Musicians' working memory for tones, words, and pseudowords

Studies investigating factors that influence tone recognition generally use recognition tests, whereas the majority of the studies on verbal material use self-generated responses in the form of serial recall tests. In the present study we intended to investigate whether tonal and verbal materials share the same cognitive mechanisms, by presenting an experimental instrument that evaluates short-term and working memories for tones, using self-generated sung responses that may be compared to verbal tests. This paradigm was designed according to the same structure of the forward and backward digit span tests, but using digits, pseudowords, and tones as stimuli. The profile of amateur singers and professional singers in these tests was compared in forward and backward digit, pseudoword, tone, and contour spans. In addition, an absolute pitch experimental group was included, in order to observe the possible use of verbal labels in tone memorization tasks. In general, we observed that musical schooling has a slight positive influence on the recall of tones, as opposed to verbal material, which is not influenced by musical schooling. Furthermore, the ability to reproduce melodic contours (up and down patterns) is generally higher than the ability to reproduce exact tone sequences. However, backward spans were lower than forward spans for all stimuli (digits, pseudowords, tones, contour). Curiously, backward spans were disproportionately lower for tones than for verbal material-that is, the requirement to recall sequences in backward rather than forward order seems to differentially affect tonal stimuli. This difference does not vary according to musical expertise.

Contribuição para a formação de Psicólogos: análise de artigos de Carolina Bori publicados até 1962

A Psicologia, no Brasil, foi reconhecida legalmente no ano 1962. Contudo, antes desse ano, diversos profissionais já atuavam na área. Carolina Martuscelli Bori tem sido considerada um desses profissionais, e, dentre as contribuições que deu, sua luta para melhorar a formação profissional é uma das mais citadas. Com este trabalho, buscou-se conhecer sua contribuição a partir de artigos que Bori publicou até o ano 1962. A partir de uma busca feita nas revistas Ciência e Cultura, Boletim de Psicologia e Jornal Brasileiro de Psicologia, e no seu currículo Lattes, pela busca na biblioteca da Universidade de São Paulo e em referências de artigos escritos sobre a própria Carolina Bori, 19 artigos foram localizados, dos quais oito foram publicados até 1962. A análise feita permite afirmar que a obra de Carolina Bori apresenta discussões que podem auxiliar na elaboração e no direcionamento de várias questões éticas e acadêmicas atuais, como: a pesquisa experimental em cursos de graduação, a metodologia científica, o desenvolvimento científico e a produção do conhecimento.

Conceptual and Experimental Directions for Analyzing Superstition in the Behavioral Analysis of Culture

This paper examines the notions of illusions and beliefs, discussing some advantages offered by the study of these phenomena based on the concepts of superstitious behavior, superstition and superstitious rules. Among these advantages, the study highlights the possibility of researching these relationships in different levels of analysis, not only at the individual level, focusing on cultural level, this paper presents Cultural Materialism as an anthropological proposal for the consideration of these phenomena on the cultural level and based on adaptive principles, besides it discusses the experimental analysis of cultural practices and points Out how they can help to understand how people in groups behave such as they are being effective in the control of the surrounding environment (when, sometimes, in fact, they are not). The paper offers an integrative proposal which makes easier behavior analysts' dialogue with social psychologists and offers some routes from cultural analysis of illusions and beliefs.

A critical analysis on "Active Learning" in the light of Cultural-Historical Activity Theory (CHAT): Implications to Physics Education and to experimental activities as a particular case.

This is a research paper in which we discuss “active learning” in the light of Cultural-Historical Activity Theory (CHAT), a powerful framework to analyze human activity, including teaching and learning process and the relations between education and wider human dimensions as politics, development, emancipation etc. This framework has its origin in Vygotsky's works in the psychology, supported by a Marxist perspective, but nowadays is a interdisciplinary field encompassing History, Anthropology, Psychology, Education for example.
