Group Polarization01:01

Group Polarization

34.3K
Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

Amplifying Signals via Enzymatic Cascade

8.4K
When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze...

Intracellular Signaling Affects Focal Adhesions

2.6K
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

5.3K
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

Activation of Integrins01:15

Activation of Integrins

3.4K
Integrins bind ligands and transmit information from outside the cell to inside or vice-versa through an "outside-in signaling" or "inside-out signaling."
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding...

Social Proof00:52

Social Proof

27.6K
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.

Summary

Mobilization to extremist action is linked to discussing operational planning and logistics, not just grievances. Understanding the "how-to" of action is key for collective action theories.

Area of Science:

  • Social Psychology
  • Computational Social Science
  • Political Science

Background:

  • Psychological theories often focus on motivations for action, neglecting mobilization processes.
  • Understanding online behaviors is crucial for studying mobilization to extremist action.

Purpose of the Study:

  • To investigate online communication patterns differentiating individuals who mobilize to extremist action from those who do not.
  • To identify specific online behaviors associated with mobilization processes.

Main Methods:

  • Comparative analysis of social media posts from individuals who mobilized versus those who did not.
  • Utilized content analysis, topic modeling, and machine learning on a dataset of 119,473 posts.
  • Examined communication content related to ideology, hate speech, violent action, planning, and logistics.

Main Results:

  • Communicating ideological or hateful content was not associated with mobilization.
  • Mobilization was positively correlated with discussions of violent action, operational planning, and logistics.
  • Online behavior related to capability and planning, not just grievances, predicted mobilization.

Conclusions:

  • Mobilization to extremist action is better explained by the acquisition of practical 'know-how' and capabilities, rather than solely by motivations or grievances.
  • Collective action theories should incorporate the practical aspects of planning and logistics in understanding mobilization.
  • Online communication data offers insights into the mechanisms of extremist mobilization.
