Estimação de magnitude de distância entre pares e tríades de pontos: um estudo exploratório

Abstract

The aim of this research was to study a spatial cognition involving great distances, utilizing the psichophsic method of Estimation of Magnitude. Twenty-three subjects were randomly distributed into two groups and submitted to a counterbalanced designo. All subjects were asked to estimate routes (distances between Brazilians cities). Where the number of points given among the routes would vary. We decided to define those experimental conditions into two categories: E-2 (estimations of routes having two cities) and E-3 (estimations of routes having three cities). Power functions were adjusted to all estimations. The result showed that there was a tendecy for more accurate estimations when the route to be estimated had three points. The exponents no found were lesser then 1.0 indicating an underestimation of the judgements.
