Michael Siegal (March 30, 1950 – February 20, 2012) was a developmental psychologist and cognitive scientist who was Marie Curie Chair in Psychology at the University of Trieste, Italy, and was a Professor of Psychology at the University of Sheffield, UK.
His research sought to determine how access to language, language acquisition, and participation in conversation influence cognitive processes in development and their breakdown in adulthood following brain damage, especially in the areas of numerical, spatial, social, and moral cognition. This work was carried out in different cultures and involves monolingual and bilingual children, atypically developing children such as deaf children, and adults with aphasia.
