概括

稀缺心态会损害选择性注意力,使得更难过干扰. 这种通过大脑活动测量的认知效应表明,人们对相关信息的关注能力降低了.

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.
社会心理学社会心理学

背景情况:

选择性注意力对于认知控制至关重要,使得人们能够专注于相关的刺激,并忽略分心.
稀缺心态对选择性注意力及其神经机制的影响需要进一步研究.
了解这种关系对专业和个人运作都有影响.

研究的目的:

实验性地研究稀缺心态对选择性注意力的影响.
使用脑电图 (EEG) 探索潜在的神经机制.

主要方法:

参与者被分配到稀缺或中性条件.
使用视觉搜索任务,需要在分散注意力的环境中识别目标.
使用EEG记录大脑活动,专注于与事件相关的潜能,如N2pc,Pd和Nt.

主要成果:

稀缺条件下的个体表现出更慢的响应时间,表明选择性注意力减少.
脑电图数据显示N2pc振幅较弱,这表明注意力控制受损.
减少的Pd振幅表明干扰器抑制受损,而目标增强 (Nt振幅) 没有受到影响.

结论:

稀缺心态会对选择性注意力产生负面影响,特别是阻碍过掉不相关信息的能力.
这些发现表明,稀缺性会影响认知控制,对政策和实践产生影响.
这项研究强调了在理解注意力过程时考虑心理状态的重要性.

The Availability Heuristic

The Availability Heuristic

A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

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....

Self-Discrepancy Theory

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.
