Memory Monitoring and Control in Japanese and German Preschoolers.

Prior studies explored the early development of memory monitoring and control. However, little work has examined cross-cultural similarities and differences in metacognitive development in early childhood. In the present research, we investigated a total of 100 Japanese and German preschool-aged children's memory monitoring and control in a visual perception task. After seeing picture items, some of which were repeated, children were presented with picture pairs, one of which had been presented earlier and the other was a novel item. They then were asked to identify the previously presented picture. Children were also asked to evaluate their confidence about their selection, and to sort the responses to be used for being awarded with a prize at the end of the test. Both groups similarly expressed more confidence in the accurately remembered items than in the inaccurately remembered items, and their sorting decision was based on their subjective confidence. Japanese children's sorting more closely corresponded to memory accuracy than German children's sorting, however. These findings were further confirmed by a hierarchical Bayesian estimation of metacognitive efficiency. The present findings therefore suggest that early memory monitoring and control have both culturally similar and diverse aspects. The findings are discussed in light of broader sociocultural influences on metacognition.

Metacognition and mindreading in young children: A cross-cultural study.

Prior studies document cross cultural variation in the developmental onset of mindreading. In particular, Japanese children are reported to pass a standard false belief task later than children from Western countries. By contrast, we know little about cross-cultural variation in young children's metacognitive abilities. Moreover, one prominent theoretical discussion in developmental psychology focuses on the relation between metacognition and mindreading. Here we investigated the relation between mindreading and metacognition (both implicit and explicit) by testing 4-year-old Japanese and German children. We found no difference in metacognition between the two cultural groups. By contrast, Japanese children showed lower performance than German children replicating cultural differences in mindreading. Finally, metacognition and mindreading were not related in either group. We discuss the findings in light of the existing theoretical accounts of the relation between metacognition and mindreading.
