- 发展心理学 发展心理学
- 儿科健康 儿科健康
背景情况:
- 饮食质量与老年儿童的认知健康有关.
- 这种关系在西班牙裔学龄前儿童中没有得到充分研究,这是一个脆弱的群体.
- 社会经济和文化因素可能会影响这一群体的饮食和认知发展.
研究的目的:
- 调查学前儿童饮食质量与儿童后期执行功能 (EFs) 之间的纵向关联.
- 检查饮食质量的特定组成部分及其对不同类型EFS的影响.
主要方法:
- 一项涉及185名西班牙裔母婴二合体的纵向研究的二次分析.
- 使用健康饮食指数 (HEI) -2010评估的饮食质量,来自3个24小时的召回.
- 执行功能 (冷和热) 用实验室任务在基线和18个月测量.
主要成果:
- 脂肪酸的HEI-2010组件得分与更好的寒冷EF相关 (b = -0.13,P = 0.04).
- 海鲜和植物蛋白质的HEI-2010组件得分与更好的热 EFs相关 (b = 0.09,P = 0.05).

Environmental Influences on Intelligence
275
Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children...

Information Processing Approach
33
The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

Longitudinal Studies
156
Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Longitudinal Research
11.9K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Attention-Deficit/Hyperactivity Disorder
55
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Biological Influences on Intelligence
89
Intelligence is often thought to be linked to brain size, but the relationship is more complex than that. While brain size does correlate modestly with some abilities, like verbal skills, the connection is weaker for others, such as spatial reasoning. Other factors, like brain structure, also play crucial roles. For instance, despite Einstein's smaller-than-average brain, his parietal cortex, which is involved in spatial reasoning, was 15% wider, suggesting that neural density might matter...
