“…The manual skills established during infancy underlie a wide range of human abilities, including the intelligent behavior associated with tool construction and use (Lockman, 2000), representational reasoning (Streri & Feron, 2005;Needham, 2000;Piaget, 1952), and the adaptive comprehension of the environment (Striano & Bushnell, 2005). Manual actions are both an expression of knowledge and a means of acquiring it.…”

Expression of multiple object management skills (manual acquisition and storage of objects) was examined longitudinally at 7, 9, 11, and 13 months for 38 infants (19 females) whose hand use preference was either stable (consistently right or left across the ages) or nonstable (either no hand-use preference exhibited or inconsistent preference across the ages). Four separate sets of four distinctive objects each were presented singly to the infant's right and left side, with the presentation of each subsequent object contingent on the infant manipulating the previous object. Expression of multiple object management skills significantly increased with age. Infants with stable hand-use preferences produced more object acquisition and storage acts than those without a stable hand-use preference. Older infants with stable hand-use preferences exhibited more "sophisticated" sequences of multiple object management acts than those without. The role of stable hand-use preference in the development of manual skill and cognition is discussed.

“…Even though already younger infants can perceptually differentiate between different materials (e.g. Striano & Bushnell, 2005) and weights (e.g. Itier et al, 2001), our findings demonstrate that infants do not start to use material information to guide their actions with differently weighted objects before 11 months of age.…”

Two studies with 9-, 11-and 13-month-old infants were conducted to investigate infants' ability to use an object's material properties to guide their object-directed actions. In study 1, 9-and 11-month-old infants played in an exploration phase with two objects made of different materials, one very heavy and the other one light and playable. Subsequently, when given the choice between both objects in a preferential reaching task, only the 11-month-olds' used the object's material information to remember and choose the lighter object. In study 2, 11-and 13-monthold infants underwent the same exploration phase. In the test phase, novel objects made of the same materials were offered. The 13-but not the 11-month-olds chose the objects made from the same material as the lighter object in the exploration phase. Additionally, infants' performances in the reaching task were positively correlated with their exploratory behaviour during the exploration phase. Altogether, the studies show a developmental progression in the use of an object's material information to guide infants' action. The results are discussed in respect to infants' perception of object properties and their implications for the development of physical knowledge.

“…A baby's earliest explorations of himself and his environment are made using his sense of touch ( [2], [3]), his hands and mouth being the principal exploratory tools. [4] presented evidence for genuine haptic perception of material properties (including weight differences) by infants as young as three months old, although they did not explore the objects with hand movements specific to the properties in question (which is due to their inability to move the fingers independently). The stimuli consisted of objects which were all held with the same kind of grip, in order that they could not be discriminated on the basis of hand posture and in total darkness to avoid visual perception or cross modal associations, in other words to make the exploration purely haptic.…”

Abstract-One of the key aspects of understanding human intelligence is to investigate how humans interact with their environment. Performing articulated movement and manipulation tasks in a constantly changing environment, have proven more difficult than expected. The difficulties of robot manipulation are in part due to the unbalanced relation between vision and haptic sensing. Most robots are equipped with high resolution cameras, which images are processed by well established computer vision algorithms such as color segmentation, motion detection, edge detection, etc. However, the majority of robots have very limited haptic capabilities. This paper presents our attempt to overcome this difficulties by: (a) using a tendon driven robotic hand with rich dynamical movements and (b) covering the hand with a set of haptic sensors on the palm and the fingertips, the sensors are based on a simplified version of an artificial skin with strain gauges and PVDF (polyvinylidene fluoride) films. The results show that if the robotic hand actively explores different objects using the exploratory procedures: tapping and squeezing, material properties such as hardness and texture can be used to discriminate haptically between different objects.
