The tongues of 34 infants between 31 and 40 weeks estimated gestational age were stimulated with filament esthesiometers. Stereotyped ipsilateral movements of the tongue were elicited in all infants. An assessment of tactile sensitivity based on this reflex is minimally affected by infant activity state and habituation to repeated stimulation. Small pre-term infants (31 to 35 weeks gestation) and infants born near term (37 to 40 weeks gestation) were more sensitive to tactile stimulation than an intermediate group (35 to 37 weeks gestation). In infants followed longitudinally, a transient decrement in sensitivity occurred at two weeks postnatal age. The tactile sensitivity in 12 adults (as measured by their correct reports of stimulus location) was far greater than the sensitivity of the infants.
用丝状触觉测量仪刺激了34名孕龄估计在31至40周之间的婴儿的舌头。所有婴儿均引发了刻板的同侧舌部运动。基于这种反射的触觉敏感性评估受婴儿活动状态和对重复刺激的习惯化影响最小。小早产儿（孕龄31至35周）和近足月儿（孕龄37至40周）比中间组（孕龄35至37周）对触觉刺激更敏感。在纵向随访的婴儿中，出生后两周时敏感性出现短暂下降。12名成年人的触觉敏感性（通过他们对刺激位置的正确报告来衡量）远高于婴儿的敏感性。
