An ACT-R Model of the Choose-Short Effect in Time and Length.
CogSci(2015)
摘要
Duration of an event tends to be underestimated as it becomes temporally distant (Spetch u0026 Wilkie, 1983). The current study investigated this so-called choose-short effect in time and length in order to reevaluate the claim that the choose-short effect is special to temporal memory (Wearden, Parry, u0026 Stamp, 2002). Participants made discrimination judgments in time or length on a pair of line stimuli separated by a delay. The stimulus presented during delay was varied in time or length. A length manipulation intended to be an analogue of temporal delay induced the choose-short effect in length discrimination. We developed a computational model based on ACT-R memory mechanisms (Anderson et al., 2004) to account for the main results in both time and length. The current results indicate that domain-general memory principles could account for the seemingly unique temporal phenomenon.
