The present study investigated the saliency of form of visual stimulus presentation (printed word or picture) and of the semantic evaluative dimension (positive or negative) as encoding attributes for fifth-grade children. Three short-term memory trials within one visual form of presentation or one pole of the evaluative dimension were followed by a fourth short-term memory trial on which the stimulus material was shifted on one or both attributes (experimentals) or held constant (controls). The recall of the experimental groups consistently exceeded that of the control groups on the shift trial, providing evidence for a release from proaetive inhibition and implying the saliency of both the form of visual stimulus presentation and the evaluative polarity of the stimulus concepts as encoding dimensions.
本研究调查了视觉刺激呈现形式（印刷文字或图片）和语义评价维度（积极或消极）作为五年级儿童编码属性的显著性。在一种视觉呈现形式或评价维度的一个极项下进行三个短期记忆试验后，第四个短期记忆试验中，刺激材料在一个或两个属性上转移（实验组）或保持不变（对照组）。在转移试验中，实验组的回忆成绩始终优于对照组，这为从预期性抑制中释放提供了证据，并暗示了视觉刺激呈现形式和刺激概念的评价极性作为编码维度的显著性。
