The aim of the paper is to establish firmly the phenomenon of an irrelevant picture effect and to demonstrate that the phenomenon can be used to investigate the characteristics of the visuo-spatial sketchpad. Experiment 1 introduces the use of dynamic visual noise as an interfering technique. This technique is shown to cause interference with a word list learned under visual mnemonic mediation instructions but to cause no interference when the word list is learned under verbal mediation instructions. Experiment 2 serves both to replicate this selective interference effect and to illustrate how the dynamic visual noise technique can be used to characterize further the nature of interference in the visuo-spatial sketchpad. Experiment 3 confirms the robustness of the dynamic visual noise technique. Additionally, this experiment demonstrates a double dissociation between two types of interference, dynamic visual noise and irrelevant speech, and two types of mediation, rote and visual mnemonic.
本文的目的是确凿地确立无关图片效应这一现象，并证明该现象可用于研究视觉空间画板的特征。实验1介绍了使用动态视觉噪声作为一种干扰技术。结果表明，该技术会干扰在视觉记忆中介指导下学习的单词列表，但在言语中介指导下学习单词列表时不会产生干扰。实验2既用于复制这种选择性干扰效应，也用于说明动态视觉噪声技术如何可用于进一步刻画视觉空间画板中干扰的性质。实验3证实了动态视觉噪声技术的稳健性。此外，该实验还证明了两种干扰类型（动态视觉噪声和无关言语）与两种中介类型（机械记忆和视觉记忆）之间的双重分离。
