Abstract

The Face Stimulus Assessment is an efficient projective drawing test developed by Betts. This paper categorizes scales which Betts suggested into the following five groups: accuracy of painting, color fit, perception of shape, precision of drawing, and space usage. In this paper, a computer algorithm which objectively evaluates these five scales is suggested. The proposed algorithm defines the areas of the lip, eyes, hair, etc. which take on significant roles in the evaluation of the FSA and based on these factors, it calculates the grade of each scale through the main color and color ratio. The consistency of evaluations between the computer algorithm and the art therapist is measured by the Quadratic Weighted Kappa. By providing objectivity and consistency, the computer algorithm is expected to solve the problem of uncertainty found in art therapists' evaluations of projective drawing tests caused by their subjective judgment, experience, and intuition.

2003년 Betts는 효율적인 투사검사 기법의 일환으로 FSA(얼굴자극검사: Face Stimulus Assessment)를 개발하였다. 이 논문에서는 Betts가 제안한 FSA 척도들을 색칠의 정확도, 색상의 적합도, 형상의 인식도, 묘사의 정밀도, 공간의 활용도의 다섯 가지로 분류하고 이를 객관적으로 평가하는 컴퓨터 알고리즘을 개발한다. 본 알고리즘은 눈, 입 술, 머리카락 등의 FSA 평가에 주요한 요인의 영역을 설정하고, 대표색 및 색의 비율을 통해 각 척도들의 등급을 산출한다. 그리고 이차 가중 Kappa 값을 통해 미술치료 전문가의 평가와 컴퓨터 알고리즘의 평가 간의 일관성을 보이고, 이를 통해 본 알고리즘의 적합성을 검증한다. 이 논문은 FSA를 평가함에 있어 미술치료사의 주관이나 경험 또는 직관에 따른 불확실성을 극복하고 객관성과 일관성을 제공하여 그림을 통한 투사검사의 신뢰성을 높일 수 있을 것으로 기대된다.
