当前的定向模型表明定向反应和注意加工之间的关系。使用两个独立的探测技术，以指数注意处理：二次反应时和惊吓眨眼修改这种关系进行了研究。28名大学年龄段的受试者接受了混合的“待参加”和“待忽略”音调的演示。在音调的一个子集期间获得皮肤电导定向反应。其余的每一个音调都包含在150或2,000 ms的导联间隔处的次级反应时间探针或在120或2,000 ms的导联间隔处呈现的惊吓眨眼探针。此外，在选定的音调间隔期间也呈现反应时间和惊吓探针，对这些刺激的反应作为基线，从该基线比较由注意和忽略的音调产生的反应时间和眨眼幅度的变化。结果显示，与忽略的音调相比，注意的音调与较大的皮肤电导定向反应，在120 ms导联间隔下更大的眨眼抑制，在2，000 ms导联间隔下更大的眨眼促进，以及在2，000 ms导联间隔下更大的反应时间减慢相关。与之前的研究结果一致，在150 ms导联间隔下，忽略音调与反应时间减慢的相关性大于关注音调。结果支持的皮肤电导定向反应和注意力过程的启发之间的关系，并建议二次反应时间和眨眼修改技术可以提供关于这种关系的独特信息。
Current models of orienting suggest a relationship between the orienting response and attentional processing. This relationship was examined using two independent probe techniques to index attentional processing: secondary reaction time and startle eyeblink modification. Twenty‐eight college‐age subjects received intermixed presentations of to‐be‐attended and to‐be‐ignored tones. Skin conductance orienting responses were obtained during a subset of the tones. Each of the remaining tones contained either a secondary reaction time probe at lead intervals of 150 or 2,000 ms or a startle eyeblink probe presented at lead intervals of 120 or 2,000 ms. In addition, reaction time and startle probes also were presented during selected intertone intervals, and responses to these stimuli served as the baselines from which to compare changes in reaction time and blink amplitude produced by the attended and ignored tones. The results revealed that, compared with the ignored tones, the attended tones were associated with larger skin conductance orienting responses, greater blink inhibition at the 120‐ms lead interval, greater blink facilitation at the 2,000‐ms lead interval, and greater reaction time slowing at the 2,000‐ms lead interval. Consistent with previous findings, the ignored tone was associated with greater reaction time slowing than was the attended tone at the 150‐ms lead interval. The results support a relationship between elicitation of the skin conductance orienting response and attentional processes and suggest that the secondary reaction time and blink modification techniques may provide unique information regarding this relationship.
