415 mothers were asked whether their children had specially beloved objects or not, its description and in what circumstances they would use the objects, and so on. 90 mothers answered that their children had some kind of “transitional objects” (Winnicott, 1953). Hayashi II's method was used in order to examine whether there was any difference between “primary and secondary transitional objects” (Stevenson, 1954). The results showed that “secondary transitional objects”. were used more as play objects than “primary transitional objects”. The second part of this study was to investigate whether children's possessing or not possessing the objects had relations to their mothers' attitude toward them. 43 mothers whose children possessed the objects and 97 mothers with children without objects were chosen and questioned on their attitude to their children. By ANOVA, it was shown that children's possessing or not the objects was related to their mothers' attitude toward them.
