概括
基于对象的注意力通过突出的分心因素影响着注意力捕捉. 当目标和分心器共享一个对象时,观察到的对象内部好处,只有当分心器吸引注意力时,才会发生,支持扩散对象注意力理论.
科学领域:
- 认知心理学 认知心理学
- 神经科学是一个神经科学.
- 视觉注意力 视觉注意力
背景情况:
- 突出的分心因素会自动吸引人们的注意力.
- 基于对象的注意力在调节这种捕获中的作用尚未完全理解.
研究的目的:
- 为了研究基于对象的注意力如何影响通过突出的分心因素来捕捉注意力.
- 为了确定是否将项目分组成感知对象会影响注意力捕获和随后的目标处理.
主要方法:
- 使用修改后的额外单元范式的四个实验,根据近距离分组成两个对象的项目.
- 操纵目标和单元分心器是否属于相同或不同的对象.
- 行为测量 (反应时间) 和电生理测量 (事件相关潜力 - ERP),包括N2pc和PD组件.
主要成果:
- 一个单元分心器的注意力捕捉发生在它是一个独特颜色的物品和目标是一个独特形状的物品时.
- 只有当单元分心器引起注意时,才观察到对象内部的好处 (当目标和分心器在同一对象中时,反应时间更短).

Attention-Deficit/Hyperactivity Disorder
834
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....

Spreading of Chromatin Modifications
9.4K
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

Self-Evaluation: Self-Enhancement and Self-Verification
5.8K
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...

Potential Due to a Polarized Object
752
A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...

Potential Due to a Magnetized Object
776
Magnetic dipoles in magnetic materials are aligned when placed under an external magnetic field. For paramagnets and ferromagnets, dipole alignment occurs in the direction of the magnetic field. However, the dipoles align opposite to the field in the case of diamagnets. This state of magnetic polarization due to the external field is called magnetization. Magnetization is defined as the dipole moment per unit volume. It plays a similar role to polarization in electrostatics.

Moment of Inertia of Compound Objects
7.5K
The moment of inertia is a quantitative measure of the rotational inertia of an object. It is defined as the sum of the products obtained by multiplying the mass of each particle of matter in a given body by the square of its distance from the axis. The total moment of inertia for compound objects can be found by determining and adding the moment of inertia of individual components together.
