Abstract

Two groups of pigeons were trained to peck a response key under an automaintenance procedure. Once key pecking was \ reliably maintained, all birds were exposed to a trace conditioning procedure. Each bird was successively exposed to trace durations of 1, 2, 4, and 8 seconds. In general, as \ the duration of the trace condition increased, the percent of trials with at least one response decreased; pecking did not shift to the trace stimulus.
