Table 1. Sequence of conditions arranged in Experiments 1 and 2. Components changed after 10 food deliveries: Thus, when eight magazine-light presentations per component were arranged, components changed after an average of 18 events (food or magazine light). The value of r in Experiment 2 is the correlation of magazine-light and green-keylight presentation ratios with food ratios.
Condition | Arranged number of magazine-light presentations per component |
Experiment 1 | |
1 | 0 |
2 | 2 |
3 | 4 |
4 | 6 |
5 | 8 |
Experiment 2 | Correlation (r) between magazine light ratios, and green keylight ratios, with food ratios |
6 | Magazine light r = −1.0 |
7 | Magazine light r = 0 |
8 | Magazine light r = +1.0; Green keylights r = −1.0 |
9 | Magazine light r = −1.0; Green keylights r = +1.0 |
