Action-based effects on music perception

The classical, disembodied approach to music cognition conceptualizes action and perception as separate, peripheral processes. In contrast, embodied accounts of music cognition emphasize the central role of the close coupling of action and perception. It is a commonly established fact that perception spurs action tendencies. We present a theoretical framework that captures the ways in which the human motor system and its actions can reciprocally influence the perception of music. The cornerstone of this framework is the common coding theory, postulating a representational overlap in the brain between the planning, the execution, and the perception of movement. The integration of action and perception in so-called internal models is explained as a result of associative learning processes. Characteristic of internal models is that they allow intended or perceived sensory states to be transferred into corresponding motor commands (inverse modeling), and vice versa, to predict the sensory outcomes of planned actions (forward modeling). Embodied accounts typically refer to inverse modeling to explain action effects on music perception (Leman, 2007). We extend this account by pinpointing forward modeling as an alternative mechanism by which action can modulate perception. We provide an extensive overview of recent empirical evidence in support of this idea. Additionally, we demonstrate that motor dysfunctions can cause perceptual disabilities, supporting the main idea of the paper that the human motor system plays a functional role in auditory perception. The finding that music perception is shaped by the human motor system and its actions suggests that the musical mind is highly embodied. However, we advocate for a more radical approach to embodied (music) cognition in the sense that it needs to be considered as a dynamical process, in which aspects of action, perception, introspection, and social interaction are of crucial importance

Validating Kinematic Displays for the Perception of Musical Performance

Human gestures contain certain characteristics and meanings in communication and represent a link between intention and body. This paper describes a pilot study investigating the role of ancillary musical gestures in understanding musical meaning from the listener's standpoint. We conducted a perceptual experiment using motion-capture recordings of musicians. Participants were presented video recordings and reconstructed point-light displays of music performances. By asking them to rate certain musicrelated parameters we found that abstract motions of the point-light displays yielded similar ratings to those of the real recordings. This suggests that pure body motion seems to be sufficient to communicate certain musical impressions

Enhancing the Visualization of Percussion Gestures by Virtual Character Animation

International audienceA new interface for visualizing and analyzing percussion gestures is presented, proposing enhancements of existing motion capture analysis tools. This is achieved by offering a percussion gesture analysis protocol using motion capture. A virtual character dynamic model is then designed in order to take advantage of gesture characteristics, yielding to improve gesture analysis with visualization and interaction cues of different types

Formação e literatura : relatos sem fronteiras

O presente texto, resultado de uma pesquisa de caráter qualitativo-interpretativo, tem por objetivo contribuir para (re)pensar o papel do Ensino Superior na formação do professor de Língua Portuguesa, especificamente, na constituição do leitor literário, considerando a importância da experiência contínua e dinâmica na formação dos alunos de Letras – futuros mediadores de leitura literária em instituições de Educação Básica. Para tanto, se fez necessário compreender quais as razões que levam os alunos de Letras, em fase de conclusão de curso, no período de Estágio Supervisionado, a expressarem insegurança, medo e despreparo para desenvolver práticas pedagógicas de leitura literária. Como foco de investigação, buscou-se perceber como esses alunos se veem, como veem o curso de Letras e o conteúdo estudado na Universidade frente ao contexto profissional e de formação em que se encontram. Assim, foram ouvidos dez estudantes brasileiros da Universidade Federal da Bahia e cinco alunos portugueses da Universidade do Minho, Braga. A entrevista semiestruturada e o diário de campo foram os recursos utilizados para a coleta dos dados. Como aporte teórico, os estudos de Leahy-Dios e Menezes(2001), Dionísio (1990, 2004), Zilberman (1991), Todorov (2009), Perrone-Moisés (1998), Canário (2001), foram considerados. Os resultados desse estudo evidenciam a crise revelada pelos alunosprofessores, uma vez que, quando se encontram em período de Estágio Supervisionado, em práticas de ensino, na fase conclusiva da formação acadêmica para lecionar Língua Portuguesa, não conseguem estabelecer diálogo entre as teorias aprendidas nas aulas de literatura e a prática pedagógica requerida para a mediação e formação de novos leitores literários.CAPES, B

Digestibilidade do capim coast-cross determinada a pasto para éguas gestantes.

A fisiologia nutricional de eqüinos mantidos a pasto, em particular éguas gestantes, tem sido pouco estudada. Os dados existentes para estabelecer os requerimentos nutricionais dos animais e valor nutritivo das forrageiras normalmente utilizadas em condições tropicais são insuficientes para um adequado manejo da alimentação, o que motivou este estudo
