- 计算神经科学是一种神经科学.
- 听觉感知是一种听觉感知.
背景情况:
- 腹部说话后效应 (VAE) 表明,在视听刺激后,感知到的声音位置发生了变化.
- 准确的VAE需要对准以头为中心 (听觉) 和以眼为中心 (视觉) 的参考框架.
- 之前的研究在VAE的占主导地位的参考框架方面产生了不同的结果.
研究的目的:
- 开发一个解释VAE神经机制的计算模型.
- 调查VAE所涉及的参考框架,并协调不一致的实验发现.
- 为了建模一种与萨卡迪反应观察到的新型VAE类现象.
主要方法:
- 开发了一个计算模型,从以头为中心的听觉图和以头为中心的视觉转换开始.
- 扩展模型版本包含以眼睛为中心的视觉信号和视线依赖的衰减来解释混合数据.
- 一个经过修改的模型版本解决了受响应方法 (saccades) 影响的VAE现象.
主要成果:
- 模型模拟表明,视角方向依赖的衰减主要解释混合VAE结果.
- 该模型表明,腹部说话后效应的参考框架主要以头部为中心.

Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

01:24Facial Feedback Hypothesis

Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Newton’s first law is usually considered to be a statement about reference frames. It provides a method for identifying a special type of reference frame: the inertial reference frame. In principle, we can make the net force on a body zero. If its velocity relative to a given frame is constant, then that frame is said to be inertial. So, by definition, an inertial reference frame is a reference frame where Newton's first law holds valid. Newton's first law applies to objects with...

A reference frame accelerating or decelerating relative to an inertial frame is a non-inertial frame. To help understand this, consider what taking off in an airplane, turning a corner in a car, riding a merry-go-round, and the circular motion of a tropical cyclone all have in common. All these systems are accelerating, decelerating, or rotating relative to the Earth; hence, they all are non-inertial frames. All these systems exhibit inertial forces, which merely seem to arise from motion,...

01:25The Anchoring-and-Adjustment Heuristic
7.3K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

00:56Attribution Theory
13.0K
Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958).
