概括
视觉搜索效率的个体差异与主动控制有关. 更高的主动控制与负线索带来的更大的好处相关,提高了搜索性能并减少了使用负关注模板时的错误.
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.
- 视觉感知 视觉感知 视觉感知
背景情况:
- 负模板通过利用分心特征的预知来改善视觉搜索.
- 在从负线索中获得的好处中存在显著的个体变化.
- 这些个体间差异的认知基础尚未得到充分理解.
研究的目的:
- 调查主动控制效率在解释视觉搜索过程中消极提示效益的个体差异方面的作用.
- 为了确定主动控制是否介导负面注意力模板的有效性.
主要方法:
- 重新分析了一大数据集 (N=139),包括两个研究中的36名参与者的眼睛跟踪数据.
- 使用反应时间 (RT) 变异性来测量个体主动控制效率.
- 分析RT的好处和第一次冲刺行为,以响应负或中性线索.
主要成果:
- 与中性线索相比,具有更高主动控制效率的个体从负线索中获得了更大的RT益处.
- 较高的主动控制与较少的初始冲刺有关,这些冲刺指向被指令分心的物品.
- 这些关系是特定于负的线索,并没有观察到积极的线索.
结论:
- 积极控制效率是负面注意力模板的益处中个体间差异的关键驱动因素.
- 增强的主动控制有助于在视觉搜索中更有效地使用负面线索.
- 了解主动控制为优化视觉搜索策略提供了洞察力.

Stereotypes, Prejudice, and Discrimination
90.1K
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...

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...
