概括
婴儿的面部识别随着年龄的增长而缩小,类似于语音声音感知. 这种"感知缩小"表明,婴儿处理熟悉的类别的一般认知变化.
科学领域:
- 发展心理学是发展心理学.
- 认知神经科学是一种认知神经科学.
- 人类心理学和比较心理学
背景情况:
- 婴儿区分母语声音的能力在6-10个月之间得到改善,而外语声音区分能力则下降.
- 这种发展转变被称为"感知狭窄".
研究的目的:
- 调查在语音处理中观察到的感知缩小是否也发生在面部识别中.
- 为了确定这种现象是特定于语言还是更一般的认知过程.
主要方法:
- 使用视觉对对比程序来测试面部歧视.
- 对比了6个月大,9个月大和成人的能力.
- 测试了人脸和子脸的歧视.
主要成果:
- 六个月大的婴儿在人类和子两种物种的个体之间表现出歧视.
- 九个月大的婴儿和成年人只对人脸有歧视,而不是子脸.
- 这表明,随着年龄的增长,非本地人面孔的歧视能力下降.
结论:
- 这种"感知狭窄"的现象超越了语言,扩展到面部处理.
- 结果表明,早期认知发育背后的神经网络发生了普遍的变化.
- 这种发育转变会影响婴儿如何分类和识别不同物种的面孔.

Imprinting
Behavioral imprinting is observed in some newborn animals and occurs when they develop strong and specific attachments to another animal (usually a parent) following brief, early-life exposures. Offspring imprint onto parents within a brief period after birth or hatching; this time window is called the critical period. Once imprinting occurs, the bond established between the parents and their offspring is usually long-lasting.
Parental Care
Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.
Overview of Regeneration and Repair
Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.

Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
