A perturbation paradigm was employed to assess 3- and 6-month-old infants' and their mothers' sensitivity to a 3-s temporal delay implemented in an ongoing televised interaction. At both ages, the temporal delay affected infant but not maternal behavior and only when implementing the temporal delay in maternal (Experiment 1, N = 64) but not infant…

Presented neonates with lexical and grammatical words prepared from natural maternal speech. Found that neonates could categorically discriminate the sets based on a constellation of perceptual cues that distinguished them. Suggested that this ability to discriminate words on basis of multiple acoustic/phonological cues provides a perceptual base…

A report is presented which relates to a general hypothesis suggested by previous data on visual response to faces that in the first weeks of life infants develop expectations regarding the human face. Three predictions were made: (1) Silent human faces would elicit less direct regard than faces accompanied by voices; (2) A familiar face would…

This study explored the relationship between the mother-infant interaction and the concurrent perceptual-cognitive and intellectual status of the infant. One hundred and eight-nine 12-week-old infants were given a battery of perceptual-cognitive tasks, including the Mental Developmental Index (MDI) of the Bayley Scales, the Corman-Escalona Scales…

This study investigates three types of reciprocal interactions among members of the family unit (father, mother and infant): father-infant interaction affecting child's development, father-infant interaction affecting mother's behavior, and husband-wife interaction affecting mother's behavior. Data from a sample of 39 healthy first-born infants…

This study examines the relationship between mother-infant behavior and the infant's performance on perceptual-cognitive tasks as a function of the infant's sex. A total of 189 12-week-old infants and their mothers were observed in their homes during 2 hours of infant awake time. In addition, the Mental Development Index (MDI) of the Bayley Scales…

Twenty infants, 12 weeks of age, were subjects in an experiment to test the effects of maternal behavior on their perceptual-cognitive development. Each mother and child were observed in a controlled naturalistic setting, every 10 seconds their various behaviors were recorded, and then the mother was interviewed. During an experimental session the…

This paper describes the purposes and procedures of a longitudinal study designed to: (1) relate mother-infant interaction patterns to infant age, sex, and social class; (2) relate mother-infant interaction patterns to infant sensory-motor development; and (3) to examine the relationship between infant sensory-motor development and infant sex and…

The third Fenno-Hungarian Conference on Developmental Psychology covered four main concepts: the historical roots and development of social competence through three generations, parent-child interaction, parenthood, and the development of socio-cognitive competence through childhood and adolescence. A series of papers was presented addressing the…
