely on the frequency-to-place mapping, or tonotopy, in the inner ear (cochlea), but most current models are based solely on the relative timing of spikes in the audito
