ABSTRACT

O presente estudo buscou identifi car e analisar a percepção de instrutores de esporte de aventura acerca de procedimentos necessários à condução das modalidades no estado de Minas Gerais. Por meio de uma pesquisa qualitativa, foram identifi cados instrutores com três níveis e áreas de formação profissional: ensino médio, graduados em Educação Física e em outras áreas do conhecimento. A experiência prática como praticante foi apontada como pré-requisito para atuação como instrutor. Quanto aos possíveis impactos ambientais causados pela prática de esporte de aventura, prevalece uma visão positiva por parte dos instrutores, o que, nem sempre, condiz com a realidade. A percepção acerca dos procedimentos necessários à segurança do praticante ganhou relevo na percepção dos instrutores....(AU)


The present study sought to identify and analyze the perception of adventure sports instructors about procedures required to conduct the modalities in the state of Minas Gerais. Through a qualitative research, instructors with three levels and areas of professional training were identifi ed: high school, graduates in Physical Education and other areas of knowledge. Practical experience as a practitioner was indicated as a prerequisite for acting as an instructor. Prevails a positive vision about possible environmental impacts due to the practice of adventure sports, which, not always, is in keeping with reality. The perception of the procedures necessary to the practitioner's safety has gained prominence in the insights of the instructors....(AU)

ABSTRACT

León, Abad y Rosas, (2010b) demostraron que la atención al contexto se pierde conforme aumenta el entrenamiento. Así, a medida que aumenta el entrenamiento se observa una mayor generalización entre contextos distintos al de entrenamiento al perderse la atención. El objetivo del presente estudio fue poner a prueba ésta idea empleando una tarea instrumental en humanos con distintos valores del contexto (color). La tarea consistió en un juego de ordenador en el que se emitían distintas respuestas bajo un programa IV2s, en presencia de distintos estímulos discriminativos. En el Experimento 1 se entrenaron dos grupos con 3 y 8 ensayos, posteriormente se realizó un ensayo de prueba en el contexto de entrenamiento (amarillo) y en un contexto diferente (rojo). Los resultados demostraron una disminución de la ejecución con el cambio de contexto. En el Experimento 2 se entrenaron dos grupos de manera similar al Experimento 1, empleando un contexto naranja. Durante la prueba se presentaron degradaciones del color del contexto de entrenamiento con valores intermedios hacia el color amarillo y rojo. Los resultados sugieren que la atención al contexto de entrenamiento está modulada diferencialmente por la cantidad de entrenamiento en la tarea.


León, Abad and Rosas (2010b) shown that as the training increased attention to the context decreased. Thus, increasing the training might produce a greater generalization between different contexts. The main goal of the present experiments was to test this idea modifying different values of the context (i. e., colors) using an instrumental task with humans. The task was a videogame in which participants performed under an IV2s schedule in presence of different discriminative stimuli to obtain reinforces. In Experiment 1 two groups were trained with 3 or 8 trials, then a test trial was conducted in the training context (i. e., yellow) or in a different context (i. e., red). Results shown that changed the context produced a loss of performance. In Experiment 2 two groups were trained with similar parameters used in Experiment 1 but using an orange context. Test was conducted with different values of the orange (i. e., training context) toward yellow and red. The pattern of the data suggests that experience with the task modulates in different ways attention to contextual cues.
