The early detection of reading and other learning problems is of paramount importance if we are to develop appropriate educational programs before the child has experienced years of failure. Despite the proliferation of kindergarten prediction studies (Book, 1974; Eaves, Ken dall, and Crichton, 1974; Feshbach, Adelman, and Fuller, 1977; Glazzard, 1982; Jansky and deHirsch, 1972; Perry, Guidubaldi, and Kehle, 1979; Satz, Taylor, Friel, and Fletcher, 1978; Taylor and Ivimey, 1980; Telegdy, 1975), there is a continuing concern that our interest in early prediction exceeds our capacity to identify children at risk for future failure (Lindsay and Wedell, 1982; Rubin, Balow, Dorle, and Rosen, 1978). It is possible that in our investigation of children's performance, we are not asking the right questions. The present study was based on the premise that linguis tic factors shown to be critical in the reading process are generally overlooked in kindergarten and first-grade screening instruments. Until recently, the most popular explanation of reading problems focused on purported deficits in visual perception and perceptual-motor skills. Major screening batteries reflected this research emphasis by including a wide range of perceptual-motor tasks (e.g., blocks, puzzles, drawing, sorting). It was not surprising, therefore, to find that training programs based on these batteries emphasized perceptual-motor train ing, almost to the exclusion of other aspects of functioning. Most re searchers now question the visual-perceptual deficit explanation of read ing disability and provide data that directly contradict it (Benton, 1975; Vellutino, 1977, 1979). There is now extensive documentation in the literature of the impor tance of language-based skills in reading achievement (Gleitman and Rozin, 1977; Liberman, 1982; Liberman and Shankweiler, 1979; Liber man, Shankweiler, Liberman, Fowler, and Fischer, 1977; Perfetti and Lesgold, 1977, 1979; Vellutino, 1977, 1979). Several reading-related lan guage measures provide direct evidence of the many facets of linguistic processing, as opposed to visual processing, that are significantly related to reading. Two such tasks—the Liberman-Shankweiler Segmentation
