|February 6, 2026
概括
在感官竞争期间学习集中注意力会永久改变视觉感知. 训练改变了感知对比度,表明了主观外表的重新校准,而不仅仅是改善了歧视.
科学领域:
- 神经科学是一个神经科学.
- 认知心理学 认知心理学
- 视觉感知 视觉感知 视觉感知
背景情况:
- 选择性注意力可以暂时修改视觉感知.
- 目前尚不清楚这些注意力对外观的影响是否可以被学习并成为持久的.
研究的目的:
- 调查在感官竞争条件下训练注意力是否会导致感知视觉对比度的持久变化.
- 为了确定这种训练是否重新校准了主观的视觉外观.
主要方法:
- 参与者接受了为期七天的指导任务培训.
- 训练涉及固定目标位置与突出的分心器 (感官竞争) 或没有分心器.
- 在训练前和训练后,使用主观平等点 (PSE) 测量感知对比度.
主要成果:
- 在感官竞争下的训练引起了感知对比度的"推拉"转变.
- 训练位置的刺激似乎具有更高的对比度,而未经训练位置的刺激似乎具有更低的对比度.
- 没有分心的训练提高了任务性能,但没有改变感知对比度.
结论:
- 通过注意力训练解决感官竞争导致主观视觉外观的持久重新校准.
- 这些对感知的学习效应是强大的,对新刺激进行概括,并且不仅仅是由于响应偏差的改进.

Competition
24.9K
When organisms require the same limited resources within an environment, they may have to compete for them. Competition is a net-negative interaction. Even if two competing individuals or populations do not interact directly, the overall fitness of both competitors is lowered as a result of not having full access to the limited resource.

Confirmation Biases
8.3K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Hindsight Biases
4.3K
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Bias
7.4K
Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

Brick Durability, Strength, and Appearance
682
Brick durability, strength, and appearance are crucial factors in construction, influencing the choice of bricks for specific applications. The process of freeze-thaw, for instance, significantly affects brick durability. This phenomenon occurs when water absorbed by a brick expands as it freezes, potentially causing damage when it melts and refreezes. Bricks are graded for durability: SW-grade bricks are the most durable, offering high strength and low water absorption, followed by MW-grade...

Impression Management Techniques I: Managing Appearances
220
Appearance is a multidimensional aspect of self-presentation that encompasses observable attributes such as clothing, grooming, speech, and nonverbal behavior. These elements are often strategically managed to align with socially constructed expectations in different settings. For instance, individuals tailor their appearance during job interviews, social gatherings, or athletic events to meet the perceived norms of those environments.Contextual Adaptation and Social SignalsThe research...
