科学领域:
- 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:
- 观察者可以学会抑制高分心概率的视野位置.
- 学习抑制是一种在视觉要求高的环境中管理注意力资源的机制.
研究的目的:
- 调查是否学习视觉抑制转移到不同的搜索任务没有分心.
- 为了确定学习抑制的灵活性,以应对任务和战略的变化.
主要方法:
- 观察者执行了一个额外的单项任务,学习如何抑制容易分散注意力的位置.
- 然后任务切换到T-among-L搜索 (并行或串行),有或没有关于切换的线索.
- 在任务切换后评估了性能,以评估抑制转移.
主要成果:
- 学习的抑制转移到T-among-L任务中,无论搜索策略如何 (并行/串行),都会持续.
- 预示即将到来的任务切换不会影响性能,这表明抑制仍然存在.

Associative Learning
344
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.

Improving Translational Accuracy
10.2K
Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Generalization, Discrimination, and Extinction
532
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

Statistical Analysis: Overview
6.6K
When we take repeated measurements on the same or replicated samples, we will observe inconsistencies in the magnitude. These inconsistencies are called errors. To categorize and characterize these results and their errors, the researcher can use statistical analysis to determine the quality of the measurements and/or suitability of the methods.
One of the most commonly used statistical quantifiers is the mean, which is the ratio between the sum of the numerical values of all results and the...

Regression Toward the Mean
6.3K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Multi-input and Multi-variable systems
106
Cruise control systems in cars are designed as multi-input systems to maintain a driver's desired speed while compensating for external disturbances such as changes in terrain. The block diagram for a cruise control system typically includes two main inputs: the desired speed set by the driver and any external disturbances, such as the incline of the road. By adjusting the engine throttle, the system maintains the vehicle's speed as close to the desired value as possible.
