Do the strategic complexity of the decision environment and the participants’ cognitive ability affect their performance and neural response? You can find the answer in our new paper now (freely) available in @SciReports at nature.com/articles/s4159… 1/7 
We explored the role of cognition and its inter-individual variability in social decision-making. First, we developed a new model of strategic #decisionmaking in repeated interactions to provide a precise measure of the environment’s complexity and participants’ performance. 2/7
Then we tested some empirical predictions of the model on both behavioral and neural data. We showed that deviations from optimal behavior are explained by a combination of higher complexity of the strategic environment and cognitive skills of the individuals. 3/7
The average participants’ outcome was worse in more complex environments and the performance of participants with lower fluid intelligence degraded disproportionally more than for those with higher intelligence. 4/7
Moreover, neural activation correlated with the complexity of the strategic environment, being higher for more complex environments, although brain activity was not modulated by the strategic complexity in the group with the lowest fluid intelligence. 5/7
The effect was observed in a #frontoparietal net involved in task representation in single-agent tasks, but not in the #theoryofmind net involved in reasoning about others’ mental states. Our findings show the importance of cognitive factors in shaping social decision-making. 6/7
It has been a long journey but I really enjoyed this #interdisciplinary #decisionmaking project with @carloreve, Marco Mantovani, @johndylanhaynes & @rusti001 🙂 7/7
