概括

问题性的智能手机使用与更大的右侧核聚集体 (NAcc) 体积有关,这预测了夜间屏幕时间,并与注意力缺陷有关. 这表明奖励系统的变化是过度数字参与的基础.

科学领域:

神经科学是一个神经科学.
精神病学是一个精神病学.
数字健康数字健康

背景情况:

问题性智能手机使用 (PSU) 的特点是过度参与,影响日常功能.
PSU与注意力控制缺陷和改变奖励处理有关.
作为奖励系统的一部分,核 (NAcc) 可能在难以脱离数字内容方面发挥作用.

研究的目的:

在有问题的智能手机使用 (PSU) 个体中,研究核 (NAcc) 体积,注意力切换和夜间屏幕时间之间的关系.
探索过度使用智能手机的神经生物学基础及其对认知功能的影响.

主要方法:

53名被诊断患有PSU的参与者 (≥13岁) 接受了心理评估,MRI扫描和智能手机记录.
用自闭症谱系系数子量表来评估注意力切换.
夜间屏幕时间 (00:00-06:00) 被客观地测量;NAcc体积被正常化为灰质体积.

主要成果:

注意力转换的困难与更大的右NAcc体积和增加的夜间屏幕时间相关.
正确的NAcc体积与夜间屏幕时间正相关.
回归分析表明,正确的NAcc体积预测了夜间屏幕时间,独立于注意力切换.

结论:

较大的右侧NAcc体积是PSU患者长时间夜间使用智能手机的独立预测指标.
在NAcc的结构变化与受损的注意力切换有关,并可能是脱离数字内容的困难的基础.
结合神经生物学,认知和行为数据,为了解PSU提供了一个全面的框架.

Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

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....

High-Level and Low-Level Awareness

High-Level and Low-Level Awareness

Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

Schemas

Schemas

A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.
