Core Viewpoint - The article discusses the phenomenon of procrastination in children, particularly adolescents, and explores its underlying causes and potential solutions from psychological and neurological perspectives [4][5][6]. Group 1: Types of Procrastination - Procrastination can manifest in three main forms: preparation procrastination, where children engage in activities like organizing their study space instead of doing homework; substitution procrastination, where they distract themselves with unrelated tasks; and distraction procrastination, where they are easily sidetracked by digital devices [1][2][3]. Group 2: Neurological Development - The article highlights that the development of the prefrontal cortex, responsible for rational decision-making, lags behind the limbic system, which governs immediate gratification, making it harder for adolescents to resist distractions and manage their time effectively [4]. Group 3: Psychological Mechanisms - Procrastination in children can be a form of passive aggression against perceived over-control by parents, where they assert their autonomy through delaying tasks [6]. - Emotional needs, such as the desire for parental attention, can also drive procrastination, as children may delay work to prolong time spent with parents [7]. - Perfectionism can lead to procrastination, as children may fear making mistakes and thus avoid starting tasks altogether [8]. Group 4: Recommendations for Parents - Parents are advised to provide children with limited choices to foster a sense of autonomy, rather than imposing strict commands [6]. - It is suggested that parents adjust their schedules to spend quality time with their children, promoting emotional connections and reducing procrastination [7]. - Encouraging a growth mindset by accepting imperfections and celebrating progress rather than perfection can help alleviate the pressures that lead to procrastination [8].

欧洲央行行长拉加德26日在德国柏林参加一场活动时指出，当前的国际秩序正在受到根本性的动摇，多 边合作正在被零和思维与权力博弈所取代。开放正让位于保护主义。拉加德说，欧洲经济深度融入全球 贸易体系，出口占欧洲经济增加值的近五分之一，并支撑着3000万个就业岗位。国际秩序中任何导致世 界贸易下降或经济集团分裂的变化，都将对欧洲经济造成不利影响。但只要采取正确的政策应对，形势 变化也可能为欧元在未来的国际舞台上发挥更大作用提供可能性。拉加德说，美元的主导地位也存在不 确定性。近年来，美元在全球外汇储备中的占比不断下降，目前的占比是1994年以来的最低水平。拉加 德表示，欧元如今是第二大全球货币，占全球外汇储备的20%左右。增强欧元的国际地位将促使更多贸 易以欧元计价，从而令欧洲免受不稳定的资本流动的影响。为提升欧元的全球地位，欧洲需要坚定不移 地致力于开放贸易，巩固经济基础以促进资本市场发展，以及捍卫法治和政治团结。(新华社) ...
