The question: Is a person’s recall for hypnagogic images better when they are in the theta state?

One day seminar - two parts:
Morning (3 hr) - lecture & disc. on Hypnagogia & biofeedback
Afternoon (5 hr) - 4 EEG training periods
practiced observing & coding H.I.s arising in theta state
60 days later recall test mirrored this afternoon sessionThe Participants
Complete a demogr. info sheet and disc. familiarity with: EEG, H.I., & ASCs
EEG devices were Discovery Eng. 2000
EEG recorded at occipital & parietal lobes
900 Hz feedback tone for Alpha, 400 Hz feedback tone for Theta, no tones selected for Beta and Delta
Participant heard tones via ear phonesStimuli and Apparatus
Instructed all participants that in afternoon session each of them would complete 4 identical EEG and H.I. training sessions.

Given randomly assigned file tab and asked to recall in detail for recording
Tested on all H.I.s from training session
