科学领域:
- 神经科学是一个神经科学.
- 感知 感知 感知 感知
- 发动机控制器的控制器
背景情况:
- 大脑整合视觉和自身感知信息来估计手的位置.
- 由改变的视觉反引起的视觉-自身感知不匹配,可以导致运动适应和感知重新校准.
- 感知重新校准的机制比运动适应更不了解.
研究的目的:
- 调查视觉-自身感知不匹配率是否影响感知重新校准,而不依赖于运动适应.
- 为了在不同的不匹配引入速度下比较重新校准动态.
主要方法:
- 三组在没有明确的错误反的情况下,在缓慢,中等或快速速度下经历了70毫米的视觉-自身感知不匹配.
- 在确定和维持不匹配后,测量了参与者的重新校准.
- 该研究的重点是感知再校准,而不是运动适应.
主要成果:

Hindsight Biases
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?
Relationship Formation
What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...
Factors Affecting Perception
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.

Self-Discrepancy and Its Effects
Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...
Actor-Observer Effect
The actor-observer effect, a cognitive bias closely linked to the fundamental attribution error, refers to the tendency for individuals to attribute their behavior to external, situational factors while explaining others’ behavior in terms of internal, dispositional traits. This asymmetry in attribution significantly influences social perception and judgment.Cognitive Mechanisms Behind the EffectTwo primary psychological mechanisms contribute to the actor-observer effect: differences in visual...
First Impression
First impressions play a crucial role in social perception, shaping how individuals assess others in professional, academic, and interpersonal contexts. Psychological research highlights the significance of cognitive biases, such as the primacy and recency effects, which influence how people interpret and recall information.The Primacy Effect and Cognitive AnchoringThe primacy effect describes the tendency for initial information to impact judgment disproportionately. When individuals encounter...
