Abstract

Payoff-biased cultural learning has been extensively discussed in the literature on cultural evolution, but where do payoff currencies come from in the first place? Are they products of genetic or cultural evolution? Here we present a simulation model to explore the possibility of novel payoff currencies emerging through a process of theory construction, where agents come up with “channels” via which different cultural traits contribute to some ultimate payoff and use such “channels” as intermediate payoff currencies to make trait-updating decisions. We show that theory-building as a strategy is mostly favored when the noise associated with the ultimate-level payoff is high, selective pressures are strong, and the probability of arriving at the right theory is high. This approach provides insights into both the emergence of payoff currencies and the role of cognition for causal model building. We close by discussing the implications of our model for the broader question of causal learning in social contexts.

Resumen

El aprendizaje cultural sesgado en términos de recompensa ha sido extensivamentediscutido en la literatura de la evolución cultural, ¿pero de dónde vinieron los valoresde compra en primer lugar? ¿Son ellos productos de evolución genética o cultural?Aquí presentamos un modelo de simulación para explorar la posibilidad de unos val-ores de recompensa novedosos emergiendo a través de un proceso de construcciónde una teoría, donde los agentes idearon “canales” a través de los cuales caracterís-ticas culturales diferentes contribuyen a un último pago y usan tales “canales” comoformas de pago intermedio para tomar decisiones de actualización de características.Mostramos que la construcción de la teoría como una estrategia es en su mayoríafavorecida cuando el ruido asociado con el último nivel de pago es alto, las presionesselectivas son altas y la probabilidad de llegar a la teoría correcta es alta. Esta aprox-imación provee conocimiento tanto en la emergencia de medios de pago como en elrol de la cognición en la construcción de modelos causales. Concluimos discutiendo lasimplicaciones de nuestro modelo para la cuestión más amplia del aprendizaje causalen contextos sociales.
