Answer to Question 2
A scallop effect often occurs with fixed interval schedules of reinforcement. Because the end of the interval is predictable, there is often little responding early in the interval. However, as the end of the interval nears, responding tends to increase to higher rates, peaking at the end of the interval. Following the end of the interval, responding again decreases to low levels until the end of the interval approaches again. On a cumulative graph, this results in a visual pattern that resembles a scallop.
