A researcher investigating operant conditioning conducted the following study. A rat was placed in an operant chamber (Skinner box). Whenever the rat pulled a small silver chain, a food reward was immediately delivered into a feed cup.
Each day for 5 days, the rat spent one 10-minute session in the chamber. The researcher recorded the total number of chain pulls made by the rat during each session.
The recorded frequencies are shown in Table 1 below.
Table 1: Frequency of chain-pulling behavior over five daily sessions
| Day 1 | Day 2 | Day 3 | Day 4 | Day 5 | |
|---|---|---|---|---|---|
| Number of chain pulls | 3 | 11 | 25 | 42 | 56 |
