The mode-control model of counting and timing (Meek & Church, 1983) suggests that discriminations based on number and time may be controlled by the same internal clock mechanism. In Experiment 1, two groups of pigeons were initially trained to perform delayed symbolic matching-to-sample (DSMTS) at a 5s fixed baseline delay, with sample stimuli that consisted of sequences of flashing light. Testing was conducted with a range of delays (0, 2.5, 5, 7.5, and 10s). In the Number Group, control by number was established by varying the number of flashes while holding time constant. In the Time Group, control by time, …
