概括
具有更多项 (数量) 的视觉刺激被认为持续时间更长. 这种效应取决于参与者如何判断持续时间,这表明自上而下的认知过程会影响大小感知.
科学领域:
- 认知心理学 认知心理学
- 感知科学 感知科学 感知科学
- 人与计算机的交互
背景情况:
- 以前的研究表明,较大的视觉刺激被认为具有更长的持续时间.
- 这种持续时间大小的错觉与定性 (相同/不同) 的判断相比,与定量 (更长/更短) 的判断相比,随着定性 (相同/不同) 的判断而减少.
研究的目的:
- 调查视觉数量和感知时间之间的相互作用.
- 要确定数量-持续时间效应是否受到响应类型和任务需求的调制.
主要方法:
- 参与者判断了不同数量的点云的持续时间.
- 响应类型包括定量 (较长/较短) 和定性 (相同/不同) 的判断,以及时间运动复制任务.
- 任务难度和感官精度被控制并与实验进行比较.
主要成果:
- 在量化任务中,较大的数量被认为持续时间较长 (实验1和4).
- 在定性任务 (实验2) 或运动复制任务 (实验3) 中没有观察到显著的数量-持续时间效应.
- 观察到的干扰并不能归因于任务难度或感官精度的差异.
结论:
- 数量和时间感知之间的功能相互作用不是主要由共享的自下而上的大小编码机制驱动的.
- 高层次的,自上而下的认知过程,特别是那些参与决策和响应选择的认知过程,在调解数量-时间干扰方面发挥着关键作用.
- 使用与大小相关的响应代码显著影响跨域大小相互作用.

01:37Reason and Intuition
6.5K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective.
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...
