Nicked from a parapsychology website - experiments which have shown positive results for psychic abilities:

1) The SHEEP/GOATS effect. 'Sheep' are people who are relatively open-minded and are ready to at least accept the possibility of something new, and 'goats' are those who dig their heels in. The 'sheep' score significantly higher in card guessing experiments.

(2) The DECLINE effect. If you ask a person to guess 100 packs of Zener cards, their scores decline as they get bored until, nearing the end of the task, their scores improve again. Prof. Roy showed how the graph of scores differed from chance results.

(3) The HELMUT SCHMIDT effect. An arrangement of nine lights lit up randomly, driven by the radioactive decay of Strontium-90. People were asked to guess which lamp would light up next. A follow-up experiment with nine lights in a circle showed that people could force the lamps to light in a clockwise sequence, an example of psycho-kinesis or P.K.

(4) The GANZFELD experiment, developed by the late Charles Honorton, has been improved by the Koestler Unit in Edinburgh. People in a daydream existence, their senses diminished by diffuse light and sound, attempt to describe pictures which are being viewed in another room. Results of 36% compare with 25% expected by chance. Over many studies, this represents a chance of one in ten million.
