The short-term reliability and long-term stability of visual habituation and dishabituation in infancy were assessed in a sample of 186 infants from four age groups (3-, 4-, 7- and 9-month-olds) seen for two within-age sessions, and in a sample of 69 infants seen longitudinally at 3, 4, 7, and 9 months of age.

Reports on three experiments that assessed the attentional responses of 4-month-old infants to frequency-modulated sweeps corresponding to the frequency range of adult-to-infant and adult-to-adult intonational patterns. (HOD)

Seven techniques for measuring information processing in infants are proposed to aid in the early identification of mental retardation. The techniques are based on conditioning, attentional, and manual exploration paradigms and could be combined into an assessment battery more valid than current infant IQ tests in predicting later disability.…

In a longitudinal study, infants 6 to 18 months of age were observed in their homes playing with their mothers and with peers to determine how they coordinated attention to people and objects. Person engagement declined with age, while coordinated joint engagement increased; both passive and coordinated joint engagement were much more likely when…

Tested two models of the relationship between a hypothetical attachment mechanism and an incompatible motivation (a tendency to explore) by pitting two levels of attachment motivation against two levels of exploratory motivation among 15- to 18-month-old infants, alternating freely between play with novel toys at one end of the room and visits…

This study investigated potential effects of auditory and other communicative experience on development of visual attention in 80 infants (tested at 9, 12, and 18 months), half deaf and half with deaf mothers. Results indicate that early visual attention is associated with and potentially influenced by a complex interaction of maturation,…
