Where do scientists’ superior abilities originate from when generating a creative idea? What
different brain functions are activated between scientists and i) general academic high
school students and ii) science high school students when generating a biological hypothesis?
To reveal brain level explanations for these questions, this paper investigated neural
connectivity differences between general and science high school students and biologists
during hypothesis-generating and hypothesis-understanding using fMRI. Researchers designed
two sets of task paradigm on biological phenomena, one for hypothesis-generating
and the other for hypothesis-understanding. Thirty-six healthy participants (twelve participants
per group) were given hypothesis generating and understanding tasks. Results showed
strong interconnections of functional connectivity in the biologist group, which is acknowledged
as possessing superior hypothesis generation skills. The group was also found to
have significant functional connectivity between the frontal cortex and the mesolimbic system,
which has been documented as the fronto-striatal pathway. Moreover, the biologist
group recorded higher interconnections in other functional connectivities known to be associated
with hypothesis-generating. Taken together, it can be concluded that the hypothesisgenerating
skill gap between groups resulted from activation of particular regions as well as
interconnections of functional connectivity related to network fluidity. Specially, the biologists’
hypothesis-generating superior skill resulted from highly strengthened interconnections
of functional connectivity.
