Muscles for Facial Expressions01:14

Muscles for Facial Expressions

5.0K
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

Facial Feedback Hypothesis01:24

Facial Feedback Hypothesis

687
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)01:20

Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)

1.7K
Two NMR-active nuclei bonded to a central atom can be involved in geminal or two-bond coupling. Geminal coupling is commonly seen between diastereotopic protons in chiral molecules and unsymmetrical alkenes, among others.
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...

Spin–Spin Coupling: Three-Bond Coupling (Vicinal Coupling)01:22

Spin–Spin Coupling: Three-Bond Coupling (Vicinal Coupling)

1.5K
Vicinal or three-bond coupling is commonly observed between protons attached to adjacent carbons. Here, nuclear spin information is primarily transferred via electron spin interactions between adjacent C‑H bond orbitals. This generally favors the antiparallel arrangement of spins, so 3J values are usually positive.
The extent of coupling depends on the C‑C bond length, the two H‑C‑C angles, any electron-withdrawing substituents, and the dihedral angle between the involved orbitals. The...

G-protein Coupled Receptors01:21

G-protein Coupled Receptors

132.2K
G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

Spin–Spin Coupling: One-Bond Coupling01:17

Spin–Spin Coupling: One-Bond Coupling

1.5K
Coupling interactions are strongest between NMR-active nuclei bonded to each other, where spin information can be transmitted directly through the pair of bonding electrons. While nuclei polarize their electrons to the opposite spins, the bonding electron pair has opposite spins. Configurations with antiparallel nuclear spins are expected to be lower in energy. When coupling makes antiparallel states more favorable, J is considered to have a positive value. The one-bond coupling constant, 1J,...

Summary

Couples appear more alike than previously thought, with perceived personality similarity driving facial resemblance. This finding suggests relationship quality is linked to shared personality traits reflected in facial appearance.

Area of Science:

  • Psychology
  • Social Psychology
  • Human Behavior

Background:

  • Previous research indicates couples exhibit higher facial similarity than non-couples.
  • Facial similarity in couples has been linked to marital satisfaction.
  • The role of extrinsic features and perceived attributes in couple facial similarity remains unclear.

Purpose of the Study:

  • To investigate if facial similarity in couples persists without extrinsic features.
  • To identify specific attributes perceived as similar in couples' faces.
  • To explore the relationship between perceived personality similarity and facial similarity in couples.

Main Methods:

  • Three experiments were conducted to assess facial similarity in couples and non-couples.
  • Participants rated facial similarity with and without extrinsic features.
  • Perceived personality and age similarity were evaluated from faces.

Main Results:

  • Couples showed greater facial similarity than non-couples, even when extrinsic features were removed.
  • Perceived personality and age were more similar in couples' faces.
  • Higher perceived personality similarity correlated with higher facial similarity and couple likelihood ratings.

Conclusions:

  • Facial similarity in couples is not solely based on physical attributes but also on social cognitive judgments of personality.
  • Perceived personality similarity may be a key factor in couple formation and relationship quality.
  • These findings offer insights into the interplay between appearance, personality, and relationship dynamics.
