Along with her husband, Alvin Liberman, she elucidated the " alphabetic principle " and its relationship to phonemic awareness and phonological awareness in reading.
The motor theory of speech perception proposed by Alvin Liberman and colleagues at the Haskins Laboratories argues that the identification of words is embodied in perception of the bodily movements by which spoken words are made.
The theory was initially proposed in the Haskins Laboratories in the 1950s by Alvin Liberman and Franklin S . Cooper, and developed further by Donald Shankweiler, Michael Studdert-Kennedy, Ignatius Mattingly, Carol Fowler and Douglas Whalen.
Lenneberg's biological approach to language was related to developments such as the motor theory of speech perception developed by Alvin Liberman and colleagues at Haskins Laboratories and also provided historical antecedents to issues now emerging in embodied philosophy and embodied cognition.
Alvin Liberman and colleagues { he did not talk about voice onset time in that paper } reported that when people listen to sounds that vary along the voicing continuum, they hear only / ba / s and / pa / s, nothing in between.
