Analyzes conversations between one mother and her 22-month-old child, describing sequences the pair used in clarifying each other's focus of attention and in instructing and learning about concepts and motor skills. Results highlight the importance of the intensive learning environment provided by home conversations. (RH)

Interactions of adults with a single infant, dressed as either a male or female, were recorded and analyzed for direction of gaze, facial expression, physical contact, and toys used. Interviews followed. Results shows that both male and female parents behave differently toward unfamiliar infants on the basis of perceived sex. (AOS)

Three children were observed in their homes approximately once a month for one year, from their 11th through 22nd month of life. Based on observation of the children's changing nonverbal behaviors, a five-level developmental sequence documenting the evolution of the cognitive notion of agent was developed. (Author)

Fifteen pairs of twins were investigated as to the influence of pre-walking practice in an infant walker on the onset time of independent walking. A one-way analysis of variance indicated there was no significant difference between the mean ages of initial walking for the experimental and control groups. (Author/PN)

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)

In two studies, photographs of facial expressions of normal and Down's syndrome infants were viewed by mothers who recognized discrete emotions and reported regularities in caregiving associated with these emotions. Stimulating interactions were reported more frequently for high intensity expressions than for low intensity expressions. High…

Differences in response of four- to seven-month-old infants to tachistoscopically presented photographs of two human faces suggest infants were able to remember a frequently presented face from trial to trial and discriminate it from a discrepant, infrequently presented face. Findings suggest event-related brain potential (ERP) responses could…

Confirms that aftereffects of prism adaptation can be obtained in infants between 5 and 9 months of age and that the magnitude of these aftereffects is comparable to those found in adult studies. Evidence of a shift in hand preference toward the direction of prism displacement was replicated. (Author/RH)

This study was designed to investigate the development of the visual placing response in infants, as well as the visual mediation of the response and texture factors that influence this response during its development. The response was associated with age and apparently developed in two phases. (Author/DB)

Nine- and 16-month-old infants were presented a manual search problem in which a toy was hidden in one of two inaccessible containers, which were then moved into reach. Older infants performed better than younger infants, performance improved across trials, and more correct searches occurred when containers or trajectories were distinctive.…

Results of two studies were consistent with the view that 3-month-old infants perceive movement in depth during their own movement. They can move to avoid a surface just prior to contacting it. (Author/RH)

To assess the effects of the onset of mothers' inaccessibility to their infants, infant-mother pairs were observed in the Ainsworth strange situation at both 12 and 18 months and were classified as secure, anxious-avoidant, or anxious-resistant. Children of mothers who had returned to work/school before their child was 12-months-old were more…

Training was found to increase both parents' and infants' competence in the parent-infant dyad. A reciprocal relationship between increases in the trained fathers' interactions and decreases in the trained mothers' interactions was found, indicating that the triad may be the crucial unit for studies of parental competence.
