前摄干扰可能影响工作记忆广度任务的预测效用。在一个实验中（N = 70）的参与者完成了乌鸦先进的进步矩阵（RAPM）和多个版本的操作跨度和探测回忆，修改的类型的备忘录（数字或单词）。改变备忘录内或跨试验释放PI，但不这样做允许PI积累。PI构建试验的分数，而不是PI发布试验，与RAPM相关，并解释了RAPM中与未修改任务一样多的方差。这些结果是一致的控制注意和抑制帐户的工作记忆，他们阐明了工作记忆广度任务的一个基本组成部分。
Proactive interference (PI) may influence the predictive utility of working memory span tasks. Participants in one experiment (N = 70) completed Ravens Advanced Progressive Matrices (RAPM) and multiple versions of operation span and probed recall, modified for the type of memoranda (digits or words). Changing memoranda within- or across-trials released PI, but not doing so permitted PI buildup. Scores from PI-build trials, but not PI-release trials, correlated with RAPM and accounted for as much variance in RAPM as unmodified tasks. These results are consistent with controlled attention and inhibition accounts of working memory, and they elucidate a fundamental component of working memory span tasks.
