对14、20和26周龄的婴儿进行纵向研究。他们在电视屏幕上看到了各种复杂的图案。三分之二的陈述伴随着外围的刺激，从对中央刺激的注视开始就延迟了。与之前的研究一样，婴儿在心率最大减速点出现时不像在心率反应结束时出现时那样容易受到干扰刺激的分心。在减速定义的试验中，基线记录中有大量呼吸性窦性心律失常(即心率变异性)的婴儿比呼吸性窦性心律失常量较少的婴儿更不容易分心。呼吸性窦性心律失常在测试年龄内的个体内发展模式与持续注意期间的心率反应模式密切相关。心率和呼吸性窦性心律失常基线水平的个体差异比持续注意的个体差异更稳定。注意反应随年龄增长的稳定性可能由生理系统的稳定性(如心率、呼吸性窦性心律不齐等)和注意心率变异性的年龄内关系所调节。
Infants were studied at 14, 20, and 26 weeks of age in a longitudinal design. They were presented with varying and complex patterns on a TV screen. Two‐thirds of the presentations were accompanied by a stimulus in the periphery delayed in time from the onset of fixation on the central stimulus. As in previous research, the infants were not as easily distracted by the interrupting stimulus when the presentation occurred at the point of maximal heart rate deceleration as when the presentation occurred at the end of the heart rate response. Infants with large amounts of respiratory sinus arrhythmia (i.e., heart rate variability) in a baseline recording were less distractible during the deceleration‐defined trials than were infants with low amounts of respiratory sinus arrhythmia. Intra‐individual patterns of development in respiratory sinus arrhythmia over the testing ages were closely paralleled by patterns of heart rate responding during sustained attention. Individual differences in baseline levels of heart rate and respiratory sinus arrhythmia were more stable than individual differences in sustained attention. The stability of attention responses over age may be mediated by the stability of the physiological system (e.g., heart rate, respiratory sinus arrhythmia, etc.), and by the within‐age relation of attention to heart rate variability.
