--All participants were teaching at either the secondary or university level
at the time of the study.
--All of the bilingual teachers reported
studying their second language for more than 7 years, with 7 of the twelve
bilingual teachers beginning their L2 study early in life, during their
elementary education (none reported being raised in a bilingual
environment since early childhood).
--The midsagittal corpus callosum image
was partitioned plane into five subregions using a modification of
Witelson’s method.
