Two<sup>***</sup>Present study was intended to explore the boundary condition of the list-strength effect, that is repeated items in a list inhibit recall of nonrepeated items. The results of seven experiments showed that mere presence of repeated items in a list is not necessary condition of the list-strength effect. List-strength effects were found when intralist repetition with relatively large set size occurred in a block and close to test. Repeated items were recalled significantly earlier than nonrepeated items in output positions of recall curve. Thus, temporal cue should be considered as a constraint of the list-strength effect in recall. No current memory model seem to explain such boundary conditions of the effect.
