“…The finding was apparently contradictory to the preparatory response hypothesis. Badia and Abbott (1980) also found no differential modification of shock contact time between rats in signaled-and in unsignaled-shock conditions. Fanselow (1979), however, on the basis of his failure to find the PSS phenomenon in rats injected with the opiate antagonist naloxone, came to the conclusion that "the signal causes conditioned release of an endogenous analgesic that decreases the aversiveness of shock" (p. 73).…”

The present article reviews rat experiments using aversive stimuli in which some element of uncertainty was involved. Nine cases of conditions that produce uncertainty are described, and the relevant experimental facts are examined. Rats were found to prefer situations involving certainty to those involving uncertainty, and the rats' basal rate of responding was found to be less in suppression situations involving uncertainty about aversive environmental events than in those involving relative certainty. These results were obtained when the aversive stimuli the rats received were physically matched in quantity among the conditions compared. The results are discussed with reference to five hypotheses. It is concluded that the function of the concept of uncertainty is to organize a class of studies that are otherwise unrelated to each other.

“…However, available evidence does not support this coping response interpretation. Badia and Abbott (1980) and Imada, Mino, Sugioka, and Ohki (1981) measured shock contact during both signaled and unsignaled shock. In both studies shock contact was greater during signaled shock (although the difference was slight).…”

Previous articles have reviewed the behavioral literature and concluded that predictable shock conditions are less aversive than unpredictable shock conditions. This article reviews the literature on predictable and unpredictable shock conditions relative to physiological measures of stressfulness and considers the possible role of stress-induced analgesia in both the physiological and behavioral effects. It finds that unpredictable conditions are physiologically more stressful than predictable conditions when subjects are exposed to them for one or a few sessions and parameters of stress are relatively severe. However, predictable conditions may be more stressful than unpredictable conditions when sessions are long and extend over days and parameters of stress are less severe. The effect of extended stress appears to depend upon the physiological measure used. These findings are discussed in terms of the phasic versus chronic nature of predictable versus unpredictable stress and the organism's ability to adapt physiologically to these conditions. Finally, the data on stress-induced analgesia are reviewed. We conclude that stress-induced analgesia does not significantly contribute to either preference for predictable over unpredictable stress or their differential physiological effects.

“…Shock was generated by a constant-wattage shocker-scrambler (BRS/LVE Model SGS-001) and delivered to the grid rods, walls, and divider of the shuttle box. Parameters of shock (0.75 mW, 0.5 s) were identical to those used in previous demonstrations of preference for signaled over unsignaled shock (e.g., Abbott & Badia, 1979; Badia & Abbott, 1980). The Sonalert described in Experiment 1 delivered 2400-Hz tones at 82 dB (C) (background < 70 dB [C]).…”
