Social network structure has been argued to shape the structure of languages, as well as affect the spread of innovations and the formation of conventions in the community. Specifically, theoretical and computational models of language change predict that sparsely connected communities develop more systematic languages, while tightly knit communities can maintain high levels of linguistic complexity and variability. However, the role of social network structure in the cultural evolution of languages has never been tested experimentally. Here, we present results from (...) a behavioral group communication study, in which we examined the formation of new languages created in the lab by micro‐societies that varied in their network structure. We contrasted three types of social networks: fully connected, small‐world, and scale‐free. We examined the artificial languages created by these different networks with respect to their linguistic structure, communicative success, stability, and convergence. Results did not reveal any effect of network structure for any measure, with all languages becoming similarly more systematic, more accurate, more stable, and more shared over time. At the same time, small‐world networks showed the greatest variation in their convergence, stabilization, and emerging structure patterns, indicating that network structure can influence the community's susceptibility to random linguistic changes (i.e., drift).

Divide me from Myself. Love and Alterity in Rousseau Rousseau affirms that love is the extension of self-love to the others. This theory confronts with a tradition that considers the loved person as «another self», an alterity of selfness that the notion of extension—as we maintain—suppresses. Our thesis is that extended self-love is a form of amour-propre directed to a chimera embodied by means of a plastic imagination that adorns, embellishes the real beings with imaginary beings, rendering them loveable. Thus (...) Julia, the character, incarnates in Mme. Houdetot, the person, who therewith disappears. Lastly the others appear only in the joy of the innocent, once the extension, that is to say, love, disappears. Consequently we must change our subtitle in order to summarize our thesis: love or alterity. -/- Rousseau sostiene que el amor es la extensión del amor de sí en otro. Esta teoría se opone a una tradición que considera al amado como «otro sí mismo», una alteridad de la ipseidad que la noción de extensión, proponemos, suprime. Nuestra tesis es: el amor de sí extendido es un modo del amor propio que se dirige a una quimera encarnada gracias a una imaginación plástica que orna, reviste los seres reales con seres imaginarios, haciéndolos amables. Julia, el personaje, se encarna en Mme. Houdetot, la persona, quien desaparece. Finalmente, el otro sólo aparece en la alegría del inocente, ya suprimida la extensión, por lo tanto, el amor. Debemos pues modificar nuestro subtítulo para sintetizar nuestra tesis: amor o alteridad. (shrink)
