Three experiments are presented that deal with the effect of stimulus probability on the encoding of both alphanumeric characters and nonsense figures. Experiment I replicated a previous finding of an interaction between stimulus probability and stimulus quality in a memory scanning task with numbers as stimuli. Experiments II and III investigated the same paradigm with unfamiliar visual forms as stimuli, and no interaction was found. Results were interpreted as showing that probability affects the encoding mechanism only when the encoding process results in a representation of the name of the stimulus. When stimulus materials are visual forms without names, probability does not appear to affect encoding processes.
呈现了三个实验，这些实验涉及刺激概率对数字等字母数字字符和无意义图形编码的影响。实验一复制了先前在数字作为刺激的记忆扫描任务中发现的刺激概率和刺激质量之间相互作用的发现。实验二和实验三使用不熟悉的视觉形式作为刺激，研究了相同的范式，没有发现相互作用。结果解释为表明，只有当编码过程导致刺激名称的表示时，概率才会影响编码机制。当刺激材料是没有名称的视觉形式时，概率似乎不会影响编码过程。
