The acquisition of reading skill was studied in 503 Italian children in first to eighth grade using a task that required reading
of lists of words and non-words. Analysis of the metric characteristics of the measures indicated that reading speed but not
accuracy was normally distributed across all ages considered. The role of specific effects (length, word frequency, and lexicality)
versus global factors in reading speed was examined using the Rate–Amount Model (RAM). A global processing factor accounted
for a large portion of the variance. Specific influences of length, frequency, and lexicality were detected in different periods
of development over and above the global processing factor. Length modulated performance at early stages of learning and progressively
less later on; in the case of non-words, the effect of length was large but did not change as a function of grade. The lexicality effect, present at all ages for high frequency words and by third grade for low frequency words increased with reading practice
indicating a progressive differentiation in the ability to read words and non-words. Finally, the effect of word frequency
was highest in third grade and then decreased. These findings are discussed in terms of their relevance for reading acquisition
in a language with transparent orthography and their implications for evaluating developmental reading deficits. Overall,
it is proposed that RAM is a useful tool for disentangling the role of specific versus global factors in reading development. 相似文献

The present study examined the use of narrative categories and mental state words in the fictional, personal, and hypothetical stories written by 150 children in the third, fourth, and fifth grades of primary school. There were three main results. First, children were better able to write fictional and hypothetical than personal stories, when considering the total number of narrative categories and the percentages of stories including at least one complete episode. Second, there was clear evidence of differentiation between the three tasks, both in terms of narrative categories and mental state language. Third, the use of mental state words correlated with the frequency of subordinate propositions and the number of narrative categories included in the stories. These findings support the hypothesis of a bidirectional interaction between lexical and syntactic development and suggest that narrative writing involves metalinguistic abilities directly related to the spontaneous use of psychological lexicon. Educational implications are discussed. 相似文献

The room-temperature photoluminescence spectra of various samples of Egyptian blue (CaCuSi4O10) are presented, discussed and compared with those of recently synthesized compounds corresponding to the ancient pigments Han blue (BaCuSi4O10) and Han purple (BaCuSi2O6). All the samples of Egyptian blue show identical spectra, in spite of their very different origin. The spectra of Han blue and Han purple are significantly different. Since the Cu2+ ion may be considered the only luminescent centre in the spectral range under investigation, the differences between the spectra of the various pigments are ascribed to a ligand-field change. This can be related to the larger size of the Ba2+ ion with respect to Ca2+. The use of PL spectra for the identification of these pigments in works of art is proposed. 相似文献
