  • Marcel Montrey's mathematical model showing how  humans' unique skills in hi-fidelity social learning  explains their unique ability for cumulative cultural evolution was published in the Proceedings of the Royal Society B  (June 2020). See the abstract and URL under PUBLICATIONS / Evolution.
  • Ardavan Nobandegani's article resolving the centuries-old St. Petersburg Paradox was published in Topics in Cognitive Science 2020. Our earlier paper on this topic won the award for Best Computational Modeling Paper on Higher-level Cognition at the 41st Annual Conference of the Cognitive Science Society, July 2019. This paradox concerns a lottery with infinite expected payoff, on which people are nevertheless willing to place only a very small bet. See the journal version published in Topics in Cognitive Science, under PUBLICATIONS / Decision making. Or RESEARCH HIGHLIGHTS / Resolving the St. Petersburg paradox.
  • Our article presenting a comprehensive systems model of memory reconsolidation and extinction was published in the journal Hippocampus:  Helfer, P. & Shultz, T. R. (2020). A computational model of systems memory reconsolidation and extinction. Hippocampus, 30, 659-677. See the Abstract and URL under PUBLICATIONS / Memory.
  • Our article modeling Neanderthal replacement by anatomically modern humans was published in June 2019 in Proceedings of the Royal Society B. A current controversy is whether this replacement was caused by differential fitness or pure random drift. Our stochastic simulations and math model strongly support the differential-fitness explanation. Pure drift is too slow, too uncertain, and incorrectly predicts Neanderthal incursions into Africa. See the abstract and URL under PUBLICATIONS / Evolution.
