Abstract
Rats, trained on a C-I problem, exhibited no differences between IDS and EDS, whereas rats trained on a V-I problem did. Furthermore, the C-I problem was learned faster than the V-I problem originally. These data suggest that the C-I condition was not sufficient for the acquisition of a mediator in the present experiment.
