Esta hip\u00f3tesis se asoci\u00f3 con datos obtenidos de estudios de primates a principios\u00a0de los 90s , pero ahora, 20 a\u00f1os despu\u00e9s, la imagen es m\u00e1s complicada. Por un lado, el n\u00famero de especies de primates para el que tenemos datos cerebrales y grupales ha aumentado a 238. Aunque los factores sociales a\u00fan parecen jugar un papel importante para un subconjunto de especies, para otros son los factores ecol\u00f3gicos los que han estado impulsando la presencia del cerebro grande. Por otro lado, la hip\u00f3tesis de que la estructura del cerebro es modular ha quedado desacreditada y se puede ver m\u00e1s como una computadora de red que puede resolver problemas. En este proyecto, continuamos el modelado matem\u00e1tico de la hip\u00f3tesis del cerebro social, pero con la visi\u00f3n de un concepto de cerebro social m\u00e1s reactivo. En particular, examinamos c\u00f3mo los costos cambiantes de crear y mantener afiliaciones sociales que no sean familiares (tener amigos), tal como lo permiten las redes sociales y otras tecnolog\u00edas digitales, afectan la capacidad humana para procesar problemas sociales complejos.<\/p>\n<figure style=\"width: 381px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1082 alignleft\" src=\"http:\/\/dccs.udd.cl\/files\/2018\/03\/El-cerebro-social-reactivo-e1520015371333.png\" alt=\"El cerebro social reactivo\" width=\"381\" height=\"263\" \/><figcaption class=\"wp-caption-text\"><br \/>Fig. El efecto de los par\u00e1metros de costo en el nivel de ruido \u00f3ptimo de un agente individual: en alg\u00fan rango de par\u00e1metros, es \u00f3ptimo que el agente tenga un lenguaje menos e thanciente que los dem\u00e1s, pero en otro lugar la mejora es \u00f3ptima.<\/figcaption><\/figure>\n<p>&nbsp;<\/p>\n<blockquote>\n<h3><span style=\"color: #800080\">PSICOLOG\u00cdA SOCIAL<\/span><\/h3>\n<p style=\"text-align: justify\"><span style=\"color: #800080\">Tamas es parte del Social and Evolutionary Neuroscience Research Group (SENRG), Centro de Oxford dirigido por Robin Dunbar y que estudia el comportamiento humano.
