On Estimating Processing Variance: Commentary and Reanalysis of Kail's "Developmental Functions for Speeds of Cognitive Processes."

Morrison, G. Rolfe; And Others

Journal of Experimental Child Psychology, v54 n3 p288-307 Dec 1992

An error in the data analysis for a study reported in a 1988 paper by Kail is cited. The paper postulated a model that explained individual differences in the speed of processing on cognitive tasks. Reanalysis of the data suggested that support for the original conclusions is considerably weaker than reported. (LB)
