“…Two other differences between Beck and Bidwell's (1974) and Cohen and Olistendorp' s (1976) experiments that might have affected sucrose preference in highly water-deprived rats were number of daily trials and mode of testing.

“…These results replicated earlier fmdings for animals not given such prolonged exposure to each incentive (Beck & Nash, 1969; Beck, Nash, Viernstein, & Gordon, 1972; Beck, Self, & Carter, 1965). Cohen and Obstendorp (1976) and Cohen, Obstendorp, and Ross (in press) carried out experiments similar in design to Beck and Bidwell's (1974) but found reliable sucrose preferences in highly and moderately water-deprived animals (22.5 and 18 h). These recent studies differed from Beck and Bidwell's work in that animals were exposed to a higher concentration of sucrose (20%) and received a series of forced-choice trials prior to freechoice tests for preference.…”

Highly and moderately water-deprived animals (23.5 hand 18 h, respectively) were exposed to 8% sucrose and water or 20% sucrose and water at fixed positions in a two-choice discrimination apparatus. Half the animals in each group received a series of alternating free-and forced-choice trials. The other animals received a series of forced-choice trials prior to a free-choice preference test. A retesting procedure was carried out in which deprivation levels were switched for all animals. Neither mode of training, exposure to incentive, nor concentration of sucrose reliably affected incentive preference. Deprivation level, however, was related to incentive preference. Only animals that were initially moderately deprived developed reliable and consistent preferences to sucrose. Highly deprived animals also developed reliable sucrose preferences after being switched to moderate water deprivation during retesting.Beck and Bidwell (1974) exposed highly waterdeprived (23.5 h) and nondeprived rats to sucrose (8%) and water at fixed positions for a lengthy series of alternating free-and forced-choice trials. Nondeprived animals developed high sucrose preferences, while the water-

“…Under free-choice conditions and limited access to reinforcement, food-deprived and/or water-satiated rats prefer increased sucrose concentrations, while water-deprived rats (22.5-23.5 h) either prefer lower concentrations or show no reliable preferences (Beck & Bidwell , 1974;Beck & Nash, 1969;Beck, Nash, Viernstein, & Gordon, 1972;Beck, Self, & Carter, 1965;Cohen & Tokieda, 1972). With increased access to reinforcement (I min or more per trial) or prewatering, highly deprived animals will develop sucrose preferences (Beck & Nash, 1969;Beck et aI., 1972;Cohen & Tokieda, 1972).…”

Water-deprived rats (23.5 and 18 h) acquired simultaneous discrimination tasks with position of the positive stimulus paired with water and 2Oo~ sucrose. Free-choice trials with S+ simultaneously present at both positions occurred following discrimination acquisition. Animals acquired tasks in which either goal-door and/or floor-texture cues were relevant. All moderately deprived discrimination groups displayed more errors and slower speeds to S+ at the water than at the sucrose side. Only highly deprived animals that acquired a floor· texture discrimination developed similar, but not as great, speed differences. Such speed differences were due to increased speeds to S+ at the sucrose position. All but the highly deprived floor + door learners displayed reliable free-choice sucrose preferences. Moderately deprived animals tended to display greater sucrose preferences than highly deprived animals. Results were discussed in terms of attention and learning as a function of deprivation level.Preference for sucrose solutions has been found to be a function of the type of deprivation in rats. Under free-choice conditions and limited access to reinforcement, food-deprived and/or water-satiated rats prefer increased sucrose concentrations, while water-deprived rats (22.5-23.5 h) either prefer lower concentrations or show no reliable preferences (Beck & Bidwell , 1974;Beck & Nash, 1969;Beck, Nash, Viernstein, & Gordon, 1972;Beck, Self, & Carter, 1965;Cohen & Tokieda, 1972). With increased access to reinforcement (I min or more per trial) or prewatering, highly deprived animals will develop sucrose preferences (Beck & Nash, 1969; Beck et aI., 1972;Cohen & Tokieda, 1972). Cohen, Weir, and Granat (I975) demonstrated that highly water-deprived animals' preference for water over sucrose could be reversed by decreasing fixed intervals from 19 to .25 sec in a one-lick situation. Similar relationships have also been found, when incentives were presented separately (forced-choice condition). Fooddeprived and/or water-satiated animals typically respond (barpress) more vigorously for increased sucrose solutions, while highly water-deprived animals either respond at similar rates to all incentives (water 64% sucrose) (Beck, 1963 ;Oakley, 1965;Rosen & Jacobs, 1968;Tombaugh, 1974) or develop faster rates to water (Beck & Ellis, 1966). Highly water-deprived animals would also begin to respond more vigorously to sucrose than water at the end of lengthy experimental sessions of 30 min (Rosen & Jacobs, 1968).Cohen and Oostendorp (1976) measured both forcedExperiment I in the present study was based on a thesis submitted by the second author in partial fulfillment of the requirements for a master's degree at the University of Windsor.

Saccharin Hoarding by Albino Rats: Further Evidence on Incentive and Object Retrieval

Albino rats were allowed to retrieve dental pledgets soaked in water or pledgets soaked in 1.0% saccharin solution from wooden alleys into their home cages. Under ad lib conditions more saccharin pledgets were hoarded than water pledgets, but during water deprivation this preference was reversed. If rats were given saccharin pledgets alone, hoarding did not decline during water deprivation. Rats showed the ad lib saccharin preference although they did not hoard their normal diet of food pellets, and it was maintained in animals that had received saccharin since weaning. Hence sweetness of taste is a property of objects that can induce hoarding, and the reversal in hoarding during deprivation is due to an increased preference for water rather than a diminished saccharin preference. This indicates that incentive properties of objects are crucial to the expression of this species-typical behavior.
