  This article reviews the psychological and neuroscience achievements in
concept learning since 2010 from the perspectives of individual learning and
social learning, and discusses several issues related to concept learning,
including the assistance of machine learning about concept learning. 1 In terms
of individual learning, current evidences shown that the brain tends to process
concrete concepts through typical features (shared features); And abstract
concepts, semantic processing is the most important cognitive way. 2 In terms
of social learning, Interpersonal Neuro Synchronization (INS) is considered the
main indicator of efficient knowledge transfer (such as teaching activities
between teachers and students), but this phenomenon only broadens the channels
for concept sources and does not change the basic mode of individual concept
learning. Ultimately, this article argues that the way the human brain
processes concepts depends on concept's own characteristics, so there are no
'better' strategies in teaching, only more 'suitable' strategies.
