They're sometimes referred to as "Extrasensory perception", that is the ability to perceive things using senses which are not the base ones. The things perceived by these extra senses can be excluded from psychosis if in a controlled experiment. For example. One person holds a card with a number in one room. Another person with these senses activated, can then perceive the number correctly a number of times higher or much higher than the chance margin. Several experiments have been made on these phenomenons (which are in fact natural) for decades, with a higher than average degree of success. There's several disclosed papers from CIA for example, describing them in detail.
