Executive function (EF) skills are considered to be important factors for the development of children’s school readiness and academic achievement. These skills may be developed in the home environment. The relation between home environment and the development of children’s EF has been widely discussed in the literature on early childhood education. It is also important to investigate the relation between EF-specific activities at home and the development of children’s EF skills. The Home EF Environment (HEFE) scale was recently developed and it was found that the parents’ EF-specific activities were positively correlated to the children’s EF. However, the items of the scale didn’t reflect all EF-specific activities at home and the scale cannot be administrated to Korean children without modification since the home environment varies in different cultures. For this reason, in the present study, we detailed the items of HEFE scale and analyzed the association between the parent-reported HEFE scale and EF skills of children with a sample of 146 preschool children and one of their parents in Pyongyang, the Democratic People’s Republic of Korea. For the sample, the mean age of children ranged from 34 to 57 months (M = 46.66, SD = 6.99), and 50.7% were male. On the basis of a correlational matrix, we found that the HEFE scale was positively correlated to the inhibitory control and working memory of children, but not to cognitive flexibility. We also found that the Home Learning Environment (HLE) was significantly and positively related to all three domains of children’s EF. In addition, some of the EF-specific activities (block play, memory game, concentration game and jogging) were significantly correlated to the HLE. The potential importance of the HLE and EF-specific activities at home are addressed in the discussion.

执行功能（EF）技能被认为是儿童入学准备和学习成绩发展的重要因素。这些技能可以在家庭环境中发展。关于儿童早期教育的文献已经广泛讨论了家庭环境与儿童EF的发展之间的关系。研究在家中进行的EF活动与儿童EF功能发展之间的关系也很重要。最近开发了家庭EF环境（HEFE）量表，发现父母的EF特定活动与孩子的EF正相关。然而，量表的项目并不能反映出家庭中所有与EF相关的活动，而且由于家庭环境因文化的不同而存在差异，因此无法对韩国儿童进行量表的修改。因此，在本研究中，我们详细介绍了HEFE量表的项目，并分析了平壤，朝鲜民主主义人民共和国的146名学龄前儿童及其父母中，父母报告的HEFE量表与儿童的EF技能之间的关联。大韩民国。对于样本，儿童的平均年龄为34到57个月（M = 46.66，SD = 6.99），其中50.7％为男性。在相关矩阵的基础上，我们发现HEFE量表与儿童的抑制性控制和工作记忆呈正相关，但与认知柔韧性没有正相关。我们还发现，家庭学习环境（HLE）与儿童EF的所有三个领域都显着正相关。此外，某些EF特定活动（积木游戏，记忆游戏，注意力游戏和慢跑）与HLE显着相关。讨论中讨论了在家中进行HLE和EF特定活动的潜在重要性。
