Average number of Presses and Weight chart

The chart above is the average number of presses per 30 min. The graph does not look like we expected it to but it makes sense when looking at it. The average number of presses increased from shaping to FR-3 when it hit a peak. There was a decrease in the average number of presses on the FR-5 schedule and after that there was a steady increase in the average number of presses. There was a dramatic increase after Shirley was placed on a variable schedule of reinforcement. 

The chart above is the progression of Shirley's weight throughout the period of training. At the beginning of training Shirley was under her goal weight of 208 grams. However, as training continued it was hard to keep Shirley at her goal weight. Her increase in weight did not seem to have an effect on her performance.
