Daily Homework question

I’m new to SCS and confused about the daily homework. I understand Thought Downloads, but am unclear about Unintentional/Intentional thought patterns. (I apologize if there is an explanation in the material that I overlooked – there’s so much good stuff there to read and learn :-). Is an Unintentional thought pattern a negative thought taken from the thought download section and applied to the model, and an Intentional Thought Pattern a different, more positive thought about the same circumstance used in the model?

Thanks for clarifying!
