Development of Planning in Relation to Age, Attention, Simultaneous and Successive Processing
This study investigated the development of planning and its relationship with age and other cognitive processes taken from the PASS model. Ninety-nine students in grades two, four, and eleven were administered planning, simultaneous processing, successive processing, and attention tasks. MANOVA with grade level and gender as independent variables revealed that grade level had a significant effect on planning, whereas gender did not. All but one planning variable showed a significant main effect of grade in subsequent ANOVAs. Pair-wise comparisons between grade levels indicated that the developmental trajectories were not uniform in different tasks. Regression analyses indicated that the co…
Cognitive and neuropsychological profiles of the elderly
Testing the cognitive functions of the elderly is often eclectic and atheoretical. We take a theoretical model, simultaneous and successive processing, and the tests derived from it to describe the cognitive functions of the elderly. Subsequently, the performance of an elderly sample on a battery of neuropsychological tests is examined and also understood in relation to the two processing modes. Subjects were 81 individuals, 75 years old, from a population of nearly 300 persons participating in a Finnish research project on aging. They were administered tests of simultaneous and successive processing as well as an extensive battery of neuropsychological tasks. Multivariate and univariate an…
