The stability of the OR habituation rate as an individual difference trait was investigated in 2 studies. The 1st focused on motor OR's to auditory stimuli at 3 ages within the 1st month of life, and the 2nd examined the HR responses to auditory stimuli at 4 and 8 months. The results indicate that motor OR's did not differ significantly with age and were moderately stable across ages. The stability decreased with age across consecutive days but increased across consecutive weeks. The cross-age correlation for HR responses was moderate. The results were compared with similar findings on other parameters of the OR.
在两项研究中对定向反射（OR）习惯化率作为个体差异特征的稳定性进行了调查。第一项研究聚焦于出生后第一个月内三个年龄段对听觉刺激的运动OR，第二项研究则考察了4个月和8个月大时对听觉刺激的心率（HR）反应。结果表明，运动OR并未随年龄有显著差异，且在不同年龄段具有中等程度的稳定性。这种稳定性在连续几天内随年龄下降，但在连续几周内上升。HR反应的跨年龄相关性为中等。将这些结果与关于OR其他参数的类似发现进行了比较。
