예측적 응시 패러다임에서 살펴본 영아의 암묵적 마음이론의 발달적 차이.

Objectives: This study examined the developmental differences of implicit theory of mind in infants aged 12 to 24 months according to two types of tasks within the anticipatory looking paradigm, as well as the interaction between age group and type of task. Methods: In all, 69 infants participated in this study aged 12, 18, and 24 months. Two types of implicit false-belief tasks using an anticipatory looking paradigm were administered to all the infants for about 4 minutes 20 seconds. While all of the infants watched two types of computerized video clips (FB1, FB2) through the computer screen, an eye-tracker (TobiiX120) recorded the traces of anticipatory looking of infants. The anticipatory looking of infants in test trials was then analyzed. Results: Results showed that the differences between the 12-month-olds and the other age groups (18-month-olds, 24-month-olds) were significant, but even some of the 12-month-olds showed evidence of an implicit theory of mind. The level of implicit theory of mind of 18-month infants did not significantly differ from that of 24-month infants. In addition, a difference by type of implicit falsebelief task was significant. Infants showed a higher level of implicit theory of mind in Task1 (FB1) than in Task2 (FB2). However, the interaction effect between age and type of task was not significant. Conclusion: The findings of this study hold implications for the development of implicit theory of mind early in life, and indicate the validity of the anticipatory looking paradigm with two types of tasks. Several limitations and suggestions for future study are also presented. [ABSTRACT FROM AUTHOR]
