phenomenological primitive – a class of implicit knowledge element posited, explored and discussed in the work of Andreas diSessa and his colleagues
"The 'knowledge' elements developed then act at the intuitive level within perception and cognition, as 'black boxes' not open to conscious interrogation. Despite their inaccessibility to introspection, these expectancies about the world can have strong effects in formal learning… and it is argued that much of our accessible conceptual thought is in effect developed by recruiting such tacit elements."
