Haake, Robert J.; Somerville, Susan C. – Developmental Psychology, 1985
Nine- to 18-month-old infants were presented with simple two-location manual search tasks involving invisible displacements of objects with sequence of displacements occurring before infants search. Results provided insights into age differences associated with development of logical search strategies, information-processing skills, and temporal…

Byrnes, James P.; Overton, Willis F. – Developmental Psychology, 1986
Examines the development of the child's concepts of certainty and uncertainty within the context of concrete and propositional reasoning tasks. Subjects were first, third, and fifth graders. Findings support the position that reasoning about concrete certainty and uncertainty requires a different competence than that required for reasoning about…
