Effects of MK-801, haloperidol, and SCH 23390 on the percentage of foraged food pellets under Conditions 1, 3, and 4. a Bonferroni post-tests revealed no significant effects of vehicle, MK-801, haloperidol, or SCH 23390 treatment on the percentage of foraged food from both side cages under Condition 1; b rats preferred foraging sweet food pellets to standard food pellets among the four groups under Condition 3. Bonferroni post-tests revealed significant effects of vehicle, MK-801, haloperidol, and SCH 23390 treatment on the percentage of foraged of sweet food pellets compared with standard food pellets. ***p<0.001, represents statistically significant differences compared with foraged sweet food pellets; c when the test rat confronted a rat in one cage with standard food pellets, the percentage of foraged standard food pellets after MK-801 and SCH23390 treatment decreased significantly compared with foraged sweet food pellets in the other cage. No distinct differences between the two kinds of food pellets were observed after vehicle or haloperidol treatment under Condition 4. **p<0.01, ***p<0.001 represents statistically significant differences compared with foraged sweet food pellets
