概括
婴儿的面部处理在第一年缩小了. 有限的种族照顾者接触并没有显著影响婴儿面部偏好,这表明这些偏好随着年龄的增长而减少.
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.
- 婴儿的感知婴儿的感知.
背景情况:
- 婴儿在生命的第一年经历感知缩小,影响面部处理.
- "其他种族"效应 (ORE) 表明识别或歧视不同种族面孔的能力降低.
- 了解种族暴露如何影响婴儿面部偏好对于发育研究至关重要.
研究的目的:
- 调查有限与多样化的种族照顾者暴露对婴儿看起来偏好不同种族面孔的影响.
- 为了检查这些偏好如何从4个月到12个月的年龄发展.
主要方法:
- 在47名婴儿身上使用了观察时间范式.
- 婴儿在4个月,6个月,8个月,10个月和12个月被评估.
- 记录了护理人员的种族暴露 (同质与多样性).
主要成果:
- 婴儿通常有同质的种族照顾者暴露.
- 除了在10个月之外,在单种族和多种族暴露组之间没有发现显著的差异.
- 婴儿表现出面部均的凝视分配,并没有表现出自己的种族偏好.
结论:
- 种族照顾者暴露似乎对婴儿面部偏好的影响很小.
- 在婴儿时期,面部偏好倾向于随着年龄的增长而下降.
- 需要进一步研究种族偏好发展对神经行为和社会影响.

Epistasis
50.0K
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...

Background and Environment Affect Phenotype
7.4K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Position-effect Variegation

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

Genetic Variation
1.2K
Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.

Teratogenicity
3.9K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
