5009C23-2 LECT General Dianetics, Part 2 If you want to test unconscious recall, use a subject with full sonic recall and inflict a little pain to give an anchor point. Use pentothal and nonsense syllables. The best dianetic auditors are writers. You can do straightwire from age 3 on, and perhaps run grief engrams, but nothing heavier. Generally, a person can run standard auditing from age 8 on. [In this tape, Hubbard gives a lot of information on early attempts at objective validation of dianetics by means of psychological testing.]
