title: Advancing schedules and constant light produce faster resynchronization of circadian rhythms.
abstract: House sparrows, Passer domesticus, were subjected to rotated light-dark (LD) cycles that consisted of repeated 8-hr advances or delays of 5 days of LD 8:16, with intervening 40-80 hr of constant dark or light. Sparrows reset the fastest (by the second cycle) when they were advanced with intervening constant light (LL). They reset the slowest (taking six cycles) when they were delayed with intervening constant dark (DD).
