概括
患有注意力缺陷/多动障碍 (ADHD) 的儿童表现出多样化的延迟厌恶特征,而不仅仅是更的折扣. 有些人表现出浅或零折扣,与大脑连接的改变有关,这表明了更好的诊断和治疗的维度方法.
科学领域:
- 神经科学是一个神经科学.
- 心理学 心理学 心理学
- 儿童精神病学 儿童精神病学
背景情况:
- 注意缺陷/多动障碍 (ADHD) 的认知异质性得到了很好的研究,但动机变异性,特别是延迟厌恶,不太了解.
- 现有的研究通常假定在ADHD中延迟折扣的均增加,可能会忽视微妙的动机缺陷.
研究的目的:
- 在被诊断患有多动症的儿童样本中识别同质的延迟不良情况.
- 调查与这些独特的延迟厌恶特征相关的动机缺陷.
- 通过功能连接分析,探索这些特征的神经生物学基础.
主要方法:
- 集群分析是在43名ADHD儿童和47名对照儿童的体验性延迟折扣任务上进行的.
- 外部验证包括家长/教师的临床评级和前端对象 (FPN) 和默认模式 (DMN) 网络的静止状态功能连接 (rsFC) 通过fNIRS.
- 一个由五个配置文件组成的解决方案出现了,根据参与者在延迟时间内的奖励值来对参与者进行分类.
主要成果:

Attention-Deficit/Hyperactivity Disorder
34
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....

Autism Spectrum Disorder
50
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Oppositional Defiant Disorder
21
A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

Conduct Disorder
23
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;...

Modeling in Therapy
37
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Behavior Modification
113
Behavioral approaches have often been criticized for ignoring mental processes and focusing solely on observable behavior. However, these approaches provide an optimistic perspective for individuals seeking to change their behaviors. Rather than concentrating on intrinsic personality traits, behavioral approaches suggest that even longstanding habits can be modified by changing the reward contingencies that maintain them.
