Pigeons discriminated visual stimulus duration in a psychophysical choice procedure. Following short durations, one of two responses was reinforced; following long durations, the other response was reinforced. Discrimination accuracy decreased as a function of increasing dose level of d-amphetamine. Decrements in accuracy were greater for two of three pigeons following long-than following short-stimulus durations. Position response biases increased as dose level incraesed. Similar effects of the drug on behavior occurred over two temporal ranges of stimulus durations studied.
