Previous studies showed that affective valence (positive, negative) influences Stimulus–Response Compatibility (SRC) effects elicited by both relevant and irrelevant spatial dimensions. We tested whether valence influences SRC effects when the irrelevant spatial dimension rather than being conveyed by the entire stimulus location is conveyed by the location of the stimulus’ graspable part, i.e., the Handle–Response (H–R) compatibility effect. Participants saw objects with either a flower, a spider or nothing on their handle and categorized them as kitchen utensils or garage tools through button presses. In Experiment 1, a random presentation of valenced stimuli was used, whereas in Experiment 2 differently valenced stimuli were arranged in different blocks. Furthermore, participants in Experiment 2 could be spider-fearful or not. In Experiment 1, an H–R compatibility effect occurred for response latencies, regardless of whether stimuli presented a negative, positive or no element on their handle. In Experiment 2 the effect occurred only when a positive element was shown on the object's handle. In addition, spider-fearful individuals showed significantly slower responses when the element appearing on the object's handle had a negative valence. These results suggest that the SRC effect observed with pictures of graspable objects may be sensitive to the affective characteristics of stimuli and that approach/avoidance response tendencies may also depend on individual differences (being spider-fearful or not).

先前的研究表明，情感效价（正面、负面）会影响相关和不相关空间维度引起的刺激-反应相容性 (SRC) 效应。我们测试了当不相关的空间维度而不是由整个刺激位置传达时，效价是否会影响 SRC 效应，而是由刺激的可抓取部分的位置传达，即处理-反应 (H-R) 兼容性效应。参与者看到把手上有花朵、蜘蛛或什么都没有的物体，并通过按下按钮将它们归类为厨房用具或车库工具。在实验 1 中，使用了随机呈现的效价刺激，而在实验 2 中，不同效价的刺激被安排在不同的块中。此外，实验 2 的参与者可能害怕蜘蛛，也可能不害怕。在实验一中，响应延迟会发生 H-R 相容性效应，无论刺激在其句柄上呈现的是负面、正面还是无元素。在实验 2 中，只有在对象的手柄上显示正元素时才会出现这种效果。此外，当出现在物体手柄上的元素具有负价时，害怕蜘蛛的个体表现出明显更慢的反应。这些结果表明，用可抓取物体的图片观察到的 SRC 效应可能对刺激的情感特征敏感，接近/回避反应倾向也可能取决于个体差异（是否害怕蜘蛛）。在实验 2 中，只有在对象的手柄上显示正元素时才会出现这种效果。此外，当出现在物体手柄上的元素具有负价时，害怕蜘蛛的个体表现出明显更慢的反应。这些结果表明，用可抓取物体的图片观察到的 SRC 效应可能对刺激的情感特征敏感，接近/回避反应倾向也可能取决于个体差异（是否害怕蜘蛛）。在实验 2 中，只有在对象的手柄上显示正元素时才会出现这种效果。此外，当出现在物体手柄上的元素具有负价时，害怕蜘蛛的个体表现出明显更慢的反应。这些结果表明，用可抓取物体的图片观察到的 SRC 效应可能对刺激的情感特征敏感，接近/回避反应倾向也可能取决于个体差异（是否害怕蜘蛛）。
