Whitaker, Simon, Lowe, Furgus and Wearden, John (2003) Multiple-interval timing in rats: Performance on two-valued mixed fixed-interval schedules. Journal of Experimental Psychology: Animal Behavior Processes, 29 (4). pp. 277-291. ISSN 0097-7403

Three experiments studied timing in rats on two-valued mixed-FI schedules,
with equally probable components, FI S and FI L. When the L/S ratio was
greater than 4, two distinct response peaks appeared close to FI S and L, and
data could be well-fitted by the sum of 2 Gaussian curves. When the L/S ratio
was less than 4, only one response peak was visible, but nonlinear regression
usually identified separate sources of behavioral control, by FI S and FI L,
although control by FI L dominated. The data were used to test ideas derived
from Scalar Expectancy Theory (SET), the Behavioral Theory of Timing
(BeT), and Learning to Time (LeT).
