Abstract
Ruuth, E. & Smith, G. J. W. Projected afterimages and cognitive maturity. Scand. J. Psychol., 1969, 10, 209–214—The hypothesis that projected afterimages will remain size‐constant if they are not isolated by the observer as subjective phenomena is tested in a group of 20 children classified with respect to cognitive maturity. The less mature children, still mainly in the preoperational stage, are more resistant to size‐increase with increasing projection distance and also report more positive hues. Tney apparently confuse their afterimages with real objects and thus fail to objectivize.Keywords
