As part of a study to determine whether visual and manual response systems are correlated, 26 children between 40 and 51 months of age took part in visual and manual reaction time (RT) tasks. Subjects, whose RTs had previously been tested at 3 months of age, were tested in 1 of 2 conditions. In the first condition, subjects viewed pictures only…

Discussing findings from three studies, this report focuses on questions mothers ask their children while looking at picture books and recent family photographs. In the first study, 30 mothers and their 12-, 15-, and 18-month-old children "read" a simple ABC book that had one picture for each letter in the alphabet. In the second study,…

Home movies of eight normal children and eight children later diagnosed as autistic were analyzed based on: (1) Piagetian criteria of sensorimotor development and semiotic functioning, and (2) developmental levels of action competencies. The age range covered was 4 to 42 months of age. The analysis showed that, from the second year of life, timing…

The Knowledge of Child Development Inventory (KCDI), which is appended, is a 56-item multiple choice test of knowledge of child development from birth to age three.

This volume is the first in "The Course of Life" series which contains original contributions from an international group of scientists and clinicians who have produced much of the current knowledge about the phases of human personality development. These contributions cover the continuum of human development from the prenatal phase…

This research reports the development of a semantic differential for rating nonverbal style of expressiveness in a population of expectant mothers. Mothers' nonverbal features (facial expression, gestures, voice quality) were emphasized as uniquely valid indices of emotional attitudes towards parenthood and as the principal forms of interpersonal…

This paper reports the progress of an ongoing clinical research project on prevention services for at risk infants of mentally ill mothers.

THE EXPERIMENTAL HYPOTHESIS OF THIS STUDY WAS THAT THE MOTIVATIONS FOR SCRIBBLING ARE (1)…

Fixation time, smiling, vocalization, and fret/cry were recorded to obtain a complete picture of infants' responses to facial stimuli over the first year of life. Four stimuli were presented to 120 infants. Results of fixation data indicate that (1) there is a marked decrease in fixation toward facial stimuli within the first year, (2) at all ages…

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…
