The authors tested whether individually tailored health communications receive more attention from the reader than nontailored health communications in a randomized, controlled trial among student volunteers (N = 24). They used objective measures of attention allocation during the message exposure. In a between-subjects design, participants had to read tailored or nontailored nutrition education messages and at the same time had to pay attention to specific odd auditory stimuli in a sequence of frequent auditory stimuli (odd ball paradigm). The amount of attention allocation was measured by recording event-related potentials (ERPs; i.e., N100 and P300 ERPs) and reaction times. For the tailored as opposed to the nontailored group, results revealed larger amplitudes for the N100 effect, smaller amplitudes for the P300 effect, and slower reaction times. Resource allocation theory and these results suggest that those in the tailored group allocated more attention resources to the nutrition message than those in the nontailored group.
在一项针对学生志愿者（N = 24）的随机对照试验中，作者测试了个性化定制的健康信息是否比非定制的健康信息更能吸引读者的注意力。他们在信息曝光期间使用了注意力分配的客观测量方法。在一项被试间设计中，参与者必须阅读定制或非定制的营养教育信息，同时在一系列频繁的听觉刺激（odd ball范式）中注意特定的异常听觉刺激。通过记录事件相关电位（ERP；即N100和P300 ERP）和反应时间来测量注意力分配的程度。与非定制组相比，定制组的结果显示N100效应的振幅更大，P300效应的振幅更小，反应时间更慢。资源分配理论和这些结果表明，定制组的人比非定制组的人将更多的注意力资源分配到了营养信息上。
