Infants prospectively control reaching based on the difficulty of future actions
Prospective motor control, a key element of action planning, is the ability to adjust one's actions with respect to task demands and action goals in an anticipatory manner. The current study investigates whether 14-month-olds can prospectively control their reaching actions based on the difficulty of the subsequent action. We used a reach-to-place task, with difficulty of the placing action varied by goal size and goal distance. To target prospec…
Predictive Actions
Controlling actions must be done ahead of time because events precede the feedback signals about them. The only way to overcome this problem is to anticipate what is going to happen next and use that information to regulate the ones actions. There are at least 3 types of rules that need to be mastered in order to accomplish this. First, those that regulate physical reality like the laws of nature. Secondly, those that regulate their own body move…
Attention demands influence 10- and 12-month-old infants' perseverative behavior
The present study examined the role of attentional demand on infants' perseverative behavior in a noncommunicative looking version of an A-not-B task. The research aimed at clarifying age-related improvements in the attention process that presumably underlies the development of cognitive control. In a between-subjects design, forty 10-month-olds and forty 12-month-olds were assigned to either a distractor or a no-distractor condition as a means o…
Prospective Control
The concept of action is examined, with particular attention to the ontogenetic origin of actions and their developmental course. It is argued that actions constitute dynamic interactions between an organism and the outside world which, by necessity, have to be future-oriented. The upcoming forces and momenta induced by a movement have to be counteracted before they upset the flow of action and the balance of the body. The encounter with the envi…

Action type and goal type modulate goal-directed gaze shifts in 14-month-old infants
Ten- and 14-month-old infants' gaze was recorded as the infants observed videos of different hand actions directed toward multiple goals. Infants observed an actor who (a) reached for objects and displaced them, (b) reached for objects and placed them inside containers, or (c) moved his fisted hand. Fourteen-month-olds, but not 10-month-olds, anticipated the goal of reaching actions but tracked all the other actions reactively. Fourteen-month-old…
Fitting objects into holes
The authors examined 14- to 26-month-old infants' understanding of the spatial relationships between objects and apertures in an object manipulation task. The task was to insert objects with various cross-sections (circular, square, rectangular, ellipsoid, and triangular) into fitting apertures. A successful solution required the infant to mentally rotate the object to be fit into the aperture and use that information to plan the action. The obje…
Month-Old Infants' Perception of Attention Direction in Static Video Images
Twelve-month-old infants' ability to perceive gaze direction in static video images was investigated. The images showed a woman who performed attention-directing actions by looking or pointing toward 1 of 4 objects positioned in front of her (2 on each side). When the model just pointed at the objects, she looked straight ahead, and when she just looked, her hands were hidden below the tabletop. An eye movement system (TOBII) was used to register…
Infants' Evolving Representations of Object Motion During Occlusion
Infants' ability to track temporarily occluded objects that moved on circular trajectories was investigated in 20 infants using a longitudinal design. They were first seen at 6 months and then every 2nd month until the end of their 1st year. Infants were presented with occlusion events covering 20% of the target's trajectory (effective occlusion interval ranged from 500–4,000 msec). Gaze was measured using an ASL 504 infrared eye‐tracking system.…
The Development of Anticipatory Postural Adjustments in Infancy
Efficient voluntary action requires postural adjustments that compensate for potential balance disturbances before they occur. These anticipatory postural adjustments have been widely investigated in adults, but relatively little is known about their development, especially during infancy. This study examined the early development of anticipatory postural activity in support of pulling action while standing. A total of 34 infants between 10 and 1…

Object perception in infancy
Infants ' perception of object boundaries was studied using reaching and preferential looking methods. In 3 reaching studies, S-month-old infants viewed 2 adjacent or separated objects that were stationary, moved together, or moved separately. Infants reached for the objects as distinct units when they moved separately or were separated in space and otherwise reached for the objects as 1 unit. In the looking study, 3-month-old infants were habitu…
Developmental changes in the organization of prereaching movements
How does the kind and amount of prereaching activity change with age during the period preceding successful grasping of objects, that is, during the first 4 months oflife? This question was studied longitudinally in 23 infants. They were seen every third week from the first week of life to 16 weeks of age. Twelve of the infants were also seen at 19 weeks of age. At each session the subject was presented with an object moving slowly in different w…
Eye-hand coordination in the newborn
Eye–hand coordination in the newborn
Are the arm and hand movements of newborns in any way coordinated with vision? If they are, what are the properties of this coordination? These questions were studied in a situation in which newborns were presented with a slowly moving object. In Experiment 1 the number and distribution of arm-hand movements of 14 infants were examined when the object was either present or absent. It was shown that a higher proportion of movements performed while…
