Resumo
Estudos demonstram que a música e o Treino Musical (TM) atuam em diversas áreas do desenvolvimento humano: cognição, linguagem, socialização e raciocínio lógico-matemático. Há evidências de que o Treino Musical propicia ganhos quanto à memória operacional e à numerosidade de crianças escolares. Supõe-se que o TM poderia contribuir para a estimulação destas habilidades cognitivas em crianças pré-escolares. Este estudo prospectivo investigou os efeitos do TM sobre as habilidades de numerosidade e memória operacional em 57 pré-escolares com desenvolvimento típico e com idade de cinco anos em uma cidade do interior paulista. A amostra foi dividida em dois grupos, a saber: GE (Grupo Experimental; n=25) que participou de oito sessões do TM e o GC (Grupo Controle; n=32) que não recebeu estimulação musical, ambos balanceados quanto ao sexo. Todos os participantes foram avaliados em duas etapas por meio de instrumentos para os seguintes domínios: Raciocínio Abstrato (MPC – Escala Especial); Cognição Numérica (Zareki-K – Bateria Neuropsicológica para Avaliação do Tratamento dos Números e do Cálculo para Crianças Pré-escolares); e Memória Operacional (AWMA-Short form – Avaliação Automatizada da Memória Operacional-Versão reduzida). Os resultados mostraram que o TM produziu modificações relacionadas ao processamento numérico, senso numérico, bem como em memória operacional verbal.
Studies demonstrate that music and Music Training (MT) act in various human development areas: cognition, language, socialization, and logical-mathematical thinking. Evidences show that Music Training affords gains in both working memory and numeracy of school children. It is supposed that MT may contribute to stimulation of these cognitive abilities in preschoolers. This prospective paper investigated the MT effects on numeracy and working memory in 57 5-year-old preschoolers with typical development from a city in the countryside of Sao Paolo state in Brazil. The sample was divided into two groups: EG (Experimental Group; n=25), which took part of eight TM sessions, and CG (Control Group), which had no musical stimulation; both groups are gender-balanced. All participants were assessed in two stages through instruments for the following domains: Abstract Reasoning (CPM – Raven’s Coloured Progressive Matrices); Numerical Cognition (Zareki-K – Neuropsychological test battery for number processing and calculation in primary school and kindergarten children, in English) and Working Memory (AWMA–Short form – Automated Working Memory Assessment – Short form). Results show that MT produced modifications related to number processing, number sense and verbal working memory.
