Outline of Final Research Achievements

Knowledge acquisition is a process in which one actively selects a piece of information from the environment and assimilates it with prior knowledge.
Using human fMRI experiment, I showed a neural mechanism underlying such selectivity in knowledge acquisition. My results suggest that an arrangement of prototypical neural representation based on the prior knowledge facilitates upcoming knowledge acquisition. Therefore, our brain selects an information through deciding types of information to be acquired and preparing the prototypical neural representations.
Additionally, I investigated a rationality governing such selectivity using human behavioral experiment. Using acquisition of novel compositional words as an instance of knowledge acquisition, I showed that we selectively acquire information that effectively confers creative productivity.
