It remains unknown whether their high levels of musical interest, skill, and expressivity are related to their sociable…

Analogue functional analyses are a well-researched means of determining behavioral function in research and clinical contexts. However, conducting analogue functional analyses in school settings can be problematic and may lead to inconclusive results. The purpose of this study was to compare the results of a trial-based functional analysis with…

Italian developmental dyslexic readers show a striking length effect and have been hypothesised to rely mostly on nonlexical reading.
