title: Differences in episodic memory between four- and five-year-olds: false information versus real experiences.
abstract: It is assumed that personal episodes from any age less than about four years can rarely be recalled (infantile amnesia) because episodic memory is not well developed until this age. To investigate this, experiments were conducted with 30 4- and 30 5-yr.-olds. Experiments first examined whether the children could report parent-child games in a sports festival two days after the festival. The results indicated that 4-yr.-olds could not report the episodic contents of the games properly even though they reported the results of the ball matches as well as the 5-yr.-olds. Seven days after that report, the subject was told twice by the experimenter about realistic or unrealistic events as if these were their own experiences. The subject was again required to report the events seven days after receiving information. The results showed that 4-yr.-olds tended to mistake the information provided by the experimenter for their own real experiences. These results indicate that there may be a critical difference of episodic memory between 4- and 5-yr.-olds. Episodic memory was not well developed yet in 4-yr.-olds.
