Abstract: The Wartegg Zeichen Test (WZT) is a method of personality evaluation developed by the psychologist Ehrig Wartegg. Three new scoring categories for the WZT consist of Evocative Character, Form Quality, and Affective Quality. In this paper, we present the object detection model in scoring the Affective Quality of WZT. Our works consist of two main parts: 1) using the YOLO (You Only Look Once) model to detect the hand-drawn square boxes from the WZT form, and 2) using YOLO to detect the object in the hand-drawn square box. In the experiments, YOLOv3 achieved 88.94% of mAP for hand-drawn square box detection and 46.90% of mAP for hand-drawn object detection.
