Is Freuds theory of negation testable and does it survive testing?
The correct translation of Verneinung in English is denial. Roy Baumeister, Karen Dale, and Kristin Sommer (2002) have reviewed empirical evidence for (or against) seven of Freud's defense mechanisms and have found that "denial [has] been amply shown in studies". You can read about the findings in detail in the article itself, which is currently avialable online here.
