Effects of memory on spatial heterogeneity in neutrally transmitted culture.

Bentley, R.A. and Caiado, C.C.S. and Ormerod, P. (2014) 'Effects of memory on spatial heterogeneity in neutrally transmitted culture.', Evolution and human behavior., 35 (4). pp. 257-263.


We explore how cultural heterogeneity evolves without strong selection pressure or environmental differences between groups. Using a neutral transmission model with an isolation-by-distance spatiality, we test the effect of a simple representation of cultural ‘memory’ on the dynamics of heterogeneity. We find that memory magnifies the effect of affinity while decreasing the effect of individual learning on cultural heterogeneity. This indicates that, while the cost of individual learning governs the frequency of individual learning, memory is important in governing its effect.
