摘要：

When trained in a symbolic choice-matching task involving short (2-s) and long (10-s) durations as samples, pigeons tend to choose the comparison associated with a short sample as delay increases (choose-short effect). The present experiments showed that the choose-short effect can be eliminated by training in many-to-one (MTO) procedures in which 2 or more sets of sample stimuli are associated with 1 set of comparison stimuli. It is concluded that (a) the choose-short effect results from a process of subjective shortening that occurs during a delay if duration samples are coded analogically and (b) samples of duration are coded nonanalogically in at least some MTO mapping arrangements.
