Conclusion
In summary, the experiments performed here indicate that the
visual representations of different emotional expressions overlap
and interact with identity representations. More specifically, it
would appear that at least two elements underlie overlapping
expression representations; an identity-dependent representation
and an identity-independent representation. Taken alongside
adaptation research targeting individual expressions (e.g.,
Campbell & Burke, 2009; Fox & Barton, 2007), the present study
also indicates that cross-emotion adaptation reconfigures the same
computational space that codes individual expressions.
