Hi this instructable is here to teach you to decipher someone like a behaviourist. I am not a professional behaviourist but I will convey everything I know about deciphering human beings on their acts and ways.
There are many ways to decipher someone, a few examples are on how they act in a group and how they act in a personal conversation. How their facial expressions change in a conversation and on how their vocal pitch changes. These are just the basics that anybody can master with a little practice. If you have any tips or criticisms about this please let me know. Now without further ado here is the instructable.
Step 1: First Step
Ok the fist step is to find a suitable subject for your analysis. Don't go overboard and plan your search like a stalker, just choose someone you know well and who you know is easy to trick.
Step 2: Second Step
Find a calm place where you wont be disturbed and go there. If its a living room or a lounge it doesn't matter just as long as you and your subject is comfortable. To make the ground neutral put on a movie or sports game something that will draw your subjects attention but one that will leave some space for interrogation.
Step 3: Third Step
Sit close to the person but bot overly close you don't want them to feel awkward. Start by asking them small unimportant questions like what is their favorite color or food, something to lay a honesty base ( this method is also used in police interrogations ). Keep a close eye on the subject when you ask them the question and when they answer. Look at their pupils VERY closely if the dilate ( get bigger ) and disdilate then they recognize the keyword you just said like for instance Favorite color. Listen to their voice pitch is their voice pitch stays even they are telling the truth if it gets higher it's a lie and is it drop it is a embarrassing or painful memory.
Step 4: Final Step
And there you are now you know how to read a persons body language and vocal pitch to determine if they lie or tell the truth.
