Abstract Cumulative technological culture is defined as the increase in efficiency and complexity of tools techniques over generations. While role social cognitive skills cultural transmission has been long acknowledged, recent accounts have emphasized that non-social such technical reasoning, a form causal reasoning aimed at understanding physical world, are also work during content. Here we contribute to this double process approach by reporting an fMRI study about neurocognitive origins learning. Participants were shown videos depicting tool-making episodes three social-learning conditions: Reverse engineering, Observation Teaching. Our results showed technical-reasoning network, centred around Area PF left inferior parietal cortex, was preferentially activated when watching episodes. Additionally, teaching component related activation right middle temporal gyrus. We propose heart our cognition improve learner’s helping them concentrate on important parts technology. Thus, both social-cognitive may play key evolution technologies.

Although the theoretical foundations of modern field cultural evolution have been in place for over 50 y, laboratory experiments specifically designed to test evolutionary theory only existed last two decades. Here, we review main experimental designs used evolution, as well major findings related generation variation, content- and model-based biases, cumulative nonhuman culture. We then identify methodological advances that demonstrate iterative improvement methods. Finally, focus on one common critique experiments, appropriate individual learning control condition needed culture, present an original investigation relevant this critique. Participants completed a combinatorial innovation task allowing time four commonly designs/conditions: social learners chains, groups, experiencing extended session lasting same accumulated entire chain or group, repeated sessions adding up total time. found resulted superior performance any other condition. discuss these light relevance specific criticism previous studies purport demonstrated also use our broad trade-offs participants face when individually socially different contexts, including variable acquisition costs, redundancy effort cognitive motivational fatigue.
