Yawningcan

Yawningcan is a term used in theoretical discussions of contagious yawning to describe a hypothetical unit or construct that captures the spread of yawning through a social network. In this usage, a yawningcan represents both an individual's susceptibility to yawning and their capacity to transmit the cue to others. The term is not a reference to a real device or measurement, but rather a pedagogical tool for modeling social contagion.

Origin and usage: Yawningcan appears in thought experiments and introductory discussions of threshold models and diffusion in networks. It is used to illustrate how small changes to connectivity or individual thresholds can affect the scale and speed of yawning cascades. The etymology combines yawning with can as a metaphor for a “container” of yawning that can be opened by exposure to yawning cues.

Mechanism: In the yawningcan framework, individuals have a baseline probability of yawning and a higher probability when a certain proportion of their connections are yawning. A refractory period follows yawning, limiting immediate re-yawning. Transmission depends on network structure, exposure strength, and context, such as group size and attention.

Applications and limitations: The concept serves as a simplified model to study social contagion and network effects in a tangible way. It does not imply a precise neural mechanism. Real yawning is influenced by physiological state, fatigue, and environmental factors, and contagious yawning shows variability across individuals and situations. The yawningcan model is a simplification intended for teaching and preliminary analysis, not a definitive description of yawning biology.
