On phi-phenomena.
The meaning of "phi" in Max Wertheimer 's 1912 article on seen movement (the publication of which marks the beginning of Gestalt psychology) and the import of the article itself were topics of a report in this Journal. The claims made in that report are questioned here, and a different interpretation of phi and the original article is offered.
