Substitution and caloric regulation in a closed economy

Article Abstract:

The slopes of demand curves for food of monkeys and rats are unaffected by saccharin solution and sucrose consumption. As a result, they defend their daily consumption of the complementary elements of food by increasing the daily output of activities for which they are conditioned to believe cause food to appear. When sucrose and food intakes are rescaled in terms of calories, increases in the fixed ratio of these activities reduces food intake of rats. This increases caloric intake from sucrose with little reduction in the total caloric intake. This indicates that rats compensate for lost food calories and make adjustments in their caloric consumption.

Behavioral momentum: the effects of the temporal separation of rates of reinforcement

Article Abstract:

An experiment was conducted to examine the effects of temporal separation of rates of reinforcement on resistance to change and the impact of differences in stimulus and reinforcer relations between simple and complex schedules. It was shown that prefeeding and extinction data in complex schedules affirm the behavioral momentum model which says that rates of reinforcement and resistance to change is directly related in complex schedules. However, extinction data did not support and prefeeding data only partially supported the behavioral momentum model under two daily alternating schedules.

Reversed schedule effects in closed and open economies

Article Abstract:

Reversed scheduled effects in close and open economies have been studied in pigeons. The pigeons were fed based on fixed-interval, fixed-ratio or random-interval schedules. The food was regulated at each meal during the closed economy phase but the birds were given supplemental feeding by as much as 80% of their free-standing weights in the open economy part. Results indicated an increase in the response rate as the schedule requirements became larger in the closed economy. However, the response rate decreased steadily in the open economy.
