Alessandri, Steven M.; And Others – Developmental Psychology, 1990
A total of 80 infants, divided equally among 4 age groups, participated in a contingency learning task. Of these infants, 48 received an audiovisual stimulus contingent on arm movement, and 32 served as a yoked control group. Findings indicated that exposure to a period in which the infant's expectancy regarding contingent outcomes is violated…

Walters, Clarence P.; Walk, Richard D. – Journal of Experimental Child Psychology, 1974
In this study of the visual placing response (an extension of the paws or arms on approach to a visual surface), infants extended their arms almost as much to a gray surface as to a patterned one. (Author/CS)

Lemly, Elizabeth Baker; Schwarz, J. Conrad – 1979
Two-year-olds' reactions to strangers were related to ratings of their emotionality, sociability and activity and to ratings of parental love and control by both fathers and mothers. Each child received two sessions with strangers, one male and one female. Four times per session a stranger, in a friendly manner, approached each child as it sat in…

Adamson, Lauren; Tronick, Edward – 1977
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…

Ball, William A. – 1975
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…

Winkelstein, Ellen; Wolfson, Gail – 1971
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…

Sheppard, Justine Joan; Mysak, Edward D. – Child Development, 1984
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.

Lewis, Michael; Johnson, Norma – Child Development, 1971
Data from infants unable to complete experimental sessions were compared to those for whom there were complete data. Results suggest that the elimination of large numbers of infants may have a potentially biasing effect on reported data. (Authors)

Longo, Josephine; And Others – Perceptual and Motor Skills, 1982
In two sessions, the duration and tempo of toy play of infants and reaction of frustration were measured. Correlations indicated a general relationship between response persistence during play and attempts to escape frustrating situations. (Author/CM)

Floccia, Caroline; And Others – Journal of Experimental Child Psychology, 1997
Three experiments examined whether newborns are sensitive to an operant-conditioning task involving unprepared relation between a response and a stimuli. Found that newborns tested under the High-Amplitude Sucking procedure were involved in an operant-learning situation, in that an increase in sucking rates could be obtained after an auditory…

Lipsitt, Lewis P. – Merrill-Palmer Quarterly, 1990
Discusses important recent strides in the documentation and understanding of the infant's learning and memory capacity. Focuses on the psychobiology of learning, hedonic mediation of approach-avoidance and learned behavior, infant memory, and critical conditions of infancy and behavioral misadventures. (RJC)
