A scientist called Carol Fowler has apparently done research that mine is related to. I was told so by Dominic Massaro, at the Visual Prosody workshop in Nijmegen MPI. He said that my findings on sign perception are similar to speech perception. Specifically, a delay of about 90 ms between detection and recognition, which I found for sign perception, was also found for speech perception by Fowler. But which is the literature I should consult?
At the Haskins laboratory she was part of a stream of research in the 1980’s that treated speech as articulatory gestures:
Carol Fowler proposed a direct realism theory of speech perception: listeners perceive gestures not by means of a specialized decoder, as in the motor theory, but because information in the acoustic signal specifies the gestures that form it.
