This study investigated the relationship between task difficulty and blink activity, which includes blink rate, blink amplitude, and blink duration. Two kinds of tasks established two levels of difficulty. In Exp. 1, a mental arithmetic task was used to examine the relationship. Analysis showed that blink rate for a difficult task was significantly higher than that for an easier one. In Exp. 2, a letter-search task (hiragana Japanese alphabet) was used while the other conditions were the same as those in Exp. 1; however, the results of this experiment were not influenced by the difficulty of the task. As results indicate that blink rate is related to not only difficulty but also the nature of the task, the nature of the task is probably dependent on a mechanism in information processing. The results for blink amplitude and blink duration showed no systematic change during either experiment.
本研究调查了任务难度与眨眼活动之间的关系，眨眼活动包括眨眼频率、眨眼幅度和眨眼持续时间。两种任务设定了两个难度级别。在实验1中，使用了一项心算任务来检验这种关系。分析表明，困难任务的眨眼频率明显高于较简单任务的眨眼频率。在实验2中，使用了一项字母搜索任务（日语平假名字母），而其他条件与实验1相同；然而，该实验的结果不受任务难度的影响。由于结果表明眨眼频率不仅与难度有关，还与任务的性质有关，任务的性质可能取决于信息处理中的一种机制。在两个实验中，眨眼幅度和眨眼持续时间的结果均未显示出系统性变化。
