Freezing+of+Cognition

"the process where the individual does not attempt to develop or test new ideas or entertain new hypotheses." (Pintrich et al, 179)

"The individual does not seek out new information or discounts relevant information that might contradict already established beliefs or knowledge structures that are activated in that situation." (Pintrich et al, 1993, p. 179)

This seems to be a very generalized term that would fit anyone that is not internally nor externally motivated.
