Linnea Carlson Ehri is an American educational psychologist and expert on the development of reading.[1][2] She is a Distinguished Professor Emerita of Educational Psychology at the Graduate Center of the City University of New York.[3][4] Ehri is known for her theory of orthographic mapping,[5][6] which describes the process of forming "letter-sound connections to bond the spellings, pronunciations, and meanings of specific words in memory"[7] that underlies fluent reading. As a consequence of orthographic mapping, written words are tightly linked with their pronunciations and meanings in memory and can be recognized by sight.
In addition to her theory of orthographic mapping, Ehri is best known for her work describing the four stages of learning to read words, referred to as pre-alphabetic, partial, full, and consolidated alphabetic phases.[19] Over time and with practice, readers are able to read familiar words by accessing them directly from memory––a process Ehri called sight word reading.[20]
Since her retirement in 2018, Ehri has continued advising students and collaborating on research on emerging readers[21][22] and evidence-based reading instruction.[23][24]
