According to the myers-briggs type indicator, we have preferred ways of thinking and behaving that can be divided into four categories. which category identifies how we focus our attention as well as our sources of energy?

I believe the answer is: extrovert-introvert

According to the myer briggs indicators, extroverted people tend to be able to focus their attention in group setting and would obtain energy from social interraction. The introverts on the other hand, would be able to focus their attention if they work alone, and their energy would be drained when they're forced to be in social interaction.
