“Conditions Affecting Beliefs about Visual Perception among Children and Adults”, 1996 (; backlinks; similar):
Tested groups of children and adults on their beliefs about whether visual processes involved intromissions (visual input) or extramissions (visual output) across a variety of situations.
The present research showed that when questions about vision referred to luminous as opposed to non-luminous objects, under certain conditions there was some increase in intromission beliefs, but almost no corresponding decline in extramission beliefs, and no evidence of transfer of intromission responses to questions referring to non-luminous objects.
A separate study showed that college students, but not children, increased their extramission responses to questions providing a positive emotional context.
The results are inconsistent with the idea that simple experiences increase or reinforce a coherent theory of vision.
