“…As reinforcers, however, sucrose solutions and pellets exhibit other standard properties. For example, just as with food pellets, sucrose pellets promote single alternation patterning (Burns, 1984), suggesting that they leave a stimulus trace that can acquire control over instrumental behavior. Moreover, Burns and Wiley (1984) found evidence that rats can anticipate the occurrence of a 30% sucrose solution when reinforced (R) and nonreinforced (N) trials are administered in regular sequences.…”

“…The failure to obtain contrast effects with sucrose is important (Burns, 1984) because it appears reliably and it parallels the effects obtained under other, perhaps related conditions. Rats with limbic lesions (Franchina & Brown, 1971) or doses of barbiturates (Rosen, Glass, & Ison, 1967) do not show the effect, nor do immature rats (Stanton & Amsel, 1980), goldfish (Lowes & Bitterman, 1967), or turtles (Pert & Bitterman, 1970).…”

Five groups of albino rats were trained in a straight runway for 44 pre-shift trials, 2 trials per day with a 3- to 5-min intertrial interval (ITI). Two of the groups (30-0 and 30-3) received 1 ml of 30% sucrose solution as a reward, two groups (3-0 and 3-3) received an equal volume of 3% sucrose, and one group (0-0) received no reward. During 20 postshift trials, three groups (0-0, 3-0, and 30-0) received no reward, and two groups (3-3 and 30-3) received 3% sucrose. Postshift trials were massed (10/day) with the same ITI as in preshift. The reward shift produced a direct relationship between the amount of preshift reward and resistance to extinction and no evidence of successive negative contrast whether the shift was to smaller or non-reward levels.
