Memory is the core of historical research, and due to differences in subjects, it can be divided into individual historical
memory, group historical memory, and cultural and historical memory between
groups. The “empathy” function of the brain can trigger the emotion of "empathy"
and connect the three memories. This study conducted experiments on subjects
with different educational backgrounds, genders, and historical knowledge
levels, and used fMRI technology to observe the brain responses of subjects
when viewing war pictures, revealing the advanced cognitive function network, visual
information processing network, and negativity. Changes in activation levels of
emotional brain regions. When the subjects watched the Anti-Japanese War
picture group, the activation level of the core area and regulatory area in the
brain responsible for “empathy” increased significantly, directly mobilizing
the “historical memory” of the brain and highlighting the importance of
historical education——strengthening the connection of cultural memories between
groups thus strengthens national identity and patriotism. In addition, there
are significant differences in the brain activation levels of subjects with
different genders and education levels. The brains of women with higher levels
of education show the most active “empathy” level, and they are more able to
show “sympathy with the same enemy” attitude. Research not only demonstrates
the importance of individual differences in perceiving historical events, but
also proves the role of historical memory in maintaining social consensus and
cohesion of groups.
