In a study of the effect of task demands on attention allocation, 20 9-year-olds and 20 13-year-olds were presented with a primary and a secondary task. Subjects were instructed either to respond to the primary task or to respond to both tasks. Overall, findings indicate that ability to allocate attention in accordance with task demands improves…

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)

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…

Contrasts a fixed-rate presentation list with one in which half the items in a single list were presented at a fast rate and half at a slow rate during paired associative learning with 24 children (aged 8 to 22 years) who were diagnosed with having an attention deficit disorder. (HOD)
