| Description | The Perceptual Closure and Design Scales were developed by Irving A. Taylor (1960) to assess perceptual reactions in individuals with opposing social attitudes, ranging from extreme conservatism to extreme liberalism. The study used incomplete visual representations, such as a house and a boy, composed of lines with small gaps. Participants were instructed to complete the figures by reproducing them as accurately as possible. The study aimed to explore completion tendencies under closure conditions, where an interrupted line is perceived as a single, cohesive shape. Results showed a 17% underestimation of the gap sizes, with the boy scale displaying a greater completion tendency compared to the house scale. The scales demonstrated strong internal consistency with reliability coefficients of .85 for the house scale and .90 for the boy scale, and a correlation of .62 (corrected to .71) between the two scales. The combined scores showed a significant curvilinear relationship for consistent social attitude samples. |
