About Michael Long

Michael Hugh Long was an American psycholinguist. He was a Professor of Second Language Acquisition at the University of Maryland, College Park. Long introduced the concept of focus on form, which entails bringing linguistic elements to students’ attention within the larger context of a meaning-based lesson in order to anticipate or correct problems in comprehension or production of the target language. Long contrasted this approach with the older method of focus on forms, which calls for exclusive focus on the linguistic forms when teaching a target language, often consisting of drill-type exercises such as conjugation exercises. Long is also usually credited for introducing the Interaction Hypothesis, a theory of second language acquisition which places importance on face-to-face interaction.
