“…This is just what happens, the bulk of the second peak being accounted for by attention to the occluder. The first advance is thus occurring at around 17 weeks in this study, a result in accordance with others (Bower et al, 1971;Bower & Paterson, 1973;Mundy-Castle & Anglin, 1973), with the second advance occurring at 22 weeks, well in advance of the age indicated by studies using other indicator behaviours (Uzgiris & Hunt, 1975;.…”

Object concept development was studied longitudinally in a group of 24 infants from 12 weeks until achievement of Stage 6. Infants were tested between 12 and 28 weeks on four visual tracking tasks: a simple, unoccluded tracking task and three others, each involving a different spatial relationship in mid‐track between the object and an occluder (a screen, tunnel, or platform). Competence on manual search tasks was monitored from the age at which reaching first appeared. Understanding of the same three spatial relationships between object and occluder (behind, in and on) was tested. Early exposure to the visual tracking tasks turned out to have a substantial accelerative effect on object concept development. Both the visual and manual data collected lend more support to a three‐advance identity model of object concept development than to the traditional six‐stage Piagetian model.

“…Harris, Cassell and Bamborough (1974) found that 2-month-old infants can already track the movement of an object against a textured field. However, Bower demonstrated that only at around 4 months do infants consistently track intentional and directed object movements (Bower, Broughton & Moore, 1971;Bower & Paterson, 1973;Bower, 1975).…”

Animacy and propulsion in infancy: Tracking, waving and reaching to self‐propelled and induced moving objects

Infants from 16 to 20 weeks were videotaped while being presented with objects traversing a 60 cm distance. Four conditions were tested: (1) induced movement, holding the object; (2) induced movement, pushing the object; (3) selfpropelled mechanical movement, object moving by an internal clockwork; (4) self-propelled biological movement, animate object moving by internal impulse. In tracking, the self-propelled but inanimate and mechanically moving object with the more straight and predictable trajectory attracted most visual attention. In arm movements, the self-propelled but relatively unpredictably moving animate object was reliably distinguished from inanimate objects. It appeared that the action system was less dependent on objects taking a straight and predictable course. Emerging with the onset of goal-directed reaches, the distinction of an internal locus of propulsion in objects was overriding the nearly exclusive response towards animacy occurring in waving. Thus, a distinction of different types of object motion could be found in infants' developing action system.

“…colour and form. Bower, however, has claimed that infants less than 20 weeks of age do not detect these properties of moving objects but simply respond to the movement per se of the object, and this is perceived as something quite different from the same object when stationary (Bower, 1971(Bower, , 1974Bower et al, 1971;Bower & Paterson, 1973). According to this view, when infants are presented with a moving object that stops, the infants think the stationary object is a new object and, conversely, they do not identify a stationary object with itself when moving.…”

Five experiments using the visual preference method (Expt I) and an infant-controlled habituation procedure (Expts 2-5) are described. Their aim was to examine the salience of movement, both rotation and translation, as a stimulus for new-borns, and to investigate under what conditions information about shape can be extracted from stationary and moving stimuli. A moving stimulus, whether rotating or translating, was found to be consistently preferred to an identical stationary stimulus (Expt I). Following habituation to one direction of rotation, no novelty preferences were found for the other direction of rotation (Expt 2); this suggests that clockwise and anticlockwise movements may be comparable for the new-born.The other experiments suggest that new-borns can extract shape information from stationary and moving stimuli, and can transfer what is learned to moving and to stationary stimuli (Expts 3 and 5). This transfer occurred when (a) the spatiotemporal changes caused by stimulus rotation were the same from habituation to post-criterion trials (Expt 3), and (b) orientation did not change (due to the use of translation movement) across conditions (Expt 5). There was no evidence that new-borns could transfer learning from stationary to rotating stimuli or vice versa (Expt 4).This demonstrates that new-borns can perceivea similarity between a stimulus when moving and when stationary, and suggests a degree of visual organization that is not usually attributed to the new-born: Expt 5 in particular suggests that the perceptual potential for identity constancy is present from birth.
