Spatiotemporal identity in infancy: Perceptual competence or conceptual deficit?

Although a few developmental fMRI studies have shed some light on the neurological development of either object or spatial processing we still know very little about the development of the 'what' and 'where' processing systems. The present study is the first to address this issue by comparing, concurrently and within the same behavioral paradigm, patterns of functional activation for face processing and location processing in 12 children (10-12 years old) and 16 adults. For both tasks this study found a developmental shift from a more distributed pattern of activation in children to a more focused pattern of activation in adults. Furthermore, the type of developmental redistribution of activation in children varied depending on the task. The present findings have important implications for theories of visuospatial development. They suggest that the neural systems involved in face and location processing may undergo development and fine-tuning well into late childhood.

To investigate why 3-year-olds have difficulty in switching sorting dimensions, children of 3 and 4 years were tested in one of four conditions on Zelazo's card sort task: standard, sleeve, label and face-up. In the standard condition, children were required to sort blue-truck and red-star cards under either a blue-star or red-truck model card, first by color or shape, and then by the other dimension. Here 3-year-olds sorted correctly until the dimension changed; they continue to sort by the initial dimension. The sleeve condition (placing the sorting cards in an envelope prior to sorting) had little effect. In the label condition, the child labeled the relevant sorting dimension on each trial. Most 3-year-olds succeeded; evidently their labeling helped them refocus their attention, overcoming 'attentional inertia' (the pull to continue attending to the previously relevant dimension). In the face-up condition, attentional inertia was strengthened because sorted cards were left face-up; 4-year-olds performed worse than in the standard condition. We posit that attentional inertia is the core problem for preschoolers on the card sort task.Doublethink means the power of holding two contradictory beliefs in one's mind simultaneously, and accepting both of them. (George Orwell, 1984)
