TOT states should be distinguished from FOK (feeling of knowing) states. FOK, in contrast, is the feeling that one will be able to recognize ⁠ ⁠—  from a list of items ⁠ ⁠—  an item that is currently inaccessible. There are still currently opposing articles of the separability of the process underlying these concepts. However, there is some evidence that TOTs and FOKs draw on different parts of the brain. TOTs are associated with the anterior cingulate, right dorsolateral prefrontal cortex, and right inferior cortex while FOKs are not.
