Impatience, one major Type A characteristic, alters the performance of tasks requiring anticipation and accurate responding. Beat-by-beat changes in heart rate are also known to occur during anticipatory attention. In college- and middle-aged adult samples, impatience is related to these beat-by-beat heart rate changes during anticipatory attention. The objective of the current study was to see if this relationship was also present in children classified by the impatience-aggression scale of the Matthews Youth Test for Health, a measure of children's Type A behaviors. In study 1, 34 fifth-grade boys performed a modified Pong task. In study 2, 30 fourth-grade boys performed a variable interval simple reaction time task. In both studies, patient and impatient boys showed different beat-by-beat heart rate responses. The results were generally, but not wholly, consistent with the view that impatience leads to a late developing and quickly recovering but robust deceleration at the time of an anticipated event. Consistencies as well as inconsistencies of our findings with the results from college- and middle-aged samples are discussed.
急躁是A型人格的一个主要特征，它会影响需要预期和准确反应的任务表现。在预期性注意力过程中，心率也会逐搏变化。在大学生和中年成年人样本中，急躁与预期性注意力过程中的这些逐搏心率变化有关。本研究的目的是探讨这种关系是否也存在于根据马修斯青少年健康测试的急躁-攻击量表分类的儿童中，该量表用于测量儿童的A型行为。在研究1中，34名五年级男孩完成了一项改良的乒乓任务。在研究2中，30名四年级男孩完成了一个可变间隔简单反应时任务。在两项研究中，耐心和急躁的男孩都表现出不同的逐搏心率反应。结果总体上（但并非完全）与以下观点一致：急躁会导致在预期事件发生时出现较晚发展且迅速恢复但强烈的心率减速。我们将讨论研究结果与大学生和中年样本结果的一致性和不一致性。
