Prior research suggests that infants' action production affects their action understanding, but little is known about the aspects of motor experience that render these effects. In Study 1, the relative contributions of self-produced (n = 30) and observational (n = 30) action experience on 3-month-old infants' action understanding was…

In some areas of rural Africa, long-standing cultural traditions and beliefs may discourage parents from verbally engaging with their young children. This study assessed the effectiveness of a parenting program designed to encourage verbal engagement between caregivers and infants in Wolof-speaking villages in rural Senegal. Caregivers (n = 443)…

Infants imitate others' individual actions, but do they also replicate others' joint activities? To examine whether observing joint action influences infants' initiation of joint action, forty-eight 18-month-old infants observed object demonstrations by 2 models acting together (joint action), 2 models acting individually (individual action), or 1…

Researchers have suggested that as children's language skill develops in early childhood, it comes to help children regulate their emotions (Cole, Armstrong, & Pemberton, 2010; Kopp, 1989), but the pathways by which this occurs have not been studied empirically. In a longitudinal study of 120 children from 18 to 48 months of age, associations…

This study relies on eye tracking technology to investigate how humans perceive others' feeding actions. Results demonstrate that 6-month-olds (n = 54) anticipate that food is brought to the mouth when observing an adult feeding herself with a spoon. Still, they fail to anticipate self-propelled (SP) spoons that move toward the mouth and manual…

This study investigated the hypothesis that background television affects interactions between parents and very young children. Fifty-one 12-, 24-, and 36-month-old children, each accompanied by 1 parent, were observed for 1 hr of free play in a laboratory space resembling a family room. For half of the hour, an adult-directed television program…

Two studies were conducted to investigate how 14- to 16-month-old infants select actions to imitate from the stream of events. In each study, an experimenter demonstrated two actions leading to an interesting effect. Aspects of the first action were manipulated and whether infants performed this action when given the objects was observed. In both…

Infants aged 9, 14, 20 and 24 months were observed looking at picture books with their mothers. The integration of pointing with verbal and visual behaviors together with activities pertaining to the task, such as page turning, are described. (Author/JMB)

Investigated relationships between mothers' perception of infants temperament at 6 months and their behavior toward their infants at 6 and 12 months of age among 40 firstborn Israeli infants. Temperamental intensity ratings were related to auditory stimulation and contingent positive vocalization for girls and to increased physical contact for…

A total of 204 male and female subjects rated an infant's emotional responses to four arousing stimuli. Half of the subjects were told they were observing a "boy" and the other half a "girl". Significant differences in responding were found by sex attributed to the child, sex of rater, and the rater's experience with young children. (Author/JMB)

A sample of 40 babies was observed in a variety of mildly challenging situations throughout their second year and in a series of follow-up assessments at age 31/2. Findings revealed two types of avoidant mechanism--wariness of the unfamiliar and fearfulness after exposure to a mildly difficult situation. (JMB)

Investigates the developmental sequence of learning to transform objects into agents and recipients of action in early symbolic play. Each of 48 children (from 14 to 25 months old) demonstrated initiative pretending after an adult modeled agent and recipient substitutions in pretending to talk on the telephone. (Author/CB)

In a naturalistic behavioral stdy, it was found that prematures have significantly more endogenous smiling than full-term newborns. (Authors)
