Abstract
Haptic texture perception was investigated in 3-day-old infants. Following a habituation sequence with a smooth or granular object, babies received a haptic test during which they held either the familiar or a new textured object. Two dependent measures were recorded: (1) Holding time was used to assess habituation as well as reaction to novelty and (2) hand pressure frequency exerted on the object was used to investigate neonates’ capacity to adjust their manipulation to the texture of objects. Both measures revealed neonates’ capacity to haptically perceive the texture of objects. From the results, it can be concluded that neonate’s manual cyclical activity recorded by HPF is a primary exploratory tool that is both necessary and sufficient to obtain knowledge about texture.
