Nature and Nurture01:10

Nature and Nurture

20.4K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Polygenic Traits01:18

Polygenic Traits

65.6K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

Gene-Environment Interactions01:20

Gene-Environment Interactions

268
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...

Influence of Parents and Peers on Identity

47
Adolescence is a pivotal period of identity formation, during which individuals begin to answer questions central to their sense of self, such as "Who am I?" and "Who do I hope to become?" Both parents and peers play critical roles in guiding adolescents through this complex developmental phase.
Parental Influence on Identity Development
Parents serve as primary guides and managers in an adolescent's life, offering support instrumental in decision-making and personal growth....

Signs of Puberty

279
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Variation: Normal Distribution, Range, and Standard Deviation02:32

Variation: Normal Distribution, Range, and Standard Deviation

22.2K
In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...

Area of Science:

  • Child health and nutrition
  • Developmental economics
  • Behavioral economics

Background:

  • Child stunting affects 150 million children globally, impacting cognitive and economic outcomes.
  • Understanding determinants of growth retardation is crucial for effective public policy.
  • Parental preferences and community norms play a role in child health outcomes.

Purpose of the Study:

  • To model parental nutritional and health choices with reference-dependent preferences.
  • To analyze how parental targets for child height are influenced by community reference points.
  • To decompose the effects of a protein-supplementation intervention on child height.

Main Methods:

  • Developed a model of nutritional choices and health incorporating reference-dependent preferences.
  • Used height as the targeted health outcome for children.
  • Explored exogenous variation in reference height from a Guatemalan protein-supplementation experiment.
  • Estimated model parameters using empirical data.

Main Results:

  • Reference height is an equilibrium outcome determined by previous cohorts' choices.
  • Changes in reference points accounted for 65% of the height difference in children.
  • This effect was observed in the sixth annual cohort after the intervention's start.

Conclusions:

  • Parental concern for child height relative to a reference population is a significant factor in child growth.
  • Interventions aimed at improving child health must consider the influence of social reference points.
  • Understanding reference-dependent preferences can refine public health policies for child nutrition.
