Abstract
A new approach to concept attainment was proposed, in which continuous values on coordinates on a graphic display screen was used for the definition of concepts. It is contrasted with Brunner's or Hovland's experiments of concept attainment, in which the concept were defined by the dimensions on nominal or ordinal scales. In Experiment I, dimensions which prescribe the concept were constructed by scales of continuous values, the values of coordinates on a plane surface. Based on the results of Experiment I, a model of concept attainment strategy was presented by using a function. Regarding this function as a concept to be attained, another experiment of concept attainment, Experiment II, has been attempted. As a result, learning processes in these concept attainments were obtained. These experiments are throughly automated and controlled by computer (graphic display system).
