The recall of picture and word triads was examined in three experiments that manipulated the type of distraction in a Brown-Peterson short-term retention task. In all three experiments recall of pictures was superior to words under auditory distraction conditions. Visual distraction produced high performance levels with both types of stimuli, whereas combined auditory and visual distraction significantly reduced picture recall without further affecting word recall. The results were interpreted in terms of the dual coding hypothesis and indicated that pictures are encoded into separate visual and acoustic processing systems while words are primarily acoustically encoded.
在三项实验中，对图片和单词三联体的回忆进行了研究，这些实验在布朗-彼得森短期记忆任务中对干扰类型进行了操控。在所有三项实验中，在听觉干扰条件下，图片的回忆优于单词。视觉干扰对两种类型的刺激都产生了较高的表现水平，而听觉和视觉相结合的干扰显著降低了图片的回忆，同时并未进一步影响单词的回忆。结果根据双重编码假说进行了解释，表明图片被编码到单独的视觉和听觉处理系统中，而单词主要是通过听觉进行编码。
