  Corrections motivated by chiral symmetry arguments have long been known to
give important contributions to hadronic observables, particularly at low
momentum transfer. It is possible to separate these approaches into two broad
groups; either the corrections are implemented at the parton level, or at the
hadron level. We explore the results of incorporating pion loop corrections at
the hadron level to a calculation of electromagnetic form factors in the NJL
model. These calculations are compared with the result of an earlier
implementation of pion loops at the parton level using the same NJL model
formalism. A particular parameter set yields a good description of low energy
nucleon properties within both approaches. However, for the $\Sigma^-$ there is
a remarkable improvement when the chiral corrections are implemented at the
hadronic level.
