What is the state of the art in computerised coding of Thematic Apperception Tests (TATs)?
The state of the art in computer-scored Thematic Apperception Tests (TAT) as of 2015 appears to be that computer-scored TATs do not exist. 

There does not appear to be any relevant results on Google Scholar, Web of Science or Scopus for any search I can think of including the term "thematic apperception" which yield any example or mention of computer-scored TATs, and all recent studies utilizing TATs have reported using standard versions (e.g., Turk et al., 2010). A 2013 book dedicated to the TAT, A practical guide to the Thematic Apperception Test: The TAT in clinical practice also fails to make any mention of computer-scored or otherwise computerized implementations of the TAT.
