Epigenetic Regulation01:46

Epigenetic Regulation

33.5K
Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

An Overview of Epigenetics

52.0K
Since the early days of genetics research, scientists have noted certain heritable phenotypic differences that are not due to differences in the nucleotide sequence of DNA. Current evidence suggests that these “epigenetic” phenomena might be controlled by a number of mechanisms, including the modification of DNA cytosine bases with methyl groups, the addition of various chemical groups to histone proteins, and the recruitment of protein factors to specific DNA sites via interactions...

Social Proof00:52

Social Proof

31.5K
Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Social Facilitation01:04

Social Facilitation

36.0K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Social Loafing01:37

Social Loafing

38.9K
Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...

Social Scripts02:10

Social Scripts

10.2K
People tend to know what behavior is expected of them in specific, familiar settings. A script is a person’s knowledge about the sequence of events expected in a specific setting (Schank & Abelson, 1977). Essentially, scripts are a particular kind of schema, one containing default values for the features within an event. In the restaurant example, the script's features include the props (e.g., tables, menu, food, and money), the roles to be played (e.g., customer and waiter),...

Area of Science:

  • Social epigenetics
  • Gene-environment interactions
  • Human adaptation

Background:

  • Social environments profoundly influence human health and development throughout life.
  • Epigenetics provides a mechanism for how environmental factors impact gene expression.
  • Understanding these interactions is crucial for comprehending human adaptability.

Purpose of the Study:

  • To explore the role of epigenetics in mediating the effects of social environments on individuals.
  • To investigate how epigenetic modifications adapt to diverse social exposures.
  • To highlight the link between epigenetic plasticity and survival strategies.

Main Methods:

  • Review of current research on epigenetics and social environments.
  • Analysis of epigenetic mechanisms (DNA methylation, histone modification, chromatin remodeling).
  • Examination of how these mechanisms are influenced by micro- and macro-social factors.

Main Results:

  • Epigenetic mechanisms are sensitive to social environmental cues.
  • These modifications can persist over time, influencing long-term responses.
  • Epigenetic plasticity contributes to learning from experiences like stress and comfort.

Conclusions:

  • Epigenetic modifications serve as a bridge between social environments and biological adaptation.
  • Experience-dependent epigenetic changes facilitate survival and coping mechanisms.
  • This research underscores the profound biological impact of our social world.
