Hi! My name is Blake Eastman. My entire life has been dedicated towards three things. Psychology, Poker, and Nonverbal Behavior.
Over the past 6 years I have lead a team that has conducted the largest behavioral study ever conducted on poker players. This was an extensively labor intense process which required the Recording, Tagging, and Analysis of thousands of hours of video. Let me explain exactly what we did.
We start our process with recording poker players and creating behavioral datasets. Our studies utilize RFID poker tables and between 6-10 camera angles to record every single movement at the poker table. We also utilize psychophysiological instruments such as the Empatica E4 to collect additional data focusing on different states of physiological arousal. Our recording efforts are ongoing and we currently have close to 200 terabytes of raw footage of both cash games and tournaments ranging from micro to high stakes
In order to perform the level of analysis we require, we need to tag and code every movement and action at the table: every bet, check, call, raise, fold, blink, smile, smirk, weird facial movement, and word spoken, it's all coded using both qualitative and quantitative methods. In order to code such a large database, we use automated and manual coding procedures, meaning that when a computer isn’t tagging facial expressions, a member of our research team is manually coding every single action at the table.
To analyze this massive dataset, we have created what we call the CAT (Contextual Analysis Tool), which combines all of the players’ hands and every action at the table with every single behavior and when it exactly occurs within 1/30th of a second. This way we can see how actions, hand strength, and behavioral events impact behavior at the table. This gives us the ability to answer any question we have about the relationship between behavior and actions at the table. For example, what does an increase in blink rate in post flop situations mean?
