Copycat suicide model
This agent-based model simulates various cultural processes that are thought to influence the phenomenon of copycat suicide. Parameters control the strength of social learning, prestige bias, one-to-many transmission, homophily and individual differences in suicide risk (see published paper for details). The coloured grid indicates the spatial distribution of suicides over successive time periods.
Random copying model
This program generates log-log plots of cultural trait distributions assuming different individual-level cultural learning biases, including random copying and various forms of frequency-dependent biases (e.g. conformity, anti-conformity). While random copying generates scale-free (straight line) power-law distributions (see also Bentley, Hahn & Shennan, 2004), different frequency-dependent biases produce interesting deviations from the power-law distribution.
