Active touch in late‐preterm and early‐term neonates

Abstract: An infant-controlled tactile habituation without visual control procedure was used to evaluate the ability of 32 late-preterm neonates (mean gestational age: 34 weeks) and 32 early-term neonates (mean gestational age: 38 weeks) to actively explore with hands objects varying in texture (smooth, granular). Holding time and Hand Pressure Frequency (HPF) were recorded. Holding time decreased as habituation progressed in both group of neonates. Holding time increased from habituation trials to test trials only in e… Show more

“…Differences in the skin cornification processes in utero and in a NICU setting may explain the finding. Differences in the haptic perception of premature infants during their NICU stay may be relevant for the changes in the reflex threshold, particularly in comparison with term infants .…”

“…With the advancement of technological devices, novel methods emerged for assessing motor function in early infancy [ 7 , 14 , 15 , 16 , 18 , 19 , 42 , 43 ]. In particular, grasping behavior was studied in infants in terms of strength and holding time, with some studies proposing novel systems to investigate the relationship of these variables with intrinsic (e.g., infant sex [ 15 ], weight [ 27 ], preterm birth [ 1 ]) and extrinsic factors (e.g., object shape and texture [ 7 ]). Moreover, systems for objective assessment of grasping actions were developed to detect early abnormal neuromotor development and based on the premise that this could guide prompt intervention to improve functional outcome [ 43 , 44 ].…”

“…Moreover, systems for objective assessment of grasping actions were developed to detect early abnormal neuromotor development and based on the premise that this could guide prompt intervention to improve functional outcome [ 43 , 44 ]. The main findings of the state-of-the-art showed a higher grasping strength and pronounced handedness symmetry in males more than females [ 15 ]; a decrease in holding time when the same object was repetitively put in the newborn infant’s hand and an increase when its shape and smoothness changed [ 7 ]; and longer holding times in preterm in comparison to term neonates with significant differences related to sex [ 15 ].…”

“…Hands also play a major part in directing attention through pointing (Daum, Ulber, & Gredebäck, 2013). Moreover, starting early in life, hands are used to explore the world haptically (Molina et al, 2015; Rochat, 1989). However, very little is known about infants’ representation of hands.…”
