  The activation of scientific concepts (such as association) is not only an
important way for children to organize scientific knowledges, but also an
important way for them to learn complex concepts (such as compound concepts
composed of multiple knowledge points). Inspired by the details of a primary
electrical lesson, we used the E-Prime software to study the activation of
concepts inside and outside the electrical unit by students with different
electrical knowledge levels (taking reaction time as the main index). The
results showed that: 1. the levels of basic knowledge was negatively correlated
with the cross domain activation ability of concepts, that is, the worse the
basic knowledge, the faster the cross domain activation speed (P<0.05); 2. The
better the basic knowledges, the closer the activation behavior is to science
teachers. Conclusion: 1. the poorer the basic knowledges, the stronger the
cross domain association ability and the more active the thinking; 2. The
reason for this phenomenon may be human's thinking is patterned; 3. Therefore,
there is a potential logical contradiction in the view that divergent thinking
is the psychological basis of creativity.
