A STUDY ON STRUCTURAL MODELS OF PSYCHOLOGICAL EVALUATION : A proposal of a model with 2 turning points on response continuum and the example of its application

Abstract

A new model with 2 turning points on response continuum is introduced to express a structure of psychological evaluation, and the example of an application of this model is reported. The relation between physical stimlus and human judgement is roughly classified into two patterns. One type has 1 turning point in judgement according to increase of stimulus, and the other has 2 turning points in it. The former is able to be analyzed by the usual psychological model, but the latter has not been discussed in the architectural field. Therefore, a new model that explains the latter type is introduced corresponding to judgement on the scale of "evaluation" extracted from semantic differential technique. Secondarily, the concept of this model is mentioned and the solution by numerically calculation is explained. In the latter half of this report, the experiment is stated as the application of this model about the best illuminance on sleeping and resting. Experiments was made under the following conditions ; Date : Dec. 1-3, 1983. Place : in the experimental room at Building Research Institute, Ministry of Construction. Experimental conditions : the illuminance on the face of subjects is able to be controlled from 0 lx to 1 900 lx. Subjects : 9 people. Scale of rating : "good-bad" bipolar scale, 6 categories. Method : method of adjustment for 2 settings and method of constant for 4 settings. After the application of this model to the results of this experiment, the best illuminance is calculated and Weber-Fechner's theory was led between the illuminance and the human judgement under the condition of this experiment.
