Twyman, Alexandra; Friedman, Alinda; Spetch, Marcia L. – Developmental Psychology, 2007
We used a reference memory paradigm to examine whether 4- and 5-year-old children could be trained to use landmark features to relocate targets after disorientation. In Experiment 1, half of the children were pretrained in a small equilateral triangle-shaped room. Each of the three walls was a different color, and the target was always in the…

Wilcox, Teresa; Woods, Rebecca; Chapa, Catherine; McCurry, Sarah – Developmental Psychology, 2007
Recent research indicates that by 4.5 months, infants use shape and size information as the basis for individuating objects but that it is not until 11.5 months that they use color information for this purpose. The present experiments investigated the extent to which infants' sensitivity to color information could be increased through select…

Melkman, Rachel; Rabinovitch, Liora – Developmental Psychology, 1998
Examined object concept development in 2- to 4-year olds with a partial replication of a study by Spelke and Kestenbaum (1986). Found that children judged identical entering and exiting figures as involving one object and different figures as involving two objects. Continuity of movement failed to affect judgments of numerical identity. Findings…

Ross, Gail; And Others – Developmental Psychology, 1992
Premature infants with subependymal or intraventricular hemorrhage took longer to habituate on a habituation task, and scored lower on a measure of mental development, than did other premature infants or full-term infants. Both groups of premature infants were less successful than full-term infants on an object permanence task. (BC)

Eizenman, Dara R.; Bertenthal, Bennett I. – Developmental Psychology, 1998
Three experiments examined 4- and 6-month-olds' sensitivity to the unity of a partly occluded moving rod undergoing translation, rotation, or oscillation. Findings suggested that all types of common motion were not equivalent for specifying infants' perceptions of occluded objects. (Author)

Rose, Susan A.; And Others – Developmental Psychology, 1991
Measures of visual and tactual recognition memory, tactual-visual transfer, and object permanence were obtained for preterm and full-term infants. Measures of tactual-visual transfer were correlated with later intelligence measures up to the age of five years. These correlations were independent of socioeconomic status, medical risk, and early…

Johnson, Scott P.; Aslin, Richard N. – Developmental Psychology, 1995
Examined perception of object unity in partial occlusion in 72 infants. Recorded how long subjects looked at a display of complete and incomplete rods. In test and control conditions, infants looked longer at broken rods than at complete rods, suggesting that infants' cognitive, visual, or attentional skills may be insufficient to support…
