This paper describes the initial organization of the infant's reaction to having his vision occluded by an opaque cloth; traces the development of this reaction over the first six months; and probes the role the occlusion of vision plays in provoking the reaction. Fifty videotaped sessions of infants during two conditions - eyes covered with an…

A looming paradigm was used to determine what depth information infants process in addition to that provided by the expansion of a single, closed contour of an object. A total of 18 male and 15 female infants aged 22-48 days watched a film in which the circular elements and inter-element spaces of the projected image alternately expanded and…

The objective of this study was to provide intensive, consistent experience in the following developmental areas: relation to objects and vocal and gestural imitation. The curriculum was developed in an inner city industry-based day care center with 14 infants aged 8 to 19 months initially. The Hunt-Uzgiris Scales measuring development in these…

This study investigated the common practice in infant research of eliminating from reported data large numbers of subjects who prove uncooperative (sleepy, fatigued, fussy) during the experiment. It was suggested that these excluded infants constitute a special class of subjects and that the inclusion of their data would greatly alter the research…

Results showed that 2- and 3-dimensional forms affected 4- and 8-week-old infant visual behavior differently. (Author/JMB)

A classification and description of cry types stimulated by different internal sources--hunger, pain, illness and alarm. Various features of each type were distinguished by spectrographic analysis. Pain cries seemed to be the basic type from which other types evolve. Comparisons with other studies were made. (AMH)

Results from this study of 110 low-risk, middle-class infants showed that a significantly greater proportion of infants whose mothers worked full-time outside the home were assigned to the category "insecure-avoidant" than infants whose mothers remained in the home throughout their children's first year of life.

Changes in children's categorization behavior between 15 and 21 months of age and the relation of these changes to developments in language, object permanence, and means-end understanding are reported. (PCB)

To document movement patterns and to examine developmental interrelationships, the ontogeny of rooting, lip, lateral tongue, mouth opening, biting, and Babkin reflexes and the development of emerging chewing behaviors were observed in two normal infants over a period from 1 week to 35 weeks of age. (Author/RH)

Finds that seven-month-old infants are sensitive to pictorial interposition whereas five-month-old infants are not. Suggests that sensitivity to pictorial depth information first appears between five and seven months of age. (Author)

The concurrent and predictive relations of sensorimotor behavior and play to language in the second year were assessed among 19 preterm and 20 full-term infants tested at 13 1/2 and 22 months of age. Numerous associations between play and language were identified; sensorimotor behavior and language in the same age period were relatively loosely…

Thirty-two three-month-old infants participated in two experiments showing color videotapes of facial stimuli in a paired comparison format. Suggests that contrast in effect of eye contact availability and rather subtle stimulus motion (blinking) implies that three-month-old infants are comparatively insensitive to being the object of another's…

An account of studies conducted by author and others concerning Piaget's view of object concept development in infants. (HS)
