WebThe Psycholinguistic Grain Size Theory was developed to explain cross-language variation in reading acquisition, namely, that children learning to read in a deep orthography lag behind children learning to read in a shallow orthography (e.g. Seymour et al., 2003). According to this theory, while readers of shallow orthographies can reliably WebThe hydrometer analysis is a widely used method of obtaining an estimate of the distribution of soil particle sizes from the #200 (0.075 mm) sieve to around 0.001 mm. The data are plotted on a semi-log plot of percent finer versus grain diameters to represent the particle size distribution.
