| Popis: | Electric shocks were delivered to rats through a subcutaneously implanted back electrode. Experiment 1 evaluated the relationship between number of paws grounded and total power dissipated in the rat. In Experiment 2, the threshold of shock-induced vocalization, a putative index of aversiveness, was found to be positively correlated with the number of paws grounded. These findings suggest that when the backshock technique is used, the aversiveness of shock potentially can be modified by the posture adopted by the experimental animal. Caution should be exercised, therefore, in attributing deficits in escape behavior following inescapable shock administered with back electrodes to learned helplessness. |
