作者调查了情绪图片刺激是否特别可能在旁视中被处理。成对的情绪和中性视觉场景被呈现为旁视（从中央注视点的2.1度或2.5度视角）150- 3000英寸，然后进行立即识别测试（500毫秒延迟）。结果表明：（a）被试的第一注视点更倾向于放在情绪场景上，而不是中性场景上;（B）当场景配对时，情绪场景的再认敏感度（A '）普遍高于中性场景，但当场景单独呈现时，两者之间没有差异;（c）对情感场景的上级敏感度在大小、颜色和空间方向的变化中幸存下来，但在意义上却没有。这些数据表明，情感场景的语义分析可以开始在旁视提前中央凹固定。
The authors investigated whether emotional pictorial stimuli are especially likely to be processed in parafoveal vision. Pairs of emotional and neutral visual scenes were presented parafoveally (2.1 degrees or 2.5 degrees of visual angle from a central fixation point) for 150-3,000 ins, followed by an immediate recognition test (500-ms delay). Results indicated that (a) the first fixation was more likely to be placed onto the emotional than the neutral scene; (b) recognition sensitivity (A') was generally higher for the emotional than for the neutral scene when the scenes were paired, but there were no differences when presented individually; and (c) the superior sensitivity for emotional scenes survived changes in size, color, and spatial orientation, but not in meaning. The data suggest that semantic analysis of emotional scenes can begin in parafoveal vision in advance of foveal fixation.
