An alternative, more archaic form of autosymbolic; relating to self-symbolic or self-representative meaning and processes.
From 'autosymbolic' plus the archaic '-al' suffix variant. The '-al' ending was more common in older English but is now often replaced by '-ic' in scientific terminology.
Old texts used '-ical' for almost everything (mythical, magical, theatrical), which is why autosymbolical appears in vintage psychology papers—it's the older way of saying what we'd now simply call autosymbolic.
