Children's sensitivity to the quality of epistemic reasons and their selective trust in the more reasonable of 2 informants was investigated in 2 experiments. Three-, 4-, and 5-year-old children (N = 90) were presented with speakers who stated different kinds of evidence for what they believed. Experiment 1 showed that children of all age groups…

Caregiver-infant transactions with 51 premature infants were studied in naturalistic observations in the home when the infants were aged 1, 3, and 8 months. Gesell developmental schedules and a sensorimotor scale were administered at 9 months. (Author/JH)

Attention to others' activity increased with age in children ages four to six. Subjects who showed stable gains in performance level across sessions engaged in more observation of others' activity than did subjects who showed only temporary gains. Subjects who showed no gains observed others' activity least. (Author/RH)

Two studies examined preschool teacher and child interactions regarding personal, moral, and socioconventional issues in the classroom and the development of personal concepts.

Fourteen fathers were observed with their children in unstructured and semistructured situations at home. Mothers and children were also observed, with and without fathers.
