概括
恐惧的面孔与转移的目光缩短了对碰撞时间 (TTC) 的估计,信号环境威胁. 这种对TTC的影响,但不是人际距离 (IPD),突出了在动态环境中威胁的检测.
科学领域:
- 心理学 心理学 心理学
- 神经科学是一个神经科学.
- 视觉感知 视觉感知 视觉感知
背景情况:
- 估计碰撞时间 (TTC) 和人际距离 (IPD) 对安全和社会互动至关重要.
- 众所周知,面部表情和凝视方向会影响面部处理,但它们对迫在眉的面部时空感知的综合影响尚不清楚.

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...

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.
