概括
像运动指令和包装这样的新方法保留了来自不同年轻人的神经成像数据,使得可重复的脑行为关联研究成为可能. 这些方法通过保留因头部运动而经常被排除的参与者来改善样本代表性.
科学领域:
- 神经科学是一个神经科学.
- 神经成像是一种神经成像.
- 人口研究是指人口研究.
背景情况:
- 大规模的神经科学数据集能够对大脑行为关联进行可重现的效应大小估计.
- 严格的质量控制,特别是头部运动,往往不成比例地排除了少数群体中的个人.
- 这种排除限制了人口神经科学研究结果的概括性.
研究的目的:
- 在青少年大脑认知发育 (ABCD) 研究中,评估运动排序和运动排序+重新采样 (包装) 方法,以保存功能磁共振成像 (fMRI) 数据.
- 确定这些方法是否增强样本代表性,并保持可复制的大脑行为关联在不同的种族/民族群体.
- 评估这些方法对分析认知表现和心理病理学与功能连接相关的影响.
主要方法:
- 在ABCD研究 (N=5733) 的fMRI数据上使用了运动命令和包装技术.
- 使用功能连接性和认知/精神病理学措施之间的部分斯皮尔曼等级相关性 (Rs) 计算了大脑行为关联.
- 在所有分析中,根据参与者的性别和头部运动进行调整.
主要成果:
- 黑人和西班牙裔年轻人表现出更高的头部运动,并且被传统方法不成比例地排除在外.
- 运动订单和包装保留了超过99%的黑人和西班牙裔年轻人.
- 这两种方法都产生了跨种族/族群的可重现的大脑行为关联,即使运动水平不同.
结论:
- 运动排序和包装是改善人口神经科学中样本代表性的可行方法.
- 这些方法有助于在不同人群中测试大脑行为关联.
- 这些方法确保了可重现的效果大小,提高了不同组的研究结果的可靠性.

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

01:27Ethnic Identity within a Larger Culture

Adolescents from ethnic minority backgrounds face a multifaceted journey in forming their identities, shaped by the intersections of cultural expectations and personal exploration. For these adolescents, identity formation involves not only typical developmental challenges but also navigating the perceptions and attitudes of the majority culture. As they grow, adolescents in ethnic minority groups often become increasingly aware of stereotypes, social biases, and discrimination, all of which...

25
Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
