Abstract: Two experiments were designed to test the hypothesis that approach-avoidance conflict becomes associated with hunger cues during conflict acquisition in a straight alley runway, and that these cues lose some of their avoidance properties during that period of time spent outside the conflict situation. When the animals are returned to the alley, the avoidance component associated with hunger cues is already extinguished, and the animal makes the goal response. Thirty-six naive male albino rats of the Sprague-Dawley strain were used in experiment I. An approach-avoidance conflict was generated in the traditional manner by first pairing the approach response with food and, after firmly establishing the approach component, pairing it with shock until the animal failed to make any forward movement. In order to insure that the gradients intersected at the same point, Ss were given extinction trials until they moved from 8 to 12 in. down the alley, and matched. They were then randomly assigned to three groups: an alley group, a home-cage satiation group, and a home-cage deprivation group. These designations refer to where the time following the conflict training was spent and, for the home-cage groups, the drive condition (satiation or deprivation) during this period. Trial-by-trial extinction (two trials per day) was administered until the alley group extinguished the avoidance response to the criterion of two successive goal responses. As soon as the alley group reached the criterion, the home-cage groups were placed on 100% deprivation for 24 hours, and subsequently were given all extinction trials in one day until the criterion was reached.
