This study investigated the ability of preterm infants to learn an object shape with one hand and discriminate a new shape in the opposite hand (without visual control). Twenty-four preterm infants between 33 and 34 + 6 gestational weeks received a tactile habituation task with either their right or left hand followed by a tactile discrimination…

The present research investigates newborn infants' perceptions of the shape and texture of objects through studies of the bi-directionality of cross-modal transfer between vision and touch. Using an intersensory procedure, four experiments were performed in newborns to study their ability to transfer shape and texture information from vision to…

After haptic habituation to a ring display, infants perceived the rings in two experiments as parts of one connected object. In both haptic and visual modes, infants appeared to perceive object unity by analyzing motion but not by analyzing figural goodness. (RH)

Two experiments investigated 5-month-old infants' amodal sensitivity to numerical correspondences between sets of objects presented in the tactile and visual modes. A classical cross-modal transfer task from touch to vision was adopted. Infants were first tactually familiarized with two or three different objects presented one by one in their…

Investigates whether tactual habituation without the assistance of vision occurs in four- to six-month-old infants. Additionally tests the relevance of a habituation/reaction to novelty procedure in the tactual modality. Results show clearly that tactual habituation occurs in such infants, just as visual habituation does. (Author/RH)

Four experiments studied the perception of the unity and boundaries of objects by 88 4-month-old infants who manipulated them out of the visual field. Infants perceived the unity/boundaries of these objects by detecting the motion patterns they themselves produced. Discrimination between motion patterns transferred from touch to vision. (SLD)
