Abstract
The concepts of spatial-simultaneous and verbal-successive processing are explored, and their relevance to reading quantified. In simultaneous processing, perceived stimuli are totally surveyable or globally available at one point in time, whereas in successive processing information is presented consecutively in serial order as in speech. Comparison of the two systems of processing makes it possible to distinguish the reader with the ability to convert the consecutive presentation of elements of incoming information into a new quality of simultaneous perceptibility from one who may have a good understanding of the meaning of individual words but not grasp the meaning of the thought as a whole. The results of this investigation confirm previous studies that in grades 4 and 5 both forms of processing, spatial and verbal, are important in normally achieving children. The relative influence of the two systems at different ages and achievement levels, as well as implications for training, is discussed.
