Figure 1. Procedure of Experiment 1.

Four groups of animals were trained with procedures depicted in the figure.

Rats were given sensory pre-conditioning (SPC) training with Cue A and Cue B. In groups A Early and Pre A B precedes A. In other groups the order was reversed. All groups then experienced first order condition (FOC) in which cue B was either forward or backward paired with food. Cue C was used to bracket the food during FOC. The groups are named to indicate where the subjects might come to expect food relative to the Cue A if they integrate temporal information across the two phases. The potential inferred time of food is indicated by the bracketed asterisk in the third row references the test phase for each group.
