This study tested the hypothesis that failure in active visuospatial working memory tasks involves a difficulty in avoiding intrusions due to information that is already activated. Two experiments are described, in which participants were required to process several series of locations on a 4 x 4 matrix and then to produce only the final location of each series. Results revealed a higher number of errors due to already activated locations (intrusions) compared with errors due to new locations (inventions). Moreover, when participants were required to pay extra attention to some irrelevant (non-final) locations by tapping on the table, intrusion errors increased. Results are discussed in terms of current models of working memory functioning.
在主动视觉空间工作记忆任务中出现失误涉及到难以避免因已激活信息而产生的干扰。文中描述了两项实验，要求参与者处理4×4矩阵上的几组位置信息，然后只给出每组的最终位置。结果显示，与因新位置（虚构）产生的错误相比，因已激活位置（干扰）产生的错误数量更多。此外，当要求参与者通过敲击桌子对一些无关（非最终）位置给予额外关注时，干扰错误增加。本文根据当前工作记忆功能模型对结果进行了讨论。
