We present behavioral and anatomical evidence for a multi-component reading system in which different components are differentially weighted depending on culture-specific demands of orthography. Italian orthography is consistent, enabling reliable conversion of graphemes to phonemes to yield correct pronunciation of the word. English orthography is inconsistent, complicating mapping of letters to word sounds. In behavioral studies, Italian students showed faster word and non-word reading than English students. In two PET studies, Italians showed greater activation in left superior temporal regions associated with phoneme processing. In contrast, English readers showed greater activations, particularly for non-words, in left posterior inferior temporal gyrus and anterior inferior frontal gyrus, areas associated with word retrieval during both reading and naming tasks.

Italian children (n = 125) were classified into dyslexics, poor readers and ordinary readers. The dyslexics were further classified into the Boder and Bakker subtypes. The children were tested with the form-resolving field (FRF), which measures central and peripheral visual recognition. Dyslexics show higher correct identification of letters in the periphery, supporting the notion of a different distribution of lateral masking. A numerical characterization of individual FRFs--C2R--reliably distinguishes between dyslexics and ordinary readers. The wider distribution of recognition, similar across the various subtypes of dyslexia, suggests a general characteristic of visual perception, and possibly a different visual-attentional mode.

The aim of this study was to evaluate some Children's Depression Inventory (CDI) psychometric properties and the prevalence of depressive symptoms in an unselected Italian sample of two hundred and eighty-four children aged 8 years. The CDI internal consistency was adequate (Cronbach's alpha:.80). The mean and standard deviation of CDI and the percentage of children at risk of depression (10.6%) in this sample are consistent with the figures reported by other studies carried out in northern Europe and North America. There were differences in gender and socioeconomic level in that boys scored higher than girls, and in the lower socioeconomic level there were more children at risk of depression. Ten items best discriminated children at risk for depression with 94% of correct classification. Most of these items consisted of observable signs. It is suggested that the CDI has noteworthy consistency across samples of relatively different cultures, that it can reliably be employed in the assessment of young children, and that observable signs outnumber internalizing symptoms of depression among children at risk
