“Cognitive hierarchy theory of Strategic thinking: behavioral and
neural evidence”
by Giorgio Coricelli
We used functional MRI (fMRI) and eye-tracking to investigate human
mental processes in interactive decision making. Our main goal is to
investigate whether and how a player’s mental processing incorporates
the thinking process of others in strategic reasoning. We apply a
cognitive hierarchy model to classify subject’s choices in experimental
games according to the degree of strategic reasoning so that we can
identify the neural substrates of different levels of strategizing.
According to this model, high-level reasoners expect the others to
behave strategically, whereas low-level reasoners choose based on the
expectation that others will choose randomly. The data show that
high-level reasoning and a measure of strategic IQ (related to winning
in the game) correlate with the neural activity in the medial prefrontal
cortex, demonstrating its crucial role in successful mentalizing. With
the eye-tracking data we were able to evaluate different theories of
limited cognition. Our results are coherent with the existence of
individually heterogeneous patterns of initial responses, which are
based on a set of a priori types. These findings support a cognitive
hierarchy model of human brain and behavior.
We're looking forward to see you there (Frankel Leo u. 30-34) !
