Off the top of my head, this is what I remember:
Truisms: What must be true about them?
Ask youself questions like: What do?: "People like ..."; "People hate..." "People (sometimes) think about (themselves/others/events/news-stories/culture/etc)..." Narrow it down to what you observe about the person, obvious things like: "What do women like..."; "What do men look for.." As you gather information about them, you can think more specifically to yourself, "What do doctors worry about?"
List Sort: List possibilities and watch for reaction.
List the possible reactions/beliefs/etc. within some specific topic and watch for physical reactions. Important reactions are blushing/sweating/swallowing/sniffing/hand shuffling/sudden shift in posture/head nods/sighs/ etc.
Tell a story about someone else and notice which parts the person reacts to.
"Some people like the challenges they come up against in work from time to time, others look for opportunities to relax and not do too much of anything at their jobs, they feel to..."
"I knew a guy a while back, when I was in college, and he hated getting on airplanes, being away from his family, having to work hard in a far off place, but he did enjoy the change of scenery..." -- See, you can judge reactions for at least 5 areas just from this: (college/airplanes(heights)/family/working hard/scenery&travel).
Questions: Elicit answers using hidden (and non-hidden) questions.
Ask a yes/no question with a skeptical/nondecisive tone of voice. If they say no, your tone was right; if they say yes, your words were right.
Talk about something you're not sure of and watch for reactions, or them saying "yes, that's right". In the first few minutes, preframe this by telling them that they should tell you whenever they hear anything that connects with them, lightly or deeply, it could be of great significance.
Softeners:
Compliment their openness/cooperation/ability to explore (psychic) possibilities/character traits which they may or may not have. Notice that this can be used in non-psychic contexts; you can replace the above "(psychic)", with "(medical)" or whatever your business is.
Time Truisms: "There are times when you have felt X." X can be anything at all that fits the sentence. Everyone has felt almost everything at times.
In general, add jargon words, refer to the type of psychic technique you're using, and add prefatory phrases that weave through time, space, and thought/emotion process (yours and theirs). Add hedge words, like "probably, seems, it could be that, sometimes, often, never, apparently, this is coming in a little fuzzy but" and negations "it's not that you've never (thought that you were inferior)...", and tag questions "isn't it?, right?". Use figurative language and imagery "It's like you're in a dream world sometimes, what you want seems so close, yet you realize that..." Use factives: "aware, realize, discover, etc." Use words like "search, find, reminded of".
