In the Jan. 28, 2015 of their Rundmail, Basler-Psi-Verein, one of the Swiss promoters of Psychology of Vision for-profit events claims Chuck Spezzano is an "internationally renowned psychologist."

Yet again I need to point out that Spezzano's 1977 Ph.D. was apparently
in something exotic called "Professional Psychology." It was not
accredited by the APA, which means his diploma bypassed any sort of
national standard. Even in Germany this should disqualify him from being
called a "psychologist."
In addition, Spezzano was fined by the State of Hawaii in 2004 for
impersonating a professional. He is not licensed and is not even
remotely qualified to practice professional psychology even if he
applied. Here are some links to some primary sources of interest so you
can see the evidence:
