Sex differences in vicarious trial-and-error behavior during radial arm maze learning

We investigated sex differences in VTE behavior in rats during radial arm m aze learning. Females made more VTEs than males, although there were no sex differences in learning. Further, VTEs and errors were positively correlat ed during the latter testing sessions in females, but not in males. This se x difference may be a reflection of differences between the sexes in confli ct behavior or cognitive strategy while solving the maze. (C) 2000 Elsevier Science Inc. All rights reserved.
