From Home to the Classroom: An Investigation of the Relation between Environmental Chaos and Children’s Executive Function
Environmental chaos, characterized by disorganization, inconsistent routines, and elevated noise levels, impairs children's executive function (EF), a crucial cognitive process for academic and lifelong success (Andrews et al., 2020; Gao et al., 2023). While extensive research exists on household chaos effects, limited studies examine classroom chaos impact on EF, despite children spending increasing time in educational settings (Hong Kong Education Bureau, 2021). Even fewer studies investigate the combined effects of both environments. The bioecological model suggests that home and school function as interconnected microsystems, where positive experiences in one setting may offset negative experiences in another (Bronfenbrenner & Morris, 2006; Berry et al., 2016). This study aims to: 1) assess the relative contributions of household and classroom chaos to children's EF; and 2) explore whether well-structured classrooms can mitigate household chaos effects. Using a longitudinal design with multilevel analyses, the findings will provide insights particularly relevant to fast-paced metropolitan areas like Hong Kong and offer actionable information for improving parent-child and teacher-child interactions in chaotic environments.

Orthographic Executive Functions: A Missing Component for Understanding Early Writing Ability in Chinese?
Chinese is one of the most challenging writing systems to learn due to its complex orthographic characteristics. Orthographic knowledge – the understanding of how orthographic units are structurally combined to form characters – is thus an essential foundation for early writing development. However, whether orthographic knowledge alone is sufficient for young children to handle the complexity of Chinese characters remains largely unknown. In this study, a novel concept – orthographic executive functions (EF) – is proposed to represent a crucial yet overlooked cognitive aspect of orthographic competence. We propose that successful young writers not only need to be equipped with orthographic knowledge, but they also need to exercise EF skills for coordinating such a complex system of orthographic knowledge during the process of writing. To test our hypothesis, we will develop tasks to assess four potential types of orthographic EF skills – orthographic working memory, orthographic inhibition control, orthographic cognitive flexibility, and orthographic planning – of 160 kindergarten children aged 4.5 to 6 years. If these EF skills are found to have a unique and significant contribution to children’s word writing ability after controlling for a range of writing-related factors, our findings will provide an important contribution to the theoretical understanding of Chinese early writing development.Apart from examining the importance of orthographic EF as a unique predictor of word writing, our study also aims to examine how orthographic EF may be related to the ability to copy characters, which is traditionally considered as a necessary pre-requisite for word writing. In this study, a cross-lagged autoregressive model is proposed to systematically examine the development of orthographic knowledge, orthographic EF, and copying ability in relation to each other longitudinally from K2 to K3. Cross-lagged panel analysis will be conducted to clarify whether copying ability indeed has a causal role in facilitating the orthographic components of writing as traditionally assumed. Ultimately, the contribution of the interaction between orthographic EF skills and copying ability to word writing will be studied.
