The Regulation of Negative Reactivity in Infancy: Function and Development.
Peer reviewed Peer reviewed
Stifter, Cynthia A.; Braungart, Julia M. – Developmental Psychology, 1995
Examined the function and effectiveness of certain behaviors in regulating negative arousal in infants who participated in an arm restraint procedure at age 5 months and a toy removal task at age 10 months. Results showed that comforting behaviors were preferred at both 5 and 10 months of age. (MDM)

Learning to Reach: A Mathematical Model.
Peer reviewed Peer reviewed
Berthier, Neil E. – Developmental Psychology, 1996
Presents a mathematical model of the development of reaching behavior in infants, along with the results of two experiments that showed that infant movements could be decomposed into the underlying submovements using a principled method; and the angular error in infant reaches matches the form and magnitude of error assumed by the model.

Neonatal Precursors of Infant Behavior.
Peer reviewed Peer reviewed
Yang, Raymond K.; Moss, Howard A. – Developmental Psychology, 1978
Ninety-two clinically normal infants (48 male, 44 female) were tested at 2 and 90 days of age to examine the continuity of newborn behavior through early infancy across a broad range of behaviors. (MP)

Effect of Self-Produced Locomotion on Infant Postural Compensation to Optic Flow.
Peer reviewed Peer reviewed
Higgins, Carol I.; And Others – Developmental Psychology, 1996
Compared the postural responsiveness of seven-, eight-, and nine-month-old infants. Results indicated greater use of optic flow for postural control after a self-produced locomotor experience. Infants with endogenous (creeping) or artificial (walker) self-produced locomotor experience responded to portions of the optic flow field, whereas…

Infants' Predictive Reaching for Moving Objects in the Dark.
Peer reviewed Peer reviewed
Robin, Daniel J.; And Others – Developmental Psychology, 1996
Thirteen infants were presented with a moving object under two lighting conditions to investigate the role of vision in early reaching. Infants were tested twice, at 5 and 7.5 months of age. The results suggest that proprioceptive feedback and sight of the target allowed for successful reaching with limited visual information, even in relatively…

Object Manipulation and Exploration in Two- to Five-Month-Old Infants.
Peer reviewed Peer reviewed
Rochat, Philippe – Developmental Psychology, 1989
Studied the early development of exploratory behavior in 99 infants of 2-5 months. Results show that there are significant changes in spontaneous multimodal exploration of a novel object between 2 and 5 months. (RJC)

An Event-Based Analysis of the Coordination of Early Infant Vocalizations and Facial Actions.
Peer reviewed Peer reviewed
Yale, Marygrace E.; Messinger, Daniel S.; Cobo-Lewis, Alan B.; Oller, D. Kimbrough; Eilers, Rebecca E. – Developmental Psychology, 1999
Used an event-based approach to study the nature of coordination in 3- and 6-month olds during interaction with their caregivers. Found that infants coordinated their vocalizations and facial actions more than expected by chance. When two communicative events were temporally associated across modalities, one event tended to be embedded within the…

Balancing for Weaknesses and Challenging Developmental Potential: A Longitudinal Study of Mother-Infant Dyads in Apprenticeship Interactions.
Peer reviewed Peer reviewed
Heckhausen, Jutta – Developmental Psychology, 1987
Adopts a longitudinal design to track mother-child developmental change in infant task-related mastery and concomitant maternal behavior. Finds that, as infants gain more mastery across time, mothers gradually withdraw support in terms of concrete, specific and nonverbal means of instruction. Results support a one-step-ahead model for maternal…
