Palacios, Pedro; Rodríguez, Cintia – Infant and Child Development, 2015
In this study, we address the construction of the first symbolic uses of objects in contexts of triadic interaction (adult-child-object). We assume that symbolic productions are based on public rules of the use of objects previously agreed by the community. The first symbols are not rooted in any literal, evident reality, but in shared rules of…

Bigelow, Anne E.; And Others – Merrill-Palmer Quarterly, 1995
Two experiments investigated 8-, 10-, and 12-month-old infants' levels of searching for mothers, strangers, and objects. Found that, overall, 10- and 12-month-old infants had higher levels of searching for mothers, whereas youngest infants showed no differences for searching. This discrepancy is likely due to social cognitive development and…

Ganea, Patricia A. – Child Development, 2005
How do infants come to understand references to absent objects? 14-month-old infants first learned a name for a novel toy, which was then placed out of view. The infants who listened to a story mentioning the nonvisible object, looked, pointed, and searched for it more often than did infants who heard a story using a different name. Their behavior…

Bremner, J. Gavin; Johnson, Scott P.; Slater, Alan; Mason, Uschi; Foster, Kirsty; Cheshire, Andrea; Spring, Joanne – Child Development, 2005
When an object moves behind an occluder and re-emerges, 4-month-old infants perceive trajectory continuity only when the occluder is narrow, raising the question of whether time or distance out of sight is the important constraining variable. One hundred and forty 4-month-olds were tested in five experiments aimed to disambiguate time and distance…

Bertenthal, Bennett I.; Fischer, Kurt W. – Developmental Psychology, 1978
Presents a study of the development of self-recognition in infants from 6 to 24 months of age. The development of self-recognition is compared to the development of object permanence. (BD)

And Others; Jackson, Elaine – Developmental Psychology, 1978
Presents a study of decalage between object permanence and person permanence. Decalage was influenced by environmental as well as stimulus factors with infants tested between 6- and 81/4-months/of-age. (BD)

Aguiar, Andrea; Baillargeon, Renee – Cognitive Psychology, 2002
Eight experiments were conducted to examine 3- and 3.5-month-old infants' responses to occlusion events. The results revealed two developments, one in infants' knowledge of when objects should and should not be occluded and the other in infants' ability to posit additional objects to make sense of events that would otherwise violate their…

Campos, Joseph J.; Ramsay, Douglas S. – Developmental Psychology, 1978
Attempts to determine whether infants' performance in two search tasks is related to their entry into Stage 6 of object permanence development (thereby testing Piaget's claim that only Stage 6 infants possess the capacity for representation). (BD)

Phillips, Shelley – 1982
Prior to considering the ability of infants to think, this discussion attempts to dispel prevalent myths about babies' thought processes. The fact that infants do not intentionally manipulate their parents; are not identical; are not simply hedonistic seekers of bodily pleasures; and are not passive, disorganized beings needing training into…

Shimada, Shoko; And Others – 1979
The purpose of this study was to cross-sectionally and longitudinally examine the developmental process of search behavior in infancy. Subjects were 23 Japanese normal infants (11 males and 12 females) who were individually tested once a month from the age of six to 13 months in laboratory settings. Small toys and three white opaque cubic boxes…
