This study aimed to investigate the mechanism of the development of level 2 visual perspective taking (VPT2) in early school-aged children. The results showed that working memory capacity (WMC), mental rotation (MR), and VPT2 ability developed progressively from 6 to 8 years old. The ability of VPT2 was significantly correlated with WMC and MR, and the changes in WMC and MR partially mediated the development of VPT2.
The present study aimed to investigate the mechanism underlying the development of level 2 visual perspective taking (VPT2). Specifically, we examined the role of working memory capacity (WMC) and mental rotation (MR) in the developmental change of VPT2 among early school-aged children. Children aged between 6 and 8 years (N = 150) completed measures to assess WMC, MR, and VPT2. Results showed that WMC, the ability of MR, and VPT2 developed progressively from 6 to 8 years old. The ability of VPT2 was significantly correlated with WMC and MR, even when age was statistically controlled for. Mediation analyses further revealed that both age-related changes in WMC and MR partially mediated the development of VPT2. Furthermore, age-related development in MR mediated the relationship between changes of WMC and VPT2. Our findings suggest the importance of WMC and MR in the early development of VPT2 and provide preliminary support for the developmental cascade hypothesis. That is, as children grow up, their WMC increases, leading to better capability of MR, which in turn results in the improvement of VPT2.
