When we speak of cognition or thought, we speak of the ‘what’ and the ‘how’. The ‘what’ of cognitive therapy refers to the contents of thought: “I’m scared about this or that” etc. The ‘how’ is the process of thought that guided our mind to reach a specific end point. Examples of processes are many; the most common in my own inner repertoire: catastrophizing (every event is colored with intense shades of negativity) and obsessing, which is just a nice way of saying circular thinking done in the loneliness of a solitary mind, cut off the friendship of others.
