Trial-to-trial feature repetition speeds response times in pop-out visual search tasks. These priming effects are often ascribed to a short-term memory system. Recently, however, it has been reported that a 'build-up' sequence of repetitions could facilitate responses over 16 trials later - well beyond twice the typically reported time course (Vision Research, 2011, 51, 1972-1978). Here, we first report two replication attempts that yielded little to no support for such long-term priming of pop-out. The results instead fell in line with the predictions of a previously proposed computational model that describes priming as short-lived facilitation that decays over approximately eight trials (Vision Research, 2010, 50, 2110-2115). In the second part of this study, we show that these data are consistent with a simple formulation of decay with a single timescale, and that there is no significant priming beyond eight trials.
在弹出式视觉搜索任务中，逐次试验的特征重复会加快反应时间。这些启动效应通常归因于短期记忆系统。然而，最近有报道称，一系列“累积”的重复能够在16次试验后促进反应——这远远超出了通常报道的时间进程的两倍（《视觉研究》，2011年，第51卷，第1972 - 1978页）。在此，我们首先报告了两次重复实验尝试，结果几乎没有为这种弹出式的长期启动效应提供支持。相反，结果符合先前提出的一个计算模型的预测，该模型将启动效应描述为在大约八次试验后衰减的短暂促进作用（《视觉研究》，2010年，第50卷，第2110 - 2115页）。在本研究的第二部分，我们表明这些数据与具有单一时间尺度的简单衰减公式一致，并且在八次试验之后不存在显著的启动效应。
