Laboratory instruments as a means of contact for the operant. Los Instrumentos de laboratorio como medio de contacto de la operante.

Abstract

The experimental practices are those actions involved in the interaction of the scientific with a segment of reality previously definite. During this interaction, the investigator frequently uses different instruments to doing possible the investigative function. A microscope, for sample allows that the biologist to interact with the different properties of the cell, and although instruments are only a medium for the behaviour investigative, its use affects the conception of the phenomena under study or such conceptions are affected by these, since the instruments specify the circumstances of occurrence of the events. In this work are analysed the development of the relations given between instruments of investigation of the laboratory and the nature of the psychological phenomena, expecting to delimit more accurately the analytical categories of the psychological theory.
