parapraxis

a freudian slip, or parapraxis, is an error in speech, memory or physical action that is believed to be caused by the unconscious mind. some errors, such as a man accidentally calling his wife by the name of another woman, seem to represent relatively clear cases of freudian slips. in other cases, the error might appear to be trivial or bizarre, but may show some deeper meaning on analysis. a freudian slip is not limited to a slip of the tongue, or to sexual desires. it can extend to our word perception where we might read a word incorrectly because of our fixations. it is important to note that these slips are semi-conscious. this is to say that these thoughts are consciously repressed and then unconsciously released. this is unlike true freudian repression which is the unconscious act of making something unconscious.

the freudian slip is named after sigmund freud, who described the phenomenon he called fehlleistung (literally meaning faulty action in german, but termed as parapraxis in english) in his 1901 book the psychopathology of everyday life.
